# InitRunner > InitRunner is an open-source CLI tool for creating and running AI agents from YAML configuration files. InitRunner lets you define AI agents as YAML role files and run them from the terminal. It supports multiple LLM providers, tools, memory, RAG, guardrails, and multi-agent orchestration. ## Getting Started ### Introduction # Introduction **LLM-friendly docs** — This documentation is also available as [`/llms.txt`](/llms.txt) and [`/llms-full.txt`](/llms-full.txt) for LLM consumption. ## Key Features ### Define - **YAML-first** — Declare agents with a Kubernetes-style `apiVersion`/`kind`/`metadata`/`spec` schema. Readable, portable, version-controllable. - **Multi-provider** — OpenAI, Anthropic, Google, Groq, Mistral, and Ollama. Swap providers by changing one line. - **18 tool types** — Filesystem, HTTP, MCP, shell, SQL, custom Python, audio, web reader, and more. Give agents the capabilities they need. - **Multimodal input** — Attach images, audio, video, and documents to prompts via CLI, REPL, API, or dashboard. See [Multimodal](/docs/multimodal). ### Chat - **Zero-config chat** — Run `initrunner chat` with no YAML file. Auto-detects your API key and starts an interactive session. - **CLI-driven RAG** — Add `--ingest ./docs/` to search your documents directly from the command line. - **Tool profiles** — Use `--tool-profile all` to enable every built-in tool, or `--tools git --tools shell` to cherry-pick. - **Memory flags** — `--memory` (default), `--no-memory`, and `--resume` control chat memory from the CLI. ### Remember - **Built-in RAG** — Ingest documents, chunk, embed, and vector-search with Zvec. No external database required. In chat mode, just add `--ingest ./docs/`. - **Memory** — Three types: semantic, episodic, and procedural. Auto-consolidation distills episodes into durable facts. On by default in chat mode. ### Automate - **Triggers** — Run agents on a cron schedule, file change, incoming webhook, or as a Telegram/Discord bot. Daemon mode included. - **Team mode** — Define multiple personas in one YAML for sequential multi-agent collaboration. - **Multi-agent compose** — Orchestrate multiple agents with delegate sinks and startup ordering. - **Autonomy** — Plan-execute-adapt loops that let agents work through multi-step tasks independently. ### Ship - **API server** — `initrunner serve` exposes any agent as an OpenAI-compatible API with streaming. - **TUI + Web dashboard** — Monitor, inspect, and interact with agents visually. - **One-click cloud deploy** — Deploy to Railway, Render, or Fly.io with pre-loaded example roles and persistent storage. - **Guardrails & audit** — Token budgets, tool limits, content filtering, PII redaction, and full action logging to SQLite. ## Quick Install ```bash pip install initrunner ``` Or use the install script: ```bash curl -fsSL https://initrunner.ai/install.sh | sh ``` Or run with Docker: ```bash docker run --rm -e OPENAI_API_KEY vladkesler/initrunner:latest --version ``` ## Next Steps - [Quickstart](/docs/quickstart) — Get your first agent running in minutes - [Concepts & Architecture](/docs/concepts) — High-level mental model, diagrams, and execution lifecycle - [Examples](/docs/examples) — Complete, runnable agents for common use cases - [Installation](/docs/installation) — All install methods, extras, and platform notes - [Configuration](/docs/configuration) — Full YAML schema reference - [Providers](/docs/providers) — Provider setup and model configuration - [Tools](/docs/tools) — All 18 tool types - [Memory](/docs/memory) — Session persistence and long-term memory (semantic, episodic, procedural) - [Ingestion](/docs/ingestion) — Document ingestion and RAG - [Chat](/docs/chat) — Zero-config chat, role-based REPL, and one-command bot launching - [Telegram Bot](/docs/telegram) — Get a Telegram bot agent running in three steps - [Discord Bot](/docs/discord) — Get a Discord bot agent running in five steps - [Triggers](/docs/triggers) — Cron, file watch, webhook, Telegram, and Discord triggers - [Autonomy](/docs/autonomy) — Autonomous plan-execute-adapt loops - [Guardrails](/docs/guardrails) — Token budgets, tool limits, and automatic enforcement - [CLI](/docs/cli) — Complete CLI reference - [Security](/docs/security) — Security hardening guide - [Team Mode](/docs/team-mode) — Single-file multi-persona collaboration - [Compose](/docs/compose) — Multi-agent orchestration - [Multimodal Input](/docs/multimodal) — Attach images, audio, video, and documents to prompts - [API Server](/docs/server) — OpenAI-compatible HTTP API - [Cloud Deploy](/docs/cloud-deploy) — One-click deployment to Railway, Render, and Fly.io - [Troubleshooting & FAQ](/docs/troubleshooting) — Common issues and frequently asked questions ### Quickstart # Quickstart Get your first AI agent running in under five minutes. ## Prerequisites - Python 3.11 or 3.12 - An API key from a supported provider (OpenAI, Anthropic, Google, Groq, Mistral, Cohere, Bedrock, or xAI) — or a local Ollama instance ## Installation ```bash curl -fsSL https://initrunner.ai/install.sh | sh -s -- --extras all ``` Or with a package manager: ```bash uv tool install "initrunner[all]" pipx install "initrunner[all]" pip install "initrunner[all]" ``` > **Note:** On modern Linux (Python 3.11+), bare `pip install` outside a virtual environment will fail due to [PEP 668](https://peps.python.org/pep-0668/). Use `uv`, `pipx`, or create a venv first. > **Tip:** Not sure which extras you need? `[all]` includes every provider, feature, and interface so everything just works. See [Installation](/docs/installation#extras) for the full list. Or run with Docker (no Python required): ```bash docker run --rm -e OPENAI_API_KEY vladkesler/initrunner:latest --version ``` > **Tip:** Don't want to manage infrastructure? [Cloud Deploy](/docs/cloud-deploy) offers one-click deployment to Railway, Render, and Fly.io — the dashboard comes pre-loaded with example roles. ## Guided Setup Run the intent-driven setup wizard. It asks what you want to build, configures your provider and API key, lets you pick tools, and generates both a `role.yaml` and a `chat.yaml`: ```bash initrunner setup ``` The wizard offers 8 intents: `chatbot`, `knowledge`, `memory`, `telegram-bot`, `discord-bot`, `api-agent`, `daemon`, and `from-example`. See [Setup Wizard](/docs/setup) for all options, non-interactive usage, and the full 13-step flow. ## Start Chatting No YAML needed. `initrunner chat` auto-detects your provider and starts an interactive session: ```bash initrunner chat # auto-detects provider, starts chatting initrunner chat -p "summarize this repo" # send a prompt then enter REPL ``` Add tools and launch bots with flags — no role file required: ```bash initrunner chat --tool-profile all # enable all tools (search, Python, filesystem, git, shell, slack) initrunner chat --ingest ./docs/ # RAG over a folder in one flag initrunner chat --resume # pick up where you left off initrunner chat --telegram --tool-profile all # Telegram bot with all tools initrunner chat --tools git --tools shell # cherry-pick specific tools initrunner chat --list-tools # show available extra tools ``` > **Tip:** `--ingest ./docs/` gives you RAG from a single flag. Combine with `--tool-profile all` to give the agent every tool, or add `--telegram` / `--discord` to launch a bot. See [Chat](/docs/chat) for profiles, security, and the full reference. ## Create Your First Agent In InitRunner, an agent's behavior is defined in a YAML file called a **role** (`role.yaml`). It declares the model, system prompt, tools, and guardrails. There are four ways to create one: | Method | Command | Best for | |--------|---------|----------| | **AI generate** | `initrunner create "a file reader that summarizes documents"` | Fastest start — describe what you want in plain English | | **Template** | `initrunner init --name my-agent --template basic` | Starting from a known pattern (`basic`, `rag`, `daemon`, `memory`, `ollama`, `tool`, `api`, `skill`) | | **Copy example** | `initrunner examples copy file-reader` | Learning from complete, runnable examples | | **Manual YAML** | Create `role.yaml` by hand | Full control over every field | ### AI Generate The fastest way to get started. Describe what you want and InitRunner generates the YAML: ```bash initrunner create "a file reader assistant that can browse and summarize local files" ``` This creates a `role.yaml` in the current directory. Review it, tweak if needed, and run it. ### Template Scaffold from a built-in template: ```bash initrunner init --name file-reader --template basic ``` Available templates: `basic`, `rag`, `daemon`, `memory`, `ollama`, `tool`, `api`, `skill`. ### Copy an Example Browse and copy community examples: ```bash initrunner examples list # browse available examples initrunner examples show file-reader # preview the YAML initrunner examples copy file-reader # copy files to current directory ``` See [Examples](/docs/examples) for the full catalog. ### Manual YAML Create a `role.yaml` by hand for full control: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: file-reader description: A helpful assistant that can read and summarize files tags: - example - filesystem spec: role: | You are a helpful assistant with access to the local filesystem. When the user asks about a file, use read_file to read its contents and then provide a clear, concise answer. Use list_directory to explore the project structure when needed. model: provider: openai name: gpt-4o-mini temperature: 0.2 max_tokens: 2048 tools: - type: filesystem root_path: . read_only: true guardrails: max_tokens_per_run: 10000 max_tool_calls: 10 timeout_seconds: 60 max_request_limit: 10 ``` ## Run the Agent ### Single-shot mode Send a prompt and get a response: ```bash initrunner run role.yaml -p "Read the README and summarize it" ``` ### Interactive REPL Start a conversational session: ```bash initrunner run role.yaml -i ``` ### Resume a session Pick up where you left off (requires `memory:` config): ```bash initrunner run role.yaml -i --resume ``` ### Dry run Test without making API calls: ```bash initrunner run role.yaml -p "Hello!" --dry-run ``` ## Validate a Role Check your YAML before running: ```bash initrunner validate role.yaml ``` ## Level Up Your file-reader agent works, but InitRunner can do much more. Here's how to add memory and RAG to the same agent. ### Add memory Add a `memory` section so the agent remembers across sessions: ```yaml spec: memory: max_sessions: 10 max_resume_messages: 20 semantic: max_memories: 500 ``` Now run with `--resume` to pick up where you left off. For richer memory with episodic tracking and consolidation, see the [Memory](/docs/memory) docs. ### Add RAG Add an `ingest` section to let the agent search your documents: ```yaml spec: ingest: sources: - "./**/*.md" chunking: strategy: paragraph chunk_size: 512 chunk_overlap: 50 ``` Run `initrunner ingest role.yaml` to index, then ask questions about your docs. See [Ingestion](/docs/ingestion) for details. ## Next Steps - [Chat](/docs/chat) — Zero-config chat, role-based REPL, and one-command bot launching - [Tutorial](/docs/tutorial) — Build a complete site monitor agent step by step - [Examples](/docs/examples) — Complete, runnable agents for common use cases - [Installation](/docs/installation) — Extras, platform notes, and development setup - [Configuration](/docs/configuration) — Full YAML schema reference - [Providers](/docs/providers) — All supported providers and model options - [Tools](/docs/tools) — Add tools to your agent ### Chat # Chat Zero-config chat, role-based chat, and one-command bot launching. For the full CLI reference, see [CLI Reference](/docs/cli). ## Prerequisites - InitRunner installed (`pip install initrunner` or `uv tool install initrunner`) - An API key for any supported provider (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, etc.) **or** Ollama running locally - For bot mode: the platform optional dependency (`pip install initrunner[telegram]` or `pip install initrunner[discord]`) ## Zero-Config Chat The fastest way to start chatting. InitRunner auto-detects your API provider and launches a REPL. ### Just run `initrunner` With no arguments in a terminal, InitRunner picks the right action automatically: | Condition | Behavior | |-----------|----------| | TTY + configured (API key present) | Starts ephemeral chat REPL | | TTY + unconfigured (no API key) | Runs setup wizard | | Non-TTY (piped/scripted) | Shows help text | ```bash # Auto-detect provider, start chatting initrunner ``` ### Explicit `chat` subcommand ```bash # Same as bare `initrunner` but explicit initrunner chat ``` ### Send a prompt then continue interactively ```bash # Send a question, then stay in the REPL for follow-ups initrunner chat -p "Explain Python decorators" ``` ### Override provider and model ```bash # Use a specific provider and model initrunner chat --provider anthropic --model claude-sonnet-4-5-20250929 ``` ## Role-Based Chat Load an existing role file with tools, memory, guardrails, and everything else defined in YAML: ```bash initrunner chat role.yaml ``` When a role file is provided, the `--provider`, `--model`, `--tool-profile`, and `--tools` flags are ignored — the role file controls everything. Combine with `-p` to send an initial prompt then continue interactively: ```bash initrunner chat role.yaml -p "Summarize today's news" ``` ## One-Command Bot Mode Launch a Telegram or Discord bot with a single command: ```bash # Telegram bot export TELEGRAM_BOT_TOKEN="your-token" initrunner chat --telegram # Discord bot export DISCORD_BOT_TOKEN="your-token" initrunner chat --discord ``` Or, to persist tokens across sessions, add them to `~/.initrunner/.env`: ```dotenv TELEGRAM_BOT_TOKEN=your-token DISCORD_BOT_TOKEN=your-token ``` Combine with tool flags to give the bot more capabilities: ```bash # Telegram bot with every tool enabled initrunner chat --telegram --tool-profile all # Discord bot with just git and shell tools initrunner chat --discord --tools git --tools shell ``` ### What it creates Bot mode builds an ephemeral role in memory with: - Name: `telegram-bot` or `discord-bot` - Provider and model: auto-detected from environment - Tools: `minimal` profile (datetime + web_reader) by default - Daily token budget: 200,000 - Autonomous mode: enabled (responds to messages without confirmation) ### `chat --telegram` vs `daemon role.yaml` | | `chat --telegram` / `--discord` | `daemon role.yaml` | |---|---|---| | **Config** | Auto-generated in memory | Full YAML with all options | | **Tools** | Tool profile + `--tools` extras | Any tools from the registry | | **Access control** | None — responds to everyone | `allowed_users` / `allowed_roles` | | **Token budget** | 200k daily (hardcoded) | Configurable in guardrails | | **Memory** | On by default (`--no-memory` to disable, `--resume` to continue) | Configurable | | **Use case** | Prototyping, personal use | Production, shared bots | **Recommendation:** Use `chat --telegram` / `--discord` for quick testing. Switch to a `role.yaml` with `initrunner daemon` for anything shared or long-running. ## CLI Options Synopsis: `initrunner chat [role.yaml] [OPTIONS]` | Flag | Description | |------|-------------| | `role_file` | Path to `role.yaml` (positional, optional). Omit for auto-detect mode. | | `--provider TEXT` | Model provider — overrides auto-detection. | | `--model TEXT` | Model name — overrides auto-detection. | | `-p, --prompt TEXT` | Send a prompt then enter REPL (or launch bot with this context). | | `--telegram` | Launch as a Telegram bot daemon. | | `--discord` | Launch as a Discord bot daemon. | | `--tool-profile TEXT` | Tool profile: `none`, `minimal` (default), `all`. | | `--tools TEXT` | Extra tool types to enable (repeatable). See [Extra Tools](#extra-tools). | | `--list-tools` | List available extra tool types and exit. | | `--ingest PATH` | Ingest a directory for RAG search. Chunks, embeds, and indexes the files. | | `--memory / --no-memory` | Enable or disable chat memory (default: enabled). | | `--resume` | Resume the most recent chat session. | | `--audit-db PATH` | Path to audit database. | | `--no-audit` | Disable audit logging. | ## Tool Profiles Tool profiles control which tools are available in auto-detect and bot modes. When a role file is provided, it defines its own tools and the profile is ignored. | Profile | Tools | Notes | |---------|-------|-------| | `none` | *(none)* | Safest — pure text chat, no tool access. | | `minimal` | `datetime`, `web_reader` | Default. Time awareness and web page reading. | | `all` | All tools from [Extra Tools](#extra-tools) table | Includes `shell`, `python`, and `slack` — see Security. Requires env vars for `slack`. | ```bash # Chat with no tools initrunner chat --tool-profile none # Chat with every available tool SLACK_WEBHOOK_URL="https://hooks.slack.com/..." initrunner chat --tool-profile all ``` ## Extra Tools Use `--tools` to add individual tools on top of the selected profile, or use `--tool-profile all` to enable everything at once. This is how you enable outbound integrations (like Slack) without writing a full `role.yaml`. ```bash # Add slack to the default minimal profile SLACK_WEBHOOK_URL="https://hooks.slack.com/..." initrunner chat --telegram --tools slack # Add multiple tools initrunner chat --tools git --tools shell # Combine with a profile initrunner chat --tool-profile all --tools slack ``` Duplicates are ignored — `--tool-profile all --tools search` won't add `search` twice. ### Supported extra tools | Tool | Required env vars | Notes | |------|-------------------|-------| | `datetime` | — | Time awareness (included in `minimal`). | | `web_reader` | — | Fetch and read web pages (included in `minimal`). | | `search` | — | Web search (included in `all`). | | `python` | — | Execute Python code (included in `all`). | | `filesystem` | — | Read-only filesystem access (included in `all`). | | `slack` | `SLACK_WEBHOOK_URL` | Send messages to a Slack channel. | | `git` | — | Read-only git operations in current directory. | | `shell` | — | Execute shell commands. | Run `initrunner chat --list-tools` to see this list from the CLI. ### Fail-fast behavior If a tool requires an environment variable that isn't set, the command exits immediately with an actionable error. This applies to both `--tools` and `--tool-profile all`: ``` Error: Tool 'slack' requires SLACK_WEBHOOK_URL. Export it or add it to your .env file: export SLACK_WEBHOOK_URL=your-value ``` ### Role-file mode When a role file is provided (`initrunner chat role.yaml --tools slack`), the `--tools` flag is ignored with an info message. The role file defines its own tools. ## Document Search (`--ingest`) The `--ingest` flag gives you CLI-driven RAG with no YAML file. Point it at a directory and InitRunner chunks, embeds, and indexes the files, then registers `search_documents()` as a tool. ```bash # Search your docs folder initrunner chat --ingest ./docs/ # Combine with tools initrunner chat --ingest ./docs/ --tool-profile all # Combine with a bot initrunner chat --telegram --ingest ./knowledge-base/ ``` ### How it works 1. InitRunner resolves the path and globs for supported files. 2. Files are chunked (paragraph strategy, 512 chars, 50 overlap). 3. Chunks are embedded using the auto-detected provider. 4. The `search_documents()` tool is registered for the session. ### Supported file types All core formats are supported: `.txt`, `.md`, `.rst`, `.csv`, `.json`, `.html`. Install `initrunner[ingest]` for `.pdf`, `.docx`, and `.xlsx`. ### Re-indexing Each `--ingest` invocation re-indexes the directory. Vectors are stored in a session-scoped database under `~/.initrunner/stores/`. ## Memory in Chat Chat mode has memory enabled by default. The agent remembers facts across turns within a session and can persist them across sessions. ```bash # Default — memory on initrunner chat # Resume the last session initrunner chat --resume # Disable memory entirely initrunner chat --no-memory ``` ### Default behavior When memory is enabled (the default), chat mode creates a lightweight memory store with semantic memory. The agent can use `remember()` and `recall()` to store and retrieve facts. ### `--resume` Loads the most recent chat session for the auto-detected provider. Picks up the conversation where you left off, including any stored memories. ### `--no-memory` Disables all memory for the session. No facts are stored, no sessions are persisted. Each conversation starts fresh. ## Provider Auto-Detection When `--provider` is not specified, InitRunner checks environment variables in this order: | Priority | Provider | Environment Variable | Default Model | |----------|----------|---------------------|---------------| | 1 | anthropic | `ANTHROPIC_API_KEY` | `claude-sonnet-4-5-20250929` | | 2 | openai | `OPENAI_API_KEY` | `gpt-5-mini` | | 3 | google | `GOOGLE_API_KEY` | `gemini-2.0-flash` | | 4 | groq | `GROQ_API_KEY` | `llama-3.3-70b-versatile` | | 5 | mistral | `MISTRAL_API_KEY` | `mistral-large-latest` | | 6 | cohere | `CO_API_KEY` | `command-r-plus` | | 7 | ollama | *(localhost:11434 reachable)* | First available model or `llama3.2` | The first key found wins. Ollama is used as a fallback only when no API keys are set and Ollama is running locally. To override auto-detection: ```bash # Force a specific provider (uses its default model) initrunner chat --provider google # Force both provider and model initrunner chat --provider openai --model gpt-4o ``` Environment variables can also be set in `~/.initrunner/.env` or a `.env` file in the current directory. Running `initrunner setup` writes the provider key there automatically. ## Security - **Tool profiles control agent capabilities.** The `none` profile is safest for untrusted environments. The `minimal` default gives time and web reading. The `all` profile enables every tool including `python`, `shell`, and `slack`. - **`all` profile includes `python` and `shell` = full host access.** Both tools can execute arbitrary code on the host. Never use `all` in public-facing bots without access control. - **`--tools shell` grants shell access.** Like `python`, the `shell` tool allows arbitrary command execution. Only use it in trusted, local contexts. - **`--tools slack` sends messages to a real channel.** The Slack webhook URL is a secret — treat it like a token. Anyone with the URL can post to the channel. - **Bot tokens are secrets.** Store them in environment variables or `.env` files. Never commit tokens to version control. Anyone with the token can impersonate the bot. - **Ephemeral bots respond to everyone.** Bot mode does not set `allowed_users` or `allowed_roles` by default. Every user who can message the bot can use it — and invoke its tools. - **Daily token budget is a cost firewall.** Bot mode defaults to 200,000 tokens/day. For production, tune `daemon_daily_token_budget` in your role's `spec.guardrails` to match expected usage and budget. - **Use `role.yaml` for production bots.** The `chat` shortcuts are designed for prototyping and personal use. Production bots should use a role file with explicit access control, token budgets, and tool configuration. ## Troubleshooting ### No API key found ``` Error: No API key found. Run initrunner setup or set an API key environment variable. ``` No provider was detected. Either export an API key or start Ollama locally: ```bash export ANTHROPIC_API_KEY="sk-..." # or ollama serve ``` You can also add the key to `~/.initrunner/.env` so it persists across sessions: ```dotenv ANTHROPIC_API_KEY=sk-... ``` ### Unknown tool profile ``` Error: Unknown tool profile 'foo'. Use: none, minimal, all ``` The `--tool-profile` value must be one of `none`, `minimal`, or `all`. ### Unknown tool type ``` Error: Unknown tool type 'foo'. Supported: datetime, filesystem, git, python, search, shell, slack, web_reader ``` The `--tools` value must be one of the supported extra tool types. Run `initrunner chat --list-tools` to see the full list. ### Missing required environment variable for tool ``` Error: Tool 'slack' requires SLACK_WEBHOOK_URL. Export it or add it to your .env file: export SLACK_WEBHOOK_URL=your-value ``` Some tools require environment variables. Set the variable before running the command. ### --telegram and --discord are mutually exclusive ``` Error: --telegram and --discord are mutually exclusive. ``` You can only launch one bot platform at a time. To run both, use two separate role files with `initrunner daemon`. ### TELEGRAM_BOT_TOKEN / DISCORD_BOT_TOKEN not set ``` Error: TELEGRAM_BOT_TOKEN not set. Export it or add it to your .env file: export TELEGRAM_BOT_TOKEN=your-bot-token ``` Export the token or add it to `~/.initrunner/.env`: ```bash export TELEGRAM_BOT_TOKEN="your-token-here" ``` Or add it to `~/.initrunner/.env`: ```dotenv TELEGRAM_BOT_TOKEN=your-token-here ``` ### Module not found (telegram / discord) ``` Error: python-telegram-bot is not installed. Install it: pip install initrunner[telegram] ``` Install the platform's optional dependency: ```bash # For Telegram pip install initrunner[telegram] # or uv sync --extra telegram # For Discord pip install initrunner[discord] # or uv sync --extra discord ``` ### Wrong provider auto-detected Auto-detection uses the priority order listed above. If you have multiple API keys set and the wrong provider is picked, override explicitly: ```bash initrunner chat --provider anthropic ``` ## What's Next - [CLI Reference](/docs/cli) — Full command and flag reference - [Discord](/docs/discord) — Full Discord bot setup with role file and access control - [Telegram](/docs/telegram) — Full Telegram bot setup with role file and access control - [Guardrails](/docs/guardrails) — Token budgets, timeouts, and request limits - [Triggers](/docs/triggers) — Cron, file watcher, webhook, and messaging triggers - [Providers](/docs/providers) — Detailed provider setup and options ### Telegram Bot # Telegram Bot Get a Telegram bot agent running in three steps. For the full trigger reference, see [Triggers](/docs/triggers). ## Prerequisites - InitRunner installed (`pip install initrunner` or `uv tool install initrunner`) - An API key for your provider (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, etc.) - The Telegram optional dependency: `uv sync --extra telegram` (or `pip install initrunner[telegram]`) ## Step 1: Create a Bot with BotFather 1. Open Telegram and search for **@BotFather**. 2. Send `/newbot` and follow the prompts to choose a name and username. 3. BotFather replies with a token — copy it. You'll need it in Step 2. ## Step 2: Set Environment Variables ```bash export TELEGRAM_BOT_TOKEN="your-token-here" export OPENAI_API_KEY="your-api-key" # or your provider's key ``` Or, to persist keys across sessions, add them to `~/.initrunner/.env`: ```dotenv TELEGRAM_BOT_TOKEN=your-token-here OPENAI_API_KEY=your-api-key ``` A `.env` file next to your `role.yaml` also works. Running `initrunner setup` writes the provider key there automatically. Existing environment variables always take precedence over `.env` values. ## Step 3: Create a Role and Run Create a `role.yaml`: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: telegram-assistant description: A Telegram bot that responds to messages via long-polling spec: role: | You are a helpful assistant responding to Telegram messages. Keep responses concise and well-formatted for mobile reading. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 triggers: - type: telegram token_env: TELEGRAM_BOT_TOKEN guardrails: max_tokens_per_run: 50000 daemon_daily_token_budget: 200000 ``` Start the daemon: ```bash initrunner daemon role.yaml ``` You should see `Telegram bot started polling` in the logs. ### Quick Alternative To test without creating a role file: ```bash initrunner chat --telegram ``` Auto-detects your provider, launches an ephemeral bot with minimal tools and persistent memory enabled by default. Use `--tool-profile all` for everything, or add individual tools with `--tools`: ```bash # Enable every available tool SLACK_WEBHOOK_URL="https://hooks.slack.com/..." initrunner chat --telegram --tool-profile all # Or add specific extras initrunner chat --telegram --tools git --tools shell # Restrict to specific users by ID (recommended) or username initrunner chat --telegram --allowed-user-ids 123456789 initrunner chat --telegram --allowed-users alice --allowed-users bob # Disable memory if not needed initrunner chat --telegram --no-memory ``` Run `initrunner chat --list-tools` to see all available tool types. For production, use the `role.yaml` approach above for access control and budgets. See [Chat](/docs/chat). ## Testing - Send a plain text message to your bot in Telegram. - Long responses are automatically chunked at 4096-character boundaries. - `/start`, `/help`, and other commands are ignored — only plain text messages are processed. ## Configuration Options All options go under `spec.triggers[].`: | Field | Type | Default | Description | |-------|------|---------|-------------| | `token_env` | `str` | `"TELEGRAM_BOT_TOKEN"` | Environment variable holding the bot token. | | `allowed_users` | `list[str]` | `[]` | Telegram usernames allowed to interact. Empty = allow everyone. | | `allowed_user_ids` | `list[int]` | `[]` | Telegram user IDs allowed to interact. Empty = allow everyone. | | `prompt_template` | `str` | `"{message}"` | Template for the prompt. `{message}` is replaced with the user's text. | Example with restrictions: ```yaml triggers: - type: telegram token_env: TELEGRAM_BOT_TOKEN allowed_users: ["alice", "bob"] allowed_user_ids: [123456789, 987654321] prompt_template: "Telegram user asks: {message}" ``` ## Security and Public Access By default the bot responds to **anyone** who messages it. Lock it down before making it available to others: - **Prefer `allowed_user_ids` over `allowed_users`.** Usernames are mutable — users can change them at any time. User IDs are permanent. Find your ID via [@userinfobot](https://t.me/userinfobot). - **Use `allowed_users`** to restrict access by Telegram username. When either `allowed_users` or `allowed_user_ids` is non-empty, messages from unmatched users are silently ignored. - **Union semantics:** access is granted if the user matches **either** `allowed_users` or `allowed_user_ids`. Both fields can be set together. - **Set `daemon_daily_token_budget`** in guardrails to cap API costs. Without a budget, a public bot can run up unlimited charges. - **Keep the bot token secret.** Anyone with the token can impersonate the bot. Never commit it to version control — use environment variables or a secrets manager. - If the bot has access to tools (filesystem, HTTP, shell, etc.), **restrict to known users only**. An unrestricted bot lets strangers invoke those tools through the bot. ## Troubleshooting ### `ModuleNotFoundError: No module named 'telegram'` The optional dependency is not installed. Run: ```bash uv sync --extra telegram # or pip install initrunner[telegram] ``` ### `Env var TELEGRAM_BOT_TOKEN not set` Export the token before starting the daemon: ```bash export TELEGRAM_BOT_TOKEN="your-token-here" ``` ### Bot ignores messages Only plain text messages are processed. `/start`, `/help`, and other slash commands are filtered out.

For the full trigger reference, see [Triggers](/docs/triggers). ## Prerequisites - InitRunner installed (`pip install initrunner` or `uv tool install initrunner`) - An API key for your provider (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, etc.) - The Discord optional dependency: `uv sync --extra discord` (or `pip install initrunner[discord]`) ## Step 1: Create a Discord Application 1. Go to the [Discord Developer Portal](https://discord.com/developers/applications). 2. Click **New Application**, give it a name, and click **Create**. 3. Go to the **Bot** tab in the left sidebar. 4. Click **Reset Token** and copy the token — you'll need it in Step 3. ## Step 2: Enable Message Content Intent Still on the **Bot** tab: 1. Scroll down to **Privileged Gateway Intents**. 2. Enable **Message Content Intent**. 3. Click **Save Changes**. Without this intent the bot connects but silently receives empty message bodies. ## Step 3: Set Environment Variables ```bash export DISCORD_BOT_TOKEN="your-token-here" export OPENAI_API_KEY="your-api-key" # or your provider's key ``` Or, to persist keys across sessions, add them to `~/.initrunner/.env`: ```dotenv DISCORD_BOT_TOKEN=your-token-here OPENAI_API_KEY=your-api-key ``` A `.env` file next to your `role.yaml` also works. Running `initrunner setup` writes the provider key there automatically. Existing environment variables always take precedence over `.env` values. ## Step 4: Invite the Bot to Your Server 1. Go to the **OAuth2** tab in the Developer Portal. 2. Under **OAuth2 URL Generator**, select the `bot` scope. 3. Under **Bot Permissions**, select: - **Send Messages** - **Read Message History** 4. Copy the generated URL and open it in your browser. 5. Select the server you want to add the bot to and click **Authorize**. ## Step 5: Create a Role and Run Create a `role.yaml`: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: discord-assistant description: A Discord bot that responds to DMs and @mentions spec: role: | You are a helpful assistant responding to Discord messages. Keep responses concise. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 triggers: - type: discord token_env: DISCORD_BOT_TOKEN guardrails: max_tokens_per_run: 50000 daemon_daily_token_budget: 200000 ``` Start the daemon: ```bash initrunner daemon role.yaml ``` You should see `Discord bot connected` in the logs. ### Quick Alternative To test without creating a role file: ```bash initrunner chat --discord ``` Auto-detects your provider, launches an ephemeral bot with minimal tools and persistent memory enabled by default. Use `--tool-profile all` for everything, or add individual tools with `--tools`: ```bash # Enable every available tool SLACK_WEBHOOK_URL="https://hooks.slack.com/..." initrunner chat --discord --tool-profile all # Or add specific extras initrunner chat --discord --tools git --tools shell # Restrict to specific users by ID (works in DMs and guild channels) initrunner chat --discord --allowed-user-ids 111222333444555666 # Disable memory if not needed initrunner chat --discord --no-memory ``` Run `initrunner chat --list-tools` to see all available tool types. For production, use the `role.yaml` approach above for access control and budgets. See [Chat](/docs/chat). ## Testing - **@mention** — In a server channel, type `@YourBot what time is it?` - **DM** — Open a direct message with the bot and send any text. - **Long responses** — Responses over 2000 characters are automatically chunked at newline boundaries. ## Configuration Options All options go under `spec.triggers[].`: | Field | Type | Default | Description | |-------|------|---------|-------------| | `token_env` | `str` | `"DISCORD_BOT_TOKEN"` | Environment variable holding the bot token. | | `channel_ids` | `list[str]` | `[]` | Channel IDs to respond in. Empty = all channels. Does not affect DMs. | | `allowed_roles` | `list[str]` | `[]` | Server role names required to interact. Empty = allow everyone. DMs are denied when only roles are configured. | | `allowed_user_ids` | `list[str]` | `[]` | Discord user IDs allowed to interact. Works in both guild channels and DMs. | | `prompt_template` | `str` | `"{message}"` | Template for the prompt. `{message}` is replaced with the user's text. | Example with restrictions: ```yaml triggers: - type: discord token_env: DISCORD_BOT_TOKEN channel_ids: ["1234567890"] allowed_roles: ["Bot-User", "Admin"] allowed_user_ids: ["111222333444555666"] prompt_template: "Discord user asks: {message}" ``` ## Security and Public Access By default the bot responds to **anyone** who can DM it or @mention it in a shared server. This means every member of every server the bot is in can use it. Lock it down before making it available to others: - **Use `allowed_user_ids`** for the most reliable access control. Unlike `allowed_roles`, user IDs work in DMs. When both `allowed_roles` and `allowed_user_ids` are set, a user ID match grants DM access. To find a user ID: enable Developer Mode (Settings > Advanced), right-click a user > Copy User ID. - **Use `allowed_roles`** to restrict access to specific server roles. When only roles are configured, DMs are automatically denied (DMs have no role context). - **Use `channel_ids`** to confine the bot to specific guild channels. `channel_ids` restricts guild channels only — DMs are not affected. - **Set `daemon_daily_token_budget`** in guardrails to cap API costs. Without a budget, a public bot can run up unlimited charges. - **Keep the bot token secret.** Anyone with the token can impersonate the bot. Never commit it to version control — use environment variables or a secrets manager. - **Limit server exposure.** If the bot has access to tools (filesystem, HTTP, shell, etc.), keep it in a private server only. A public server lets strangers invoke those tools through the bot. ## Troubleshooting ### Bot connects but never responds The **Message Content Intent** is not enabled. Go to the Developer Portal > Bot > Privileged Gateway Intents and enable it (see Step 2). ### `ModuleNotFoundError: No module named 'discord'` The optional dependency is not installed. Run: ```bash uv sync --extra discord # or pip install initrunner[discord] ``` ### `Env var DISCORD_BOT_TOKEN not set` Export the token before starting the daemon: ```bash export DISCORD_BOT_TOKEN="your-token-here" ``` ### Bot responds in wrong channels Set `channel_ids` to a list of channel ID strings. To get a channel ID, enable Developer Mode in Discord (Settings > Advanced > Developer Mode), then right-click a channel and select **Copy Channel ID**. ### Role Creation # Role Creation A role file (`role.yaml`) defines your agent — its model, system prompt, tools, guardrails, and everything else. InitRunner gives you multiple ways to create one depending on how much control you want. ## Quick Comparison | Method | Command | Best for | |--------|---------|----------| | **AI Generate** | `initrunner create "..."` | Fastest start — describe what you want in plain English | | **Interactive Wizard** | `initrunner init -i` | Guided setup with tool configuration prompts | | **Template** | `initrunner init --template ` | Non-interactive scaffolding from a known pattern | | **Copy Example** | `initrunner examples copy ` | Learning from complete, runnable examples | | **Dashboard** | `/roles/new` in the web UI | Visual form builder or AI generation in the browser | | **Manual YAML** | Create `role.yaml` by hand | Full control over every field | ## AI Generation Generate a complete role from a natural language description: ```bash initrunner create "A code review assistant that reads git diffs and suggests improvements" ``` This creates a `role.yaml` in the current directory. Review it, tweak if needed, and run it. ### Flags | Flag | Description | |------|-------------| | `--provider TEXT` | Model provider for generation (auto-detected if omitted) | | `--output PATH` | Output file path (default: `role.yaml`) | | `--name TEXT` | Agent name (auto-derived from description if omitted) | | `--model TEXT` | Model name for the generated role (e.g. `gpt-4o`, `claude-sonnet-4-5-20250929`) | | `--no-confirm` | Skip the YAML preview and write immediately | ### How It Works 1. Builds a dynamic schema reference by introspecting Pydantic models. This includes all tool types from the registry, trigger types, sink types, and every configurable field with defaults. 2. Sends the description plus schema reference to the configured LLM. 3. Validates the returned YAML against `RoleDefinition`. 4. If validation fails, retries once by sending the error back to the LLM for correction. ### Provider Auto-Detection When `--provider` is omitted, InitRunner checks for available API keys in the environment (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, etc.) and uses the first provider found. Falls back to `openai`. ### Example ```bash initrunner create "A Python tutor that executes code examples and explains errors" \ --provider anthropic \ --name python-tutor \ --output tutor-role.yaml ``` ## Interactive Wizard Launch the guided wizard: ```bash initrunner init -i ``` The wizard walks through each section of a role definition, building a complete `role.yaml` step by step. ### Wizard Flow 1. **Agent name** — lowercase with hyphens (e.g. `my-agent`) 2. **Description** — optional free-text 3. **Provider** — choose from `openai`, `anthropic`, `google`, `groq`, `mistral`, `cohere`, `ollama` 4. **Model** — choose from a curated list for the selected provider, or type a custom model name 5. **Base template** — pre-populates system prompt, tools, and features (see table below) 6. **Tool selection** — pick tools by number or name, then configure each one 7. **Memory** — enable/disable long-term memory 8. **Ingestion** — enable/disable RAG with source glob and chunking config 9. **Output file** — path to write (default: `role.yaml`) ### Templates | Template | Description | |----------|-------------| | `basic` | Simple assistant | | `rag` | Answers from your documents | | `memory` | Remembers across sessions | | `daemon` | Runs on schedule / watches files | | `api` | Declarative REST API tools | | `blank` | Just the essentials, add everything yourself | ### Available Tools | Tool | Description | Key config fields | |------|-------------|-------------------| | `filesystem` | Read/write files | `root_path`, `read_only` | | `git` | Git operations | — | | `python` | Execute Python code | — | | `shell` | Run shell commands | `require_confirmation`, `timeout_seconds` | | `http` | HTTP requests | — | | `web_reader` | Fetch web pages | — | | `sql` | Query SQLite databases | — | | `datetime` | Date/time utilities | — | | `mcp` | MCP server integration | — | | `slack` | Send Slack messages | — | Each selected tool prompts for its key configuration fields. For details on all tools, see [Tools](/docs/tools). ### Anthropic Embedding Warning When the wizard detects that `anthropic` is selected as the provider **and** memory or ingestion is enabled, it displays a warning: > **Warning:** Anthropic does not provide an embeddings API. RAG and memory features require `OPENAI_API_KEY` for embeddings. The embedding provider can be overridden via `spec.ingest.embeddings` or `spec.memory.embeddings` in the generated role file. ## Templates Scaffold from a built-in template without interactive prompts: ```bash initrunner init --name my-agent --template basic ``` Available templates: `basic`, `rag`, `daemon`, `memory`, `ollama`, `tool`, `api`, `skill`. ```bash # RAG agent with document search initrunner init --name doc-search --template rag # Background daemon that runs on a schedule initrunner init --name watcher --template daemon # Agent with long-term memory initrunner init --name assistant --template memory ``` ## Copy an Example Browse and copy community examples: ```bash initrunner examples list # browse available examples initrunner examples show file-reader # preview the YAML initrunner examples copy file-reader # copy files to current directory ``` See [Examples](/docs/examples) for the full catalog. ## Dashboard — Create Role The web dashboard at `/roles/new` offers two tabs for role creation. ### Form Builder Tab A structured form with fields for: - Name, description - Provider, model (dropdown with curated per-provider options and custom input) - System prompt - Tool checkboxes - Memory and ingestion toggles - Live YAML preview that updates as you fill in the form Submitting the form calls `POST /api/roles` with the generated YAML. ### AI Generate Tab 1. Enter a natural language description 2. Click **Generate** to produce a `role.yaml` via AI 3. Review and edit the generated YAML 4. Click **Save** to persist This calls `POST /api/roles/generate` to get the YAML, then `POST /api/roles` to save. ### API Endpoints | Method | Endpoint | Description | |--------|----------|-------------| | `POST` | `/api/roles` | Create a new role from YAML content | | `POST` | `/api/roles/generate` | Generate YAML from a natural language description | `POST /api/roles` returns `409` if a role file with the same name already exists. ## Manual YAML For full control, create a `role.yaml` by hand. Every role file has four top-level keys: `apiVersion`, `kind`, `metadata`, and `spec`. See [Configuration](/docs/configuration) for the full schema reference. ### Minimum Viable Role The smallest valid role needs metadata, a system prompt, and a model: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: my-agent description: A helpful assistant spec: role: | You are a helpful assistant. model: provider: openai name: gpt-4o-mini ``` ### Adding Tools Add a `tools` list under `spec`: ```yaml spec: tools: - type: filesystem root_path: . read_only: true - type: shell require_confirmation: true timeout_seconds: 30 ``` ### Adding Memory Add a `memory` section so the agent remembers across sessions: ```yaml spec: memory: max_sessions: 10 max_resume_messages: 20 semantic: max_memories: 500 ``` Run with `--resume` to pick up where you left off. See [Memory](/docs/memory) for details. ### Adding Ingestion / RAG Add an `ingest` section to let the agent search your documents: ```yaml spec: ingest: sources: - "./**/*.md" chunking: strategy: paragraph chunk_size: 512 chunk_overlap: 50 ``` Run `initrunner ingest role.yaml` to index, then ask questions about your docs. See [Ingestion](/docs/ingestion) for details. ### Adding Triggers and Sinks Triggers automate when the agent runs. Sinks control where output goes: ```yaml spec: triggers: - type: cron schedule: "*/30 * * * *" - type: watch paths: ["./src/**/*.py"] sinks: - type: file path: ./reports/output.md - type: slack channel: "#alerts" ``` See [Triggers](/docs/triggers) and [Sinks](/docs/sinks) for all options. ### Adding Guardrails Set resource limits to keep the agent safe: ```yaml spec: guardrails: max_tokens_per_run: 10000 max_tool_calls: 10 timeout_seconds: 60 max_request_limit: 10 ``` See [Guardrails](/docs/guardrails) for the full reference. ## Editing Existing Roles ### Dashboard YAML Editor The role detail page (`/roles/{role_id}`) includes an editable YAML tab with **Save** and **Reset** buttons. - **Save** calls `PUT /api/roles/{role_id}` with the updated YAML content - Creates a `.bak` backup of the existing file before overwriting - Validates the YAML against `RoleDefinition` before writing ### CLI Editing Open the role file in your editor, make changes, then validate: ```bash $EDITOR role.yaml initrunner validate role.yaml ``` ## Validation Check your YAML before running: ```bash initrunner validate role.yaml ``` This parses the file and validates it against the `RoleDefinition` schema. Errors are printed with field paths so you can fix them quickly. ## Security Notes - **Name validation**: `metadata.name` must match `^[a-z0-9][a-z0-9-]*[a-z0-9]$` - **Directory restrictions**: API writes are restricted to configured role directories; path traversal (`..`) is rejected - **Overwrite protection**: `POST /api/roles` returns `409` if the file exists; updates via `PUT` create a `.bak` backup before overwriting - **Validation before write**: YAML is parsed and validated against `RoleDefinition` before being written to disk ## Next Steps - [Configuration](/docs/configuration) — Full YAML schema reference - [Tools](/docs/tools) — All available tools and their configuration - [Examples](/docs/examples) — Complete, runnable agents for common use cases - [Quickstart](/docs/quickstart) — Get your first agent running in under five minutes ### RAG in 5 Minutes # RAG in 5 Minutes Get a document-search agent up and running in three commands. > **Before you start:** `initrunner ingest` needs an embedding model. The default is OpenAI `text-embedding-3-small` — set `OPENAI_API_KEY` to use it, or set `embeddings.provider` to switch providers ([Google, Ollama, and more](/docs/providers)). No API keys? [Jump to fully local setup.](#fully-local--no-api-keys) ## The 3-Command Flow ```bash initrunner setup --template rag # scaffold a RAG-ready role file initrunner ingest role.yaml # embed and index your documents initrunner run role.yaml # chat with your knowledge base ``` ### What each command does **`initrunner setup --template rag`** Scaffolds a role YAML pre-configured with `spec.ingest` pointing at a `./docs/` directory, paragraph chunking, and `search_documents` usage instructions in the system prompt. A `docs/` folder with a sample markdown file is created alongside the role file. The scaffolded role file includes this embedding config by default: ```yaml spec: ingest: sources: - "./docs/**/*.md" embeddings: provider: openai model: text-embedding-3-small # api_key_env: OPENAI_API_KEY # optional: override which env var holds the key ``` Change `provider` and `model` to switch embedding backends. See [Providers](/docs/providers) for all options. After the setup wizard finishes it prints a reminder: ``` Next step: add your documents to ./docs/ then run: initrunner ingest role.yaml ``` **`initrunner ingest role.yaml`** Reads every file matched by `spec.ingest.sources`, splits the text into chunks, generates embeddings, and stores everything in a local SQLite vector database (`~/.initrunner/stores/.db`). Re-running is safe — existing chunks are replaced. **`initrunner run role.yaml`** Starts the agent. The `search_documents` tool is auto-registered. Ask any question and the agent will search your indexed documents before answering, citing the source files it used. ## Embedding API Key The embedding key is read from an environment variable. The default depends on your provider: | Provider | Default env var | Notes | |----------|-----------------|-------| | `openai` | `OPENAI_API_KEY` | | | `anthropic` | `OPENAI_API_KEY` | Anthropic has no embeddings API — falls back to OpenAI by default; set `embeddings.provider` to switch | | `google` | `GOOGLE_API_KEY` | | | `ollama` | *(none)* | Runs locally | **Anthropic users:** Anthropic has no embeddings API. The default fallback is OpenAI — set `OPENAI_API_KEY` (in your environment or `~/.initrunner/.env`) if keeping that default. To avoid needing an OpenAI key, set `embeddings.provider: google` or `embeddings.provider: ollama` instead. **Override the key name** — if your key is stored under a different env var name, set `api_key_env` in the embedding config: ```yaml spec: ingest: embeddings: provider: openai model: text-embedding-3-small api_key_env: MY_EMBED_KEY # read from MY_EMBED_KEY instead of OPENAI_API_KEY ``` **Diagnose key issues** with the doctor command: ```bash initrunner doctor ``` The Embedding Providers section shows which keys are set and which are missing. ## Fully Local — No API Keys Swap both the LLM and the embedding model to Ollama for a completely local setup: ```yaml spec: model: provider: ollama name: llama3.2 ingest: sources: - "./docs/**/*.md" embeddings: provider: ollama model: nomic-embed-text ``` Then run the same three commands — no API keys required. ## Next Steps - [Ingestion reference](/docs/ingestion) — chunking strategies, embedding models, supported file formats - [RAG Patterns & Guide](/docs/rag-guide) — common patterns, embedding model comparison, fully local RAG ### Memory in 5 Minutes # Memory in 5 Minutes Give any agent persistent memory in three commands — facts it remembers across sessions, episodes it can look back on, and procedures it applies automatically. > **Before you start:** Memory needs an embedding model. The default is OpenAI `text-embedding-3-small` — set `OPENAI_API_KEY` to use it, or set `embeddings.provider` to switch providers ([Google, Ollama, and more](/docs/providers)). No API keys? [Jump to fully local setup.](#fully-local--no-api-keys) ## The 3-Command Flow ```bash initrunner init --name assistant --template memory # scaffold a memory-ready role file initrunner run role.yaml -i # chat — the agent can now remember things initrunner run role.yaml -i --resume # pick up exactly where you left off ``` ### What each command does **`initrunner init --name assistant --template memory`** Scaffolds a role YAML pre-configured with `spec.memory` defaults and a system prompt that instructs the agent to use `remember()`, `recall()`, and `learn_procedure()`. The generated file looks like this: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: assistant spec: role: | You are a helpful assistant with long-term memory. Use remember() to save important facts. Use recall() to search your memories before answering. Use learn_procedure() to record useful patterns. model: provider: openai name: gpt-4o-mini memory: max_sessions: 10 max_resume_messages: 20 embeddings: provider: openai model: text-embedding-3-small # api_key_env: OPENAI_API_KEY # optional: override which env var holds the key semantic: max_memories: 1000 episodic: max_episodes: 500 procedural: max_procedures: 100 consolidation: enabled: true interval: after_session ``` Change `provider` and `model` under `spec.model` to switch LLM backends. See [Providers](/docs/providers) for all options. Change `provider` and `model` under `memory.embeddings` to switch embedding backends. **`initrunner run role.yaml -i`** Starts the agent in interactive mode. The agent has three memory tools available automatically: - **Semantic** — `remember` / `recall`: store and search arbitrary facts by meaning - **Episodic** — `record_episode`: log experiences; auto-captured in autonomous and daemon modes - **Procedural** — `learn_procedure`: save reusable rules that are auto-injected into the system prompt on future sessions Every session is saved to `~/.initrunner/memory//`. Re-running without `--resume` starts a fresh context window but long-term memories persist. **`initrunner run role.yaml -i --resume`** Reloads the previous session's messages (up to `max_resume_messages: 20` by default) so the conversation continues exactly where it left off. Semantic, episodic, and procedural memories are always available regardless of whether you resume. ## Inspect and Manage Memory ```bash initrunner memory list role.yaml # show all stored memories initrunner memory list role.yaml --type semantic # filter by memory type initrunner memory consolidate role.yaml # extract facts from episodes initrunner memory export role.yaml -o memories.json # export to JSON initrunner memory clear role.yaml # wipe all memory for this agent ``` ## Embedding API Key The embedding key is read from an environment variable. The default depends on your provider: | Provider | Default env var | Notes | |----------|-----------------|-------| | `openai` | `OPENAI_API_KEY` | | | `anthropic` | `OPENAI_API_KEY` | Anthropic has no embeddings API — falls back to OpenAI by default; set `embeddings.provider` to switch | | `google` | `GOOGLE_API_KEY` | | | `ollama` | *(none)* | Runs locally | **Anthropic users:** Anthropic has no embeddings API. The default fallback is OpenAI — set `OPENAI_API_KEY` (in your environment or `~/.initrunner/.env`) if keeping that default. To avoid needing an OpenAI key, set `embeddings.provider: google` or `embeddings.provider: ollama` instead. **Override the key name** — if your key is stored under a different env var name, set `api_key_env` in the embedding config: ```yaml spec: memory: embeddings: provider: openai # api_key_env: OPENAI_API_KEY # optional override ``` **Diagnose key issues** with the doctor command: ```bash initrunner doctor ``` The Embedding Providers section shows which keys are set and which are missing. ## Fully Local — No API Keys Swap both the LLM and the embedding model to Ollama for a completely local setup: ```yaml spec: model: provider: ollama name: llama3.2 memory: embeddings: provider: ollama model: nomic-embed-text ``` Then run the same three commands — no API keys required. ## Next Steps - [Memory reference](/docs/memory) — full configuration options, memory types, consolidation, and storage details - [Providers](/docs/providers) — all supported LLM and embedding backends - [Compose](/docs/compose) — share a memory store across multiple agents ### Setup Wizard # Setup Wizard The `initrunner setup` command is a guided, intent-driven wizard that configures your model provider, API key, and first agent role in one step. It detects existing configuration, installs missing SDKs, validates API keys, and creates a ready-to-run `role.yaml` plus a `~/.initrunner/chat.yaml` for `initrunner chat`. ## Quick Start ```bash # Interactive setup (prompts for intent, provider, key, tools) initrunner setup # Non-interactive with all options specified initrunner setup --provider openai --model gpt-4o --intent chatbot --name my-agent --skip-test -y # RAG agent with knowledge base initrunner setup --intent knowledge --provider openai --skip-test -y # Telegram bot initrunner setup --intent telegram-bot --provider anthropic --skip-test -y # Browse and copy a bundled example initrunner setup --intent from-example -y # Local Ollama setup (no API key needed) initrunner setup --provider ollama --intent chatbot -y # Skip the connectivity test initrunner setup --skip-test ``` ## Options Reference | Flag | Type | Default | Description | |------|------|---------|-------------| | `--provider` | `str` | *(interactive)* | Provider name. Skips the interactive selection prompt. | | `--name` | `str` | `my-agent` | Agent name used in the generated role YAML. | | `--intent` | `str` | *(interactive)* | What to build: `chatbot`, `knowledge`, `memory`, `telegram-bot`, `discord-bot`, `api-agent`, `daemon`, or `from-example`. | | `--template` | `str` | — | **Deprecated.** Maps to `--intent` internally (`rag` → `knowledge`, others pass through). | | `--model` | `str` | *(interactive)* | Model name. Skips the interactive model selection prompt. | | `--skip-test` | `bool` | `false` | Skip the connectivity test after setup. | | `--output` | `Path` | `role.yaml` | Output path for the generated role file. | | `-y, --accept-risks` | `bool` | `false` | Accept security disclaimer without prompting. | | `--interfaces` | `str` | *(interactive)* | Install interfaces: `tui`, `dashboard`, `both`, or `skip`. | | `--skip-chat-yaml` | `bool` | `false` | Skip `chat.yaml` generation. | ## Supported Providers | Provider | Env Var | Install Extra | Default Model | |----------|---------|---------------|---------------| | `openai` | `OPENAI_API_KEY` | *(included in core)* | `gpt-5-mini` | | `anthropic` | `ANTHROPIC_API_KEY` | `initrunner[anthropic]` | `claude-sonnet-4-5-20250929` | | `google` | `GOOGLE_API_KEY` | `initrunner[google]` | `gemini-2.0-flash` | | `groq` | `GROQ_API_KEY` | `initrunner[groq]` | `llama-3.3-70b-versatile` | | `mistral` | `MISTRAL_API_KEY` | `initrunner[mistral]` | `mistral-large-latest` | | `cohere` | `CO_API_KEY` | `initrunner[all-models]` | `command-r-plus` | | `bedrock` | `AWS_ACCESS_KEY_ID` | `initrunner[all-models]` | `us.anthropic.claude-sonnet-4-20250514-v1:0` | | `xai` | `XAI_API_KEY` | *(uses openai SDK)* | `grok-3` | | `ollama` | *(none)* | *(included in core)* | `llama3.2` | ## How It Works The setup wizard runs through thirteen steps: ### 1. Already-Configured Detection The wizard checks whether any known provider API key is already set, looking in two places: 1. **Environment variables** — checks each provider's env var (e.g. `OPENAI_API_KEY`). 2. **Global `.env` file** — reads `~/.initrunner/.env` via `dotenv_values()`. If a key is found, the wizard reports which variable was detected and uses that provider as the default. ### 2. Intent Selection The first interactive question is "What do you want to build?": | # | Intent | Description | |---|--------|-------------| | 1 | `chatbot` | Conversational AI assistant | | 2 | `knowledge` | Answer questions from your documents (RAG) | | 3 | `memory` | Assistant that remembers across conversations | | 4 | `telegram-bot` | Telegram bot powered by AI | | 5 | `discord-bot` | Discord bot powered by AI | | 6 | `api-agent` | Agent with REST API tool access | | 7 | `daemon` | Runs on a schedule or watches for changes | | 8 | `from-example` | Browse and copy a bundled example | The intent determines which subsequent steps are shown, which tools are pre-selected, and what role YAML template is generated. ### 3. Provider Selection When `--provider` is not passed, an interactive prompt lists all 9 supported providers. When `--provider` is passed, the value is validated against the supported list. Unknown providers cause an immediate error. ### 4. SDK Check + Auto-Install For **Ollama**, the wizard checks that the server is running and queries for available models. For **Bedrock**, the wizard checks for `boto3` and provides guidance on AWS CLI configuration. For all other providers, the wizard checks whether the provider SDK is importable and offers to install it automatically. ### 5. API Key / Credentials Entry Skipped for Ollama (no API key required). For Bedrock, prompts for AWS region. For other providers: 1. Checks for an existing key in the environment, then in `~/.initrunner/.env`. 2. If found, asks whether to keep it. If not found, prompts for entry (masked input). 3. For OpenAI and Anthropic, validates the key with a lightweight API call. 4. Saves the key to `~/.initrunner/.env` with `0600` permissions. ### 6. Model Selection After the API key is configured, the wizard prompts for a model from a curated list. ### 7. Embedding Config (Conditional) When `intent=knowledge` or `intent=memory` **and** the provider doesn't offer an embeddings API (Anthropic, Groq, Cohere, Bedrock, xAI, Ollama), the wizard warns the user and optionally prompts for an `OPENAI_API_KEY` for embeddings. ### 8. Tool Selection + Configure A numbered tool menu is shown with intent-specific defaults pre-marked with `*`. Users pick tools by comma-separated numbers or press Enter for defaults. After selection, per-tool config prompts are shown (e.g., `filesystem` asks for `root_path` and `read_only`). ### 9. Intent-Specific Config - **knowledge**: Prompts for document sources glob (default: `./docs/**/*.md`) - **telegram-bot**: Prompts for `TELEGRAM_BOT_TOKEN` - **discord-bot**: Prompts for `DISCORD_BOT_TOKEN` - **daemon**: Prompts for trigger type (file_watch or cron) and schedule/paths ### 10. Interface Installation Optional installation of the TUI (Textual) and/or web dashboard (FastAPI). ### 11. Role + Chat YAML Generation Generates `role.yaml` at the `--output` path and `~/.initrunner/chat.yaml` for `initrunner chat`. Use `--skip-chat-yaml` to skip chat.yaml generation. ### 12. Post-Generation Actions - **knowledge**: Offers to run `initrunner ingest` immediately - **All intents**: Connectivity test (skippable with `--skip-test`) ### 13. Summary + Next Steps A summary panel shows the configured intent, provider, model, and file paths. Next-step commands are tailored to the chosen intent. ## "from-example" Flow When selecting intent 8 (`from-example`), the wizard enters a separate flow: 1. Displays a numbered table of bundled examples (roles, compose files, skills) 2. User selects an example by number or name 3. Example files are copied to the current directory 4. **No provider/key/model/role-generation steps** — the example includes everything 5. Summary shows copied files and next steps (validate, run) ## Intents | Intent | Template Key | Description | |--------|-------------|-------------| | `chatbot` | `basic` | Minimal assistant with guardrails. Pre-selects datetime + web_reader tools. | | `knowledge` | `rag` | Knowledge assistant with `ingest` config and `search_documents` tool. Prompts for document sources. | | `memory` | `memory` | Assistant with `memory` config. Auto-registers `remember()`, `recall()`, and `list_memories()` tools. | | `telegram-bot` | `telegram` | Telegram bot with telegram trigger. Prompts for bot token. | | `discord-bot` | `discord` | Discord bot with discord trigger. Prompts for bot token. | | `api-agent` | `api` | Agent with declarative REST API tools. Pre-selects http + datetime tools. | | `daemon` | `daemon` | Event-driven agent with triggers. Prompts for trigger type and schedule. | | `from-example` | — | Browse and copy bundled examples. Separate flow. | All generated roles include guardrails (`max_tokens_per_run`, `max_tool_calls`, `timeout_seconds`, `max_request_limit`) and use the default model for the selected provider. ## Non-Interactive Usage For CI, automation, or scripting, pass all options as flags to skip all prompts: ```bash # Fully non-interactive OpenAI chatbot export OPENAI_API_KEY="sk-..." initrunner setup --provider openai --model gpt-4o --intent chatbot --name my-agent --skip-test --interfaces skip -y # Knowledge agent with Ollama initrunner setup --provider ollama --model llama3.2 --intent knowledge --skip-test --interfaces skip -y # Skip chat.yaml generation initrunner setup --provider openai --intent chatbot --skip-test --skip-chat-yaml --interfaces skip -y ``` The wizard still requires the API key to be available either in the environment or in `~/.initrunner/.env`. If no key is found and no TTY is available, the prompt will fail. ## Backward Compatibility The `--template` flag is still accepted but deprecated. It maps to `--intent` internally: | `--template` | `--intent` | |---|---| | `chatbot` | `chatbot` | | `rag` | `knowledge` | | `memory` | `memory` | | `daemon` | `daemon` | A deprecation hint is printed when `--template` is used. ## Troubleshooting ### Unknown provider ``` Error: Unknown provider 'foo'. Choose from: openai, anthropic, google, groq, mistral, cohere, bedrock, xai, ollama ``` The `--provider` value must be one of the supported providers listed above. ### Unknown intent ``` Error: Unknown intent 'foo'. Choose from: chatbot, knowledge, memory, telegram-bot, discord-bot, api-agent, daemon, from-example ``` ### SDK installation failed ``` Warning: Could not install initrunner[anthropic]: ... Install manually: uv pip install initrunner[anthropic] ``` The automatic SDK installation failed. Install the provider extra manually using the printed command, then re-run setup. ### Embedding warning ``` Warning: anthropic does not provide an embeddings API. RAG and memory features require OPENAI_API_KEY for embeddings. ``` This appears when using a provider without embeddings support with the `knowledge` or `memory` intent. Set `OPENAI_API_KEY` for embeddings, or configure a custom embedding provider in your role.yaml. ### API key validation failed ``` Warning: API key validation failed. ``` The API key could not be verified. This can happen if the key is invalid or expired, the provider API is temporarily unreachable, or a proxy/firewall is blocking the request. Re-enter the key when prompted, or continue and troubleshoot later. ### Could not write .env file ``` Warning: Could not write ~/.initrunner/.env: [Errno 13] Permission denied Set it manually: export OPENAI_API_KEY=sk-... ``` The wizard could not write the API key to the global `.env` file. Set the environment variable manually in your shell profile instead. ### Test run failed ``` Warning: Test run failed: ... Setup is still complete -- check your configuration and try again. ``` The connectivity test failed but setup is still complete. Common causes: incorrect API key, missing provider SDK, Ollama server not running, or network issues. Run `initrunner run role.yaml -p "hello"` manually to debug. ### Output file already exists ``` role.yaml already exists, skipping role creation. ``` The wizard does not overwrite existing role files. Use `--output` to specify a different path, or delete the existing file first. ### Examples # Examples InitRunner ships with 25+ ready-to-run examples across four categories — **single agents**, **teams**, **compose pipelines**, and **reusable skills**. You can discover and clone them straight from the CLI, or browse the detailed walkthroughs below to understand how each one works. ## Browse and Copy from the CLI The fastest way to get started is the built-in examples workflow: 1. **List every example** to see what's available: ```bash initrunner examples list ``` 2. **Show an example** before copying — preview its YAML with syntax highlighting: ```bash initrunner examples show code-reviewer ``` 3. **Copy it** into your current directory: ```bash initrunner examples copy code-reviewer ``` 4. **Run it:** ```bash initrunner run code-reviewer.yaml -p "Review the last commit" ``` > **Tip:** The walkthroughs below explain every field in detail. If you already know what you need, skip ahead to the [Full Example Catalog](#full-example-catalog) for a complete list of available examples. ## Detailed Walkthroughs The following examples are explained section by section so you can understand the patterns and adapt them to your own agents. ### Code Reviewer A read-only code review agent that uses git and filesystem tools to examine changes and produce structured reviews. ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: code-reviewer description: An experienced code review agent tags: - engineering - review spec: role: | You are an experienced senior software engineer performing code reviews. When reviewing code: 1. Start with git_list_files to understand the project structure 2. Use git_changed_files to identify what was modified 3. Use git_diff with specific file paths to examine changes 4. Use git_log to understand the commit history and context 5. Read relevant source files to understand the surrounding code 6. Use git_blame on suspicious lines to understand their history Review guidelines: - Focus on correctness, readability, and maintainability - Identify potential bugs, security issues, and performance problems - Suggest specific improvements with code examples - Be constructive and explain the reasoning behind each suggestion - Prioritize issues by severity: critical > major > minor > style If a diff is truncated, narrow your search by passing a specific file path to git_diff. Format your review as a structured list of findings, each with: - Severity level - Location (file/line if applicable) - Description of the issue - Suggested fix model: provider: openai name: gpt-4o-mini temperature: 0.1 max_tokens: 4096 tools: - type: git repo_path: . read_only: true - type: filesystem root_path: . read_only: true guardrails: max_tokens_per_run: 50000 max_tool_calls: 30 timeout_seconds: 300 max_request_limit: 50 ``` ```bash initrunner run code-reviewer.yaml -p "Review the last commit" ``` > **What to notice:** Two read-only tools (`git` + `filesystem`) give the agent everything it needs to navigate a codebase. The low temperature (0.1) keeps reviews consistent, and the structured role prompt produces predictable output formatting. ### Data Analyst A multi-tool agent that queries SQLite databases, runs Python analysis, and writes output files. ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: data-analyst description: Queries a SQLite database and runs Python analysis tags: - example - sql - python - analytics spec: role: | You are a data analyst with access to a SQLite database and a Python execution environment. Help the user explore data, answer questions, and produce reports. Workflow: 1. Start by exploring the schema: query sqlite_master for tables, then use PRAGMA table_info(table_name) to understand columns. 2. Write SQL queries to answer the user's questions. Use aggregate functions (COUNT, SUM, AVG, GROUP BY) for summaries. 3. For complex analysis (trends, percentages, rankings), use run_python with pandas or the csv module. 4. Write reports and results to the ./output/ directory using write_file. Guidelines: - Always explore the schema before writing queries - Use LIMIT when exploring large tables - Explain your SQL logic to the user - Format numbers with appropriate precision (2 decimal places for currency) - When using Python, prefer the standard library (csv, statistics) if pandas is not available model: provider: openai name: gpt-4o-mini temperature: 0.1 max_tokens: 4096 tools: - type: sql database: ./sample.db read_only: true max_rows: 100 - type: python working_dir: . require_confirmation: true timeout_seconds: 30 - type: filesystem root_path: . read_only: false allowed_extensions: - .txt - .md - .csv guardrails: max_tokens_per_run: 50000 max_tool_calls: 30 timeout_seconds: 300 max_request_limit: 50 ``` ```bash initrunner run data-analyst.yaml -i -p "What were the top 5 products by revenue last quarter?" ``` > **What to notice:** Three tools working together — `sql` for queries, `python` for complex analysis, and `filesystem` for writing reports. The `require_confirmation: true` on the Python tool adds a safety gate before executing code. ### RAG Knowledge Base A documentation assistant with document ingestion, paragraph chunking, and source citation. ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: rag-agent description: Knowledge base Q&A agent with document ingestion tags: - example - rag - knowledge-base spec: role: | You are a helpful documentation assistant for AcmeDB. You answer user questions using the ingested knowledge base. Rules: - ALWAYS call search_documents before answering a question - Base your answers only on information found in the documents - Cite the source document for each claim (e.g., "Per the Getting Started guide, ...") - If search_documents returns no relevant results, say so honestly rather than guessing - When a user asks about a topic covered across multiple documents, synthesize the information and cite all relevant sources - Use read_file to view a full document when the search snippet is not enough context model: provider: openai name: gpt-4o-mini temperature: 0.1 max_tokens: 4096 ingest: sources: - ./docs/**/*.md chunking: strategy: paragraph chunk_size: 512 chunk_overlap: 50 embeddings: provider: openai model: text-embedding-3-small api_key_env: OPENAI_API_KEY tools: - type: filesystem root_path: ./docs read_only: true allowed_extensions: - .md guardrails: max_tokens_per_run: 30000 max_tool_calls: 15 timeout_seconds: 120 max_request_limit: 30 ``` ```bash initrunner ingest rag-agent.yaml initrunner run rag-agent.yaml -p "How do I create a database?" ``` > **What to notice:** `paragraph` chunking preserves natural document structure (better for prose than `fixed`). The role prompt enforces citation discipline — the agent must call `search_documents` before answering and cite sources. The `filesystem` tool lets it read full documents when snippets aren't enough. ### GitHub Project Tracker A declarative API agent that manages GitHub issues without writing any code — endpoints are defined entirely in YAML. ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: github-tracker description: Manages GitHub issues and repos via declarative API endpoints tags: - example - api - github spec: role: | You are a GitHub project assistant. You help users track issues, manage repositories, and stay on top of their projects using the GitHub REST API. Capabilities: - List and search issues (filter by state, labels, assignee) - View issue details including comments and labels - Create new issues with title, body, and labels - Add comments to existing issues - List repositories for any user or organization Guidelines: - When listing issues, default to state=open unless the user specifies otherwise - When creating issues, ask for confirmation before submitting - Format issue lists as numbered summaries with title, state, and labels - Include issue URLs in your responses so users can click through - Use get_current_time for timestamps in comments model: provider: openai name: gpt-4o-mini temperature: 0.1 max_tokens: 4096 tools: - type: api name: github description: GitHub REST API v3 base_url: https://api.github.com headers: Accept: application/vnd.github.v3+json User-Agent: initrunner-github-tracker auth: Authorization: "Bearer ${GITHUB_TOKEN}" endpoints: - name: list_issues method: GET path: "/repos/{owner}/{repo}/issues" description: List issues in a repository parameters: - name: owner type: string required: true - name: repo type: string required: true - name: state type: string required: false default: open - name: labels type: string required: false query_params: state: "{state}" labels: "{labels}" per_page: "10" response_extract: "$[*].{number,title,state,labels[*].name}" timeout: 15 - name: get_issue method: GET path: "/repos/{owner}/{repo}/issues/{issue_number}" description: Get details of a specific issue parameters: - name: owner type: string required: true - name: repo type: string required: true - name: issue_number type: integer required: true timeout: 15 - name: create_issue method: POST path: "/repos/{owner}/{repo}/issues" description: Create a new issue parameters: - name: owner type: string required: true - name: repo type: string required: true - name: title type: string required: true - name: body type: string required: false - name: labels type: string required: false body_template: title: "{title}" body: "{body}" labels: "{labels}" timeout: 15 - name: add_comment method: POST path: "/repos/{owner}/{repo}/issues/{issue_number}/comments" description: Add a comment to an issue parameters: - name: owner type: string required: true - name: repo type: string required: true - name: issue_number type: integer required: true - name: body type: string required: true body_template: body: "{body}" timeout: 15 - type: datetime guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 120 max_request_limit: 30 ``` ```bash export GITHUB_TOKEN=ghp_... initrunner run github-tracker.yaml -i -p "List open bugs in myorg/myrepo" ``` Or, to persist the token across sessions, add it to `~/.initrunner/.env`: ```dotenv GITHUB_TOKEN=ghp_... ``` > **What to notice:** The `api` tool type defines REST endpoints declaratively — no Python code needed. `response_extract` uses JSONPath to trim verbose API responses down to the fields the agent needs. Environment variables (`${GITHUB_TOKEN}`) keep secrets out of YAML. ### Uptime Monitor A daemon agent that checks HTTP endpoints on a cron schedule and alerts Slack on failures. ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: uptime-monitor description: Checks HTTP endpoints and alerts Slack on failures tags: - example - http - slack - monitoring spec: role: | You are an uptime monitor. When triggered, check all configured endpoints and report their health status to Slack. Endpoints to check: - GET /health — main application health - GET /api/status — API service status - GET /readiness — Kubernetes readiness probe For each endpoint: 1. Make the HTTP request using http_request 2. Record the status code and response time 3. Use get_current_time to timestamp the check Reporting rules: - If ALL endpoints return 2xx: send a single green summary to Slack - If ANY endpoint fails (non-2xx or timeout): send a red alert to Slack with the failing endpoint, status code, and error details - Always include the timestamp in the Slack message model: provider: openai name: gpt-4o-mini temperature: 0.0 max_tokens: 2048 tools: - type: http base_url: https://api.example.com allowed_methods: - GET headers: Accept: application/json - type: slack webhook_url: "${SLACK_WEBHOOK_URL}" default_channel: "#ops-alerts" username: Uptime Monitor icon_emoji: ":satellite:" - type: datetime sinks: - type: file path: ./logs/uptime-results.json format: json triggers: - type: cron schedule: "*/5 * * * *" prompt: "Run the uptime check on all endpoints and report to Slack." timezone: UTC guardrails: max_tokens_per_run: 10000 max_tool_calls: 10 timeout_seconds: 60 max_request_limit: 15 daemon_token_budget: 500000 daemon_daily_token_budget: 100000 ``` ```bash initrunner daemon uptime-monitor.yaml ``` > **What to notice:** The `cron` trigger runs the agent every 5 minutes without human intervention. `daemon_token_budget` and `daemon_daily_token_budget` cap spending for unattended agents. The `file` sink logs every result to JSON for later analysis. ### Deployment Checker An autonomous agent that creates a verification plan, executes checks, adapts on failure, and reports results — all without human intervention. See [Autonomous Mode](/docs/autonomy) for details. ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: deployment-checker description: Autonomous deployment verification agent tags: [devops, autonomous, deployment] spec: role: | You are a deployment verification agent. When given one or more URLs to check, create a verification plan, execute each step, and produce a pass/fail report. Workflow: 1. Use update_plan to create a checklist — one step per URL to verify 2. Run curl -sSL -o /dev/null -w "%{http_code} %{time_total}s" for each URL 3. Mark each step passed (2xx) or failed (anything else) 4. If a check fails, adapt your plan — add a retry or investigation step 5. When done, send a Slack summary with pass/fail results per URL 6. Call finish_task with the overall status Keep each plan step concise. Mark steps completed/failed as you go. model: provider: openai name: gpt-4o-mini temperature: 0.0 tools: - type: shell allowed_commands: - curl require_confirmation: false timeout_seconds: 30 - type: slack webhook_url: "${SLACK_WEBHOOK_URL}" default_channel: "#deployments" username: Deploy Checker icon_emoji: ":white_check_mark:" autonomy: max_plan_steps: 6 max_history_messages: 20 iteration_delay_seconds: 1 max_scheduled_per_run: 1 guardrails: max_iterations: 6 autonomous_token_budget: 30000 max_tokens_per_run: 10000 max_tool_calls: 15 session_token_budget: 100000 ``` ```bash initrunner run deployment-checker.yaml -a \ -p "Verify https://api.example.com/health and https://api.example.com/ready" ``` > **What to notice:** The `autonomy` section enables plan-execute-adapt loops. The agent uses `update_plan` to track progress and `finish_task` to signal completion. `max_iterations` and `autonomous_token_budget` in guardrails prevent runaway execution. ### Multi-Agent Delegation A coordinator that delegates research and writing to specialist sub-agents with shared memory. #### `coordinator.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: research-coordinator description: Orchestrator that delegates research and writing tasks tags: - example - multi-agent - delegation spec: role: | You are a research coordinator. Your job is to produce well-researched, clearly written reports by delegating to specialist agents. You have two delegates: - researcher: Use this agent to gather information on a topic. It can fetch web pages and extract key facts. Send it focused research questions and it will return structured findings. - writer: Use this agent to turn raw research notes into polished prose. Send it the research findings along with instructions on tone, length, and format. Workflow: 1. Break the user's request into research questions 2. Delegate each question to the researcher agent 3. Collect and review the research findings 4. Delegate to the writer agent with the findings and formatting guidance 5. Review the final output and return it to the user Always delegate — do not research or write long-form content yourself. model: provider: openai name: gpt-4o-mini temperature: 0.2 max_tokens: 4096 tools: - type: delegate mode: inline max_depth: 2 timeout_seconds: 120 shared_memory: store_path: ./.initrunner/shared-research.db max_memories: 500 agents: - name: researcher role_file: ./agents/researcher.yaml description: Gathers information from the web on a given topic - name: writer role_file: ./agents/writer.yaml description: Turns research notes into polished, structured writing guardrails: max_tokens_per_run: 100000 max_tool_calls: 30 timeout_seconds: 600 max_request_limit: 50 ``` #### `agents/researcher.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: web-researcher description: Research sub-agent that fetches web pages and extracts key facts spec: role: | You are a focused research assistant. Your job is to find and extract key facts on a given topic. Guidelines: - Use fetch_page to retrieve web content when given URLs or when you need to look up specific information - Extract only the most relevant facts — skip boilerplate and ads - Return your findings as a structured bullet-point list - Include the source URL for each fact - If a page is irrelevant, say so and move on - Do not editorialize or write prose — just report the facts model: provider: openai name: gpt-4o-mini temperature: 0.1 max_tokens: 2048 tools: - type: web_reader timeout_seconds: 15 guardrails: max_tokens_per_run: 20000 max_tool_calls: 10 timeout_seconds: 120 ``` #### `agents/writer.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: content-writer description: Writing sub-agent that produces polished prose from research notes spec: role: | You are a skilled technical writer. You receive research notes and produce clear, well-structured content. Guidelines: - Organize information with headings, subheadings, and logical flow - Write in a clear, professional tone unless told otherwise - Cite sources inline where appropriate - Keep paragraphs short and scannable - Use bullet points for lists of items or steps - End with a brief summary or conclusion when appropriate - Do not invent facts — only use information provided in the research notes model: provider: openai name: gpt-4o-mini temperature: 0.7 max_tokens: 4096 guardrails: max_tokens_per_run: 10000 max_tool_calls: 0 timeout_seconds: 60 ``` ```bash initrunner run coordinator.yaml -p "Write a report on WebAssembly adoption in 2025" ``` > **What to notice:** The coordinator never researches or writes directly — it delegates via `delegate_to_researcher` and `delegate_to_writer` tools. `shared_memory` gives all agents access to the same memory database. `max_depth: 2` prevents infinite delegation chains. The writer has `max_tool_calls: 0` — it's a pure generation agent with no tools. ### Code Review Team A team of three personas that review code from different angles — architecture, security, and maintainability — all from a single YAML file. See [Team Mode](/docs/team-mode) for full documentation. ```yaml apiVersion: initrunner/v1 kind: Team metadata: name: code-review-team description: Multi-perspective code review spec: model: provider: openai name: gpt-5-mini personas: architect: "review for design patterns, SOLID principles, and architecture issues" security: "find security vulnerabilities, injection risks, auth issues" maintainer: "check readability, naming, test coverage gaps, docs" tools: - type: filesystem root_path: . read_only: true - type: git repo_path: . read_only: true guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 team_token_budget: 150000 ``` ```bash initrunner run code-review-team.yaml --task "review the auth module" ``` > **What to notice:** `kind: Team` replaces `kind: Agent`. Three personas run sequentially — the architect reviews first, then security builds on the architect's findings, then the maintainer synthesizes everything. All personas share the same read-only tools. Compare this with the [Multi-Agent Delegation](#multi-agent-delegation) example above, which requires three separate YAML files. ### PR Reviewer A code review agent that diffs your current branch against `main` and produces a GitHub-flavored Markdown review ready to paste into a PR comment. **File:** `examples/roles/pr-reviewer.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: pr-reviewer description: Reviews PR changes and produces GitHub-flavored Markdown ready to paste into a PR comment tags: - example - shareable - engineering - review author: initrunner version: "1.0.0" spec: role: | You are a senior engineer performing a pull-request review. Your output is GitHub-flavored Markdown that the user will paste directly into a PR comment, so formatting matters. Workflow: 1. Use git_changed_files with ref="main...HEAD" to list what changed. 2. Use git_diff with ref="main...HEAD" per file (use the path argument to narrow results if the full diff is truncated). 3. Use read_file on changed files when you need surrounding context. 4. Use git_log to read recent commit messages for intent. 5. Produce the formatted review below. Output format (omit any severity section that has no findings): ## Review: [verdict emoji] [Approve | Request Changes | Needs Discussion] **Summary**: One-sentence overall assessment. ### Findings 🔴 **Critical** - **`path/to/file.py:42`** — Description of issue. > Suggested fix or code snippet 🟡 **Major** - ... 🔵 **Minor** - ... ⚪ **Nit** - ... ### What's Good - Positive callout 1 - Positive callout 2 --- _Files reviewed: N | Findings: N critical, N major, N minor, N nit_ Verdict emojis: ✅ Approve, ⚠️ Request Changes, 💬 Needs Discussion. Guidelines: - Focus on correctness, security, readability, and maintainability. - Reference exact file paths and line numbers when possible. - Suggest concrete fixes — include code snippets in fenced blocks. - Be constructive; explain the "why" behind each finding. - Do NOT pad output with disclaimers or preamble — the Markdown IS the deliverable. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: git repo_path: . read_only: true - type: filesystem root_path: . read_only: true guardrails: max_tokens_per_run: 50000 max_tool_calls: 30 timeout_seconds: 300 max_request_limit: 50 ``` ```bash # Review current branch against main initrunner run examples/roles/pr-reviewer.yaml -p "Review changes vs main" # Review a specific range initrunner run examples/roles/pr-reviewer.yaml -p "Review changes in main...feature-branch" # Focus on specific concerns initrunner run examples/roles/pr-reviewer.yaml -p "Review changes vs main, focusing on security" ``` > **What to notice:** Two read-only tools (`git` + `filesystem`) keep the agent strictly non-destructive. The structured output format with severity tiers (🔴 Critical → ⚪ Nit) makes reviews easy to scan and act on. Low temperature (0.1) keeps the analysis consistent across runs. | Tool | Mode | Purpose | |------|------|---------| | `git` | read-only | `git_changed_files`, `git_diff`, `git_log` to inspect the branch diff | | `filesystem` | read-only | `read_file` for surrounding code context | | Setting | Value | |---------|-------| | Temperature | `0.1` | | Max tool calls | `30` | | Timeout | `300s` | ### Changelog for Slack Generates a changelog from git history formatted in Slack `mrkdwn` — ready to paste directly into a Slack channel. **File:** `examples/roles/changelog-slack.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: changelog-slack description: Generates a changelog formatted in Slack mrkdwn, ready to paste into a channel tags: - example - shareable - git - developer-tools author: initrunner version: "1.0.0" spec: role: | You are a release-notes writer. Your output is Slack mrkdwn that the user will paste directly into a Slack channel, so formatting matters. Workflow: 1. Determine the commit range from the user's prompt. - If the prompt includes a tag or range (e.g. "since v1.2.0"), run: shell_execute command="git log v1.2.0..HEAD --pretty=format:\"%h %an %s\"" (adjust the range to match the user's request). - Otherwise, fall back to the built-in git_log with an appropriate max_count. 2. Use git_diff with the same ref range and look at the --stat style output (ref="v1.2.0..HEAD" or similar) to collect file-change stats. 3. Use get_current_time for the date header. 4. Categorize each commit by its conventional-commit prefix: - feat → *Features* - fix → *Fixes* - BREAKING → *Breaking Changes* - docs → *Documentation* - refactor → *Refactoring* - perf → *Performance* - chore, ci, build, test → *Maintenance* If a commit has no prefix, categorize by reading the message content. 5. Format the output as Slack mrkdwn (see template below). Output template (omit empty categories): *Release Notes — YYYY-MM-DD* _v1.2.0 → HEAD (N commits by N contributors)_ *Features* • Brief description (`abc1234`) *Fixes* • Brief description (`111aaa`) *Breaking Changes* • ⚠️ Description (`222bbb`) *Maintenance* • Description (`333ccc`) *Contributors*: @alice, @bob, @carol *Stats*: N commits · N files changed · +NNN / −NNN lines Slack formatting rules: - *bold* for headings and emphasis - _italic_ for subheadings - • (bullet) for list items - `backticks` for commit hashes and code - No Markdown headings (#), no triple backticks — these don't render in Slack Do NOT pad output with disclaimers or preamble — the mrkdwn IS the deliverable. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: git repo_path: . read_only: true - type: shell allowed_commands: - git require_confirmation: false timeout_seconds: 30 - type: datetime guardrails: max_tokens_per_run: 30000 max_tool_calls: 15 timeout_seconds: 120 max_request_limit: 20 ``` ```bash # Changelog since a tag initrunner run examples/roles/changelog-slack.yaml -p "Changelog since v1.2.0" # Last N commits initrunner run examples/roles/changelog-slack.yaml -p "Changelog for the last 20 commits" # Between two tags initrunner run examples/roles/changelog-slack.yaml -p "What changed between v1.1.0 and v1.2.0?" ``` > **What to notice:** The `shell` tool restricted to `allowed_commands: [git]` is intentional — the built-in `git_log` tool accepts no `ref` argument, so range-based changelogs like "since v1.2.0" require `git log v1.2.0..HEAD` via the shell. The output uses Slack `mrkdwn` syntax (`*bold*`, `_italic_`, `•` bullets) rather than Markdown, so it renders correctly when pasted into Slack. | Tool | Mode | Purpose | |------|------|---------| | `git` | read-only | `git_diff` with ref ranges for file-change stats | | `shell` | `allowed_commands: [git]` | `git log ` for range-based history | | `datetime` | — | `get_current_time` for the date header | | Setting | Value | |---------|-------| | Temperature | `0.1` | | Max tool calls | `15` | | Timeout | `120s` | ### CI Failure Explainer Reads a CI/CD log file, identifies the root failure (not cascading noise), and produces a GitHub-flavored Markdown explanation ready to paste into a PR comment or issue. **File:** `examples/roles/ci-explainer.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: ci-explainer description: Reads a CI/CD log file and produces a GitHub-flavored Markdown failure explanation ready to paste into a PR comment or issue tags: - example - shareable - devops - ci author: initrunner version: "1.0.0" spec: role: | You are a CI/CD failure analyst. Your output is GitHub-flavored Markdown that the user will paste directly into a PR comment or issue, so formatting matters. Workflow: 1. Use read_file to read the log file referenced in the user's prompt. 2. Scan the log bottom-up — errors and failures cluster at the end. 3. Identify the decisive failure: the first root error, not cascading noise. 4. Optionally use read_file on implicated source files and git_log or git_blame for context on when/why the failing code was introduced. 5. Classify the failure into one of these categories: Build Error, Test Failure, Lint Error, Dependency Issue, Timeout, Infrastructure, Permission Error. 6. Produce the formatted explanation below. Output format: ## CI Failure: [Category] **TL;DR**: One-sentence plain-English summary of what went wrong. ### What Failed ``` Exact error message or failing command, extracted from the logs ``` ### Why It Failed Plain-English root cause analysis. Reference specific lines and files. ### How to Fix 1. Step-by-step actionable instructions 2. Include exact commands or code changes 3. That someone can follow right now --- _Stage: build/test/lint/deploy | File: `path/file.py:42` | Since: `abc1234`_ Guidelines: - Extract the exact error — do not paraphrase log output in the "What Failed" block. - Distinguish root cause from cascading failures. - Provide concrete, copy-pasteable fix commands or code changes. - Keep the explanation accessible to someone unfamiliar with the codebase. - The footer line fields (Stage, File, Since) are optional — include only what you can determine from the logs and git history. - Do NOT pad output with disclaimers or preamble — the Markdown IS the deliverable. model: provider: openai name: gpt-5-mini temperature: 0.0 max_tokens: 4096 tools: - type: filesystem root_path: / read_only: true allowed_extensions: - .log - .txt - .json - .xml - .yaml - .yml - .py - .js - .ts - .go - .rs - .java - .rb - .sh - type: git repo_path: . read_only: true guardrails: max_tokens_per_run: 40000 max_tool_calls: 20 timeout_seconds: 180 max_request_limit: 25 ``` ```bash # Explain a local log file initrunner run examples/roles/ci-explainer.yaml -p "Explain the failure in /tmp/build.log" # Point to a log in the repo initrunner run examples/roles/ci-explainer.yaml -p "What went wrong in ./ci-output/test-results.log?" # Multiple logs initrunner run examples/roles/ci-explainer.yaml -p "Analyze the build failure in /tmp/build.log and /tmp/test.log" ``` > **What to notice:** The `filesystem` tool uses `root_path: /` so the agent can read logs written anywhere on disk (e.g. `/tmp`). An `allowed_extensions` allowlist restricts it to log, config, and source file types — it cannot read arbitrary binary files. `temperature: 0.0` ensures precise, deterministic log analysis. | Tool | Mode | Purpose | |------|------|---------| | `filesystem` | read-only, root `/` | `read_file` on log files anywhere on disk and source files in the repo | | `git` | read-only | `git_log`, `git_blame` for context on when failing code was introduced | | Setting | Value | |---------|-------| | Temperature | `0.0` (precision for log analysis) | | Max tool calls | `20` | | Timeout | `180s` | ### Tips **Pipe output to clipboard** for instant pasting: ```bash # macOS initrunner run examples/roles/changelog-slack.yaml -p "Last 10 commits" 2>/dev/null | pbcopy # Linux (X11) initrunner run examples/roles/changelog-slack.yaml -p "Last 10 commits" 2>/dev/null | xclip -selection clipboard # Linux (Wayland) initrunner run examples/roles/changelog-slack.yaml -p "Last 10 commits" 2>/dev/null | wl-copy ``` The `2>/dev/null` strips stderr (progress messages) so only the agent's output reaches the clipboard. **Shell aliases** for frequent use: ```bash alias pr-review='initrunner run examples/roles/pr-reviewer.yaml -p' alias changelog='initrunner run examples/roles/changelog-slack.yaml -p' alias ci-explain='initrunner run examples/roles/ci-explainer.yaml -p' # Then: pr-review "Review changes vs main" changelog "Changelog since v1.0.0" ci-explain "Explain /tmp/build.log" ``` ### Thinker An agent that uses the `think` tool to reason step-by-step before acting — useful for complex problem-solving where you want to see the agent's chain of thought. **File:** `examples/roles/thinker.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: thinker description: An agent that reasons step-by-step before acting tags: - example - think author: InitRunner Team version: "1.0.0" spec: role: > You are a careful, methodical assistant. Before answering any question or taking any action, always use the think tool to reason step-by-step. Break down complex problems, consider edge cases, and plan your approach before responding. Use the datetime tool when time-related information is needed. model: provider: openai name: gpt-5-mini temperature: 0.3 max_tokens: 2048 tools: - type: think - type: datetime default_timezone: UTC guardrails: max_tokens_per_run: 10000 max_tool_calls: 20 timeout_seconds: 60 ``` ```bash initrunner run thinker.yaml -p "What day of the week will January 1, 2030 fall on?" ``` > **What to notice:** The `think` tool gives the agent a scratchpad for internal reasoning — its output is not shown to the user but influences the final answer. Combined with low `temperature: 0.3`, this produces more deliberate, accurate responses. The `datetime` tool provides ground truth for time-related questions. ### Script Runner A sysadmin agent with inline shell script tools — each script is defined directly in the YAML with its own parameter schema. **File:** `examples/roles/script-runner.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: script-runner description: A sysadmin agent with inline script tools tags: - example - script - sysadmin author: InitRunner Team version: "1.0.0" spec: role: > You are a system administrator assistant. Use the provided script tools to inspect disk usage, count files, and gather system information. Report results clearly and suggest actions when thresholds are exceeded. model: provider: openai name: gpt-5-mini temperature: 0.2 max_tokens: 2048 tools: - type: script timeout_seconds: 15 scripts: - name: disk_usage description: Check disk usage for a path interpreter: /bin/bash allowed_commands: [df] body: | df -h "$TARGET_PATH" parameters: - name: target_path description: Filesystem path to check required: true - name: count_files description: Count files in a directory (returns the count) interpreter: /bin/bash body: | count=$(find "$DIR" -type f 2>/dev/null | wc -l) echo "$count files found in $DIR" parameters: - name: dir description: Directory path required: true - name: system_info description: Show basic system information interpreter: /bin/bash body: | echo "Hostname: $(hostname)" echo "Kernel: $(uname -r)" echo "Uptime: $(uptime -p 2>/dev/null || uptime)" echo "Memory:" free -h 2>/dev/null || echo "free not available" guardrails: max_tokens_per_run: 10000 max_tool_calls: 10 timeout_seconds: 60 ``` ```bash initrunner run script-runner.yaml -p "Check disk usage on / and report system info" ``` > **What to notice:** The `script` tool type lets you define multiple named scripts inline — each with its own `body`, `interpreter`, `parameters`, and optional `allowed_commands` allowlist. Parameters are injected as uppercase environment variables (e.g. `target_path` becomes `$TARGET_PATH`). No separate script files needed. ### Long-Running Analyst An autonomous research agent with conversation history compaction — keeps context manageable during long multi-source investigations. See [History Compaction](/docs/autonomy#history-compaction) for details. **File:** `examples/roles/long-running-analyst.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: long-running-analyst description: Autonomous research analyst with conversation history compaction tags: - example - autonomous - compaction - research spec: role: | You are a research analyst. Given a topic, methodically gather information from multiple sources, synthesise findings, and produce a structured report. Workflow: 1. Use update_plan to outline your research steps — one step per source or angle 2. Use http_request to fetch data from each source 3. Use get_current_time to timestamp your report 4. Summarise each source's key findings in your plan notes 5. When all sources are processed, write the final report to ./reports/ using write_file 6. Call finish_task with a one-paragraph executive summary Guidelines: - Focus on facts and cite sources - If a source is unreachable, mark the step failed and move on - Keep intermediate notes brief — history compaction will summarise older context - Final report format: title, date, executive summary, per-source sections, conclusion model: provider: openai name: gpt-5-mini temperature: 0.2 tools: - type: http base_url: https://api.example.com allowed_methods: - GET headers: Accept: application/json - type: filesystem root_path: ./reports read_only: false - type: datetime autonomy: max_history_messages: 30 max_plan_steps: 10 iteration_delay_seconds: 1 compaction: enabled: true threshold: 15 tail_messages: 4 model_override: "openai:gpt-4o-mini" guardrails: max_iterations: 20 autonomous_token_budget: 120000 max_tokens_per_run: 15000 max_tool_calls: 40 session_token_budget: 250000 ``` ```bash initrunner run long-running-analyst.yaml -a \ -p "Research the current state of WebAssembly adoption in production environments" ``` > **What to notice:** The `compaction` block is the key addition — with `threshold: 15` and `tail_messages: 4`, older messages are LLM-summarized once the conversation exceeds 15 messages, keeping the 4 most recent verbatim. The `model_override: "openai:gpt-4o-mini"` routes summarization to a cheaper model. This allows `max_iterations: 20` without context window exhaustion. ### Ops Heartbeat A periodic operations agent that processes a markdown checklist via the [Heartbeat trigger](/docs/triggers#heartbeat-trigger). Active hours restrict runs to business hours. **File:** `examples/roles/ops-heartbeat.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: ops-heartbeat description: Periodic ops agent that processes an open-tasks checklist via heartbeat trigger tags: - example - heartbeat - ops - shell - slack spec: role: | You are an operations assistant. Each time you are triggered you receive an updated task checklist. Work through every incomplete item using shell commands and mark them done. Workflow: 1. Read through all unchecked items (lines starting with "- [ ]") 2. For each item, run the appropriate shell command to perform the check 3. Report pass/fail per item to the #ops-alerts Slack channel 4. If a check fails, include the relevant error output in your Slack message Rules: - Never modify production resources — only read / inspect - If a command times out, report it as "timed out" and move to the next item - At the end, post a summary: items checked, passed, failed model: provider: openai name: gpt-5-mini temperature: 0.0 tools: - type: shell allowed_commands: - curl - ping - dig - df - free - uptime - systemctl require_confirmation: false timeout_seconds: 30 - type: slack webhook_url: "${SLACK_WEBHOOK_URL}" default_channel: "#ops-alerts" username: Ops Heartbeat icon_emoji: ":heartbeat:" - type: datetime triggers: - type: heartbeat file: ./ops-checklist.md interval_seconds: 3600 active_hours: [8, 18] timezone: America/New_York guardrails: max_tokens_per_run: 20000 max_tool_calls: 25 timeout_seconds: 180 max_request_limit: 30 ``` The companion checklist file (`ops-checklist.md`): ```markdown # Ops Checklist ## Infrastructure - [ ] Check disk usage on /data (alert if > 80%) - [ ] Verify DNS resolution for api.example.com - [ ] Ping gateway 10.0.0.1 (alert if packet loss > 0%) - [ ] Confirm NTP sync — `systemctl status chronyd` ## Services - [ ] Curl health endpoint https://api.example.com/health (expect 200) - [ ] Curl metrics endpoint https://api.example.com/metrics (expect 200) - [ ] Check available memory (alert if free < 512 MB) ``` ```bash initrunner daemon ops-heartbeat.yaml ``` > **What to notice:** The `heartbeat` trigger reads `ops-checklist.md` every hour and only fires when unchecked items (`- [ ]`) remain. `active_hours: [8, 18]` restricts runs to business hours (Eastern time), so the agent stays quiet overnight. The `allowed_commands` allowlist on the shell tool limits the agent to read-only inspection commands. ### Reloadable Assistant A Slack-connected daemon with hot-reload — edit the YAML while the daemon is running and changes take effect automatically without a restart. **File:** `examples/roles/reloadable-assistant.yaml` ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: reloadable-assistant description: Slack daemon with hot-reload — edit YAML, see changes live tags: - example - daemon - hot-reload - slack - cron spec: role: | You are a team assistant running as a long-lived daemon. You respond to Slack messages and run periodic summaries on a cron schedule. Responsibilities: 1. Answer questions from the team in Slack 2. Every four hours, summarise recent activity and post to #team-updates 3. Use shell commands to gather system metrics when asked Tone: concise, friendly, and professional. Prefer bullet points over prose. model: provider: openai name: gpt-5-mini temperature: 0.3 max_tokens: 4096 tools: - type: slack webhook_url: "${SLACK_WEBHOOK_URL}" default_channel: "#team-updates" username: Team Assistant icon_emoji: ":robot_face:" - type: shell allowed_commands: - uptime - df - free - date require_confirmation: false timeout_seconds: 15 - type: datetime triggers: - type: cron schedule: "0 */4 * * *" prompt: "Summarise recent activity and post a status update to Slack." timezone: UTC daemon: hot_reload: true reload_debounce_seconds: 2.0 guardrails: max_tokens_per_run: 20000 max_tool_calls: 15 timeout_seconds: 120 max_request_limit: 20 daemon_token_budget: 500000 daemon_daily_token_budget: 200000 ``` ```bash initrunner daemon reloadable-assistant.yaml ``` > **What to notice:** The `daemon.hot_reload: true` setting (on by default) watches the YAML file for changes. Edit `spec.role`, tweak `guardrails`, or adjust the cron `schedule` — the daemon picks up changes after a 2-second debounce. What does NOT hot-reload: model provider changes, adding/removing trigger types, and `.env` files (those require a restart). See [Hot-Reload](/docs/triggers#hot-reload) for details. ## Full Example Catalog Every example below can be previewed with `initrunner examples show ` and copied with `initrunner examples copy `. Source files are also available in the [GitHub examples directory](https://github.com/vladkesler/initrunner/tree/main/examples). ### Role Examples Single-agent configurations — one YAML file, one purpose. | Name | Description | |------|-------------| | `code-reviewer` | Read-only code review with git + filesystem tools | | `data-analyst` | SQL queries, Python analysis, and report writing | | `rag-agent` | Knowledge base Q&A with document ingestion and citation | | `github-tracker` | Manage GitHub issues via declarative API endpoints | | `uptime-monitor` | Cron-scheduled HTTP checks with Slack alerts | | `deployment-checker` | Autonomous deployment verification with plan-execute loops | | `memory-assistant` | Personal assistant that learns across sessions | | `custom-tools-demo` | Custom Python tool functions with config injection | | `security-scanner` | Static analysis and dependency audit agent | | `docker-sandbox` | Code execution agent with Docker container isolation | | `log-analyzer` | Parse and summarize application logs | | `db-migrator` | Generate and validate database migration scripts | | `api-tester` | Automated REST API endpoint testing | | `doc-generator` | Generate documentation from source code | | `slack-responder` | Auto-respond to Slack messages with context-aware answers | | `incident-responder` | On-call triage and runbook execution | | `changelog-writer` | Generate changelogs from git history | | `pr-summarizer` | Summarize pull request changes for reviewers | | `web-searcher` | Research assistant with web and news search | | `full-tools-assistant` | All 10 zero-config tools enabled (filesystem, git, shell, python, web_reader, datetime, calculator, json, csv, regex) | | `email-assistant` | Search, read, and summarize emails via IMAP | | `telegram-assistant` | Telegram bot that responds to messages via long-polling | | `discord-assistant` | Discord bot that responds to DMs and @mentions | | `thinker` | Step-by-step reasoning with the think tool | | `script-runner` | Sysadmin agent with inline shell script tools | | `long-running-analyst` | Autonomous research with conversation history compaction | | `ops-heartbeat` | Periodic ops checks via heartbeat trigger and checklist | | `reloadable-assistant` | Slack daemon with hot-reload — edit YAML, see changes live | ### Team Examples Multi-persona teams defined with `kind: Team`.

Use `uv`, `pipx`, or create a venv first. ## Docker > **Note:** The Docker image ships with **all extras** pre-installed — no need to specify extras when using Docker. Pull and run in one command: ```bash docker run --rm -e OPENAI_API_KEY vladkesler/initrunner:latest --version ``` Or use Docker Compose for the full dashboard: ```bash curl -O https://raw.githubusercontent.com/vladkesler/initrunner/main/docker-compose.yml docker compose up -d ``` Build locally with custom extras: ```bash docker build -t initrunner . docker build --build-arg EXTRAS="dashboard,anthropic" -t initrunner-custom . ``` If using Ollama on the host from inside a container, set `base_url: http://host.docker.internal:11434/v1` in your role YAML. See [Docker](/docs/docker) for full Docker documentation. ## Cloud Deploy Deploy the dashboard to a cloud platform with one click — no local Docker required: - **Railway** — Deploy button, auto-builds from `railway.json` - **Render** — Deploy button, Blueprint provisions a 1 GB persistent disk - **Fly.io** — CLI-based deploy with `fly launch` and `fly deploy` All platforms seed 5 example roles on first boot and expose the dashboard on port 8420. See [Cloud Deploy](/docs/cloud-deploy) for full instructions. ## Extras > **Tip:** Not sure which extras you need? Install `[all]` — it includes every provider, feature, and interface so everything just works out of the box. ### Install all extras (recommended) ```bash # pip pip install "initrunner[all]" # uv uv tool install "initrunner[all]" # or in a venv: uv pip install "initrunner[all]" # pipx pipx install "initrunner[all]" # shell installer curl -fsSL https://initrunner.ai/install.sh | sh -s -- --extras all ``` ### Pick and choose You can combine specific extras with commas: ```bash # pip pip install "initrunner[ingest,search,dashboard]" # uv uv tool install "initrunner[ingest,search,dashboard]" # pipx pipx install "initrunner[ingest,search,dashboard]" # shell installer (comma-separated) curl -fsSL https://initrunner.ai/install.sh | sh -s -- --extras ingest,search,dashboard ``` ### Available extras #### LLM Providers | Extra | What it adds | |-------|--------------| | `all-models` | All LLM providers (Anthropic, Google, Groq, Mistral, Cohere, Bedrock, xAI) | | `anthropic` | Anthropic provider (Claude) | | `google` | Google provider (Gemini) | | `groq` | Groq provider | | `mistral` | Mistral provider | | `cohere` | Cohere provider (Command R) | | `bedrock` | AWS Bedrock provider | | `xai` | xAI provider (Grok) — uses OpenAI SDK | #### Features | Extra | What it adds | |-------|--------------| | `ingest` | PDF, DOCX, XLSX ingestion (base text ingestion is built-in) | | `search` | Web search via DuckDuckGo (free, no API key) | | `audio` | YouTube transcript extraction | | `safety` | Profanity filter for content policy | | `observability` | OpenTelemetry tracing and metrics export | #### Messaging Triggers | Extra | What it adds | |-------|--------------| | `telegram` | Telegram bot trigger | | `discord` | Discord bot trigger | | `channels` | Both Telegram and Discord | #### Interfaces | Extra | What it adds | |-------|--------------| | `tui` | Terminal TUI dashboard (Textual) | | `dashboard` | Web dashboard (FastAPI + HTMX + DaisyUI) | > **Note:** `local-embeddings` (fastembed) is defined but **not yet implemented**. Use the `ollama` provider instead for local embeddings — see [Providers](/docs/providers). ## Development Setup ```bash git clone https://github.com/vladkesler/initrunner.git cd initrunner uv sync uv run pytest tests/ -v uv run ruff check . uv run initrunner --version ``` ## Environment Variables By default, InitRunner stores data in `~/.initrunner/`. Override with `INITRUNNER_HOME`: ```bash export INITRUNNER_HOME=/data/initrunner initrunner run role.yaml -p "hello" ``` Or, to persist across sessions, add it to `~/.initrunner/.env`: ```dotenv INITRUNNER_HOME=/data/initrunner ``` Resolution order: `INITRUNNER_HOME` > `XDG_DATA_HOME/initrunner` > `~/.initrunner`. ## Platform Notes - **Python 3.11–3.12** is required. - **Linux / macOS / WSL** are fully supported. - **Windows** works but systemd-related compose features (`compose install/start/stop`) are unavailable. - **Docker**: if using Ollama on the host from inside a container, set `base_url: http://host.docker.internal:11434/v1` in your role YAML. ### Docker # Docker Run InitRunner in a container without installing Python or managing dependencies. Images ship with **all extras** pre-installed (`EXTRAS="all"`) — every provider, feature, and interface works out of the box. > **Looking for Docker sandbox?** To run agent tool execution (shell, Python, scripts) inside isolated Docker containers, see [Docker Sandbox](/docs/docker-sandbox). > **Tip:** Want to skip Docker setup entirely? [Cloud Deploy](/docs/cloud-deploy) offers one-click deployment to Railway, Render, and Fly.io. ## Images Official images are published to both registries: | Registry | Image | |----------|-------| | GitHub Container Registry | `ghcr.io/vladkesler/initrunner:latest` | | Docker Hub | `vladkesler/initrunner:latest` | Both are identical — use whichever your environment prefers. ## Quick Start ### One-shot prompt ```bash docker run --rm -e OPENAI_API_KEY \ -v ./roles:/roles \ ghcr.io/vladkesler/initrunner:latest \ run /roles/my-agent.yaml -p "Hello" ``` ### Interactive chat ```bash docker run --rm -it -e OPENAI_API_KEY \ -v ./roles:/roles \ ghcr.io/vladkesler/initrunner:latest \ run /roles/my-agent.yaml -i ``` ### Chat with cherry-picked tools ```bash docker run --rm -it -e OPENAI_API_KEY \ -v ./roles:/roles \ ghcr.io/vladkesler/initrunner:latest \ chat --tools git --tools filesystem ``` ### Chat with document ingestion ```bash docker run --rm -it -e OPENAI_API_KEY \ -v ./docs:/docs \ ghcr.io/vladkesler/initrunner:latest \ chat --ingest /docs ``` ### Web dashboard ```bash docker run -d -e OPENAI_API_KEY \ -v ./roles:/roles \ -v initrunner-data:/data \ -p 8420:8420 \ ghcr.io/vladkesler/initrunner:latest \ ui --role-dir /roles ``` Open [http://localhost:8420](http://localhost:8420) to access the dashboard. ### Telegram bot ```bash docker run -d -e OPENAI_API_KEY -e TELEGRAM_BOT_TOKEN \ -v ./roles:/roles \ ghcr.io/vladkesler/initrunner:latest \ chat --telegram ``` ### API server ```bash docker run -d -e OPENAI_API_KEY \ -v ./roles:/roles \ -p 8000:8000 \ ghcr.io/vladkesler/initrunner:latest \ serve ``` The API is available at [http://localhost:8000](http://localhost:8000). ## Docker Compose Create a `docker-compose.yml`: ```yaml services: initrunner: # GHCR (default) — or use vladkesler/initrunner:latest (Docker Hub) image: ghcr.io/vladkesler/initrunner:latest # build: . # uncomment to build from source ports: - "8420:8420" # Web dashboard - "8000:8000" # API server volumes: - ./roles:/roles - initrunner-data:/data environment: - OPENAI_API_KEY=${OPENAI_API_KEY:-} - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY:-} - GOOGLE_API_KEY=${GOOGLE_API_KEY:-} - INITRUNNER_DASHBOARD_API_KEY=${INITRUNNER_DASHBOARD_API_KEY:-} # persistent dashboard key restart: unless-stopped command: ["ui", "--role-dir", "/roles"] volumes: initrunner-data: ``` Start the stack: ```bash docker compose up -d ``` ## Building Locally Build the image from the repository root: ```bash docker build -t initrunner . docker run --rm initrunner --version ``` ### Customizing extras The default image includes **all extras** (`EXTRAS="all"`). You can narrow it down with a build arg: ```bash docker build --build-arg EXTRAS="dashboard,anthropic" -t initrunner-custom . ``` ## Environment Variables Pass API keys and configuration as environment variables: | Variable | Description | |----------|-------------| | `OPENAI_API_KEY` | OpenAI API key | | `ANTHROPIC_API_KEY` | Anthropic API key | | `GOOGLE_API_KEY` | Google API key | | `INITRUNNER_HOME` | Data directory inside the container (defaults to `/data`) | | `INITRUNNER_DASHBOARD_API_KEY` | Fixed dashboard API key (persists across container restarts) | ## Volumes | Container Path | Purpose | |----------------|---------| | `/roles` | Mount your role YAML files here | | `/data` | Persistent state — sessions, memory, vector indexes | ## Ports | Port | Service | |------|---------| | `8000` | API server (`initrunner serve`) | | `8420` | Web dashboard (`initrunner ui`) | ## Docker Entrypoint As of v1.8.0, the Docker image uses a custom entrypoint that automatically seeds 5 example roles (`hello-world`, `web-searcher`, `memory-assistant`, `code-reviewer`, `full-tools-assistant`) into `/data/roles/` on first boot. If the directory already contains files, seeding is skipped. This is the same entrypoint used by the [Cloud Deploy](/docs/cloud-deploy) platforms (Railway, Render, Fly.io). If you want to disable seeding, mount your own role directory at `/data/roles/` before starting the container. ## Ollama Integration If Ollama runs on the host machine, the container cannot reach `localhost`. Use the Docker host gateway address in your role YAML: ```yaml spec: model: provider: ollama base_url: http://host.docker.internal:11434/v1 ``` ### Cloud Deploy # Cloud Deploy Deploy the InitRunner dashboard to a cloud platform in minutes. All options build from the Dockerfile, seed example roles on first boot, and expose the web dashboard on port 8420. > **Tip:** If you prefer running containers locally, see [Docker](/docs/docker) for images, Compose, volumes, and build options. ## Prerequisites 1. **LLM API key** — at least one of `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, or `GOOGLE_API_KEY` 2. **Dashboard password** (recommended) — set `INITRUNNER_DASHBOARD_API_KEY` to protect your public URL ## Deploy to Railway [![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/template/FROM_REPO?referralCode=...) 1. Click the button above (or create a new project from this repo) 2. Set environment variables in the Railway dashboard: - `OPENAI_API_KEY` (or your preferred provider key) - `INITRUNNER_DASHBOARD_API_KEY` — password for the dashboard 3. Railway builds from `railway.json` and starts the dashboard automatically 4. **Volume**: Create a persistent volume mounted at `/data` in the Railway UI to keep roles, memory, and audit data across deploys The health check at `/api/health` confirms the service is running. ## Deploy to Render [![Deploy to Render](https://render.com/images/deploy-to-render-button.svg)](https://render.com/deploy?repo=https://github.com/vladkesler/initrunner) 1. Click the button above 2. Render reads `render.yaml` and creates the service with a 1 GB persistent disk at `/data` 3. Set your API keys in the environment variable prompts during setup 4. The service starts automatically once the build completes Render's Blueprint handles disk provisioning — no manual volume setup needed. ## Deploy to Fly.io Fly.io requires the CLI. Install it from [fly.io/docs/flyctl](https://fly.io/docs/flyctl/install/). ```bash # Clone the repo git clone https://github.com/vladkesler/initrunner.git cd initrunner # Launch (uses deploy/fly.toml) fly launch --config deploy/fly.toml --copy-config --no-deploy # Create persistent storage fly volumes create initrunner_data --region iad --size 1 # Set secrets fly secrets set OPENAI_API_KEY=sk-... fly secrets set INITRUNNER_DASHBOARD_API_KEY=your-password # Deploy fly deploy --config deploy/fly.toml ``` The dashboard will be available at `https://initrunner.fly.dev` (or your chosen app name). ## Environment Variables | Variable | Required | Description | |----------|----------|-------------| | `OPENAI_API_KEY` | Yes* | OpenAI API key (default provider) | | `ANTHROPIC_API_KEY` | No | Anthropic API key (for Claude models) | | `GOOGLE_API_KEY` | No | Google AI API key (for Gemini models) | | `INITRUNNER_DASHBOARD_API_KEY` | Recommended | Password protecting the web dashboard | | `INITRUNNER_HOME` | No | Data directory (default: `/data`) | \*At least one LLM provider key is required. Which one depends on the models used in your roles. ## Post-Deploy ### Accessing the Dashboard Open the URL provided by your platform. If you set `INITRUNNER_DASHBOARD_API_KEY`, you'll be prompted for the password on first visit. The dashboard comes pre-loaded with 5 example roles: - **hello-world** — minimal agent for testing - **web-searcher** — web search and summarization - **memory-assistant** — persistent memory across sessions - **code-reviewer** — code review with git tools - **full-tools-assistant** — all zero-config tools enabled ### Adding Custom Roles Upload new roles through the dashboard's role editor, or mount a volume with your role files. On platforms with persistent storage, roles saved to `/data/roles/` persist across deploys. ### Storage All platforms mount `/data` as persistent storage. This directory holds: | Path | Contents | |------|----------| | `/data/roles/` | Agent role YAML files | | `/data/memory/` | Persistent agent memory | | `/data/audit/` | Audit trail database | | `/data/vectors/` | Vector store for RAG | ## Extended Tools The seeded `full-tools-assistant` role includes all tools that work without extra configuration. To add tools that require credentials or config, edit the role and add: ```yaml # HTTP client (requires base_url) - type: http base_url: https://api.example.com # SQL database (requires connection string) - type: sql database: postgresql://user:pass@host/db # Email (requires SMTP credentials) - type: email smtp_host: smtp.gmail.com smtp_port: 587 # Slack (requires webhook URL) - type: slack webhook_url: https://hooks.slack.com/services/... ``` ## API Server Alternative To run an OpenAI-compatible API server instead of the dashboard, change the start command: ``` initrunner serve /data/roles/full-tools-assistant.yaml --host 0.0.0.0 --port 8000 ``` Update the port mapping and health check path accordingly (`/v1/models` for the API server). ## Troubleshooting ### "No API key configured" Set at least one provider API key (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, or `GOOGLE_API_KEY`) in your platform's environment variables. ### Empty dashboard (no roles) The entrypoint script seeds roles only if `/data/roles/` is empty or missing. If you mounted an empty host directory, it overrides the seeding. Either: - Remove the volume mount and let the container manage `/data/roles/` - Copy roles manually: `docker cp container:/opt/initrunner/example-roles/ ./roles/` ### Health check failures The health check hits `/api/health` on port 8420. Ensure: - Port 8420 is exposed and mapped correctly - The `INITRUNNER_HOME` env var is set to `/data` (or the correct data directory) - The container has finished building and starting (allow 30–60s for first boot) ### Volume not persisting Each platform handles storage differently: | Platform | How to set up persistent storage | |----------|----------------------------------| | **Railway** | Create a volume in the UI and mount it at `/data` | | **Render** | The `render.yaml` Blueprint creates a 1 GB disk automatically | | **Fly.io** | Run `fly volumes create initrunner_data --region iad --size 1` | ## Next Steps - [Docker](/docs/docker) — Run InitRunner locally in containers - [Examples](/docs/examples) — Complete, runnable agents for common use cases - [Troubleshooting](/docs/troubleshooting) — Common issues and frequently asked questions ### Tutorial: Build a Site Monitor Agent # Tutorial: Build a Site Monitor Agent This hands-on tutorial walks you through building a **site monitor agent** — an agent that fetches web pages, summarizes changes, saves timestamped reports, remembers findings across sessions, and runs on a schedule. By the end, you'll have used every major InitRunner feature. Each step builds on the previous one and shows the **complete YAML** so you can copy-paste at any point. ## Prerequisites - **Python 3.11–3.12** installed - **InitRunner** installed — see [Installation](/docs/installation) - **An API key** configured — see [Setup](/docs/setup) The examples below use `openai/gpt-5-mini`. To use a different provider, swap the `model:` block — see [Provider Configuration](/docs/providers) for options including Anthropic, Google, Ollama, and others. > **Hitting API issues?** Add `--dry-run` to any `initrunner run` command to simulate with a test model. This lets you verify your YAML and follow along without making API calls. Create a working directory for the tutorial: ```bash mkdir site-monitor && cd site-monitor ``` ## Step 1: Your First Agent — A Simple Summarizer Every agent starts with a `role.yaml` file. Create one with the minimum required fields: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You help users track changes to web pages by fetching content, summarizing it, and reporting what changed. Be concise and focus on meaningful changes. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 2048 guardrails: max_tokens_per_run: 10000 max_tool_calls: 5 timeout_seconds: 60 ``` Every role file has four top-level keys: - **`apiVersion`**: Always `initrunner/v1` - **`kind`**: Always `Agent` - **`metadata`**: Name (lowercase, hyphens only), description, and optional tags/author/version - **`spec`**: The agent's behavior — system prompt (`role`), model, tools, and guardrails Validate the file, then run it: ```bash initrunner validate role.yaml initrunner run role.yaml -p "What can you help me with?" ``` The agent responds based on its system prompt. Without tools, it can only answer from its training data — it can't actually fetch web pages yet. > **Troubleshooting:** If you get an API key error, make sure your key is set in the environment (`OPENAI_API_KEY`) or configured via `initrunner setup`. If the provider SDK is missing, install it with `pip install initrunner[all-models]` or the specific extra (e.g., `pip install initrunner[anthropic]`). ## Step 2: Interactive Mode — Chatting With Your Agent You don't need to change the YAML to try interactive mode. Run the same agent with `-i`: ```bash initrunner run role.yaml -i ``` This starts a multi-turn REPL where you can have a conversation: ``` You: What kind of sites would be good to monitor? Agent: Good candidates for monitoring include... You: How often should I check a news site? Agent: For news sites, checking every few hours... You: quit ``` The agent keeps context within a session — it remembers what you discussed earlier in the conversation. When you exit (type `quit`, `exit`, or press Ctrl+D), the session ends and context is lost. Step 5 adds memory to persist information across sessions. > **Troubleshooting:** To exit the REPL, type `quit`, `exit`, or press Ctrl+D. If the agent seems stuck, press Ctrl+C to cancel the current request. ## Step 3: Adding Tools — Fetching Pages and Saving Reports Tools give your agent capabilities beyond conversation. Add three tools to fetch web pages, get timestamps, and save reports: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You fetch web pages, summarize their content, and save reports. When asked to monitor a page: 1. Use current_time() to get today's date 2. Use fetch_page() to retrieve the page content 3. Summarize the key content and any notable elements 4. Save a report using write_file() with a timestamped filename like "2026-02-16-example-com.md" (date-domain format) 5. Include the date, URL, and summary in the report content Always use timestamped filenames so reports can be searched by date. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: web_reader - type: datetime - type: filesystem root_path: ./reports read_only: false allowed_extensions: - .md guardrails: max_tokens_per_run: 30000 max_tool_calls: 15 timeout_seconds: 120 ``` Three tools are now available to the agent: - **`web_reader`**: Provides `fetch_page(url)` — fetches a URL and returns its content as markdown - **`datetime`**: Provides `current_time()` and `parse_date()` — for timestamps - **`filesystem`**: Provides `read_file()`, `list_directory()`, and `write_file()` — file operations scoped to `./reports` Notice `read_only: false` on the filesystem tool — this enables `write_file()`. The `root_path` and `allowed_extensions` sandbox the agent to only write `.md` files inside `./reports/`. Validate and run: ```bash initrunner validate role.yaml initrunner run role.yaml -p "Monitor https://example.com and save a report" ``` Then check the output: ```bash ls reports/ ``` You should see a file like `2026-02-16-example-com.md` containing a dated summary of the page. > **Troubleshooting:** If you get "permission denied" on write, check that `read_only: false` is set (the default is `true`). If URL fetching fails, check your network connection. The `web_reader` tool respects `allowed_domains` and `blocked_domains` if you need to restrict access — see [Tool Reference](/docs/tools). ## Step 4: Autonomous Mode — Monitoring Multiple Sites Autonomous mode lets the agent execute multi-step tasks in a loop — plan, act, observe, repeat — without you prompting each step. > **Cost and safety note:** Autonomous mode runs multiple LLM calls in a loop. The `max_iterations` guardrail caps the number of iterations. Start low (5) and increase as needed. You can also set `autonomous_token_budget` to cap total token usage. See [Autonomous Execution](/docs/autonomy) for details. Add `max_iterations: 5` to guardrails to limit the agentic loop: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You fetch web pages, summarize their content, and save reports. When asked to monitor a page: 1. Use current_time() to get today's date 2. Use fetch_page() to retrieve the page content 3. Summarize the key content and any notable elements 4. Save a report using write_file() with a timestamped filename like "2026-02-16-example-com.md" (date-domain format) 5. Include the date, URL, and summary in the report content When monitoring multiple pages, compare findings across sites and note similarities and differences. Save individual reports for each site, then write a consolidated comparison report. Always use timestamped filenames so reports can be searched by date. model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: web_reader - type: datetime - type: filesystem root_path: ./reports read_only: false allowed_extensions: - .md guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 max_iterations: 5 ``` Validate, then run in autonomous mode with `-a`: ```bash initrunner validate role.yaml initrunner run role.yaml -a -p "Monitor these 3 sites and write a comparison report: https://example.com, https://example.org, https://example.net" ``` The agent autonomously fetches each URL, writes individual reports, then produces a consolidated comparison — all in one run. You'll see it iterate through plan-execute-reflect cycles until it finishes or hits `max_iterations`. > **Troubleshooting:** If the agent loops without finishing, lower `max_iterations` or add `autonomous_token_budget: 30000` to guardrails for a hard token cap. If token usage is too high, use a smaller model or reduce `max_tokens`. ## Step 5: Memory — Tracking Changes Over Time Memory lets your agent persist information across sessions. Add a `memory:` block: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You fetch web pages, summarize their content, and save reports. When asked to monitor a page: 1. Use current_time() to get today's date 2. Use fetch_page() to retrieve the page content 3. Summarize the key content and any notable elements 4. Save a report using write_file() with a timestamped filename like "2026-02-16-example-com.md" (date-domain format) 5. Include the date, URL, and summary in the report content When monitoring multiple pages, compare findings across sites and note similarities and differences. Save individual reports for each site, then write a consolidated comparison report. Always use timestamped filenames so reports can be searched by date. Memory guidelines: - After each monitoring run, use remember() to store key findings with category "monitoring" (e.g., "example.com homepage featured a new product launch on 2026-02-16") - Before reporting, use recall() to check what you found last time and highlight what changed - Use list_memories() when asked for a summary of past observations model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: web_reader - type: datetime - type: filesystem root_path: ./reports read_only: false allowed_extensions: - .md memory: max_sessions: 10 semantic: max_memories: 1000 max_resume_messages: 20 guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 max_iterations: 5 ``` The `memory:` block enables two things: - **Short-term session persistence**: Conversation history is saved, so you can resume sessions with `--resume` - **Long-term memory**: Up to five tools are auto-registered — `remember()`, `recall()`, `list_memories()`, `learn_procedure()`, and `record_episode()` — for storing and searching facts across sessions. See [Memory](/docs/memory) for details on semantic, episodic, and procedural memory types. Try it in interactive mode: ```bash initrunner validate role.yaml initrunner run role.yaml -i ``` ``` You: Monitor https://example.com and save a report Agent: [fetches page, saves report, remembers findings] You: quit ``` Start a new session and ask about previous findings: ```bash initrunner run role.yaml -i ``` ``` You: What did you find last time you checked example.com? Agent: Based on my memories, when I last checked example.com on... ``` Or resume the previous session directly with `--resume`: ```bash initrunner run role.yaml -i --resume ``` This restores the conversation history so the agent has full context from where you left off — not just semantic memories, but the actual messages. For more details on short-term vs long-term memory, see [Memory System](/docs/memory). > **Troubleshooting:** If memories aren't persisting, make sure the `memory:` block is present in your YAML. The `--resume` flag requires `memory:` to be configured — without it, there's nothing to resume from. ## Step 6: Knowledge Base — Searching Past Reports By now your `./reports/` directory has several timestamped markdown files from the previous steps. You can turn these into a searchable knowledge base with the `ingest:` block. If you don't have enough reports yet, create a few samples: ```bash mkdir -p reports cat > reports/2026-02-14-example-com.md << 'EOF' # Site Report: example.com **Date:** 2026-02-14 **URL:** https://example.com ## Summary The Example Domain page displays a simple informational page with a heading "Example Domain" and a short paragraph explaining this domain is for use in illustrative examples. Contains a link to IANA for more information. EOF cat > reports/2026-02-15-example-com.md << 'EOF' # Site Report: example.com **Date:** 2026-02-15 **URL:** https://example.com ## Summary No changes detected from previous check. The page still shows the standard "Example Domain" content with the IANA reference link. EOF ``` Add the `ingest:` block to your role: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You fetch web pages, summarize their content, and save reports. When asked to monitor a page: 1. Use current_time() to get today's date 2. Use fetch_page() to retrieve the page content 3. Summarize the key content and any notable elements 4. Save a report using write_file() with a timestamped filename like "2026-02-16-example-com.md" (date-domain format) 5. Include the date, URL, and summary in the report content When monitoring multiple pages, compare findings across sites and note similarities and differences. Save individual reports for each site, then write a consolidated comparison report. Always use timestamped filenames so reports can be searched by date. Memory guidelines: - After each monitoring run, use remember() to store key findings with category "monitoring" (e.g., "example.com homepage featured a new product launch on 2026-02-16") - Before reporting, use recall() to check what you found last time and highlight what changed - Use list_memories() when asked for a summary of past observations Knowledge base guidelines: - When asked about past monitoring results, ALWAYS call search_documents() first to find relevant reports - Cite the report date and URL when referencing past findings - Use read_file() to view a full report when the search snippet isn't enough context model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: web_reader - type: datetime - type: filesystem root_path: ./reports read_only: false allowed_extensions: - .md ingest: sources: - ./reports/**/*.md chunking: strategy: fixed chunk_size: 512 chunk_overlap: 50 memory: max_sessions: 10 semantic: max_memories: 1000 max_resume_messages: 20 guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 max_iterations: 5 ``` Validate, then index the reports: ```bash initrunner validate role.yaml initrunner ingest role.yaml ``` The ingestion pipeline reads all `.md` files matching the glob pattern, chunks them, generates embeddings, and stores them in a local SQLite vector database. This auto-registers a `search_documents(query)` tool for the agent. Now query your report history: ```bash initrunner run role.yaml -p "When did I last check example.com? What did the page contain?" ``` The agent searches the indexed reports and answers with specific dates and content from your timestamped files. When you add new reports (from monitoring runs), re-run `initrunner ingest role.yaml` to update the index. For more on RAG patterns, see [Ingestion Pipeline](/docs/ingestion) and [RAG Guide](/docs/rag-guide). > **Troubleshooting:** If search returns nothing, make sure you ran `initrunner ingest role.yaml` after creating the reports. If results seem off, check that your report files have substantive content for the embeddings to index. ## Step 7: Scheduled Monitoring — Triggers and Daemon Mode Triggers let your agent run automatically on a schedule. Add a `triggers:` block with a cron schedule and a `sinks:` block to log results: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You fetch web pages, summarize their content, and save reports. When asked to monitor a page: 1. Use current_time() to get today's date 2. Use fetch_page() to retrieve the page content 3. Summarize the key content and any notable elements 4. Save a report using write_file() with a timestamped filename like "2026-02-16-example-com.md" (date-domain format) 5. Include the date, URL, and summary in the report content When monitoring multiple pages, compare findings across sites and note similarities and differences. Save individual reports for each site, then write a consolidated comparison report. Always use timestamped filenames so reports can be searched by date. Memory guidelines: - After each monitoring run, use remember() to store key findings with category "monitoring" (e.g., "example.com homepage featured a new product launch on 2026-02-16") - Before reporting, use recall() to check what you found last time and highlight what changed - Use list_memories() when asked for a summary of past observations Knowledge base guidelines: - When asked about past monitoring results, ALWAYS call search_documents() first to find relevant reports - Cite the report date and URL when referencing past findings - Use read_file() to view a full report when the search snippet isn't enough context model: provider: openai name: gpt-5-mini temperature: 0.1 max_tokens: 4096 tools: - type: web_reader - type: datetime - type: filesystem root_path: ./reports read_only: false allowed_extensions: - .md ingest: sources: - ./reports/**/*.md chunking: strategy: fixed chunk_size: 512 chunk_overlap: 50 memory: max_sessions: 10 semantic: max_memories: 1000 max_resume_messages: 20 triggers: - type: cron schedule: "* * * * *" prompt: "Monitor https://example.com and save a report. Compare with previous findings." sinks: - type: file path: ./logs/monitor.jsonl format: json guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 max_iterations: 5 ``` The trigger fires every minute (for demo purposes) and sends the configured `prompt` to the agent. The file sink logs every run result as JSON to `./logs/monitor.jsonl`. Validate and start the daemon: ```bash initrunner validate role.yaml initrunner daemon role.yaml ``` Wait about a minute and you should see the trigger fire. The agent fetches the page, saves a report, and the result is logged to the sink file. Check the output: ```bash cat logs/monitor.jsonl ``` Stop the daemon with Ctrl+C. For production use, change the schedule to something practical: ```yaml triggers: - type: cron schedule: "0 * * * *" # every hour prompt: "Monitor https://example.com and save a report." ``` Or daily at 9am: ```yaml triggers: - type: cron schedule: "0 9 * * *" # daily at 9:00 UTC prompt: "Monitor https://example.com and save a report." timezone: US/Eastern # optional: set timezone ``` For more on triggers and daemon mode, see [Triggers](/docs/triggers) and [Sinks](/docs/sinks). > **Troubleshooting:** If the trigger never fires, double-check the cron syntax — `* * * * *` means every minute. If the daemon exits immediately, run `initrunner validate role.yaml` to check for YAML errors. ## The Complete Agent Here's the full `role.yaml` with every feature assembled: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: site-monitor description: Monitors websites and summarizes changes spec: role: | You are a site monitoring assistant. You fetch web pages, summarize their content, and save reports. When asked to monitor a page: 1. Use current_time() to get today's date 2. Use fetch_page() to retrieve the page content 3. Summarize the key content and any notable elements 4. Save a report using write_file() with a timestamped filename like "2026-02-16-example-com.md" (date-domain format) 5.

Each produces copy-paste-ready output — run one command, grab the result. This tutorial walks through all three with hands-on exercises. No YAML editing required. > For the full configuration reference, see [Examples](/docs/examples). To learn InitRunner concepts step-by-step, see the [Site Monitor Tutorial](/docs/tutorial). ## Prerequisites - **Python 3.11–3.12** installed - **InitRunner** installed — see [Installation](/docs/installation) - **An API key** configured — see [Setup](/docs/setup) - **A git repository** with some commit history (your own project works) The templates use `openai/gpt-5-mini` by default. To use a different provider, see [Make Them Yours](#make-them-yours) below. > **No API key?** Add `--dry-run` to any `initrunner run` command to simulate with a test model. You can follow the entire tutorial without making API calls. --- ## 1. Changelog for Slack This one needs zero setup — just point it at your existing git history. ### Run it ```bash initrunner run examples/roles/changelog-slack.yaml -p "Changelog for the last 5 commits" ``` ### Expected output The agent reads your git log, categorizes commits by conventional-commit prefix, and produces Slack `mrkdwn`: ``` *Release Notes — 2026-02-18* _Last 5 commits by 2 contributors_ *Features* • Add audio-assistant example role (`e0e7031`) *Maintenance* • Update all docs, tests, and examples to gpt-5-mini default (`7afefd5`) • Add CHANGELOG 1.0.0 section and update README version (`1bbdb49`) *Contributors*: @alice, @bob *Stats*: 5 commits · 12 files changed · +180 / −45 lines ``` Paste that directly into a Slack channel — it renders correctly because it uses Slack's `mrkdwn` syntax (`*bold*`, `_italic_`, `•` bullets) instead of Markdown. ### Try variations ```bash # Tag-based range initrunner run examples/roles/changelog-slack.yaml -p "Changelog since v1.0.0" # More commits initrunner run examples/roles/changelog-slack.yaml -p "Last 20 commits" ``` > **Under the hood:** The built-in `git_log` tool has no `ref` parameter, so range-based queries like "since v1.0.0" need `git log v1.0.0..HEAD` via the shell. That's why this template includes a `shell` tool restricted to `allowed_commands: [git]` — it can run git commands but nothing else.

--- ## 2. PR Reviewer This template reviews the diff between your current branch and `main`. We'll create a branch with a deliberately buggy file so you can see it in action. ### Setup Create a branch with a Python file containing three planted issues: ```bash git checkout -b demo-review ``` Create a file called `app.py`: ```python import os import json # unused def get_user(db, user_id): query = f"SELECT * FROM users WHERE id = {user_id}" result = db.execute(query) return result.fetchone() def process_order(order): total = order["items"][0]["price"] * order["items"][0]["qty"] return {"total": total, "status": "processed"} ``` ```bash git add app.py && git commit -m "feat: add user lookup and order processing" ``` The file has three issues: an unused `json` import, a SQL injection vulnerability in `get_user`, and a missing null check in `process_order` (crashes if `items` is empty). ### Run it ```bash initrunner run examples/roles/pr-reviewer.yaml -p "Review changes vs main" ``` ### Expected output The agent diffs your branch against `main` and produces a severity-tagged review: ```markdown ## Review: ⚠️ Request Changes **Summary**: New user lookup has a SQL injection vulnerability; order processing lacks input validation. ### Findings 🔴 **Critical** - **`app.py:6`** — SQL injection via string interpolation in query. > Use parameterized queries: > `db.execute("SELECT * FROM users WHERE id = ?", (user_id,))` 🟡 **Major** - **`app.py:10`** — `order["items"][0]` will raise `IndexError` if items is empty. > Add a guard: `if not order.get("items"): return {"total": 0, "status": "empty"}` ⚪ **Nit** - **`app.py:2`** — `json` is imported but never used. ### What's Good - Clear function signatures with descriptive parameter names --- _Files reviewed: 1 | Findings: 1 critical, 1 major, 0 minor, 1 nit_ ``` > **Under the hood:** The agent uses `git_changed_files ref="main...HEAD"` to find modified files, then `git_diff ref="main...HEAD"` to read the actual changes. Both the `git` and `filesystem` tools are set to `read_only: true` — the reviewer can never modify your code. ### Cleanup ```bash git checkout main && git branch -D demo-review ```

--- ## 3. CI Failure Explainer This template reads a CI/CD log file, finds the root failure, and explains how to fix it. We'll create a realistic build log to test with. ### Setup Create a sample build log: ```bash cat > /tmp/build.log << 'EOF' [2026-02-18T10:00:01Z] Step 1/6: Checkout repository [2026-02-18T10:00:01Z] ✓ Checked out abc1234 [2026-02-18T10:00:02Z] Step 2/6: Set up Python 3.11 [2026-02-18T10:00:05Z] ✓ Python 3.11.8 installed [2026-02-18T10:00:06Z] Step 3/6: Install dependencies [2026-02-18T10:00:07Z] Collecting numpy==1.99.0 [2026-02-18T10:00:08Z] ERROR: Could not find a version that satisfies the requirement numpy==1.99.0 [2026-02-18T10:00:08Z] ERROR: No matching distribution found for numpy==1.99.0 [2026-02-18T10:00:09Z] Step 4/6: Run tests [2026-02-18T10:00:09Z] Skipped (dependency install failed) [2026-02-18T10:00:09Z] Step 5/6: Build package [2026-02-18T10:00:09Z] Skipped (dependency install failed) [2026-02-18T10:00:09Z] Step 6/6: Upload artifacts [2026-02-18T10:00:09Z] Skipped (dependency install failed) EOF ``` ### Run it ```bash initrunner run examples/roles/ci-explainer.yaml -p "Explain the failure in /tmp/build.log" ``` ### Expected output The agent reads the log, identifies the root cause (not the cascading "Skipped" steps), and produces a structured explanation: ````markdown ## CI Failure: Dependency Issue **TL;DR**: The build fails because `numpy==1.99.0` doesn't exist — pip can't find a matching version. ### What Failed ``` ERROR: Could not find a version that satisfies the requirement numpy==1.99.0 ERROR: No matching distribution found for numpy==1.99.0 ``` ### Why It Failed The `requirements.txt` (or `pyproject.toml`) pins `numpy==1.99.0`, which has never been published. The latest stable version is 2.2.x. This is likely a typo — `1.99.0` doesn't exist in the numpy release history. ### How to Fix 1. Update the numpy version pin to a valid release: ``` numpy>=2.0,<3.0 ``` 2. Re-run the pipeline. --- _Stage: install | File: `requirements.txt`_ ```` > **Under the hood:** The `filesystem` tool uses `root_path: /` so it can read logs anywhere on disk (e.g. `/tmp`). An `allowed_extensions` allowlist restricts it to log, config, and source files — it can't read arbitrary binary files. The `temperature: 0.0` setting ensures precise, deterministic analysis. ### Cleanup ```bash rm /tmp/build.log ```

--- ## Make Them Yours All three templates share the same customization surface. Copy one and edit: ```bash cp examples/roles/pr-reviewer.yaml my-reviewer.yaml ``` **Swap the model** — any supported provider works: ```yaml model: provider: anthropic name: claude-sonnet-4-20250514 temperature: 0.1 max_tokens: 4096 ``` See [Provider Configuration](/docs/providers) for all options including Google, Ollama, and others. **Tune guardrails** for your repo size: ```yaml guardrails: max_tool_calls: 50 # increase for large PRs with many files timeout_seconds: 600 # increase for slow models or big repos ``` **Edit the system prompt** — `spec.role` is free-text. Quick tweaks: - Focus on security: add "Focus exclusively on security vulnerabilities. Ignore style and formatting issues." - Match your stack: add "This is a Django project using PostgreSQL. Flag Django-specific anti-patterns." - Change output language: add "Write all output in Japanese." Then run your copy: ```bash initrunner run my-reviewer.yaml -p "Review changes vs main" ``` --- ## Tips **Pipe output to clipboard** for instant pasting: ```bash # macOS initrunner run examples/roles/changelog-slack.yaml -p "Last 10 commits" 2>/dev/null | pbcopy # Linux (X11) initrunner run examples/roles/changelog-slack.yaml -p "Last 10 commits" 2>/dev/null | xclip -selection clipboard # Linux (Wayland) initrunner run examples/roles/changelog-slack.yaml -p "Last 10 commits" 2>/dev/null | wl-copy ``` The `2>/dev/null` strips stderr (progress messages) so only the agent's output reaches the clipboard. **Shell aliases** for frequent use: ```bash alias pr-review='initrunner run examples/roles/pr-reviewer.yaml -p' alias changelog='initrunner run examples/roles/changelog-slack.yaml -p' alias ci-explain='initrunner run examples/roles/ci-explainer.yaml -p' # Then: pr-review "Review changes vs main" changelog "Changelog since v1.0.0" ci-explain "Explain /tmp/build.log" ``` **Dry-run for testing** — validate your YAML and prompt without API calls: ```bash initrunner run my-reviewer.yaml -p "Review changes vs main" --dry-run ``` --- ## What's Next - [Examples Reference](/docs/examples) — full configuration details and output format specs for all three templates - [Site Monitor Tutorial](/docs/tutorial) — build an agent from scratch across 7 steps (tools, memory, RAG, triggers) - [Creating Tools](/docs/tools) — add custom tools to any agent - [Provider Configuration](/docs/providers) — use Anthropic, Google, Ollama, or other providers - [Compose Orchestration](/docs/compose) — chain multiple agents together ## Core Concepts ### Concepts & Architecture # Concepts & Architecture This page gives you a mental model of how InitRunner works before you dive into specific features. ## The Role File Every InitRunner agent starts with a **role file** — a single YAML document that describes what the agent is, what it can do, and how it should behave. The format follows a Kubernetes-style structure: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: my-agent description: What this agent does tags: [category, purpose] spec: role: | System prompt goes here. model: provider: openai name: gpt-4o-mini tools: [...] memory: { ... } ingest: { ... } triggers: [...] sinks: [...] autonomy: { ... } guardrails: { ... } ``` | Section | Purpose | |---------|---------| | `metadata` | Identity — name, description, tags | | `spec.role` | System prompt — the agent's personality and instructions | | `spec.model` | Which LLM provider and model to use | | `spec.tools` | Capabilities the agent can invoke | | `spec.memory` | Session persistence and long-term memory (semantic, episodic, procedural) | | `spec.ingest` | Document ingestion and RAG settings | | `spec.triggers` | Events that start agent runs (cron, file watch, webhook, Telegram, Discord) | | `spec.sinks` | Where output goes (Slack, email, file, delegate) | | `spec.autonomy` | Plan-execute-adapt loop settings | | `spec.guardrails` | Safety limits (tokens, tools, timeouts) | Everything except `metadata` and `spec.role` is optional — a minimal agent only needs a name and a system prompt. ## Architecture Overview ```mermaid flowchart LR subgraph Input R[role.yaml] CLI[CLI / REPL] T[Triggers] end subgraph Runtime P[Parser] --> PR[LLM Adapter] PR --> A[Agent] A --> Tools[Tools] A --> M[Memory] A --> RAG[RAG / Ingestion] end subgraph Output S[Sinks] AU[Audit Log] RES[Response] end R --> P CLI --> P T --> P A --> S A --> AU A --> RES ``` **Input** — An agent run is initiated by one of three paths: loading a role file directly, interactive CLI input, or an event trigger (cron, file watch, webhook, Telegram, Discord). Prompts can include multimodal attachments (images, audio, video, documents) — see [Multimodal Input](/docs/multimodal). **Runtime** — The parser validates the YAML and hands it to the **LLM Adapter** — the internal client object that wraps a specific provider SDK (OpenAI, Anthropic, Google, etc.). This is distinct from the `spec.model.provider` string in your role file, which is just the name used to select the adapter. The adapter creates an agent that orchestrates tool calls, memory reads/writes, and document searches during execution. **Output** — Results flow to configured sinks (Slack, email, file, delegate to another agent), the audit log (SQLite), and back to the caller as a response. ## Core Building Blocks ### Tools Tools give agents the ability to act. InitRunner supports 18 configurable tool types plus auto-registered tools: | Category | Types | |----------|-------| | **Data** | `filesystem`, `sql`, `api`, `http` | | **Execution** | `shell`, `python`, `mcp`, `git` | | **Communication** | `slack`, `email` | | **Media** | `audio`, `web_reader`, `web_scraper` | | **Search** | `search` (DuckDuckGo web/news, requires `search` extra) | | **Time** | `datetime` | | **System** | `delegate`, `custom`, `plugin` | | **Auto-registered** | `search_documents` (via `spec.ingest`), memory tools (via `spec.memory`) | Each tool is sandboxed by the guardrails system. See [Tools](/docs/tools) for the full reference. ### Skills Skills are reusable prompt-and-tool bundles that can be attached to any agent. They let you share common capabilities (e.g., "summarize a webpage", "query a database") across multiple agents without duplicating configuration. See [Skills](/docs/skills). ### Memory InitRunner's memory system has two distinct parts: **Session persistence (short-term)** — Conversation history is saved to SQLite during REPL and daemon runs. Use `--resume` to reload the most recent session. This is not a "memory type" — it's automatic when `spec.memory` is configured and is always available. **Long-term memory types** — Three typed stores backed by vector embeddings: - **Semantic** — Facts and knowledge. The agent stores and retrieves these explicitly via `remember()` and `recall()`. - **Episodic** — Records of what happened during tasks — outcomes, decisions, errors. Auto-captured in autonomous and daemon modes, or written explicitly via `record_episode()`. - **Procedural** — Learned policies and patterns, stored via `learn_procedure()` and auto-injected into the system prompt on every run. Automatic consolidation extracts durable semantic facts from episodic records using an LLM. See [Memory](/docs/memory). ### Ingestion & RAG The ingestion pipeline converts documents into searchable vector embeddings: 1. Glob source files 2. Extract text (Markdown, PDF, DOCX, CSV, HTML, JSON) 3. Chunk into overlapping segments 4. Embed with a provider model 5. Store in SQLite (Zvec) At runtime, the auto-registered `search_documents` tool performs similarity search against the stored vectors. See [Ingestion](/docs/ingestion). ## Execution Lifecycle ```mermaid sequenceDiagram participant User participant CLI participant Runtime participant LLM participant Tools participant Memory participant Audit User->>CLI: initrunner run role.yaml -p "..." CLI->>Runtime: Parse YAML + prompt Runtime->>LLM: Send system prompt + user message LLM->>Runtime: Response (may include tool calls) loop Tool execution loop Runtime->>Tools: Execute tool call Tools->>Runtime: Tool result Runtime->>Memory: Store interaction Runtime->>Audit: Log action Runtime->>LLM: Send tool result LLM->>Runtime: Next response end Runtime->>User: Final response ``` 1. The user invokes the CLI with a role file and a prompt. 2. The runtime parses the YAML, resolves the provider, and sends the system prompt + user message to the LLM. If the prompt includes attachments, they are resolved (local files are read, URLs are fetched) and sent as multimodal content parts. 3. The LLM responds — possibly requesting tool calls. 4. The runtime executes each tool, logs the action to the audit database, updates memory, and feeds the result back to the LLM. 5. This loop continues until the LLM produces a final response (or a guardrail limit is hit). 6. The final response is returned to the user and sent to any configured sinks. ## Execution Modes InitRunner supports several execution modes for different use cases: | Mode | Command | Description | |------|---------|-------------| | **Chat** | `initrunner chat [role.yaml]` | Zero-config REPL, role-based chat, or one-command bot launcher ([Chat](/docs/chat)) | | **Single-shot** | `initrunner run role.yaml -p "..."` | One prompt in, one response out | | **REPL** | `initrunner run role.yaml -i` | Interactive conversation loop | | **Autonomous** | `initrunner run role.yaml -a -p "..."` | Plan-execute-adapt loop without human input ([Autonomy](/docs/autonomy)) | | **Daemon** | `initrunner daemon role.yaml` | Long-running process that listens for triggers ([Triggers](/docs/triggers)) | | **Team** | `initrunner run team.yaml --task "..."` | Sequential multi-persona collaboration ([Team Mode](/docs/team-mode)) | | **Compose** | `initrunner compose up compose.yaml` | Multi-agent orchestration ([Compose](/docs/compose)) | | **Server** | `initrunner serve role.yaml` | OpenAI-compatible HTTP API ([Server](/docs/server)) | ## Safety Layers InitRunner enforces safety at multiple levels: - **[Guardrails](/docs/guardrails)** — Token budgets, tool call limits, iteration caps, and timeouts. Prevents runaway agents. - **[Security](/docs/security)** — Shell command allowlists, filesystem sandboxing, confirmation prompts for destructive actions, HMAC webhook verification. - **[Audit](/docs/audit)** — Every tool call, LLM interaction, and agent run is logged to a SQLite database for inspection and compliance. These layers work together so you can give agents powerful tools while keeping them within safe boundaries. ### Configuration # Configuration InitRunner agents are configured through YAML role files. Every role follows the `apiVersion`/`kind`/`metadata`/`spec` structure. ## Full Schema ```yaml apiVersion: initrunner/v1 # Required — API version kind: Agent # Required — must be "Agent" metadata: name: my-agent # Required — unique agent identifier description: "" # Optional — human-readable description tags: [] # Optional — categorization tags author: "" # Optional — author name version: "" # Optional — semantic version dependencies: [] # Optional — pip dependencies spec: role: | # Required — system prompt You are a helpful assistant. model: # Model configuration provider: openai # Provider name name: gpt-4o-mini # Model identifier temperature: 0.1 # Sampling temperature (0.0-2.0) max_tokens: 4096 # Max tokens per response base_url: null # Custom endpoint URL api_key_env: null # Env var for API key output: {} # Structured output (text or json_schema) tools: [] # Tool configurations guardrails: {} # Resource limits autonomy: {} # Autonomous plan-execute-adapt loop observability: {} # OpenTelemetry tracing (opt-in) ingest: null # Document ingestion / RAG memory: null # Memory system triggers: [] # Trigger configurations sinks: [] # Output sink configurations security: null # Security policy skills: [] # Skill references resources: {} # Memory and CPU limits tool_search: {} # Tool search meta-tool config ``` ## Metadata Fields | Field | Type | Default | Description | |-------|------|---------|-------------| | `name` | `str` | *(required)* | Unique agent identifier | | `description` | `str` | `""` | Human-readable description | | `tags` | `list[str]` | `[]` | Categorization tags | | `author` | `str` | `""` | Author name | | `version` | `str` | `""` | Semantic version string | | `dependencies` | `list[str]` | `[]` | pip dependencies for custom tools | ## Model Configuration | Field | Type | Default | Description | |-------|------|---------|-------------| | `provider` | `str` | `"openai"` | Provider name (`openai`, `anthropic`, `google`, `groq`, `mistral`, `ollama`, `cohere`, `bedrock`, `xai`) | | `name` | `str` | `"gpt-4o-mini"` | Model identifier | | `base_url` | `str \| null` | `null` | Custom endpoint URL (enables OpenAI-compatible mode) | | `api_key_env` | `str \| null` | `null` | Environment variable containing the API key | | `temperature` | `float` | `0.1` | Sampling temperature (0.0-2.0) | | `max_tokens` | `int` | `4096` | Maximum tokens per response (1-128000) | See [Providers](/docs/providers) for provider-specific setup and Ollama/OpenRouter configuration. ## Guardrails | Field | Type | Default | Description | |-------|------|---------|-------------| | `max_tokens_per_run` | `int` | `50000` | Maximum output tokens consumed per agent run | | `max_tool_calls` | `int` | `20` | Maximum tool invocations per run | | `timeout_seconds` | `int` | `300` | Wall-clock timeout per run | | `max_request_limit` | `int \| null` | `auto` | Maximum LLM API round-trips per run.

Pass `--sense` and describe your task — InitRunner scores every role in your library and runs the best match automatically. ```bash initrunner run --sense -p "analyze this CSV and find trends" [sense] Scanning ./roles/, ~/.config/initrunner/roles/ [sense] Scored 4 candidates [sense] Selected: csv-analyst (score 0.87, gap +0.41) Agent: csv-analyst Running... ``` ## Why It Exists As your role library grows, remembering which file to pass to `initrunner run` becomes friction. Intent sensing removes that friction: describe the task in plain language and the right agent finds itself. ## The Two-Pass Algorithm Sensing runs in two passes: 1. **Keyword scoring** — Each role's metadata is tokenized and scored against the prompt. Scores are weighted by field: | Field | Weight | |-------|--------| | `metadata.tags` | 3× | | `metadata.name` | 2× | | `metadata.description` | 1.5× | 2. **LLM tiebreaker** — If the top two candidates are within the gap threshold of each other, InitRunner calls a small LLM (controlled by `INITRUNNER_DEFAULT_MODEL`) with the prompt and the candidates' metadata to break the tie. ## Selection Thresholds A role is auto-selected when both conditions are met: | Condition | Threshold | |-----------|-----------| | Winning score | ≥ 0.35 | | Gap above second-best | ≥ 0.15 | If neither condition is met, InitRunner prints the top candidates and exits with a prompt to specify a role explicitly or use `--confirm-role`. ## CLI Flags | Flag | Description | |------|-------------| | `--sense` | Enable intent sensing — no role file argument needed | | `--role-dir PATH` | Additional directory to scan for roles (repeatable) | | `--confirm-role` | Prompt for confirmation before running the selected role | These flags are used with `initrunner run`: ```bash # Basic usage initrunner run --sense -p "summarize last week's sales report" # Add an extra role directory initrunner run --sense --role-dir ~/work/roles -p "draft a cold outreach email" # Always confirm before running initrunner run --sense --confirm-role -p "clean up the CSV headers" ``` ## Dry Run (Keyword-Only Mode) Passing `--dry-run` alongside `--sense` disables the LLM tiebreaker. Scoring is keyword-only and no API calls are made. Useful for debugging which role would be selected without spending tokens: ```bash initrunner run --sense --dry-run -p "analyze CSV trends" ``` ## Role Discovery Order InitRunner searches for roles in this order: 1. `./roles/` — roles directory next to the current working directory 2. `~/.config/initrunner/roles/` — user-level role store 3. Any paths added with `--role-dir` Directories are scanned recursively for `*.yaml` files with `kind: Agent`. ## Writing Roles That Sense Well The `metadata.tags` field carries the most weight (3×). Keep tags specific and task-oriented: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: csv-analyst description: Analyze CSV files, summarize data, and find trends tags: - csv - data-analysis - trends - spreadsheet - tabular ``` **Tagging guide:** - Use nouns and verbs that match how you'd naturally describe the task (`summarize`, `analyze`, `email`, `draft`, `search`) - Include the data format if relevant (`csv`, `pdf`, `json`, `markdown`) - Add domain terms (`sales`, `support`, `research`, `code`) - Avoid generic tags like `agent` or `assistant` — they add noise without signal - Aim for 4–8 tags per role A well-tagged role will win cleanly (gap ≥ 0.15) without needing the LLM tiebreaker. ## Tiebreaker Model The LLM tiebreaker uses the model set in the `INITRUNNER_DEFAULT_MODEL` environment variable: ```bash export INITRUNNER_DEFAULT_MODEL=openai:gpt-4o-mini ``` Or, to persist across sessions, add it to `~/.initrunner/.env`: ```dotenv INITRUNNER_DEFAULT_MODEL=openai:gpt-4o-mini ``` If unset, it falls back to `openai:gpt-4o-mini`. The tiebreaker call is a single low-token request — typically under 200 tokens — and only fires when the top two candidates are too close to separate by keyword score alone. ### Providers # Providers The default model is `openai`/`gpt-4o-mini`. Switch to any supported provider, a local Ollama instance, or a custom OpenAI-compatible endpoint by changing the `spec.model` block. ## Standard Providers | Provider | Env Var | Extra to install | Example model | |----------|---------|-----------------|---------------| | `openai` | `OPENAI_API_KEY` | *(included)* | `gpt-4o-mini` | | `anthropic` | `ANTHROPIC_API_KEY` | `initrunner[anthropic]` | `claude-sonnet-4-20250514` | | `google` | `GOOGLE_API_KEY` | `initrunner[google]` | `gemini-2.0-flash` | | `groq` | `GROQ_API_KEY` | `initrunner[groq]` | `llama-3.3-70b-versatile` | | `mistral` | `MISTRAL_API_KEY` | `initrunner[mistral]` | `mistral-large-latest` | | `cohere` | `CO_API_KEY` | `initrunner[all-models]` | `command-r-plus` | | `bedrock` | `AWS_ACCESS_KEY_ID` | `initrunner[all-models]` | `us.anthropic.claude-sonnet-4-20250514-v1:0` | | `xai` | `XAI_API_KEY` | `initrunner[all-models]` | `grok-3` | Install all provider extras at once: ```bash pip install initrunner[all-models] ``` ### Example ```yaml spec: model: provider: anthropic name: claude-sonnet-4-20250514 ``` ### Provider Snippets **OpenAI** (no extra required): ```yaml spec: model: provider: openai name: gpt-4o-mini ``` **Anthropic** (`pip install initrunner[anthropic]`): ```yaml spec: model: provider: anthropic name: claude-sonnet-4-5-20250929 ``` **Google** (`pip install initrunner[google]`): ```yaml spec: model: provider: google name: gemini-2.0-flash ``` **Groq** (`pip install initrunner[groq]`): ```yaml spec: model: provider: groq name: llama-3.3-70b-versatile ``` **Mistral** (`pip install initrunner[mistral]`): ```yaml spec: model: provider: mistral name: mistral-large-latest ``` **Cohere** (`pip install initrunner[all-models]`): ```yaml spec: model: provider: cohere name: command-r-plus ``` **Bedrock** (`pip install initrunner[all-models]`): ```yaml spec: model: provider: bedrock name: us.anthropic.claude-sonnet-4-20250514-v1:0 ``` **xAI** (`pip install initrunner[all-models]`): ```yaml spec: model: provider: xai name: grok-3 ``` ## Model Selection `PROVIDER_MODELS` in `templates.py` maintains curated model lists for each provider. The interactive wizard (`initrunner init -i`) and setup command (`initrunner setup`) present these as a numbered menu. The `--model` flag on `init`, `setup`, and `create` bypasses the interactive prompt. Custom model names are always accepted — the curated list is a convenience, not a restriction. | Provider | Model | Description | |----------|-------|-------------| | `openai` | **`gpt-4o-mini`** | Fast, affordable (default) | | `openai` | `gpt-4o` | High capability GPT-4 | | `openai` | `gpt-4.1` | Latest GPT-4.1 | | `openai` | `gpt-4.1-mini` | Small GPT-4.1 | | `openai` | `gpt-4.1-nano` | Fastest GPT-4.1 | | `openai` | `o3-mini` | Reasoning model | | `anthropic` | **`claude-sonnet-4-5-20250929`** | Balanced, fast (default) | | `anthropic` | `claude-haiku-35-20241022` | Compact, very fast | | `anthropic` | `claude-opus-4-20250514` | Most capable | | `google` | **`gemini-2.0-flash`** | Fast multimodal (default) | | `google` | `gemini-2.5-pro-preview-05-06` | Most capable | | `google` | `gemini-2.0-flash-lite` | Lightweight | | `groq` | **`llama-3.3-70b-versatile`** | Fast Llama 70B (default) | | `groq` | `llama-3.1-8b-instant` | Ultra-fast 8B | | `groq` | `mixtral-8x7b-32768` | Mixtral MoE | | `mistral` | **`mistral-large-latest`** | Most capable (default) | | `mistral` | `mistral-small-latest` | Fast, efficient | | `mistral` | `codestral-latest` | Code-optimized | | `cohere` | **`command-r-plus`** | Advanced RAG (default) | | `cohere` | `command-r` | Balanced | | `cohere` | `command-light` | Fast | | `bedrock` | **`us.anthropic.claude-sonnet-4-20250514-v1:0`** | Claude Sonnet via Bedrock (default) | | `bedrock` | `us.anthropic.claude-haiku-4-20250514-v1:0` | Claude Haiku via Bedrock | | `bedrock` | `us.meta.llama3-2-90b-instruct-v1:0` | Llama 3.2 90B via Bedrock | | `xai` | **`grok-3`** | Most capable Grok (default) | | `xai` | `grok-3-mini` | Fast Grok | | `ollama` | **`llama3.2`** | Llama 3.2 (default) | | `ollama` | `llama3.1` | Llama 3.1 | | `ollama` | `mistral` | Mistral 7B | | `ollama` | `codellama` | Code Llama | | `ollama` | `phi3` | Microsoft Phi-3 | For Ollama, the wizard also queries the local Ollama server for installed models and shows those if available. ## Ollama (Local Models) Set `provider: ollama`. No API key is needed — the runner defaults to `http://localhost:11434/v1`: ```yaml spec: model: provider: ollama name: llama3.2 ``` Override the URL if Ollama is on a different host or port: ```yaml spec: model: provider: ollama name: llama3.2 base_url: http://192.168.1.50:11434/v1 ``` > **Docker note:** If the runner is inside Docker and Ollama is on the host, use `http://host.docker.internal:11434/v1` as the `base_url`. ## OpenRouter / Custom Endpoints Any OpenAI-compatible API works. Set `provider: openai`, point `base_url` at the endpoint, and specify which env var holds the API key: ```yaml spec: model: provider: openai name: anthropic/claude-sonnet-4 base_url: https://openrouter.ai/api/v1 api_key_env: OPENROUTER_API_KEY ``` This also works for vLLM, LiteLLM, Azure OpenAI, or any other service that exposes the OpenAI chat completions format. ## Model Config Reference | Field | Type | Default | Description | |-------|------|---------|-------------| | `provider` | `str` | `"openai"` | Provider name (`openai`, `anthropic`, `google`, `groq`, `mistral`, `cohere`, `bedrock`, `xai`, `ollama`) | | `name` | `str` | `"gpt-4o-mini"` | Model identifier | | `base_url` | `str \| null` | `null` | Custom endpoint URL (triggers OpenAI-compatible mode) | | `api_key_env` | `str \| null` | `null` | Environment variable containing the API key | | `temperature` | `float` | `0.1` | Sampling temperature (0.0-2.0) | | `max_tokens` | `int` | `4096` | Maximum tokens per response (1-128000) | ## Embedding Configuration for RAG When an agent uses RAG or memory, InitRunner needs an embedding model to convert text into vectors. The embedding provider is chosen automatically based on `spec.model.provider`, but can be overridden. ### Default Embedding Model by Provider | Agent provider | Default embedding model | |----------------|------------------------| | `openai` | `openai:text-embedding-3-small` | | `anthropic` | `openai:text-embedding-3-small` | | `google` | `google:text-embedding-004` | | `ollama` | `ollama:nomic-embed-text` | > **Anthropic users:** Anthropic does not offer an embeddings API. If your agent uses RAG or memory, InitRunner falls back to OpenAI embeddings by default — which means you also need `OPENAI_API_KEY` set. Pure chat agents without `spec.ingest` or `spec.memory` do **not** need it. To avoid the OpenAI dependency entirely, use Ollama embeddings instead. ### Overriding the Embedding Model Set `spec.ingest.embeddings` to use any supported provider and model: ```yaml spec: model: provider: anthropic name: claude-sonnet-4-5-20250929 ingest: sources: - "./docs/**/*.md" embeddings: provider: ollama model: nomic-embed-text base_url: http://localhost:11434/v1 # optional api_key_env: MY_EMBED_KEY # optional ``` | Field | Description | |-------|-------------| | `provider` | Embedding provider (`openai`, `google`, `ollama`) | | `model` | Embedding model identifier | | `base_url` | Custom endpoint (useful for Ollama on a non-default port) | | `api_key_env` | Environment variable holding the API key | ## Full Role Example ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: support-agent description: Answers questions from the support knowledge base tags: - support - rag spec: role: | You are a support agent. Use search_documents to find relevant articles before answering.

This requires **zero additional dependencies** — it reuses the `openai` SDK already bundled with the core install. ## Quick Start 1. Install and start Ollama: ```bash # macOS / Linux curl -fsSL https://ollama.com/install.sh | sh ollama serve ``` 2. Pull a model: ```bash ollama pull llama3.2 ``` 3. Scaffold a role: ```bash initrunner init --template ollama --name my-local-agent --model llama3.2 ``` 4. Run the agent: ```bash initrunner run role.yaml -i ``` ## How It Works Ollama exposes an OpenAI-compatible API at `http://localhost:11434/v1`. When `provider: ollama` is set (or a `base_url` is specified), InitRunner constructs a PydanticAI `OpenAIProvider` with that endpoint instead of calling the real OpenAI API. A dummy API key (`"ollama"`) is set automatically so the SDK doesn't look for `OPENAI_API_KEY` in the environment. ## Configuration ### Minimal Ollama Role ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: local-agent description: Agent using local Ollama model spec: role: | You are a helpful assistant. model: provider: ollama name: llama3.2 # Run: ollama pull llama3.2 ``` ### Model Config Reference ```yaml spec: model: provider: ollama # required — triggers local model setup name: llama3.2 # required — model name as known to Ollama base_url: http://localhost:11434/v1 # default for ollama; override for remote temperature: 0.1 # default: 0.1 max_tokens: 4096 # default: 4096 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `provider` | `str` | — | Set to `"ollama"` for local Ollama models | | `name` | `str` | — | Model name (e.g. `llama3.2`, `mistral`, `codellama`) | | `base_url` | `str \| null` | `null` | Custom endpoint URL. Defaults to `http://localhost:11434/v1` when provider is `ollama`. | | `temperature` | `float` | `0.1` | Sampling temperature (0.0–2.0) | | `max_tokens` | `int` | `4096` | Maximum tokens per response (1–128000) | ## Custom OpenAI-Compatible Endpoints The `base_url` field works with any provider, not just Ollama. Use it to point at vLLM, LiteLLM, llama.cpp, or any other server that exposes an OpenAI-compatible API: ```yaml spec: model: provider: openai name: my-model base_url: http://my-server:8000/v1 ``` When `base_url` is set on a non-ollama provider, the API key is set to `"custom-provider"` to avoid environment variable lookups. If your endpoint requires authentication, set `OPENAI_API_KEY` in the environment and omit `base_url` (use the standard `openai` provider flow). ## Embeddings Ollama also serves embeddings. When using ingestion or memory with Ollama, configure the embedding model in the `embeddings` section: ```yaml spec: model: provider: ollama name: llama3.2 ingest: sources: - "./docs/**/*.md" embeddings: provider: ollama model: nomic-embed-text # Run: ollama pull nomic-embed-text # base_url: http://localhost:11434/v1 # default ``` ### Embedding Config Reference | Field | Type | Default | Description | |-------|------|---------|-------------| | `provider` | `str` | `""` | Embedding provider. Set to `"ollama"` for local embeddings. Empty inherits from `spec.model.provider`. | | `model` | `str` | `""` | Embedding model name. Empty uses provider default (`nomic-embed-text` for Ollama). | | `base_url` | `str` | `""` | Custom endpoint URL. Defaults to `http://localhost:11434/v1` when provider is `ollama`. | | `api_key_env` | `str` | `""` | Env var name holding the embedding API key. Not needed for Ollama. | ### Default Embedding Models | Provider | Default Model | |----------|--------------| | `openai` | `text-embedding-3-small` | | `ollama` | `nomic-embed-text` | | `google` | `text-embedding-004` | | `anthropic` | `text-embedding-3-small` (uses OpenAI) | ## Example: Local RAG Agent Full local RAG stack — no external API calls or API keys: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: local-rag description: Local RAG agent with Ollama tags: - rag - ollama spec: role: | You are a knowledge assistant. Use search_documents to find relevant content before answering. Always cite your sources. model: provider: ollama name: llama3.2 ingest: sources: - "./docs/**/*.md" - "./docs/**/*.txt" chunking: strategy: fixed chunk_size: 512 chunk_overlap: 50 embeddings: provider: ollama model: nomic-embed-text ``` ```bash ollama pull llama3.2 ollama pull nomic-embed-text initrunner ingest role.yaml initrunner run role.yaml -i ``` ## Example: Memory Agent Long-term memory works fully offline with Ollama: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: local-memory description: Local agent with memory spec: role: | You are a helpful assistant with long-term memory. Use remember() to save important information. Use recall() to search your memories. model: provider: ollama name: llama3.2 memory: max_sessions: 10 max_memories: 1000 embeddings: provider: ollama model: nomic-embed-text ``` ## Docker When running InitRunner inside Docker, `localhost` won't reach the host machine. Use `host.docker.internal` instead: ```yaml spec: model: provider: ollama name: llama3.2 base_url: http://host.docker.internal:11434/v1 ``` InitRunner automatically detects Docker environments (via `/.dockerenv`) and logs a warning if `base_url` contains `localhost` or `127.0.0.1`. Alternatively, run Ollama in the same Docker network: ```yaml # docker-compose.yml services: ollama: image: ollama/ollama ports: - "11434:11434" agent: build: . environment: - OLLAMA_HOST=http://ollama:11434/v1 ``` ```yaml spec: model: provider: ollama name: llama3.2 base_url: http://ollama:11434/v1 ``` ## CLI ### Scaffold an Ollama Role ```bash initrunner init --template ollama --name my-agent --model mistral ``` This generates a `role.yaml` pre-configured for `provider: ollama` with the specified model (or `llama3.2` by default). After scaffolding, InitRunner pings `http://localhost:11434/api/tags` and prints a warning if Ollama is not reachable. ### Available Templates Any template works with `--provider ollama`: ```bash initrunner init --template basic --provider ollama --model codellama initrunner init --template rag --provider ollama --model llama3.2 initrunner init --template memory --provider ollama initrunner init --template daemon --provider ollama initrunner init --template ollama # dedicated template with Ollama-specific comments ``` ## Troubleshooting ### "Ollama does not appear to be running" Start the Ollama server: ```bash ollama serve ``` On macOS, you can also launch the Ollama desktop app. ### Connection refused at runtime Verify Ollama is running and accessible: ```bash curl http://localhost:11434/api/tags ``` If using a remote Ollama instance, set `base_url` explicitly: ```yaml spec: model: provider: ollama name: llama3.2 base_url: http://remote-host:11434/v1 ``` ### Model not found Pull the model before running: ```bash ollama pull llama3.2 ``` List available models: ```bash ollama list ``` ### Slow responses Local models are limited by your hardware. Tips: - Use smaller models (`llama3.2` 3B is faster than `llama3.1` 70B) - Increase `timeout_seconds` in guardrails for larger models - Use GPU acceleration (Ollama auto-detects CUDA/Metal) ### EmbeddingModelChangedError on ingestion You switched embedding models. The CLI will prompt you to confirm wiping the store and re-ingesting. To skip the prompt, use `--force`: ```bash initrunner ingest role.yaml --force ``` ## Popular Ollama Models | Model | Size | Good For | |-------|------|----------| | `llama3.2` | 3B | General purpose, fast | | `llama3.1` | 8B/70B | Higher quality, slower | | `mistral` | 7B | Balanced performance | | `codellama` | 7B/13B | Code generation | | `nomic-embed-text` | 137M | Embeddings (for RAG/memory) | | `mxbai-embed-large` | 335M | Higher-quality embeddings | ## Agent Capabilities ### Tools # Tools Tools give agents the ability to interact with the outside world — reading files, making HTTP requests, connecting to MCP servers, calling APIs, or running custom Python functions. They are configured in the `spec.tools` list, keyed on the `type` field. ## Tool Types | Type | Description | |------|-------------| | `filesystem` | Read/write files within a sandboxed root directory | | `http` | Make HTTP requests to a base URL | | `mcp` | Connect to MCP servers (stdio, SSE, streamable-http) | | `custom` | Load Python functions from a module | | `delegate` | Invoke other agents as tool calls | | `api` | Declarative REST API endpoints defined in YAML | | `web_reader` | Fetch web pages and convert to markdown | | `python` | Execute Python code in a subprocess | | `datetime` | Get current time and parse dates | | `sql` | Query SQLite databases (read-only) | | `git` | Run git operations in a subprocess | | `shell` | Execute shell commands with allowlists | | `web_scraper` | Scrape web pages and extract structured data | | `slack` | Send messages via Slack webhooks | | `search` | Web and news search via DuckDuckGo, SerpAPI, Brave, or Tavily | | `email` | Search, read, and send emails via IMAP/SMTP | | `audio` | Fetch YouTube transcripts and transcribe local audio files | | `csv_analysis` | Inspect, summarize, and query CSV files within a sandboxed root directory | | `think` | Internal reasoning scratchpad — agent thinks step-by-step without user-visible output | | `script` | Inline shell scripts defined in YAML as named, parameterized tools | | *(plugin)* | Any other type resolved via the plugin registry | ## Quick Example ```yaml spec: tools: - type: filesystem root_path: ./src read_only: true allowed_extensions: [".py", ".md"] - type: http base_url: https://api.example.com allowed_methods: ["GET", "POST"] headers: Authorization: Bearer ${API_TOKEN} - type: mcp transport: stdio command: npx args: ["-y", "@anthropic/mcp-server-filesystem"] - type: custom module: my_tools config: db_url: "postgres://..." - type: api name: weather base_url: https://api.weather.com endpoints: - name: get_weather path: "/current/{city}" parameters: - name: city type: string required: true ``` ## Tool Permissions Every built-in tool type has an optional `permissions` block on its configuration. When present, a `PermissionToolset` wrapper evaluates glob patterns against call arguments before the tool executes. When absent, no filtering is applied — existing behavior is preserved. ### Fields | Field | Type | Default | Description | |-------|------|---------|-------------| | `default` | `"allow" \| "deny"` | `"allow"` | Policy applied when no rule matches | | `allow` | `list[str]` | `[]` | Patterns that permit a call | | `deny` | `list[str]` | `[]` | Patterns that block a call | ### Pattern Format Two pattern forms are supported: - **Named argument** — `arg_name=glob_pattern` matches with `fnmatch` against a specific named argument (e.g. `command=kubectl *`). - **Bare glob** — a pattern without `=` matches against all string arguments (e.g. `*.env`). Validation rejects empty argument names and empty globs. ### Evaluation Order 1. **Deny rules** are checked first. If any deny pattern matches, the call is blocked. 2. **Allow rules** are checked next. If any allow pattern matches, the call is permitted. 3. **Default policy** is applied when no rule matches. Deny always wins — a call matching both an allow and a deny pattern is blocked. ### Examples **Shell** — deny by default, allow only safe commands: ```yaml tools: - type: shell allowed_commands: [kubectl, docker, curl] permissions: default: deny allow: - command=kubectl get * - command=kubectl describe * - command=docker ps * - command=curl https://* deny: - command=rm * ``` **Filesystem** — allow by default, block sensitive files: ```yaml tools: - type: filesystem root_path: ./project permissions: default: allow deny: - "*.env" - "*credentials*" - "*.pem" ``` **HTTP** — block internal and admin endpoints: ```yaml tools: - type: http base_url: https://api.example.com permissions: default: allow deny: - "*internal*" - "*admin*" ``` ### Denied Response Format When a call is blocked, the agent receives the message: ``` Permission denied: {tool_name} — blocked by rule: {pattern} ``` Raw argument values are never echoed in the denial message to prevent secret leakage. ## CSV Analysis Inspect, summarize, and query CSV files within a sandboxed root directory. Three sub-functions are registered automatically. ```yaml tools: - type: csv_analysis root_path: ./data max_rows: 1000 max_file_size_mb: 10.0 delimiter: "," ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `root_path` | `str` | `"."` | Root directory for CSV file access (path traversal is blocked) | | `max_rows` | `int` | `1000` | Maximum rows loaded from the CSV | | `max_file_size_mb` | `float` | `10.0` | Maximum CSV file size in MB | | `delimiter` | `str` | `","` | CSV delimiter character | Registered functions: - `inspect_csv(path)` — Returns column names, types, row count, and a sample of the first few rows. - `summarize_csv(path, column)` — Returns per-column statistics. Numeric columns: min, max, mean, median, stdev. Categorical columns: unique count and top values. - `query_csv(path, filter_column, filter_value, columns, limit)` — Filter rows by exact column=value match and return as a markdown table. ## Filesystem Sandboxed file operations within a root directory. Paths cannot escape the root (path traversal is blocked). ```yaml tools: - type: filesystem root_path: ./src read_only: true allowed_extensions: [".py", ".md", ".txt"] ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `root_path` | `str` | `"."` | Root directory for file operations | | `allowed_extensions` | `list[str]` | `[]` | File extensions to allow (empty = all) | | `read_only` | `bool` | `true` | Only allow read operations | Registered functions: `read_file(path)`, `list_directory(path)`, and `write_file(path, content)` (when `read_only: false`). ## HTTP Makes HTTP requests to a configured base URL. ```yaml tools: - type: http base_url: https://api.example.com allowed_methods: ["GET"] headers: Authorization: Bearer ${API_TOKEN} ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `base_url` | `str` | *(required)* | Base URL for requests | | `allowed_methods` | `list[str]` | `["GET"]` | Allowed HTTP methods | | `headers` | `dict` | `{}` | Headers sent with every request | Registered function: `http_request(method, path, body)`. ## MCP Connects to [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) servers, exposing their tools to the agent. ```yaml tools: # Stdio transport (local process) - type: mcp transport: stdio command: npx args: ["-y", "@anthropic/mcp-server-filesystem"] # SSE transport (remote server) - type: mcp transport: sse url: http://localhost:3001/sse # Streamable HTTP transport - type: mcp transport: streamable-http url: http://localhost:3001/mcp tool_filter: [search, get_document] ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `transport` | `str` | `"stdio"` | `"stdio"`, `"sse"`, or `"streamable-http"` | | `command` | `str \| null` | `null` | Command for stdio transport | | `args` | `list[str]` | `[]` | Arguments for the stdio command | | `url` | `str \| null` | `null` | URL for SSE or streamable-http transport | | `tool_filter` | `list[str]` | `[]` | Only expose these tools (empty = all; mutually exclusive with `tool_exclude`) | | `tool_exclude` | `list[str]` | `[]` | Exclude these tools (mutually exclusive with `tool_filter`) | | `headers` | `dict` | `{}` | HTTP headers for SSE/streamable-http transport | | `env` | `dict` | `{}` | Environment variables passed to the stdio subprocess | | `cwd` | `str \| null` | `null` | Working directory for the stdio subprocess | | `tool_prefix` | `str \| null` | `null` | Prefix added to tool names to avoid collisions | | `max_retries` | `int` | `1` | Maximum connection retry attempts | | `timeout` | `int \| null` | `null` | Connection timeout in seconds | ## Custom Load Python functions from a module and register them as agent tools. ```yaml tools: # Auto-discover all public functions - type: custom module: my_tools # Load a single function - type: custom module: my_tools function: search_db # With config injection - type: custom module: my_tools config: api_key: ${MY_API_KEY} ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `module` | `str` | *(required)* | Python module path (must be importable) | | `function` | `str \| null` | `null` | Specific function to load (`null` = auto-discover all) | | `config` | `dict` | `{}` | Config injected into functions with a `tool_config` parameter | Functions that declare a `tool_config` parameter receive the config dict automatically — the parameter is hidden from the LLM. Scaffold a tool module: ```bash initrunner init --template tool --name my_tools ``` ### Complete Custom Tool Walkthrough Here's a full example with the Python module and the role YAML that uses it. **`my_tools.py`** — every public function becomes an agent tool: ```python """Custom tools module for InitRunner.

Use these tools to help the user with practical tasks. Available custom tools: - convert_units: Convert between common measurement units - generate_uuid: Generate a random UUID v4 identifier - format_json: Pretty-print a JSON string - word_count: Count words, characters, and lines in text - hash_text: Hash text with md5, sha1, sha256, or sha512 - lookup_with_config: Look up a query using the configured prefix and source Always use the appropriate tool rather than trying to compute results yourself. model: provider: openai name: gpt-4o-mini temperature: 0.1 tools: - type: custom module: my_tools config: prefix: "DEMO" source: "custom-tools-demo" - type: datetime guardrails: max_tokens_per_run: 20000 max_tool_calls: 15 timeout_seconds: 60 ``` Run from the directory containing both files: ```bash cd examples/roles/custom-tools-demo initrunner run custom-tools-demo.yaml -i ``` Example prompts: ``` > Convert 72 degrees Fahrenheit to Celsius > Generate a UUID for me > Hash "hello world" with sha256 > Look up "test query" ``` > **Key patterns:** Docstrings become tool descriptions. Type annotations become parameter schemas. The `tool_config` parameter is injected from the YAML `config` block and hidden from the LLM — the agent never sees `prefix` or `source` as callable parameters. Omitting `function` in the YAML auto-discovers all public functions in the module. ## API Declarative REST API endpoints defined entirely in YAML — no Python required. ```yaml tools: - type: api name: github description: GitHub REST API base_url: https://api.github.com headers: Accept: application/vnd.github.v3+json auth: Authorization: "Bearer ${GITHUB_TOKEN}" endpoints: - name: get_repo method: GET path: "/repos/{owner}/{repo}" description: Get repository information parameters: - name: owner type: string required: true - name: repo type: string required: true response_extract: "$.full_name" - name: create_issue method: POST path: "/repos/{owner}/{repo}/issues" description: Create a new issue parameters: - name: owner type: string required: true - name: repo type: string required: true - name: title type: string required: true - name: body type: string required: false default: "" body_template: title: "{title}" body: "{body}" response_extract: "$.html_url" ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `name` | `str` | *(required)* | API group name | | `base_url` | `str` | *(required)* | Base URL for all endpoints | | `headers` | `dict` | `{}` | Headers sent with every request (supports `${VAR}`) | | `auth` | `dict` | `{}` | Auth headers merged into `headers` | | `endpoints` | `list` | *(required)* | Endpoint definitions | Each endpoint supports `name`, `method`, `path`, `description`, `parameters`, `headers`, `body_template`, `query_params`, `response_extract`, and `timeout`. Scaffold an API tool agent: ```bash initrunner init --template api --name weather-agent ``` ## Delegate Invoke other agents as tool calls. Each agent reference generates a `delegate_to_{name}` tool. ```yaml tools: - type: delegate agents: - name: summarizer role_file: ./roles/summarizer.yaml description: "Summarizes long text" - name: researcher role_file: ./roles/researcher.yaml description: "Researches topics" mode: inline max_depth: 3 timeout_seconds: 120 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `agents` | `list` | *(required)* | Agent references (`name` + `role_file` or `url`) | | `mode` | `str` | `"inline"` | `"inline"` (in-process) or `"mcp"` (HTTP) | | `max_depth` | `int` | `3` | Maximum delegation recursion depth | | `timeout_seconds` | `int` | `120` | Timeout per delegation call | | `shared_memory` | `object \| null` | `null` | Shared memory config with `store_path` (str) and `max_memories` (int, default 1000) | ## Git Subprocess-based git operations with read-only default. ```yaml tools: - type: git repo_path: . read_only: true timeout_seconds: 30 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `repo_path` | `str` | `"."` | Path to the git repository | | `read_only` | `bool` | `true` | Only allow read operations | | `timeout_seconds` | `int` | `30` | Timeout for each git command | Read tools: `git_status`, `git_log`, `git_diff`, `git_show`, `git_blame`, `git_changed_files`, `git_list_files`. Write tools (when `read_only: false`): `git_checkout`, `git_commit`, `git_tag`. ## Shell Execute shell commands with an allowlist. ```yaml tools: - type: shell allowed_commands: [kubectl, docker, curl] require_confirmation: false timeout_seconds: 30 working_dir: . ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `allowed_commands` | `list[str]` | `[]` | Allowlist of executable names; empty = all non-blocked commands are permitted | | `blocked_commands` | `list[str]` | *(built-in denylist)* | Commands always blocked regardless of `allowed_commands` (e.g. `rm`, `sudo`) | | `require_confirmation` | `bool` | `true` | Prompt user before each execution | | `timeout_seconds` | `int` | `30` | Timeout per command in seconds | | `working_dir` | `str \| null` | `null` | Working directory (`null` = role file's directory) | | `max_output_bytes` | `int` | `102400` | Truncate combined stdout+stderr beyond this byte count | Registered function: `run_shell(command)`. Shell operators (`|`, `&&`, `;`, redirects) are blocked — use dedicated tools instead. When `allowed_commands` is empty, all non-blocked commands are permitted; when non-empty, only listed executables are allowed. > When [`security.docker`](/docs/docker-sandbox) is enabled, commands run inside Docker containers instead of the host. ## Web Reader Fetch a web page and return its content as markdown. Internal (SSRF) addresses are automatically blocked. ```yaml tools: - type: web_reader allowed_domains: [] timeout_seconds: 15 max_content_bytes: 512000 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `allowed_domains` | `list[str]` | `[]` | Only fetch from these domains (empty = allow all) | | `blocked_domains` | `list[str]` | `[]` | Never fetch from these domains (ignored when `allowed_domains` is set) | | `max_content_bytes` | `int` | `512000` | Truncate page content beyond this byte count | | `timeout_seconds` | `int` | `15` | HTTP request timeout in seconds | | `user_agent` | `str` | *(default)* | `User-Agent` header sent with requests | Registered function: `fetch_page(url)`. ## Python Execute Python code in a subprocess with optional network isolation. ```yaml tools: - type: python timeout_seconds: 30 network_disabled: true require_confirmation: true ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `timeout_seconds` | `int` | `30` | Timeout per execution in seconds | | `max_output_bytes` | `int` | `102400` | Truncate combined stdout+stderr beyond this byte count | | `working_dir` | `str \| null` | `null` | Working directory (`null` = fresh temp directory per run) | | `require_confirmation` | `bool` | `true` | Prompt user before each execution | | `network_disabled` | `bool` | `true` | Block outbound network access via audit hook | Registered function: `run_python(code)`. > When [`security.docker`](/docs/docker-sandbox) is enabled, code runs inside Docker containers instead of the host. ## DateTime Get the current date/time and parse date strings. Requires no API key or external service. ```yaml tools: - type: datetime default_timezone: UTC ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `default_timezone` | `str` | `"UTC"` | Default timezone when none is specified in the tool call | Registered functions: `current_time(timezone)`, `parse_date(text, format)`. ## SQL Query a SQLite database. Read-only by default — `ATTACH DATABASE` is blocked at the engine level to prevent escaping the configured database. ```yaml tools: - type: sql database: ./data.db read_only: true max_rows: 100 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `database` | `str` | *(required)* | Path to the SQLite file, or `:memory:` for an in-memory database | | `read_only` | `bool` | `true` | Only allow SELECT statements | | `max_rows` | `int` | `100` | Maximum rows returned per query | | `max_result_bytes` | `int` | `102400` | Truncate result output beyond this byte count | | `timeout_seconds` | `int` | `10` | SQLite connection timeout in seconds | Registered function: `query_database(sql)`. ## Web Scraper Fetch a web page, extract its content, and store it in the document store so it becomes searchable via `search_documents`. Uses the chunking and embedding settings from `spec.ingest`. ```yaml tools: - type: web_scraper allowed_domains: [] timeout_seconds: 15 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `allowed_domains` | `list[str]` | `[]` | Only scrape these domains (empty = allow all) | | `blocked_domains` | `list[str]` | `[]` | Never scrape these domains (ignored when `allowed_domains` is set) | | `max_content_bytes` | `int` | `512000` | Truncate page content beyond this byte count | | `timeout_seconds` | `int` | `15` | HTTP request timeout in seconds | | `user_agent` | `str` | *(default)* | `User-Agent` header sent with requests | Registered function: `scrape_page(url)`. After scraping, the page is chunked and embedded using the settings from `spec.ingest`, then stored so `search_documents` can retrieve it. ## Search Web and news search via pluggable providers. The default provider (DuckDuckGo) requires no API key. ```yaml tools: - type: search provider: duckduckgo max_results: 10 safe_search: true timeout_seconds: 15 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `provider` | `str` | `"duckduckgo"` | Search backend to use | | `api_key` | `str \| null` | `null` | API key (required for paid providers) | | `max_results` | `int` | `10` | Maximum results per query | | `safe_search` | `bool` | `true` | Enable safe-search filtering | | `timeout_seconds` | `int` | `15` | Timeout for each search request | ### Providers | Provider | API key required | Notes | |----------|-----------------|-------| | `duckduckgo` | No | Free, no account needed | | `serpapi` | Yes | Google results via SerpAPI | | `brave` | Yes | Brave Search API | | `tavily` | Yes | Tavily search API | Registered functions: `web_search(query, num_results)`, `news_search(query, num_results, days_back)`. Install the search extra for the DuckDuckGo provider: ```bash pip install initrunner[search] ``` ## Email Search, read, and send emails via IMAP/SMTP. Read-only by default — sending requires explicit opt-in. ```yaml tools: - type: email imap_host: imap.gmail.com smtp_host: smtp.gmail.com imap_port: 993 smtp_port: 587 username: ${EMAIL_USER} password: ${EMAIL_PASSWORD} use_ssl: true default_folder: INBOX read_only: true max_results: 20 max_body_chars: 50000 timeout_seconds: 30 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `imap_host` | `str` | *(required)* | IMAP server hostname | | `smtp_host` | `str \| null` | `null` | SMTP server hostname (required for sending) | | `imap_port` | `int` | `993` | IMAP port | | `smtp_port` | `int` | `587` | SMTP port | | `username` | `str` | *(required)* | Email account username | | `password` | `str` | *(required)* | Email account password (supports `${VAR}`) | | `use_ssl` | `bool` | `true` | Use SSL/TLS for connections | | `default_folder` | `str` | `"INBOX"` | Default mailbox folder | | `read_only` | `bool` | `true` | Only allow read operations | | `max_results` | `int` | `20` | Maximum emails returned per search | | `max_body_chars` | `int` | `50000` | Truncate email bodies beyond this length | | `timeout_seconds` | `int` | `30` | Timeout for IMAP/SMTP operations | Registered functions: `search_inbox(query, folder, limit)`, `read_email(message_id, folder)`, `list_folders()`. When `read_only: false`, an additional function is registered: `send_email(to, subject, body, reply_to, cc)`. > **Security:** The email tool defaults to read-only mode. Use environment variables (`${EMAIL_USER}`, `${EMAIL_PASSWORD}`) for credentials — never hard-code them in YAML. ## Audio Fetch YouTube video transcripts and transcribe local audio/video files. Requires the `audio` extra (`pip install initrunner[audio]`). ```yaml tools: - type: audio youtube_languages: ["en"] include_timestamps: false transcription_model: null # defaults to spec.model max_audio_mb: 20.0 max_transcript_chars: 50000 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `youtube_languages` | `list[str]` | `["en"]` | Preferred caption language codes for YouTube transcripts | | `include_timestamps` | `bool` | `false` | Include timestamps in transcript output | | `transcription_model` | `str \| null` | `null` | Multimodal model for local transcription (e.g. `openai:gpt-4o-audio-preview`); defaults to the agent's model | | `max_audio_mb` | `float` | `20.0` | Maximum local file size to send for transcription | | `max_transcript_chars` | `int` | `50000` | Truncate transcript output beyond this length | Registered functions: `get_youtube_transcript(url, language)`, `transcribe_audio(file_path)`. Supported audio formats: `.mp3`, `.mp4`, `.m4a`, `.wav`, `.ogg`, `.webm`, `.mpeg`, `.flac`. > **Model requirement:** `transcribe_audio` passes audio to the agent's model > (or `transcription_model` if set). Use a model that supports audio input such > as `openai:gpt-4o-audio-preview`. See [Multimodal](/docs/multimodal) for > supported models. **Example — meeting notes agent:** ```yaml spec: model: provider: openai name: gpt-4o-audio-preview tools: - type: audio include_timestamps: true max_audio_mb: 25.0 ``` ## Think Tool Gives the agent an internal reasoning scratchpad. The agent can think step-by-step before acting — its thoughts are preserved in the tool call arguments but the tool returns a constant acknowledgment, so thought content does not appear in tool results, audit logs, or user-facing output. ```yaml tools: - type: think ``` ### Options The think tool has no configurable options beyond the base `permissions` field shared by all tools. ### Registered Functions - **`think(thought: str) -> str`** — Record a thought. The `thought` parameter captures the agent's reasoning; the return value is always `"Thought recorded."`. Use for breaking down complex tasks, planning multi-step approaches, reasoning about which tool to use next, or reflecting on results before responding. ### When to Use Add the think tool when you want the agent to reason more carefully before acting. It is especially useful for: - **Complex multi-tool tasks** — the agent can plan which tools to call and in what order. - **Decision-making** — the agent can weigh options before committing to an action. - **Self-correction** — the agent can reflect on intermediate results and adjust its approach. The think tool has zero overhead — it does not make any external calls, spawn subprocesses, or consume API tokens beyond the tool call itself. ### Example ```yaml # Careful reasoning agent spec: role: > You are a careful, methodical assistant. Before answering any question or taking any action, always use the think tool to reason step-by-step. model: provider: openai name: gpt-5-mini tools: - type: think - type: datetime ``` ## Script Tool Defines inline shell scripts in YAML as named, parameterized agent tools. Each script becomes a separate tool function with typed parameters. Script bodies are piped to an interpreter via stdin — no temporary files, no `shell=True`. ```yaml tools: - type: script interpreter: /bin/sh # default interpreter timeout_seconds: 30 # default timeout per script max_output_bytes: 102400 # default: 100 KB working_dir: null # default: role directory scripts: - name: disk_usage description: Check disk usage for a path interpreter: /bin/bash # override per script body: | df -h "$TARGET_PATH" parameters: - name: target_path description: Filesystem path to check required: true ``` ### Top-Level Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `scripts` | `list[ScriptDefinition]` | *(required)* | One or more script definitions. Names must be unique. | | `interpreter` | `str` | `"/bin/sh"` | Default interpreter for scripts that don't specify their own. | | `timeout_seconds` | `int` | `30` | Default timeout for scripts that don't specify their own. | | `max_output_bytes` | `int` | `102400` | Maximum output size (100 KB). Truncated output includes a `[truncated]` marker. | | `working_dir` | `str \| null` | `null` | Working directory for all scripts. `null` uses the role file's directory. | ### Script Definition | Field | Type | Default | Description | |-------|------|---------|-------------| | `name` | `str` | *(required)* | Tool function name. Must be a valid Python identifier. | | `description` | `str` | `""` | Tool description shown to the LLM. Falls back to `"Run the '' script"`. | | `body` | `str` | *(required)* | The script source. Piped to the interpreter via stdin. Must not be empty. | | `interpreter` | `str \| null` | `null` | Override the top-level interpreter for this script. `null` inherits from parent. | | `parameters` | `list[ScriptParameter]` | `[]` | Parameters injected as uppercase environment variables. | | `timeout_seconds` | `int \| null` | `null` | Override the top-level timeout for this script. `null` inherits from parent. | | `allowed_commands` | `list[str]` | `[]` | When non-empty, validates that every command line in the body uses one of these commands. Empty list skips validation. | ### Script Parameter | Field | Type | Default | Description | |-------|------|---------|-------------| | `name` | `str` | *(required)* | Parameter name. Must be a valid Python identifier. Injected as `NAME` (uppercased) in the subprocess environment. | | `description` | `str` | `""` | Parameter description for the LLM. | | `required` | `bool` | `false` | Whether the parameter is required. | | `default` | `str` | `""` | Default value for optional parameters. | ### Parameter Injection Parameters are injected as **uppercase environment variables**. A parameter named `target_path` becomes `$TARGET_PATH` in the script body: ```yaml parameters: - name: target_path description: Filesystem path to check required: true ``` ```bash # In the script body: df -h "$TARGET_PATH" ``` Default values are always applied to the environment, so scripts work correctly even when the LLM omits optional parameters. ### Security - **No `shell=True`** — Scripts are piped to the interpreter via stdin, not passed through a shell. - **Env scrubbing** — Sensitive environment variables (`OPENAI_API_KEY`, `AWS_SECRET`, etc.) are removed from the subprocess environment. - **Output bounded** — Output exceeding `max_output_bytes` is truncated with a `[truncated]` marker. - **Timeout enforcement** — Scripts that exceed their timeout are killed and a `SubprocessTimeout` error is raised. - **Working directory isolation** — When `working_dir` is set, all scripts execute in that directory. Falls back to the role file's directory. - **Docker sandbox** — When `security.docker.enabled: true`, scripts run inside Docker containers. See [Docker Sandbox](/docs/docker-sandbox). ### Examples **Single-command scripts with `allowed_commands`:** ```yaml tools: - type: script scripts: - name: disk_usage description: Check disk usage for a path allowed_commands: [df] body: | df -h "$TARGET_PATH" parameters: - name: target_path required: true ``` **Multi-command scripts (no `allowed_commands` — trusts the role author):** ```yaml tools: - type: script scripts: - name: system_info description: Show basic system information interpreter: /bin/bash body: | echo "Hostname: $(hostname)" echo "Kernel: $(uname -r)" echo "Uptime: $(uptime -p 2>/dev/null || uptime)" echo "Memory:" free -h 2>/dev/null || echo "free not available" ``` **Python interpreter:** ```yaml tools: - type: script scripts: - name: calculate description: Evaluate a math expression interpreter: python3 body: | import os, ast print(ast.literal_eval(os.environ["EXPR"])) parameters: - name: expr description: Math expression to evaluate required: true ``` ## Auto-Registered Tools ### Document Search (from `ingest`) When `spec.ingest` is configured, a `search_documents` tool is auto-registered: ``` search_documents(query: str, top_k: int = 5, source: str | None = None) -> str ``` - `query` — natural-language search string (embedded and compared against stored chunks). - `top_k` — number of results to return (default `5`). - `source` — optional glob pattern to filter results by source file path (e.g. `"*billing*"`). See [Ingestion](/docs/ingestion) for full details and the [RAG Patterns Guide](/docs/rag-guide) for usage examples. ### Memory Tools (from `memory`) When `spec.memory` is configured, up to five tools are auto-registered depending on which memory types are enabled: `remember(content, category)`, `recall(query, top_k, memory_types)`, `list_memories(category, limit, memory_type)`, `learn_procedure(content, category)`, and `record_episode(content, category)`. See [Memory](/docs/memory). ## Plugin Tools Third-party packages can register new tool types via the `initrunner.tools` entry point. Once installed (`pip install initrunner-`), the new type is available in `spec.tools` like any built-in. List discovered plugins with `initrunner plugins`. > **Note:** Plugin tools do not support the `permissions` block. The plugin parser strips non-`type` keys into a generic `config` dict, so `permissions` is silently ignored. This is a known limitation. ## Resource Limits | Tool | Limit | Behavior | |------|-------|----------| | `read_file` | 1 MB | Truncated with `[truncated]` note | | `http_request` | 100 KB | Truncated with `[truncated]` note | | `git_*` | 100 KB | Truncated with recovery hint | ### Skills # Skills Skills are reusable bundles of tools and prompt instructions that can be shared across agents. Instead of duplicating tool configs and system prompt fragments in every role, you define them once in a `SKILL.md` file and reference them from any role YAML. ## SKILL.md Format A skill is a single Markdown file with YAML frontmatter: ```markdown --- name: web-research description: Web research and summarization capability tools: - type: http base_url: https://api.example.com allowed_methods: ["GET"] - type: web_reader requires: env: - SEARCH_API_KEY bins: - curl --- ## Web Research Skill You have web research capabilities. When the user asks you to research a topic: 1. Search for relevant sources using HTTP GET requests 2. Read and extract content from web pages 3. Synthesize findings into a concise summary with citations Always cite your sources with URLs. Prefer recent, authoritative sources. ``` ### Frontmatter Fields | Field | Type | Default | Description | |-------|------|---------|-------------| | `name` | `str` | *(required)* | Unique skill identifier | | `description` | `str` | `""` | Human-readable description | | `tools` | `list` | `[]` | Tool configurations (same format as `spec.tools`) | | `requires.env` | `list[str]` | `[]` | Environment variables that must be set | | `requires.bins` | `list[str]` | `[]` | Binaries that must be on `$PATH` | ### Body The Markdown body (everything below the frontmatter) contains prompt instructions. This text is appended to the agent's `spec.role` prompt when the skill is loaded. ## Referencing Skills Add skill paths to `spec.skills` in your role YAML: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: research-assistant spec: role: | You are a research assistant. Use your skills to help the user find and summarize information. model: provider: openai name: gpt-4o-mini skills: - ./skills/web-research/SKILL.md - ./skills/summarizer/SKILL.md - data-analysis ``` ## Resolution Order When a skill path does not start with `./` or `/`, InitRunner resolves it by searching these directories in order: 1. **Current working directory** — `./SKILL.md` or `.//SKILL.md` 2. **Role file directory** — relative to the role YAML file 3. **User skills directory** — `~/.initrunner/skills//SKILL.md` Absolute and relative paths (starting with `./` or `/`) are used as-is. ## How Merging Works When an agent loads skills, two things happen: 1. **Prompt merging** — the skill's Markdown body is appended to `spec.role` as an additional section, separated by a header 2. **Tool merging** — the skill's `tools` list is added to the agent's tool set, deduplicated by type and configuration If multiple skills define the same tool type with identical config, only one instance is registered. Skills are merged in the order they appear in `spec.skills`. ### Requirement Checking Before loading, InitRunner validates requirements: - **`requires.env`** — each environment variable must be set (non-empty). Missing variables raise an error with the variable name and skill name. - **`requires.bins`** — each binary must exist on `$PATH`. Missing binaries raise an error listing the binary and skill name. ## CLI Commands ### Validate a Skill ```bash initrunner skill validate ./skills/web-research/SKILL.md ``` Checks frontmatter schema, tool configs, and requirement availability. Reports errors without loading the skill into an agent. ### List Available Skills ```bash initrunner skill list ``` Lists all skills found in the resolution paths (current directory, `~/.initrunner/skills/`). ## Scaffold a Skill ```bash initrunner init --template skill --name web-research ``` Creates a `SKILL.md` template with example frontmatter and body. ## Full Example **`skills/code-review/SKILL.md`**: ```markdown --- name: code-review description: Code review and static analysis capability tools: - type: filesystem root_path: . read_only: true - type: git repo_path: . read_only: true - type: shell allowed_commands: [ruff, mypy] require_confirmation: false timeout_seconds: 30 requires: bins: - ruff - mypy --- ## Code Review Skill You can review code changes and provide feedback. Follow this workflow: 1. Use `git_diff` or `git_changed_files` to identify what changed 2. Read the modified files to understand the context 3. Run `ruff check .` for linting issues 4. Run `mypy .` for type errors 5. Provide a structured review with: - Summary of changes - Issues found (bugs, style, types) - Suggestions for improvement Be specific — reference file names and line numbers in your feedback. ``` **`reviewer.yaml`** — a role that uses this skill: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: code-reviewer description: Reviews code changes using static analysis tools spec: role: | You are a senior code reviewer. When given a branch or commit range, review the changes and produce a structured report. model: provider: openai name: gpt-4o-mini temperature: 0.0 skills: - ./skills/code-review/SKILL.md guardrails: max_tokens_per_run: 30000 max_tool_calls: 25 timeout_seconds: 120 ``` ```bash initrunner run reviewer.yaml -p "Review the changes in the last 3 commits" ``` ### Memory # Memory InitRunner's memory system gives agents three capabilities: **short-term session persistence** for resuming conversations, **long-term typed memory** (semantic, episodic, and procedural), and **automatic consolidation** that extracts durable facts from episodic records. - **Semantic memory** — facts and knowledge (e.g. "the user prefers dark mode") - **Episodic memory** — what happened during tasks (e.g. "deployed v2.1 to staging, rollback needed") - **Procedural memory** — learned policies and patterns (e.g. "always run tests before deploying") All memory types are backed by a single database per agent using a configurable store backend (default: `zvec` for vector similarity search). The store is dimension-agnostic — embedding dimensions are auto-detected on first use. ## Quick Start ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: assistant description: Agent with rich memory spec: role: | You are a helpful assistant with long-term memory. Use the remember() tool to save important facts. Use the recall() tool to search your memories before answering. Use the learn_procedure() tool to record useful patterns. model: provider: openai name: gpt-4o-mini memory: max_sessions: 10 max_resume_messages: 20 semantic: max_memories: 1000 episodic: max_episodes: 500 procedural: max_procedures: 100 consolidation: enabled: true interval: after_session ``` Minimal backward-compatible config still works — a bare `memory:` section with just `max_memories` enables semantic memory with defaults for all other types: ```yaml memory: max_memories: 1000 ``` ```bash # Interactive session (auto-saves history) initrunner run role.yaml -i # Resume where you left off initrunner run role.yaml -i --resume # Manage memory initrunner memory list role.yaml initrunner memory list role.yaml --type episodic initrunner memory clear role.yaml initrunner memory consolidate role.yaml initrunner memory export role.yaml -o memories.json ``` ## Memory in Chat Mode In `initrunner chat`, memory is on by default. No YAML file needed. ```bash # Memory on (default) initrunner chat # Resume previous session initrunner chat --resume # Disable memory initrunner chat --no-memory ``` Chat mode creates a lightweight memory store with semantic memory enabled. Use `--resume` to load the most recent session and pick up where you left off. Use `--no-memory` to start fresh every time. ## Memory Types ### Semantic Facts and knowledge extracted from conversations or explicitly saved by the agent. This is the default memory type and the one used by the `remember()` tool. Semantic memories are retrieved via `recall()` and are also the output of the consolidation process (extracting durable facts from episodic records). ### Episodic Records of what happened during agent tasks — outcomes, decisions, errors, and events. Episodic memories are created in three ways: 1. The agent calls `record_episode()` explicitly. 2. Autonomous runs auto-capture an episode when `finish_task` is called (see [Episodic Auto-Capture](#episodic-auto-capture)). 3. Daemon trigger executions auto-capture an episode after each run. Episodic memories serve as raw material for consolidation: the consolidation process reads unconsolidated episodes, extracts semantic facts via an LLM, and marks them as consolidated. ### Procedural Learned policies, patterns, and best practices. Procedural memories are created via the `learn_procedure()` tool and are automatically injected into the system prompt on every agent run (see [Procedural Memory Injection](#procedural-memory-injection)). Use procedural memory for instructions the agent should always follow, like "always confirm before deleting files" or "use snake_case for Python variables". ## Configuration Memory is configured in the `spec.memory` section: ```yaml spec: memory: max_sessions: 10 # default: 10 max_memories: 1000 # deprecated — use semantic.max_memories max_resume_messages: 20 # default: 20 store_backend: zvec # default: "zvec" store_path: null # default: ~/.initrunner/memory/.db embeddings: provider: "" # default: "" (derives from spec.model.provider) model: "" # default: "" (uses provider default) base_url: "" # default: "" (custom endpoint URL) api_key_env: "" # default: "" (env var holding API key) episodic: enabled: true # default: true max_episodes: 500 # default: 500 semantic: enabled: true # default: true max_memories: 1000 # default: 1000 procedural: enabled: true # default: true max_procedures: 100 # default: 100 consolidation: enabled: true # default: true interval: after_session # default: "after_session" max_episodes_per_run: 20 # default: 20 model_override: null # default: null (uses agent's model) ``` ### Top-Level Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `max_sessions` | `int` | `10` | Maximum number of sessions to keep. Oldest sessions are pruned on REPL exit. | | `max_memories` | `int` | `1000` | **Deprecated.** Use `semantic.max_memories`. If set to a non-default value and `semantic.max_memories` is at default, the value is synced for backward compatibility. | | `max_resume_messages` | `int` | `20` | Maximum number of messages loaded when using `--resume`. | | `store_backend` | `str` | `"zvec"` | Memory store backend. Currently only `zvec` is supported. | | `store_path` | `str \| null` | `null` | Custom path for the memory database. Default: `~/.initrunner/memory/.db`. | ### Embedding Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `embeddings.provider` | `str` | `""` | Embedding provider. Empty string derives from `spec.model.provider`. | | `embeddings.model` | `str` | `""` | Embedding model name. Empty string uses the provider default. | | `embeddings.base_url` | `str` | `""` | Custom endpoint URL. Triggers OpenAI-compatible mode. | | `embeddings.api_key_env` | `str` | `""` | Env var name holding the API key for custom endpoints. Empty uses provider default. | ### Episodic Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `episodic.enabled` | `bool` | `true` | Enable episodic memory type and the `record_episode()` tool. | | `episodic.max_episodes` | `int` | `500` | Maximum episodic memories to keep. Oldest are pruned when new ones are added. | ### Semantic Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `semantic.enabled` | `bool` | `true` | Enable semantic memory type and the `remember()` tool. | | `semantic.max_memories` | `int` | `1000` | Maximum semantic memories to keep. Oldest are pruned when new ones are added. | ### Procedural Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `procedural.enabled` | `bool` | `true` | Enable procedural memory type and the `learn_procedure()` tool. | | `procedural.max_procedures` | `int` | `100` | Maximum procedural memories to keep. Oldest are pruned when new ones are added. | ### Consolidation Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `consolidation.enabled` | `bool` | `true` | Enable automatic consolidation of episodic memories into semantic facts. | | `consolidation.interval` | `str` | `"after_session"` | When to run consolidation: `after_session` (on REPL exit), `after_autonomous` (on autonomous loop exit), or `manual` (CLI only). | | `consolidation.max_episodes_per_run` | `int` | `20` | Maximum unconsolidated episodes to process per consolidation run. | | `consolidation.model_override` | `str \| null` | `null` | Model to use for consolidation LLM calls. Defaults to the agent's model. | ## Short-Term: Session Persistence Session persistence saves REPL conversation history to SQLite after each turn, enabling the `--resume` flag. ### How It Works 1. During an interactive REPL session, the full PydanticAI message history is saved after every turn. 2. Each session gets a unique ID (random 12-character hex). 3. When `--resume` is used, the most recent session for the agent is loaded. 4. Only the last `max_resume_messages` messages are loaded to stay within context window limits. 5. If the loaded history starts with a `ModelResponse` (which is invalid), leading `ModelResponse` messages are skipped until a `ModelRequest` is found. ### Active Session History Limit During an active REPL or TUI session, message history is trimmed to `max_resume_messages * 2` (default: 40 messages) after each turn. This prevents unbounded growth during long conversations. The trimming: - Keeps the most recent messages (sliding window). - Ensures the history starts with a `ModelRequest` (never a `ModelResponse`). - Applies in both the CLI REPL (`initrunner run -i`) and the TUI chat screen. ### System Prompt Filtering When saving sessions, all `SystemPromptPart` entries are stripped from `ModelRequest` messages. This ensures that: - Stale system prompts from a previous `role.yaml` version don't persist. - The current `spec.role` is always used when resuming. - Session data is more compact. ### Session Pruning Old sessions beyond `max_sessions` are deleted (oldest first). Pruning runs automatically: - **REPL mode**: on session exit. - **Daemon mode**: after each trigger execution (when memory is configured). This keeps the memory database from growing indefinitely. ### Never-Raises Guarantee Session saving follows a never-raises pattern: if writing to the database fails, the error is printed to stderr but the agent continues running. This prevents database issues from crashing interactive sessions. ## Long-Term: Memory Tools When `spec.memory` is configured, up to five tools are auto-registered depending on which memory types are enabled. ### `remember(content: str, category: str = "general") -> str` Stores a piece of information as a **semantic** memory with an embedding for later retrieval. Only registered when `semantic.enabled` is `true`. - The `category` is sanitized: lowercased, non-alphanumeric characters replaced with underscores. - An embedding is generated from the content using the configured embedding model. - After storing, memories are pruned to `semantic.max_memories` (oldest removed). - Returns a confirmation string with the memory ID and category. ### `recall(query: str, top_k: int = 5, memory_types: list[str] | None = None) -> str` Searches all memory types by semantic similarity. Always registered when `spec.memory` is configured. - Generates an embedding from the query. - Finds the `top_k` most similar memories using vector search. - Pass `memory_types` to filter by type (e.g. `["semantic", "procedural"]`). - Returns results formatted as: ``` [Type: semantic | Category: preferences | Score: 0.912 | 2025-06-01T10:30:00+00:00] The user prefers dark mode and vim keybindings. --- [Type: episodic | Category: autonomous_run | Score: 0.845 | 2025-06-01T09:15:00+00:00] Deployed v2.1 to staging. Tests passed but rollback was needed due to memory leak. ``` The score is `1 - distance` (higher is more similar). ### `list_memories(category: str | None = None, limit: int = 20, memory_type: str | None = None) -> str` Lists recent memories, optionally filtered by category or type. Always registered when `spec.memory` is configured. Returns entries formatted as: ``` [semantic:preferences] (2025-06-01T10:30:00+00:00) The user prefers dark mode. [episodic:autonomous_run] (2025-06-01T09:15:00+00:00) Deployed v2.1 to staging. ``` ### `learn_procedure(content: str, category: str = "general") -> str` Stores a learned procedure, policy, or pattern as a **procedural** memory. Only registered when `procedural.enabled` is `true`. - The `category` is sanitized the same way as `remember()`. - After storing, memories are pruned to `procedural.max_procedures` (oldest removed). - Procedural memories are auto-injected into the system prompt on future runs (see [Procedural Memory Injection](#procedural-memory-injection)). ### `record_episode(content: str, category: str = "general") -> str` Records an episode — what happened during a task or interaction. Only registered when `episodic.enabled` is `true`. - The `category` is sanitized the same way as `remember()`. - After storing, memories are pruned to `episodic.max_episodes` (oldest removed). - Use this to capture outcomes, decisions made, errors encountered, or other events. ## Episodic Auto-Capture In autonomous and daemon modes, episodic memories are captured automatically — the agent does not need to call `record_episode()` explicitly. ### Autonomous Mode When `finish_task` is called with a summary, the summary is persisted as an episodic memory with category `autonomous_run`. This happens after each autonomous loop iteration that produces a result. ### Daemon Mode After each trigger execution, the run result summary is captured as an episodic memory. The metadata includes the trigger type (e.g. `cron`, `file_watch`, `webhook`). ### Interactive Mode Interactive REPL sessions do **not** auto-capture episodic memories. Use the `record_episode()` tool explicitly if needed. ### Never-Raises Guarantee Episodic auto-capture follows a never-raises pattern: if embedding or storage fails, a warning is logged but the agent run is not affected. ## Consolidation Consolidation is the process of extracting durable semantic facts from episodic memories using an LLM. It reads unconsolidated episodes, sends them to the model with a structured prompt, parses `CATEGORY: content` lines from the output, and stores each extracted fact as a new semantic memory. ### When It Runs | `consolidation.interval` | Trigger | |---------------------------|---------| | `after_session` | On interactive REPL exit | | `after_autonomous` | On autonomous loop exit | | `manual` | Only via `initrunner memory consolidate` CLI | Consolidation can always be triggered manually via the CLI regardless of the `interval` setting. ### How It Works 1. Fetch up to `max_episodes_per_run` unconsolidated episodic memories (oldest first). 2. Format them into a prompt and send to the consolidation model. 3. Parse `CATEGORY: content` lines from the LLM output. 4. Store each extracted fact as a semantic memory with `metadata: {"source": "consolidation"}`. 5. Mark the processed episodes as consolidated (sets `consolidated_at` timestamp). ### Failure Semantics Consolidation follows a never-raises pattern. If the LLM call or storage fails, a warning is logged and `0` is returned. Episodes are only marked as consolidated after all semantic memories are successfully stored. ## Procedural Memory Injection When `procedural.enabled` is `true`, procedural memories are automatically loaded into the system prompt on every agent run. Up to 20 of the most recent procedural memories are injected as a `## Learned Procedures and Policies` section: ``` ## Learned Procedures and Policies - [deployment] Always run tests before deploying to production - [code_review] Check for SQL injection in any database queries - [communication] Summarize changes in bullet points for the user ``` This injection happens transparently — the agent sees these as part of its system prompt and follows them as standing instructions. ## Database Schema The memory database contains four tables: ### `store_meta` Key-value metadata (e.g. dimensions, embedding model): | Column | Type | Description | |--------|------|-------------| | `key` | `TEXT PRIMARY KEY` | Metadata key (e.g. `"dimensions"`, `"embedding_model"`) | | `value` | `TEXT` | Metadata value (e.g. `"1536"`, `"openai:text-embedding-3-small"`) | ### `sessions` | Column | Type | Description | |--------|------|-------------| | `id` | `INTEGER PRIMARY KEY` | Auto-incrementing row ID | | `session_id` | `TEXT` | Unique session identifier | | `agent_name` | `TEXT` | Agent name from `metadata.name` | | `timestamp` | `TEXT` | ISO 8601 timestamp | | `messages_json` | `TEXT` | JSON-serialized PydanticAI message history | Indexed on `(agent_name, timestamp DESC)` for fast latest-session lookups. ### `memories` | Column | Type | Description | |--------|------|-------------| | `id` | `INTEGER PRIMARY KEY` | Auto-incrementing memory ID | | `content` | `TEXT` | Memory content | | `category` | `TEXT` | Category label (default: `"general"`) | | `created_at` | `TEXT` | ISO 8601 creation timestamp | | `memory_type` | `TEXT` | One of `episodic`, `semantic`, `procedural`. Default: `semantic`. Has a `CHECK` constraint. | | `metadata_json` | `TEXT` | Optional JSON metadata (e.g. `{"trigger_type": "cron"}`, `{"source": "consolidation"}`) | | `consolidated_at` | `TEXT` | ISO 8601 timestamp when the episode was consolidated. `NULL` for unconsolidated or non-episodic memories. | Indexes: - `idx_memories_category` on `(category)` - `idx_memories_type` on `(memory_type)` - `idx_memories_type_category` on `(memory_type, category)` Existing databases are auto-migrated: the `memory_type`, `metadata_json`, and `consolidated_at` columns are added via `ALTER TABLE` if missing, and new indexes are created. ### `memories_vec` Virtual table for vector similarity search (created lazily on first `remember()`, `learn_procedure()`, or `record_episode()` call): | Column | Type | Description | |--------|------|-------------| | `rowid` | `INTEGER` | Matches `memories.id` | | `embedding` | `float[N]` | Vector embedding (dimension auto-detected from model) | ## CLI Commands ### `memory clear` Clear memory data for an agent. ```bash initrunner memory clear role.yaml # clear all (prompts for confirmation) initrunner memory clear role.yaml --force # skip confirmation initrunner memory clear role.yaml --sessions-only # clear only sessions initrunner memory clear role.yaml --memories-only # clear only long-term memories initrunner memory clear role.yaml --type semantic # clear only semantic memories initrunner memory clear role.yaml --type episodic # clear only episodic memories ``` | Option | Type | Default | Description | |--------|------|---------|-------------| | `role_file` | `Path` | *(required)* | Path to the role YAML file. | | `--sessions-only` | `bool` | `false` | Only clear session history. | | `--memories-only` | `bool` | `false` | Only clear long-term memories. | | `--type` | `str` | `null` | Clear only a specific memory type: `episodic`, `semantic`, or `procedural`. | | `--force` | `bool` | `false` | Skip the confirmation prompt. | If the memory store database doesn't exist, the command prints "No memory store found." and exits. ### `memory export` Export all long-term memories to a JSON file. ```bash initrunner memory export role.yaml # exports to memories.json initrunner memory export role.yaml -o my-export.json # custom output path ``` | Option | Type | Default | Description | |--------|------|---------|-------------| | `role_file` | `Path` | *(required)* | Path to the role YAML file. | | `-o, --output` | `Path` | `memories.json` | Output JSON file path. | The exported JSON is an array of objects: ```json [ { "id": 1, "content": "The user prefers dark mode.", "category": "preferences", "created_at": "2025-06-01T10:30:00+00:00", "memory_type": "semantic", "metadata": null }, { "id": 2, "content": "Deployed v2.1 to staging successfully.", "category": "autonomous_run", "created_at": "2025-06-02T14:00:00+00:00", "memory_type": "episodic", "metadata": {"trigger_type": "cron"} } ] ``` ### `memory list` List stored memories for an agent. ```bash initrunner memory list role.yaml # list all (default limit: 20) initrunner memory list role.yaml --type procedural # filter by type initrunner memory list role.yaml --category deployment # filter by category initrunner memory list role.yaml --limit 50 # custom limit ``` | Option | Type | Default | Description | |--------|------|---------|-------------| | `role_file` | `Path` | *(required)* | Path to the role YAML file. | | `--type` | `str` | `null` | Filter by memory type: `episodic`, `semantic`, or `procedural`. | | `--category` | `str` | `null` | Filter by category. | | `--limit` | `int` | `20` | Maximum number of results. | ### `memory consolidate` Manually run memory consolidation — extract semantic facts from unconsolidated episodic memories. ```bash initrunner memory consolidate role.yaml ``` | Option | Type | Default | Description | |--------|------|---------|-------------| | `role_file` | `Path` | *(required)* | Path to the role YAML file. | This command always runs consolidation regardless of the `consolidation.interval` setting. It processes up to `consolidation.max_episodes_per_run` unconsolidated episodes. ## Store Location ``` ~/.initrunner/memory/.db ``` Override with `store_path` in the memory config. The directory is created automatically if it doesn't exist. ## Shared Memory Multiple agents can share a single memory database, allowing one agent's `remember()` calls to be visible to another agent's `recall()`. There are two mechanisms: - **Compose**: set `spec.shared_memory.enabled: true` in a compose definition to give all services a common store. See [Agent Composer: Shared Memory](/docs/compose#shared-memory). - **Delegation**: set `shared_memory.store_path` on a delegate tool to share memory between inline sub-agents. See [Delegation: Shared Memory](/docs/delegation#shared-memory). Both work by overriding `store_path` (and optionally `max_memories`) on each agent's memory config at startup, pointing them at the same SQLite database. Concurrent access from multiple service threads is safe — SQLite WAL mode and `busy_timeout` handle contention without additional locking. ## Dimension & Model Identity Tracking The memory store tracks embedding dimensions and model identity: - **Session-only usage**: the store works without knowing dimensions — the `memories_vec` table is created lazily on the first `remember()` call. - **First `remember()` call**: dimensions and the embedding model identity are detected and written to `store_meta`. - **Subsequent opens**: dimensions and model identity are read from `store_meta`. An `EmbeddingModelChangedError` is raised if the model has changed; a `DimensionMismatchError` is raised if dimensions conflict. - **Migration**: pre-existing stores default to 1536. ## Scaffold ```bash initrunner init --name assistant --template memory ``` This generates a `role.yaml` with `memory` pre-configured and a system prompt that instructs the agent to use `remember()`, `recall()`, and `list_memories()`. ## Embedding Models Memory uses the same embedding provider resolution as [Ingestion](/docs/ingestion#embedding-models): 1. `memory.embeddings.model` — If set, used directly. 2. `memory.embeddings.provider` — Used to look up the default model. 3. `spec.model.provider` — Falls back to the agent's model provider. ### Provider Defaults | Provider | Default Embedding Model | |----------|------------------------| | `openai` | `openai:text-embedding-3-small` | | `anthropic` | `openai:text-embedding-3-small` | | `google` | `google:text-embedding-004` | | `ollama` | `ollama:nomic-embed-text` | ### Ingestion # Ingestion InitRunner's ingestion pipeline extracts text from source files, splits it into chunks, generates embeddings, and stores vectors in a local SQLite database. Once ingested, an agent can search documents at runtime via the auto-registered `search_documents` tool. ## Quick Start ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: kb-agent description: Knowledge base agent spec: role: | You are a knowledge assistant. Use search_documents to find relevant content before answering. Always cite your sources. model: provider: openai name: gpt-4o-mini ingest: sources: - "./docs/**/*.md" - "./knowledge-base/**/*.txt" chunking: strategy: fixed chunk_size: 512 chunk_overlap: 50 ``` ```bash # Ingest documents initrunner ingest role.yaml # Run the agent (search_documents is auto-registered) initrunner run role.yaml -p "What does the onboarding guide say?" ``` ## Walkthrough: Build a Knowledge Base Agent This walkthrough builds a complete RAG agent from scratch — set up docs, configure the agent, ingest, and query. ### 1. Set up your docs directory ```bash mkdir -p docs # Add your markdown files to ./docs/ ``` ### 2. Create the agent ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: rag-agent description: Knowledge base Q&A agent with document ingestion spec: role: | You are a helpful documentation assistant. You answer user questions using the ingested knowledge base. Rules: - ALWAYS call search_documents before answering a question - Base your answers only on information found in the documents - Cite the source document for each claim (e.g., "Per the Getting Started guide, ...") - If search_documents returns no relevant results, say so honestly rather than guessing - When a user asks about a topic covered across multiple documents, synthesize the information and cite all relevant sources - Use read_file to view a full document when the search snippet is not enough context model: provider: openai name: gpt-4o-mini temperature: 0.1 ingest: sources: - ./docs/**/*.md chunking: strategy: paragraph chunk_size: 512 chunk_overlap: 50 embeddings: provider: openai model: text-embedding-3-small tools: - type: filesystem root_path: ./docs read_only: true allowed_extensions: - .md guardrails: max_tokens_per_run: 30000 max_tool_calls: 15 timeout_seconds: 120 ``` > **Why `paragraph` chunking?** It splits on double newlines first, then merges small paragraphs until `chunk_size` is reached. This preserves natural document structure — a paragraph about "installation" stays together instead of being split mid-sentence. Use `fixed` for code files and logs where structure doesn't matter. ### 3. Ingest the documents ```bash initrunner ingest rag-agent.yaml ``` ``` Resolving sources... ./docs/**/*.md → 4 files Extracting text... docs/getting-started.md (2,847 chars) docs/faq.md (3,214 chars) docs/api-reference.md (5,102 chars) docs/changelog.md (1,456 chars) Chunking (paragraph, size=512, overlap=50)... → 28 chunks Embedding with openai:text-embedding-3-small... → 28 embeddings Stored in ~/.initrunner/stores/rag-agent.db ``` ### 4. Query the agent ```bash initrunner run rag-agent.yaml -p "How do I create a database?" ``` The agent calls `search_documents("create database")`, gets matching chunks with source file names and similarity scores, then answers with citations. ### 5. Re-index when docs change ```bash # Safe to re-run — deletes old chunks and re-inserts initrunner ingest rag-agent.yaml ``` See the [Examples](/docs/examples) page for the complete RAG agent with sample docs. ## Pipeline ```mermaid flowchart LR G[Glob Sources] --> E[Extract Text] E --> C[Chunk] C --> EM[Embed] EM --> S[Store in SQLite] S --> SE[Search] SE --> A[Agent] ``` 1. **Resolve sources** — Glob patterns are expanded into file paths relative to the role file's directory. 2. **Extract text** — Each file is passed through a format-specific extractor. 3. **Chunk text** — Extracted text is split into overlapping chunks. 4. **Embed** — Chunks are converted to vector embeddings. 5. **Store** — Embeddings and text are stored in SQLite backed by zvec. ## Configuration | Field | Type | Default | Description | |-------|------|---------|-------------| | `sources` | `list[str]` | *(required)* | Glob patterns for source files | | `watch` | `bool` | `false` | Reserved for future use | | `chunking.strategy` | `str` | `"fixed"` | `"fixed"` or `"paragraph"` | | `chunking.chunk_size` | `int` | `512` | Maximum chunk size in characters | | `chunking.chunk_overlap` | `int` | `50` | Overlapping characters between chunks | | `embeddings.provider` | `str` | `""` | Embedding provider (empty = derives from model) | | `embeddings.model` | `str` | `""` | Embedding model (empty = provider default) | | `embeddings.api_key_env` | `str` | `""` | Env var name holding the embedding API key. When empty, the default for the resolved provider is used (`OPENAI_API_KEY` for OpenAI/Anthropic, `GOOGLE_API_KEY` for Google). | | `store_backend` | `str` | `"zvec"` | Vector store backend | | `store_path` | `str \| null` | `null` | Custom path (default: `~/.initrunner/stores/.db`) | ## Chunking Strategies ### Fixed (`strategy: fixed`) Splits text into fixed-size character windows with overlap. Best for uniform document types, code files, and logs. ### Paragraph (`strategy: paragraph`) Splits on double newlines first, then merges small paragraphs until `chunk_size` is reached. Preserves natural document structure. Best for prose, markdown, and documentation. ### Choosing a Strategy and Parameters - **Use `paragraph`** for prose, markdown, and documentation — it preserves natural boundaries so a paragraph about "installation" stays together. - **Use `fixed`** for code files, logs, and machine-generated text where structure doesn't carry semantic meaning. **`chunk_size` rules of thumb:** | Use Case | Recommended `chunk_size` | |----------|-------------------------| | Short-answer Q&A | 256–512 | | Dense technical content, long-form docs | 512–1024 | **`chunk_overlap`** should be roughly 10% of `chunk_size` (e.g. `50` for a `512` chunk). Overlap ensures that information spanning a boundary is present in at least one chunk. ### Recommendations by Document Type | Document type | Strategy | `chunk_size` | `chunk_overlap` | Notes | |---|---|---|---|---| | Markdown / articles | `paragraph` | 512 | 50 | Preserves natural paragraph boundaries | | Code files | `fixed` | 1024 | 100 | Larger windows keep function context together | | API references | `paragraph` | 256 | 50 | Short, dense entries benefit from smaller chunks | | CSV / tabular data | `fixed` | 1024 | 0 | No overlap — rows must not be split across chunks | | PDFs | `fixed` | 512–1024 | 50–100 | PDF layout varies; fixed chunking is more predictable | ## Supported File Formats ### Core Formats (always available) | Extension | Extractor | |-----------|-----------| | `.txt` | Plain text (UTF-8) | | `.md` | Plain text (UTF-8) | | `.rst` | Plain text (UTF-8) | | `.csv` | CSV rows joined with commas and newlines | | `.json` | Pretty-printed JSON | | `.html`, `.htm` | HTML to Markdown (scripts/styles removed) | ### Optional Formats (`pip install initrunner[ingest]`) | Extension | Extractor | Library | |-----------|-----------|---------| | `.pdf` | PDF to Markdown | `pymupdf4llm` | | `.docx` | Paragraphs joined with double newlines | `python-docx` | | `.xlsx` | Sheets as CSV with title headers | `openpyxl` | ## The `search_documents` Tool When `spec.ingest` is configured, a search tool is auto-registered: ``` search_documents(query: str, top_k: int = 5, source: str | None = None) -> str ``` | Parameter | Type | Default | Description | |-----------|------|---------|-------------| | `query` | `str` | *(required)* | Natural-language search string (embedded and compared against stored chunks) | | `top_k` | `int` | `5` | Number of results to return | | `source` | `str \| None` | `None` | Glob pattern to filter results by source file path | The tool creates an embedding from the query, searches the vector store for the most similar chunks, and returns results with source attribution and similarity scores. **Result format:** ``` [1] (score: 0.87) ./docs/getting-started.md To create a new project, run `initrunner init`... [2] (score: 0.82) ./docs/faq.md InitRunner supports multiple model providers... ``` **Source filtering example:** ```python # Search only billing docs search_documents("refund policy", source="*billing*") # Search a specific file search_documents("authentication", source="*/api-reference.md") ``` If no documents have been ingested, the tool returns a message directing you to run `initrunner ingest`. ## Re-indexing Running `initrunner ingest` again is safe and idempotent: 1. Resolves glob patterns to find current files. 2. Deletes all existing chunks from each source file. 3. Inserts new chunks from fresh extraction. Files that no longer match the patterns keep their old chunks. ## Embedding Models Provider resolution priority: 1. `ingest.embeddings.model` — if set, used directly 2. `ingest.embeddings.provider` — used to look up the default 3. `spec.model.provider` — falls back to agent's model provider | Provider | Default Embedding Model | |----------|------------------------| | `openai` | `openai:text-embedding-3-small` | | `anthropic` | `openai:text-embedding-3-small` | | `google` | `google:text-embedding-004` | | `ollama` | `ollama:nomic-embed-text` | > Anthropic has no embeddings API. Agents using `provider: anthropic` fall back to `openai:text-embedding-3-small` by default (requires `OPENAI_API_KEY`). To avoid the OpenAI dependency, set `embeddings.provider: google` or `embeddings.provider: ollama`. ## Scaffold ```bash initrunner init --name kb-agent --template rag ``` ## Troubleshooting ### No results from `search_documents` - **Documents not ingested** — Run `initrunner ingest role.yaml` before querying. The tool returns a message if the store is empty. - **Query too specific** — Try broader or rephrased queries. Embedding search is semantic, not keyword-exact. - **Wrong embedding model** — If you changed the embedding model after ingesting, re-ingest so all vectors use the same model. ### `EmbeddingModelChangedError` Raised when the configured embedding model differs from the one used to create the existing store. Vectors from different models are incompatible. Fix by re-ingesting: ```bash initrunner ingest role.yaml --force ``` ### `DimensionMismatchError` The vector dimensions in the store don't match the current model's output dimensions. This usually happens when switching between embedding providers. Re-ingest with `--force` to rebuild the store. ### Optional format extraction errors If `.pdf`, `.docx`, or `.xlsx` files fail to extract, install the optional dependencies: ```bash pip install "initrunner[ingest]" ``` This installs `pymupdf4llm`, `python-docx`, and `openpyxl`. ### API key not set Embedding keys are validated at startup. If the required key is missing you will see a clear error message identifying which variable to set. | Provider | Required env var | Notes | |----------|-----------------|-------| | `openai` | `OPENAI_API_KEY` | | | `anthropic` | `OPENAI_API_KEY` | Anthropic has no native embeddings — falls back to OpenAI by default; set `embeddings.provider` to switch | | `google` | `GOOGLE_API_KEY` | | | `ollama` | *(none)* | Runs locally | **Override the variable name** — if your key is stored under a non-default name, set `embeddings.api_key_env` in your `ingest` or `memory` config: ```yaml spec: ingest: embeddings: provider: openai api_key_env: MY_EMBED_KEY # read from MY_EMBED_KEY instead of OPENAI_API_KEY ``` **Diagnose key issues** with: ```bash initrunner doctor ``` The Embedding Providers table shows which keys are set and which are missing. ### `zvec` not available InitRunner requires the `zvec` extension. Install it with: ```bash pip install zvec ``` On some systems you may also need to set `ZVEC_PATH` if the extension is in a non-standard location. ### RAG Patterns & Guide # RAG Patterns & Guide This guide covers practical patterns for using InitRunner's retrieval-augmented generation (RAG) capabilities. For full configuration reference, see [Ingestion](/docs/ingestion) and [Memory](/docs/memory). ## RAG vs Memory — When to Use Which InitRunner has two systems for giving agents access to information beyond their training data: | Aspect | Ingestion (RAG) | Memory | |---|---|---| | **Purpose** | Search external documents | Remember learned information | | **Data source** | Files on disk, URLs | Agent's own observations | | **Who writes** | You (via `initrunner ingest`) | Agent (via `remember()` tool) | | **Who reads** | Agent (via `search_documents()`) | Agent (via `recall()`) | | **Best for** | Knowledge base Q&A, doc search | Personalization, context carry-over | | **Persistence** | Rebuilt on each `ingest` run | Accumulates across sessions | You can use both together — ingestion for your docs, memory for user preferences: ```yaml spec: ingest: sources: - "./docs/**/*.md" memory: semantic: max_memories: 500 ``` ## End-to-End Walkthrough ### 1. Create a role with ingestion Create `role.yaml`: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: docs-agent description: Documentation Q&A agent spec: role: | You are a documentation assistant. ALWAYS call search_documents before answering questions. Cite your sources. model: provider: openai name: gpt-4o-mini ingest: sources: - "./docs/**/*.md" chunking: strategy: paragraph chunk_size: 512 chunk_overlap: 50 ``` ### 2. Add some documents Create a `docs/` directory with markdown files: ``` docs/ ├── getting-started.md ├── api-reference.md └── faq.md ``` ### 3. Ingest documents ```bash $ initrunner ingest role.yaml Ingesting documents for docs-agent... ✓ Stored 47 chunks from 3 files ``` ### 4. Run the agent ```bash $ initrunner run role.yaml -p "How do I authenticate?" ``` The agent calls `search_documents("authenticate")` behind the scenes, retrieves matching chunks from your docs, and uses them to answer. ### 5. Interactive session ```bash $ initrunner run role.yaml -i docs-agent> How do I get an API key? I found the answer in your documentation. Per the Getting Started guide (./docs/getting-started.md), you can generate an API key by navigating to Settings > API Keys in your dashboard... docs-agent> What rate limits apply? According to the API Reference (./docs/api-reference.md), the default rate limit is 100 requests per minute per API key... ``` ## Choosing an Embedding Model The embedding model determines how well semantic search performs. Different models trade off between dimension size, cost, speed, and quality. | Model | Provider | Dimensions | Notes | |-------|----------|-----------|-------| | `text-embedding-3-small` | OpenAI | 1536 | Fast and cheap — good default for most use cases | | `text-embedding-3-large` | OpenAI | 3072 | Higher quality at higher cost | | `text-embedding-004` | Google | 768 | Cost-effective; strong multilingual support | | `nomic-embed-text` | Ollama | 768 | Fully local — no API key or network needed | ### Which model should I use? - **Cost-sensitive:** Google `text-embedding-004` or Ollama `nomic-embed-text` - **Precision-critical:** OpenAI `text-embedding-3-large` - **Fully local / no API keys:** Ollama `nomic-embed-text` - **Google ecosystem:** Google `text-embedding-004` The default (`openai:text-embedding-3-small`) is a sensible starting point for most projects. See [Providers](/docs/providers) for the full embedding configuration reference and how to override the default. ## Common Patterns ### Basic knowledge base Single format, paragraph chunking for natural document boundaries: ```yaml ingest: sources: - "./knowledge-base/**/*.md" chunking: strategy: paragraph chunk_size: 512 chunk_overlap: 50 ``` ### Multi-format knowledge base Mix HTML, Markdown, and PDF sources. Install `initrunner[ingest]` for PDF support: ```yaml ingest: sources: - "./docs/**/*.md" - "./docs/**/*.html" - "./docs/**/*.pdf" chunking: strategy: fixed chunk_size: 1024 chunk_overlap: 100 ``` ### URL-based ingestion Ingest content from remote URLs alongside local files: ```yaml ingest: sources: - "./local-docs/**/*.md" - "https://docs.example.com/api/reference" - "https://docs.example.com/changelog" ``` URL content is hashed — re-running `ingest` skips unchanged pages. ### Auto re-indexing with file watch trigger Use a `file_watch` trigger to re-ingest when source files change: ```yaml spec: ingest: sources: - "./knowledge-base/**/*.md" triggers: - type: file_watch paths: - ./knowledge-base extensions: - .md prompt_template: "Knowledge base updated: {path}. Re-index." debounce_seconds: 1.0 ``` ### Using `source` filter to scope searches When your knowledge base spans multiple topics, use the `source` parameter to narrow results: ```yaml spec: role: | You are a support agent. When the user asks about billing, search only billing docs: search_documents(query, source="*billing*"). For technical issues, search: search_documents(query, source="*troubleshooting*"). ingest: sources: - "./kb/billing/**/*.md" - "./kb/troubleshooting/**/*.md" - "./kb/general/**/*.md" ``` ### Fully local RAG with Ollama No external API keys needed — use Ollama for both the LLM and embeddings: ```yaml spec: model: provider: ollama name: llama3.2 ingest: sources: - "./docs/**/*.md" embeddings: provider: ollama model: nomic-embed-text ``` See the [Providers](/docs/providers) page for Ollama setup instructions. ## Next Steps - [Ingestion reference](/docs/ingestion) — full configuration options, chunking strategies, embedding models - [Memory reference](/docs/memory) — session persistence and long-term memory (semantic, episodic, procedural) - [Tools reference](/docs/tools) — built-in and custom tool types ### Multimodal Input # Multimodal Input InitRunner supports sending images, audio, video, and documents alongside text prompts. Multimodal input works across the CLI, interactive REPL, OpenAI-compatible API server, web dashboard, and TUI. ## Supported File Types | Category | Extensions | Notes | |----------|-----------|-------| | Image | `.jpg`, `.jpeg`, `.png`, `.gif`, `.webp` | Most models support these natively | | Audio | `.mp3`, `.wav`, `.ogg`, `.flac`, `.aac` | Requires model support (e.g. `gpt-4o-audio-preview`) | | Video | `.mp4`, `.webm`, `.mov`, `.mkv` | Limited model support | | Document | `.pdf`, `.docx`, `.xlsx` | Sent as binary content | | Text | `.txt`, `.md`, `.csv`, `.html` | Inlined as text in the prompt | **Size limit:** 20 MB per file. ## CLI Usage Use `--attach` (or `-A`) to attach files or URLs to a prompt. The flag is repeatable. ```bash # Single file initrunner run role.yaml -p "Describe this image" -A photo.png # Multiple files initrunner run role.yaml -p "Compare these" -A before.png -A after.png # URL attachment initrunner run role.yaml -p "What's in this image?" -A https://example.com/photo.jpg # Mixed files and URLs initrunner run role.yaml -p "Summarize" -A report.pdf -A https://example.com/chart.png ``` `--attach` requires `-p` (or piped stdin). Without a prompt, the command exits with an error. ## Interactive REPL In interactive mode (`-i`), three commands manage attachments: | Command | Description | |---------|-------------| | `/attach ` | Queue a file or URL for the next prompt | | `/attachments` | List queued attachments | | `/clear-attachments` | Clear all queued attachments | Queued attachments are sent with your next message and then cleared automatically. ``` > /attach diagram.png Queued attachment: diagram.png > /attach notes.pdf Queued attachment: notes.pdf > /attachments 1. diagram.png 2. notes.pdf > What do these show? [assistant response with both attachments] > /attachments No attachments queued. ``` ## Server API (OpenAI Format) The `initrunner serve` endpoint accepts multimodal content in the standard OpenAI format. The `content` field of a `ChatMessage` can be a string or a list of content parts. ### Content Part Types | Type | Field | Description | |------|-------|-------------| | `text` | `text` | Plain text content | | `image_url` | `image_url` | Image via HTTP URL or base64 `data:` URI | | `input_audio` | `input_audio` | Audio as base64 with format specifier | ### Image via URL ```bash curl http://127.0.0.1:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "messages": [{ "role": "user", "content": [ {"type": "text", "text": "What is in this image?"}, {"type": "image_url", "image_url": {"url": "https://example.com/photo.jpg"}} ] }] }' ``` ### Image via Base64 ```bash curl http://127.0.0.1:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "messages": [{ "role": "user", "content": [ {"type": "text", "text": "Describe this image."}, {"type": "image_url", "image_url": {"url": "data:image/png;base64,iVBORw0KGgo..."}} ] }] }' ``` ### Audio Input ```bash curl http://127.0.0.1:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "messages": [{ "role": "user", "content": [ {"type": "text", "text": "Transcribe this audio."}, {"type": "input_audio", "input_audio": {"data": "", "format": "mp3"}} ] }] }' ``` The `format` field defaults to `"mp3"` if omitted. ### OpenAI Python SDK ```python from openai import OpenAI client = OpenAI(base_url="http://127.0.0.1:8000/v1", api_key="unused") response = client.chat.completions.create( model="my-agent", messages=[{ "role": "user", "content": [ {"type": "text", "text": "What is in this image?"}, {"type": "image_url", "image_url": {"url": "https://example.com/photo.jpg"}}, ], }], ) print(response.choices[0].message.content) ``` ## Web Dashboard The chat interface supports file uploads via a button or drag-and-drop. **Upload flow:** 1. Files are uploaded to `POST /roles/{role_id}/chat/upload` and staged in memory 2. The server returns a list of attachment IDs 3. Attachment IDs are passed to the SSE stream endpoint with the next prompt 4. Staged files expire after **5 minutes** if unused **Limits:** 20 MB per file, same supported file types as the CLI. ## TUI In the TUI chat panel, press `Ctrl+A` to attach a file. The same file type restrictions and 20 MB size limit apply. ## Model Support Not all models support all modalities. If a model doesn't support a given content type, the provider API will return an error. | Modality | Example models | |----------|---------------| | Images | `gpt-4o`, `gpt-4o-mini`, `claude-sonnet-4-5-20250929`, `gemini-2.0-flash` | | Audio | `gpt-4o-audio-preview` | | Video | `gemini-2.0-flash` | | Documents (PDF) | `gpt-4o`, `claude-sonnet-4-5-20250929`, `gemini-2.0-flash` | When in doubt, use `gpt-4o` or a Claude model for broad multimodal support. ## Error Handling | Condition | Error | |-----------|-------| | File not found | `Attachment file not found: ` | | No file extension | `Cannot determine file type — file has no extension: ` | | Unsupported extension | `Unsupported file type '' for: . Supported: ...` | | File exceeds 20 MB | `File too large ( MB): . Maximum: 20 MB` | | Dashboard upload too large | `File too large: (max 20 MB)` (HTTP 400) | In the interactive REPL, attachment errors are printed and the prompt is not sent. In the CLI, the command exits with a non-zero status. ### Autonomous Mode # Autonomous Mode Autonomous mode lets an agent plan its own work, execute steps, adapt when things go wrong, and signal completion — all without human input. It's enabled by the `spec.autonomy` section and the `-a` CLI flag. ## How It Works An autonomous agent follows a plan-execute-adapt loop: ```mermaid flowchart TD Start([Start]) --> Plan[Create Plan] Plan --> Execute[Execute Step] Execute --> Check{Check Result} Check -->|Success| Done{More Steps?} Check -->|Failure| Adapt[Adapt Plan] Adapt --> Execute Done -->|Yes| Execute Done -->|No| Finish([finish_task]) ``` 1. **Plan** — The agent calls `update_plan` to create a step-by-step checklist 2. **Execute** — It works through each step using its tools 3. **Adapt** — If a step fails, the agent modifies its plan (add retries, skip, investigate) 4. **Finish** — The agent calls `finish_task` with a status when all steps are complete Two tools are auto-registered when autonomy is enabled: | Tool | Description | |------|-------------| | `update_plan(steps)` | Create or update the execution plan. Each step has a description and status (pending, in_progress, completed, failed) | | `finish_task(status, summary)` | Signal task completion with an overall status and summary | ## Loop Mechanics Each autonomous run follows a precise iteration sequence: 1. **Iteration 1** — The agent receives the user prompt plus the system prompt. It calls `update_plan` to create its initial plan, then begins executing the first step. 2. **Iterations 2+** — The `continuation_prompt` is injected with the current `ReflectionState` (plan progress, completed steps, failures). The agent continues executing, adapting, or re-planning. 3. **History trimming and compaction** — When conversation messages exceed `max_history_messages`, the oldest messages are dropped (keeping the system prompt and the most recent messages). Alternatively, enable [history compaction](#history-compaction) to LLM-summarize old messages before trimming, preserving key context. This prevents context window exhaustion on long runs. 4. **Budget check** — Before each iteration, the runner checks `autonomous_token_budget`, `max_iterations`, and `autonomous_timeout_seconds`. If any limit is reached, the loop terminates. 5. **Terminal conditions** — The loop ends when: - The agent calls `finish_task` (status: `completed`) - Any guardrail limit is hit (status: `max_iterations`, `budget_exceeded`, or `timeout`) - The agent reports it is stuck (status: `blocked` or `failed`) - An unrecoverable error occurs (status: `error`) 6. **Rate limiting** — If `iteration_delay_seconds` is set (> 0), the runner sleeps between iterations to avoid API rate limits. 7. **Result** — The final `ReflectionState` is returned with the terminal status, the plan steps (with their statuses), and the agent's summary. ## Example: Deployment Checker A complete autonomous agent that verifies deployments: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: deployment-checker description: Autonomous deployment verification agent tags: [devops, autonomous, deployment] spec: role: | You are a deployment verification agent. When given one or more URLs to check, create a verification plan, execute each step, and produce a pass/fail report. Workflow: 1. Use update_plan to create a checklist — one step per URL to verify 2. Run curl -sSL -o /dev/null -w "%{http_code} %{time_total}s" for each URL 3. Mark each step passed (2xx) or failed (anything else) 4. If a check fails, adapt your plan — add a retry or investigation step 5. When done, send a Slack summary with pass/fail results per URL 6. Call finish_task with the overall status Keep each plan step concise. Mark steps completed/failed as you go. model: provider: openai name: gpt-4o-mini temperature: 0.0 tools: - type: shell allowed_commands: - curl require_confirmation: false timeout_seconds: 30 - type: slack webhook_url: "${SLACK_WEBHOOK_URL}" default_channel: "#deployments" username: Deploy Checker icon_emoji: ":white_check_mark:" autonomy: max_plan_steps: 6 max_history_messages: 20 iteration_delay_seconds: 1 max_scheduled_per_run: 1 guardrails: max_iterations: 6 autonomous_token_budget: 30000 max_tokens_per_run: 10000 max_tool_calls: 15 session_token_budget: 100000 ``` ```bash initrunner run deployment-checker.yaml -a \ -p "Verify https://api.example.com/health and https://api.example.com/ready" ``` ## Configuration The `spec.autonomy` section controls planning behavior: | Field | Type | Default | Description | |-------|------|---------|-------------| | `max_plan_steps` | `int` | `20` | Maximum steps allowed in a plan | | `max_history_messages` | `int` | `40` | Messages kept in context during iteration | | `iteration_delay_seconds` | `int` | `0` | Pause between iterations (prevents tight loops) | | `continuation_prompt` | `str` | `"Continue working on the task..."` | Prompt injected at each iteration to keep the agent on track | | `max_scheduled_per_run` | `int` | `3` | Maximum follow-up tasks scheduled per autonomous run | | `max_scheduled_total` | `int` | `50` | Maximum total scheduled tasks across all runs | | `max_schedule_delay_seconds` | `int` | `86400` | Maximum delay allowed when scheduling a follow-up (seconds) | | `compaction.enabled` | `bool` | `false` | Enable LLM-driven summarization of old messages before trimming | | `compaction.threshold` | `int` | `30` | Minimum message count before compaction activates | | `compaction.tail_messages` | `int` | `6` | Number of recent messages to keep verbatim (not summarized) | | `compaction.model_override` | `str \| null` | `null` | Model to use for summarization. Defaults to the role's model | | `compaction.summary_prefix` | `str` | `"[CONVERSATION HISTORY SUMMARY]\n"` | Prefix prepended to the LLM summary | ## History Compaction Long-running autonomous agents can lose important context when older messages are dropped by simple history trimming. History compaction solves this by using an LLM call to summarize older messages before they are trimmed, preserving key decisions, tool results, and open tasks. ### Configuration ```yaml spec: autonomy: compaction: enabled: true threshold: 30 tail_messages: 6 model_override: "openai:gpt-4o-mini" summary_prefix: "[CONVERSATION HISTORY SUMMARY]\n" ``` ### How It Works After each iteration, if `compaction.enabled` is `true` and the conversation history exceeds `compaction.threshold` messages: 1. The most recent `tail_messages` messages are set aside (kept verbatim). 2. All older messages (except the first message, which is always preserved) are sent to an LLM for summarization. 3. The summary replaces the old messages as a single message, prefixed with `summary_prefix`. 4. Normal history trimming (`max_history_messages`) runs after compaction. ### Behavior - **Fail-open** — if the summarization LLM call fails, the original history is kept and trimming proceeds normally. Errors are logged but never crash the loop. - **Threshold-based** — compaction only activates when message count exceeds `threshold`, avoiding unnecessary LLM calls on short runs. - **Tail preservation** — the `tail_messages` most recent messages are never summarized, ensuring the agent always has full fidelity on its latest actions. - **Model flexibility** — use `model_override` to route summarization to a cheaper or faster model (e.g. `gpt-4o-mini`) to save tokens on the primary model. See the [`long-running-analyst`](/docs/examples#long-running-analyst) example for a complete configuration using compaction. ## Guardrails Autonomous agents need spending limits since they run without human oversight. These fields in `spec.guardrails` control resource usage: | Field | Type | Default | Scope | Description | |-------|------|---------|-------|-------------| | `max_iterations` | `int` | `10` | per-run | Maximum plan-execute-adapt cycles | | `autonomous_token_budget` | `int \| null` | `null` | per-run | Token budget for the autonomous run | | `autonomous_timeout_seconds` | `int \| null` | `null` | per-run | Wall-clock timeout for the entire autonomous run | | `max_tokens_per_run` | `int` | `50000` | per-iteration | Maximum output tokens consumed per iteration | | `max_tool_calls` | `int` | `20` | per-iteration | Maximum tool invocations per iteration | | `timeout_seconds` | `int` | `300` | per-iteration | Wall-clock timeout per iteration | | `max_request_limit` | `int \| null` | `auto` | per-iteration | Maximum LLM API round-trips per iteration. Auto-derived as `max(max_tool_calls + 10, 30)` | | `session_token_budget` | `int \| null` | `null` | session | Cumulative token budget for REPL session | | `daemon_token_budget` | `int \| null` | `null` | daemon | Lifetime token budget for the daemon process | | `daemon_daily_token_budget` | `int \| null` | `null` | daemon | Daily token budget — resets at UTC midnight | | `max_scheduled_per_run` | `int` | `3` | scheduling | Maximum follow-up tasks scheduled per autonomous run | | `max_scheduled_total` | `int` | `50` | scheduling | Maximum total scheduled tasks across all runs | When any limit is hit, the agent stops and reports its progress. See [Guardrails](/docs/guardrails) for full enforcement behavior, daemon budgets, and all available limits. ## Scheduling Tools When autonomy is combined with daemon mode, two additional tools are auto-registered for scheduling follow-up tasks: | Tool | Description | |------|-------------| | `schedule_followup(prompt, delay_seconds)` | Schedule a follow-up task to run after a delay (in seconds) | | `schedule_followup_at(prompt, iso_datetime)` | Schedule a follow-up task at a specific ISO 8601 datetime | Both tools are limited by `max_scheduled_per_run` and `max_scheduled_total` from the autonomy config. Scheduled follow-ups always run in autonomous mode. **Note:** Scheduled tasks are in-memory only and are lost on daemon restart. ```yaml autonomy: max_scheduled_per_run: 3 max_scheduled_total: 50 max_schedule_delay_seconds: 86400 # max 24 hours ``` ## Trigger Autonomous Flag Each trigger type (`cron`, `file_watch`, `webhook`) supports an `autonomous: true` flag. When set, that trigger fires in autonomous mode — the agent plans, executes, and finishes without human input. ```yaml triggers: - type: cron schedule: "0 */6 * * *" prompt: "Check system health and remediate issues." autonomous: true # this trigger runs in autonomous mode - type: file_watch paths: ["./reports"] extensions: [".csv"] prompt_template: "Process new report: {path}" autonomous: true ``` Scheduled follow-ups (via `schedule_followup` / `schedule_followup_at`) always run in autonomous mode regardless of this flag. ## CLI Flags | Flag | Description | |------|-------------| | `-a`, `--autonomous` | Enable autonomous mode for this run | | `--max-iterations N` | Override `max_iterations` from the YAML | ```bash # Enable autonomous mode initrunner run role.yaml -a -p "Check all endpoints" # Override max iterations initrunner run role.yaml -a --max-iterations 3 -p "Quick check" ``` ## Reflection State At each iteration, the agent's current state is captured as a `ReflectionState` and injected into the continuation prompt. This gives the agent awareness of what it has accomplished and what remains. `ReflectionState` contains: | Field | Type | Description | |-------|------|-------------| | `completed` | `bool` | Whether the agent has called `finish_task` | | `summary` | `str` | Running summary of progress | | `status` | `str` | Current status label | | `steps` | `list[PlanStep]` | The current plan steps | Each `PlanStep` has: | Field | Type | Description | |-------|------|-------------| | `description` | `str` | What this step does | | `status` | `str` | One of: `pending`, `in_progress`, `completed`, `failed`, `skipped` | | `notes` | `str` | Optional notes (error details, results, etc.) | The reflection state is rendered as a summary and appended to the `continuation_prompt` at the start of each iteration, so the agent always has context about its progress. ## Memory Integration Autonomous mode integrates with the [Memory](/docs/memory) system for persistence and recall: - **Session save (`--resume`)** — When memory is configured and the agent is run with `--resume`, the conversation history (including plan steps and tool outputs) is saved at the end of the run. The next `--resume` invocation restores context so the agent can pick up where it left off. - **`finish_task` episodic capture** — When the agent calls `finish_task`, the summary is persisted as an episodic memory with category `autonomous_run` (if episodic memory is enabled). This allows future runs or other agents to recall past outcomes. - **`recall` tool** — If memory is enabled, the `recall` tool is auto-registered. The agent can search all memory types (semantic, episodic, procedural) for past results, patterns, and decisions. Pass `memory_types` to filter by type. This is useful for agents that run repeatedly (e.g., via cron triggers) and need to avoid repeating past work. - **Consolidation on exit** — When `consolidation.interval` is `after_autonomous`, consolidation runs automatically after the autonomous loop exits, extracting durable semantic facts from episodic records. See [Memory: Consolidation](/docs/memory#consolidation). ## Terminal Statuses When an autonomous run ends, it produces a `final_status` indicating how it concluded: | Status | Description | Success? | |--------|-------------|----------| | `completed` | Agent called `finish_task` successfully | Yes | | `max_iterations` | Reached the `max_iterations` limit | Yes | | `blocked` | Agent is stuck and cannot proceed | No | | `failed` | Agent encountered a failure it couldn't recover from | No | | `budget_exceeded` | Token budget exhausted | No | | `timeout` | `autonomous_timeout_seconds` elapsed | No | | `error` | Unexpected error during execution | No | `completed` and `max_iterations` are considered successful outcomes. All others indicate the run did not finish its intended work. ## When to Use Autonomous Mode **Good fit:** - Verification tasks (deployment checks, health audits) - Batch processing (process a list of items with per-item steps) - Multi-step investigations (diagnose an issue, try fixes) - Tasks with clear completion criteria **Consider alternatives:** - Recurring tasks → use [Triggers](/docs/triggers) with `daemon` mode instead - Multi-agent workflows → use [Compose](/docs/compose) for coordination - Interactive exploration → use REPL mode (`-i`) for human-in-the-loop ## Troubleshooting ### Agent never calls `finish_task` **Cause:** The system prompt doesn't instruct the agent to call `finish_task`, or the agent gets stuck in an adapt loop creating new steps indefinitely. **Fix:** Explicitly instruct the agent to call `finish_task` in `spec.role`. Set `max_iterations` and `max_plan_steps` to enforce hard stops. The `max_iterations` terminal status is still considered a successful outcome. ### Token budget exceeded **Cause:** The autonomous token budget is too small for the task, or the agent is producing verbose tool outputs that consume tokens quickly. **Fix:** Increase `autonomous_token_budget` or reduce per-iteration output by lowering `model.max_tokens`. Check if shell or HTTP tools are returning large outputs — tool output limits (see [Guardrails](/docs/guardrails#tool-output-limits)) apply automatically, but the agent may be making too many calls. Reduce `max_tool_calls` to limit per-iteration tool usage. ### Scheduled tasks lost on daemon restart **Cause:** Scheduled follow-ups (via `schedule_followup` / `schedule_followup_at`) are stored in-memory only. When the daemon process restarts, all pending scheduled tasks are lost. **Fix:** Use cron triggers for recurring tasks instead of `schedule_followup`. For critical follow-ups, have the agent write the schedule to a file or external system (e.g., a database) and use a cron trigger to check for pending work. ### Agent makes no tool calls **Cause:** The model is responding with text-only messages instead of invoking tools. This typically happens when the system prompt is too vague, or when `max_tool_calls` is set to `0`. **Fix:** Verify `max_tool_calls` is greater than `0`. Make the system prompt explicit about which tools to use and when. Add example workflows in `spec.role` that reference tool names directly. ### Structured Output # Structured Output Structured output lets agents return validated JSON instead of free-form text. Define a JSON Schema in `spec.output` and the agent's response is guaranteed to match your schema — parsed, validated, and returned as JSON. This is useful for pipelines, automation, and any scenario where downstream code needs to consume agent output programmatically. ## Quick Example ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: invoice-classifier description: Classifies invoices and extracts structured data spec: role: | You are an invoice classifier. Given a description of an invoice, extract the relevant fields and return structured JSON. model: provider: openai name: gpt-4o-mini temperature: 0.0 output: type: json_schema schema: type: object properties: status: type: string enum: [approved, rejected, needs_review] amount: type: number description: Invoice amount in USD vendor: type: string required: [status, amount, vendor] ``` ```bash initrunner run invoice-classifier.yaml -p "Acme Corp invoice for $250 for office supplies" # → {"status": "approved", "amount": 250.0, "vendor": "Acme Corp"} ``` ## Configuration Structured output is configured in the `spec.output` section: ```yaml spec: output: type: json_schema # "text" (default) or "json_schema" schema: { ... } # inline JSON Schema (mutually exclusive with schema_file) schema_file: schema.json # path to external JSON Schema file ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `type` | `str` | `"text"` | Output type. `"text"` for free-form text, `"json_schema"` for validated JSON. | | `schema` | `dict` | `null` | Inline JSON Schema definition. Required when `type` is `json_schema` (unless `schema_file` is set). | | `schema_file` | `str` | `null` | Path to an external JSON Schema file. Relative paths are resolved from the role file's directory. | When `type` is `json_schema`, exactly one of `schema` or `schema_file` must be provided. ## Supported Types | JSON Schema Type | Python Type | Notes | |-----------------|-------------|-------| | `string` | `str` | Plain string | | `string` + `enum` | `Literal[...]` | Constrained to listed values | | `number` | `float` | Floating-point number | | `integer` | `int` | Integer number | | `boolean` | `bool` | True/false | | `object` | nested `BaseModel` | Recursive — nested objects become nested models | | `array` | `list[ItemType]` | Item type resolved from `items` schema | ## Schema Keywords - **`properties`** — defines the fields of an object - **`required`** — list of field names that must be present (non-required fields become `Optional` with `None` default) - **`description`** — field-level documentation passed to the model - **`enum`** — constrains a string field to specific values - **`items`** — defines the element type for arrays ## Nested Objects & Arrays ```yaml spec: output: type: json_schema schema: type: object properties: title: type: string description: Report title sections: type: array items: type: object properties: heading: type: string body: type: string required: [heading, body] metadata: type: object properties: author: type: string tags: type: array items: type: string required: [title, sections] ``` ## External Schema File For larger schemas, use `schema_file` to reference a separate JSON file: ```yaml spec: output: type: json_schema schema_file: schemas/invoice.json ``` The file must contain a valid JSON Schema object. Relative paths are resolved from the role YAML file's directory. Absolute paths are used as-is. ```json { "type": "object", "properties": { "status": { "type": "string", "enum": ["approved", "rejected"] }, "amount": { "type": "number" } }, "required": ["status", "amount"] } ``` ## Pipeline Precedence When using [compose](/docs/compose) pipelines, a pipeline step's `output_format` overrides the role-level `spec.output` config. This allows the same role to produce different output formats depending on the pipeline context. ## Limitations Structured output requires non-streaming execution. If you attempt to use streaming (`execute_run_stream`) with a `json_schema` output type, a `ValueError` is raised: ``` Streaming is not supported with structured output (output.type='json_schema'). Use non-streaming execution instead. ``` Use `initrunner run` (single-shot) or non-streaming mode for structured output agents. See also: [Guardrails](/docs/guardrails) for enforcing resource limits on structured output agents, [Compose](/docs/compose) for pipeline-level output overrides. ### Report Export # Report Export InitRunner can export a structured markdown report after any `run` command. Reports capture the prompt, output, token usage, timing, and status — useful for PR reviews, changelog generation, CI analysis, or any workflow where you need a persistent artifact from an agent run. ## Quick Start ```bash # Export a report after a run initrunner run role.yaml -p "Review this PR" --export-report # Custom output path initrunner run role.yaml -p "Review this PR" --export-report --report-path ./review.md # Use a purpose-built template initrunner run role.yaml -p "Review this PR" --export-report --report-template pr-review # Combine with --dry-run for testing initrunner run role.yaml -p "Hello" --dry-run --export-report ``` Reports are always written regardless of whether the run succeeds or fails. A failed run produces a report with the error details. ## CLI Options These flags are available on the `run` command: | Option | Type | Default | Description | |--------|------|---------|-------------| | `--export-report` | `bool` | `false` | Export a markdown report after the run. | | `--report-path` | `Path` | `initrunner-report.md` | Output file path for the report. | | `--report-template` | `str` | `default` | Report template to use: `default`, `pr-review`, `changelog`, `ci-fix`. | ## Templates Four built-in templates are included. All receive the same data — they differ in layout and emphasis. ### `default` Full report with header, prompt, output, metrics table, and iteration breakdown (if autonomous). Best for general-purpose use. ```bash initrunner run role.yaml -p "Summarize this" --export-report ``` ### `pr-review` Compact layout with a "PR Review Report" header. The agent output is presented as the review body. Metrics are shown in a single-row table. ```bash initrunner run role.yaml -p "Review the changes in this diff" \ --export-report --report-template pr-review ``` ### `changelog` "Changelog Report" header with the output as changelog content. Compact metrics. ```bash initrunner run role.yaml -p "Generate a changelog from these commits" \ --export-report --report-template changelog ``` ### `ci-fix` "CI Fix Analysis" header with iteration details (especially useful with `--autonomous`), followed by output and metrics. ```bash initrunner run role.yaml -p "Fix the failing CI tests" \ -a --export-report --report-template ci-fix ``` ## Report Contents Every report includes: | Field | Description | |-------|-------------| | Agent name | From `metadata.name` in the role YAML | | Model | Provider and model name (e.g. `openai:gpt-5-mini`) | | Run ID | Unique identifier for the run | | Timestamp | ISO 8601 UTC timestamp | | Status | `Success` or `Failed` | | Mode | `dry-run` or `autonomous` (if applicable) | | Prompt | The input prompt text | | Output | The agent's response (or error message on failure) | | Tokens In/Out/Total | Token usage metrics | | Tool Calls | Number of tool invocations | | Duration | Wall-clock time in milliseconds | For autonomous runs (`-a`), the `default` and `ci-fix` templates also include per-iteration breakdowns showing tokens, tool calls, duration, and a preview of each iteration's output. ## Behaviour - **Always exports**: Reports are written whether the run succeeds or fails. Failed runs include the error message. - **Early validation**: An unknown template name is a hard error before execution — the agent never runs. - **Export failures are warnings**: If report writing fails (e.g. permission denied), a warning is printed but the run exit code is not affected. - **Works with all run modes**: Single-shot (`-p`), autonomous (`-a`), and interactive with initial prompt (`-p -i`). For `-p -i`, the report captures the initial prompt/response before entering interactive mode. ## Examples ### PR review with custom path ```bash initrunner run code-reviewer.yaml \ -p "Review the diff in review.patch" \ -A review.patch \ --export-report \ --report-template pr-review \ --report-path ./pr-review-report.md ``` ### CI fix with autonomous mode ```bash initrunner run ci-fixer.yaml \ -p "The build is failing on test_auth. Fix it." \ -a --max-iterations 5 \ --export-report \ --report-template ci-fix \ --report-path /tmp/ci-analysis.md ``` ### Dry-run report for testing ```bash initrunner run role.yaml -p "Hello" --dry-run --export-report cat initrunner-report.md ``` ## Programmatic Usage The report module can be used directly from Python: ```python from initrunner.report import build_report_context, render_report, export_report # Build context from a run result context = build_report_context(role, result, prompt, dry_run=False) # Render to string markdown = render_report(context, template_name="pr-review") # Or export directly to file path = export_report(role, result, prompt, Path("report.md"), template_name="default", dry_run=False) ``` The `services.py` layer also provides `export_run_report_sync()` for use from the API or TUI. ## Automation & Orchestration ### Triggers # Triggers Triggers allow agents to run automatically in response to events — cron schedules, file changes, incoming webhooks, or messaging platforms. They are configured in `spec.triggers` and activated with the `initrunner daemon` command. ```mermaid flowchart LR subgraph Events CR[Cron Schedule] FW[File Watcher] WH[Webhook] HB[Heartbeat] TG[Telegram] DC[Discord] end D[Daemon] AG[Agent Run] subgraph Output SK[Sinks] AU[Audit Log] end CR --> D FW --> D WH --> D HB --> D TG --> D DC --> D D --> AG AG --> SK AG --> AU ``` ## Trigger Types | Type | Description | |------|-------------| | `cron` | Fire on a cron schedule | | `file_watch` | Fire when files change in watched directories | | `webhook` | Fire on incoming HTTP requests (localhost only) | | `heartbeat` | Fire on a fixed interval, processing a markdown checklist file | | `telegram` | Respond to Telegram messages via long-polling (outbound only) | | `discord` | Respond to Discord DMs and @mentions via WebSocket (outbound only) | ## Quick Example ```yaml spec: triggers: - type: cron schedule: "0 9 * * 1" prompt: "Generate weekly status report." - type: file_watch paths: ["./watched"] extensions: [".md", ".txt"] prompt_template: "File changed: {path}. Summarize the changes." - type: webhook path: /webhook port: 8080 secret: ${WEBHOOK_SECRET} - type: heartbeat file: ./tasks.md interval_seconds: 3600 active_hours: [9, 17] ``` ```bash initrunner daemon role.yaml ``` ## Cron Trigger Fires the agent on a cron schedule. ```yaml triggers: - type: cron schedule: "0 9 * * 1" prompt: "Generate weekly status report." timezone: UTC ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `schedule` | `str` | *(required)* | Cron expression (5-field: `min hour day month weekday`) | | `prompt` | `str` | *(required)* | Prompt sent to the agent when the trigger fires | | `timezone` | `str` | `"UTC"` | Timezone for schedule evaluation | ### Schedule Examples | Expression | Meaning | |-----------|---------| | `"0 9 * * 1"` | Every Monday at 9:00 AM | | `"*/5 * * * *"` | Every 5 minutes | | `"0 0 1 * *"` | First day of every month at midnight | | `"30 14 * * 1-5"` | Weekdays at 2:30 PM | ## File Watch Trigger Fires when files change in watched directories using [watchfiles](https://watchfiles.helpmanual.io/). ```yaml triggers: - type: file_watch paths: ["./watched", "./data"] extensions: [".md", ".txt"] prompt_template: "File changed: {path}. Summarize." debounce_seconds: 1.0 process_existing: false ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `paths` | `list[str]` | *(required)* | Directories to watch | | `extensions` | `list[str]` | `[]` | File extensions to filter (empty = all) | | `prompt_template` | `str` | `"File changed: {path}"` | Template with `{path}` placeholder | | `debounce_seconds` | `float` | `1.0` | Debounce interval | | `process_existing` | `bool` | `false` | Fire once for each matching file already present on startup | ## Webhook Trigger Fires when an HTTP request is received on a local endpoint. Useful for GitHub webhooks, CI/CD systems, or HTTP callbacks. ```yaml triggers: - type: webhook path: /webhook port: 8080 method: POST secret: ${WEBHOOK_SECRET} ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `path` | `str` | `"/webhook"` | URL path to listen on | | `port` | `int` | `8080` | Port to listen on | | `method` | `str` | `"POST"` | HTTP method to accept | | `secret` | `str \| null` | `null` | HMAC secret for `X-Hub-Signature-256` verification | ### HMAC Verification When `secret` is set, requests must include a valid `X-Hub-Signature-256` header (GitHub-compatible HMAC-SHA256). Invalid or missing signatures return `403 Forbidden`. ### Example: GitHub Webhook ```yaml triggers: - type: webhook path: /github port: 9000 secret: ${GITHUB_WEBHOOK_SECRET} ``` ```bash curl -X POST http://127.0.0.1:9000/github \ -H "Content-Type: application/json" \ -H "X-Hub-Signature-256: sha256=..." \ -d '{"action": "opened", "pull_request": {"title": "Fix bug"}}' ``` ## Heartbeat Trigger Fires on a fixed interval, reading a markdown checklist file and prompting the agent with any unchecked items. Useful for batching multiple periodic tasks into a single trigger instead of separate cron entries. ```yaml triggers: - type: heartbeat file: ./tasks.md # required interval_seconds: 3600 # default: 3600 (1 hour) autonomous: true # default: false active_hours: [9, 17] # default: null (always active) timezone: America/New_York # default: UTC ``` ### Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `file` | `str` | *(required)* | Path to the markdown checklist file | | `interval_seconds` | `int` | `3600` | Seconds between heartbeat checks. Must be > 0 | | `prompt_prefix` | `str` | `"You are processing a periodic task checklist..."` | Text prepended to the checklist content in the prompt | | `active_hours` | `list[int] \| null` | `null` | Two-element list `[start, end]` defining active hours (0-23). `null` means always active | | `timezone` | `str` | `"UTC"` | Timezone for `active_hours` evaluation. Must be a valid IANA timezone (e.g. `America/New_York`) | ### Active Hours When `active_hours` is set, the trigger only fires during the specified window: - **Normal window** (e.g. `[9, 17]`): fires when `start <= hour < end` - **Midnight-spanning** (e.g. `[22, 6]`): fires when `hour >= start` or `hour < end` - **Always active**: omit `active_hours` or set to `null` ### Behavior - The first heartbeat fires after one full interval from daemon startup (not immediately). - On each heartbeat, the file is read (capped at 64KB with `[truncated]` marker). - Unchecked items (`- [ ]`) are counted. If there are zero open items, no event is fired. - The prompt is composed as: `prompt_prefix + "\n\n" + file_content`. - The trigger event includes `metadata: {"file": "...", "item_count": "...", "interval_seconds": "..."}`. ### Example Checklist ```markdown # Daily Tasks - [ ] Check deployment health - [x] Review overnight alerts - [ ] Update documentation - [ ] Run integration tests ``` No new dependencies — uses stdlib `zoneinfo` (Python 3.9+). ## Telegram Trigger Responds to Telegram messages using long-polling via [python-telegram-bot](https://python-telegram-bot.org/). Outbound HTTPS only — no ports opened, no inbound connections required. ### Setup 1. Create a bot with [@BotFather](https://t.me/BotFather) and copy the token. 2. Set the token: `export TELEGRAM_BOT_TOKEN=your-token` (or add it to `~/.initrunner/.env`). 3. Install the optional dependency: `pip install initrunner[telegram]`. ```yaml triggers: - type: telegram token_env: TELEGRAM_BOT_TOKEN # default allowed_users: ["alice", "bob"] # empty = allow all prompt_template: "{message}" # default ``` ### Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `token_env` | `str` | `"TELEGRAM_BOT_TOKEN"` | Environment variable holding the bot token. | | `allowed_users` | `list[str]` | `[]` | Telegram usernames allowed to interact. Empty list allows all users. | | `prompt_template` | `str` | `"{message}"` | Template for the prompt. `{message}` is replaced with the user's message text. | ### Behavior - Uses long-polling (outbound HTTPS) — no ports opened, no webhooks to configure. - Only text messages are processed (commands like `/start` are ignored). - When `allowed_users` is set, messages from other users are silently dropped. - The agent's response is sent back to the originating chat, automatically chunked to Telegram's 4096-character message limit. - Chunks are split at newline boundaries when possible for cleaner output. - The trigger event includes `metadata: {"user": "...", "chat_id": "..."}`. ### Security - **Store the bot token securely** — use environment variables or a secrets manager, never commit it to version control. - **Use `allowed_users`** to restrict access to known usernames. An empty list means anyone can interact with the bot. - **Set `daemon_daily_token_budget`** in guardrails to prevent runaway costs. For the full quickstart walkthrough, see [Telegram Bot](/docs/telegram). ## Discord Trigger Responds to Discord DMs and @mentions via WebSocket client using [discord.py](https://discordpy.readthedocs.io/). Outbound only — no ports opened. ### Setup 1. Create a bot in the [Discord Developer Portal](https://discord.com/developers/applications). 2. Enable the **Message Content Intent** under Bot settings. 3. Invite the bot to your server with the `bot` scope and `Send Messages` + `Read Message History` permissions. 4. Set the token: `export DISCORD_BOT_TOKEN=your-token` (or add it to `~/.initrunner/.env`). 5. Install the optional dependency: `pip install initrunner[discord]`. ```yaml triggers: - type: discord token_env: DISCORD_BOT_TOKEN # default channel_ids: ["123456789"] # empty = all channels allowed_roles: ["Admin", "Bot-User"] # empty = all roles prompt_template: "{message}" # default ``` ### Options | Field | Type | Default | Description | |-------|------|---------|-------------| | `token_env` | `str` | `"DISCORD_BOT_TOKEN"` | Environment variable holding the bot token. | | `channel_ids` | `list[str]` | `[]` | Channel IDs to respond in. Empty list allows all channels. | | `allowed_roles` | `list[str]` | `[]` | Role names required to interact. Empty list allows all users. | | `prompt_template` | `str` | `"{message}"` | Template for the prompt. `{message}` is replaced with the user's message text. | ### Behavior - Uses WebSocket client connection — outbound only, no ports opened. - Responds to **DMs** and **@mentions** only (not every message in every channel). - When `allowed_roles` is set, **DMs are denied** (DMs have no role context, so allowing them would bypass the role filter). - Bot @mention is stripped from the message content using the mention ID pattern for robustness. - The agent's response is sent back to the originating channel, automatically chunked to Discord's 2000-character message limit. - The trigger event includes `metadata: {"user": "...", "channel_id": "..."}`. ### Security - **Store the bot token securely** — never commit it to version control. - **Use `channel_ids`** to restrict the bot to specific channels. - **Use `allowed_roles`** to restrict access to specific server roles. Note that DMs are automatically denied when roles are configured. - **Set `daemon_daily_token_budget`** in guardrails to prevent runaway costs. For the full quickstart walkthrough, see [Discord Bot](/docs/discord). ## Daemon Mode The `initrunner daemon` command starts all configured triggers and waits for events: ```bash initrunner daemon role.yaml initrunner daemon role.yaml --audit-db ./custom-audit.db initrunner daemon role.yaml --no-audit ``` | Option | Type | Default | Description | |--------|------|---------|-------------| | `role_file` | `Path` | *(required)* | Path to the role YAML file | | `--audit-db` | `Path` | `~/.initrunner/audit.db` | Audit database path | | `--no-audit` | `bool` | `false` | Disable audit logging | ### Lifecycle 1. The role is loaded and the agent is built. 2. All triggers are started in daemon threads via `TriggerDispatcher`. 3. When a trigger fires, the prompt is sent to the agent. 4. **Messaging triggers** (Telegram, Discord) always use the direct execution path — `autonomous: true` on the trigger config is ignored. The agent's reply is sent back to the originating channel immediately, *before* display, sinks, and episode capture run. 5. **Other triggers** (cron, file watch, webhook) use the autonomous loop when `autonomous: true` is set. The result is displayed and dispatched to sinks after the run completes. 6. The daemon continues until interrupted. ### Hot-Reload By default, the daemon watches the role YAML and referenced skill files for changes. When a change is detected, the role and agent are reloaded without restarting the daemon. ```yaml spec: daemon: hot_reload: true # default: true reload_debounce_seconds: 1.0 # default: 1.0 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `hot_reload` | `bool` | `true` | Enable file-watching for role YAML and skill files | | `reload_debounce_seconds` | `float` | `1.0` | Debounce interval (0-30 seconds) for batching rapid writes | **What reloads**: role YAML, skill files, model config, tools, triggers, autonomy config. **What does NOT reload** (requires daemon restart): memory store, audit logger, `.env` files, sink dispatcher configuration. **Fail-open policy**: if the reloaded YAML is invalid, the daemon keeps the last known-good config and logs a warning. **Thread safety**: in-flight trigger runs use a snapshot of the old agent/role. New runs after a reload use the updated config. Trigger dispatchers are restarted only if the trigger config actually changed. Hot-reload requires a `role_path` — it is automatically enabled when running `initrunner daemon role.yaml`. Ephemeral roles (e.g. from `initrunner chat`) do not support hot-reload. ### Trigger Events Every trigger fires a `TriggerEvent` containing: | Field | Type | Description | |-------|------|-------------| | `trigger_type` | `str` | `"cron"`, `"file_watch"`, `"webhook"`, `"heartbeat"`, `"telegram"`, or `"discord"` | | `prompt` | `str` | The prompt to send to the agent | | `timestamp` | `str` | ISO 8601 timestamp of when the event was created | | `metadata` | `dict[str, str]` | Type-specific metadata (schedule, path, user, etc.) | | `reply_fn` | `Callable \| None` | Optional callback to send the agent's response back to the originating channel | ### Signal Handling The daemon handles `SIGINT` (Ctrl+C) and `SIGTERM` for clean shutdown: 1. Sets a stop event 2. Stops all triggers 3. Joins trigger threads (5-second timeout) 4. Exits cleanly ### Sinks # Sinks Sinks define where agent output goes after a run completes. They are most useful in daemon mode and compose pipelines, where agents run unattended and their results need to be routed somewhere — a webhook, a file, a custom function, or another agent. Sinks are configured in the `spec.sinks` list. ## Quick Example ```yaml spec: sinks: - type: webhook url: https://hooks.slack.com/services/T.../B.../xxx headers: Content-Type: application/json - type: file path: ./output/results.json format: json ``` ## Sink Types | Type | Description | |------|-------------| | `webhook` | HTTP POST to a URL | | `file` | Write to a local file | | `custom` | Call a Python function | ## Webhook Sends a JSON payload to a URL via HTTP POST. Useful for Slack, Discord, PagerDuty, or any HTTP endpoint. ```yaml sinks: - type: webhook url: https://hooks.slack.com/services/T.../B.../xxx headers: Content-Type: application/json Authorization: Bearer ${WEBHOOK_TOKEN} timeout_seconds: 30 retry_count: 3 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `url` | `str` | *(required)* | Destination URL | | `method` | `str` | `"POST"` | HTTP method | | `headers` | `dict` | `{}` | HTTP headers (supports `${VAR}` substitution) | | `timeout_seconds` | `int` | `30` | Request timeout | | `retry_count` | `int` | `0` | Number of retry attempts on failure | ### Payload Format The webhook POST body is a JSON object: ```json { "agent_name": "monitor-agent", "run_id": "a1b2c3d4e5f6", "trigger_type": "cron", "status": "success", "output": "All 3 services healthy. Response times: api=120ms, web=85ms, db=45ms.", "timestamp": "2025-01-15T09:00:05Z", "tokens_used": 1250, "duration_ms": 4200 } ``` ## File Writes agent output to a local file. Supports JSON and plain text formats. ```yaml sinks: - type: file path: ./output/results.json format: json ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `path` | `str` | *(required)* | Output file path | | `format` | `str` | `"json"` | Output format: `"json"` or `"text"` | - **`json`** — writes a JSON object (same schema as webhook payload) - **`text`** — writes the raw output string ## Custom Calls a Python function with the run result. Use this for custom integrations — database writes, email, message queues, or anything else. ```yaml sinks: - type: custom module: my_sinks function: send_to_database ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `module` | `str` | *(required)* | Python module path (must be importable) | | `function` | `str` | *(required)* | Function name to call | The function signature: ```python def send_to_database(result: dict) -> None: """Called by InitRunner after each agent run. Args: result: Run result dict (same schema as webhook payload). """ # ... process result ``` ## Multiple Sinks An agent can have multiple sinks. All sinks fire after each run completes: ```yaml spec: sinks: # Log to file - type: file path: ./logs/runs.json format: json # Notify Slack - type: webhook url: ${SLACK_WEBHOOK_URL} # Store in database - type: custom module: my_sinks function: store_result ``` ## Sinks with Daemon Mode Sinks are most commonly used with [triggers](/docs/triggers) and daemon mode. When a trigger fires and an agent run completes, all configured sinks receive the result: ```yaml spec: triggers: - type: cron schedule: "0 */6 * * *" prompt: "Check system health and report status." sinks: - type: webhook url: ${SLACK_WEBHOOK_URL} - type: file path: ./logs/health-checks.json format: json ``` ```bash initrunner daemon role.yaml ``` Every 6 hours, the agent runs, and the output is sent to both Slack and the log file. ## Sinks with Compose In [compose](/docs/compose) pipelines, agent chaining is handled by the compose orchestration layer. See the compose documentation for multi-agent pipeline examples. ### Team Mode # Team Mode Team mode lets you define multiple personas in a single YAML file. Personas run sequentially — each one receives the prior persona's output as context, building a chain of perspectives on the same task. ```mermaid flowchart LR T[Task prompt] --> P1[Persona 1] P1 -->|output| P2[Persona 2] P2 -->|output| P3[Persona 3] P3 --> R[Final output] ``` Unlike [Compose](/docs/compose) (which wires separate agent services together), team mode keeps everything in one file with no delegate sinks, no `depends_on`, and no separate role YAMLs. ## Quick Start ```yaml # team.yaml apiVersion: initrunner/v1 kind: Team metadata: name: code-review-team description: Multi-perspective code review spec: model: provider: openai name: gpt-5-mini personas: architect: "review for design patterns, SOLID principles, and architecture issues" security: "find security vulnerabilities, injection risks, auth issues" maintainer: "check readability, naming, test coverage gaps, docs" tools: - type: filesystem root_path: . read_only: true - type: git repo_path: . read_only: true ``` ```bash initrunner validate team.yaml initrunner run team.yaml --task "review the auth module" ``` A prompt (`--task` or `-p`) is required. Interactive (`-i`) and autonomous (`-a`) modes are not supported for teams. ## How It Works 1. The runner loads the team file and validates it (`kind: Team`). 2. For each persona (in insertion order), a temporary agent is created with the persona's prompt as its system role. 3. The task prompt is sent to the first persona. Each subsequent persona receives the original task **plus** all prior outputs wrapped in `` XML tags. 4. Tools and guardrails are shared across all personas. 5. The final persona's output is returned as the team result. Prior outputs are wrapped in XML to mitigate prompt injection from earlier personas: ``` ...architect's review... ``` ## Team Definition | Field | Type | Required | Description | |-------|------|----------|-------------| | `apiVersion` | `str` | yes | `initrunner/v1` | | `kind` | `str` | yes | Must be `"Team"` | | `metadata.name` | `str` | yes | Team name (lowercase, hyphens) | | `metadata.description` | `str` | no | Human-readable description | | `spec.model` | `object` | yes | Model configuration (shared by all personas) | | `spec.personas` | `dict` | yes | Ordered map of persona name to system prompt | | `spec.tools` | `list` | no | Tools available to all personas | | `spec.guardrails` | `object` | no | Per-run and team-level guardrails | ## Personas Personas are defined as a YAML mapping where the key is the persona name and the value is the system prompt: ```yaml personas: researcher: "gather comprehensive information about the topic, listing key facts, sources, and different perspectives" fact-checker: "verify claims from the research, flag unsupported statements, and note confidence levels" writer: "synthesize the verified research into a clear, well-structured summary" ``` Personas run in insertion order — YAML preserves key order, so the order you write them is the order they execute. Each persona is a lightweight agent with its own system prompt but shared model, tools, and guardrails. ## Guardrails Team mode supports all standard [per-run guardrails](/docs/guardrails) plus two team-specific limits: | Field | Type | Default | Description | |-------|------|---------|-------------| | `team_token_budget` | `int` | `null` | Cumulative token budget across all personas. Pipeline stops if exceeded. | | `team_timeout_seconds` | `int` | `null` | Wall-clock limit for the entire team run. Pipeline stops if exceeded. | ```yaml guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 team_token_budget: 150000 team_timeout_seconds: 900 ``` `max_tokens_per_run` and `timeout_seconds` apply to **each persona individually**. `team_token_budget` and `team_timeout_seconds` apply to the **entire team run** across all personas. ## Audit Logging Team runs are logged with `trigger_type: "team"` in the audit database. Each persona's run is tracked individually with a shared `team_run_id` so you can correlate them: ```json { "trigger_type": "team", "team_run_id": "abc123", "persona": "architect", "tokens_used": 4200 } ``` Use `initrunner audit export` to inspect team run logs. ## Validation `initrunner validate` supports `kind: Team` files: ```bash initrunner validate team.yaml ``` It checks for valid persona names, model configuration, tool definitions, and guardrail values. ## Team vs Compose | | Team | Compose | |---|------|---------| | **File count** | One YAML | One compose YAML + one role YAML per service | | **Execution** | Sequential personas | Parallel services with delegate sinks | | **Data flow** | Automatic — prior output injected as context | Explicit — delegate sinks route between services | | **Model** | Shared across all personas | Each service has its own model | | **Use case** | Multiple perspectives on one task | Multi-service pipelines and workflows | Use team mode when you want multiple viewpoints on the same input. Use [Compose](/docs/compose) when you need independent services with different models, triggers, and routing. ## Examples ### Code Review Team Three personas review code from different angles: ```yaml apiVersion: initrunner/v1 kind: Team metadata: name: code-review-team description: Multi-perspective code review spec: model: provider: openai name: gpt-5-mini personas: architect: "review for design patterns, SOLID principles, and architecture issues" security: "find security vulnerabilities, injection risks, auth issues" maintainer: "check readability, naming, test coverage gaps, docs" tools: - type: filesystem root_path: . read_only: true - type: git repo_path: . read_only: true guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 team_token_budget: 150000 ``` ```bash initrunner run code-review-team.yaml --task "review the auth module" ``` ### Research Team Research a topic, verify claims, then produce a polished summary: ```yaml apiVersion: initrunner/v1 kind: Team metadata: name: research-team description: Research a topic and produce a polished summary spec: model: provider: openai name: gpt-5-mini personas: researcher: "gather comprehensive information about the topic, listing key facts, sources, and different perspectives" fact-checker: "verify claims from the research, flag unsupported statements, and note confidence levels" writer: "synthesize the verified research into a clear, well-structured summary" tools: - type: web_reader - type: datetime guardrails: max_tokens_per_run: 50000 timeout_seconds: 300 team_token_budget: 150000 team_timeout_seconds: 900 ``` ```bash initrunner run research-team.yaml --task "summarize the state of WebAssembly adoption in 2026" ``` ### Compose # Compose Agent Composer lets you define multiple agents as services in a single `compose.yaml` file, wire them together with delegate sinks, and run them all with one command. ```mermaid flowchart TD subgraph Tier 0 A[Service A] end subgraph Tier 1 B[Service B] C[Service C] end subgraph Tier 2 D[Service D] end A -->|delegate sink| B A -->|delegate sink| C B -->|delegate sink| D C -->|delegate sink| D ``` Services start in tiers based on `depends_on`. Each service is a standalone agent connected to others via delegate sinks — in-memory queues that route output from one agent to the next. ## Quick Start ```yaml # compose.yaml apiVersion: initrunner/v1 kind: Compose metadata: name: my-pipeline description: Simple producer-consumer pipeline spec: services: producer: role: roles/producer.yaml sink: type: delegate target: consumer consumer: role: roles/consumer.yaml depends_on: - producer ``` ```bash # Validate initrunner compose validate compose.yaml # Start (foreground, Ctrl+C to stop) initrunner compose up compose.yaml ``` ## Compose Definition The top-level structure follows the `apiVersion`/`kind`/`metadata`/`spec` pattern: | Field | Type | Default | Description | |-------|------|---------|-------------| | `apiVersion` | `str` | *(required)* | e.g. `initrunner/v1` | | `kind` | `str` | *(required)* | Must be `"Compose"` | | `metadata.name` | `str` | *(required)* | Compose definition name | | `metadata.description` | `str` | `""` | Human-readable description | | `spec.services` | `dict` | *(required)* | Map of service name to configuration | ## Service Configuration ```yaml services: my-service: role: roles/my-role.yaml sink: type: delegate target: other-service depends_on: - dependency-service restart: condition: on-failure max_retries: 3 delay_seconds: 5 environment: {} ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `role` | `str` | *(required)* | Path to role YAML (relative to compose file) | | `sink` | `object \| null` | `null` | Delegate sink for routing output | | `depends_on` | `list[str]` | `[]` | Services that must start first | | `restart.condition` | `str` | `"none"` | `"none"`, `"on-failure"`, or `"always"` | | `restart.max_retries` | `int` | `3` | Maximum restart attempts | | `restart.delay_seconds` | `int` | `5` | Seconds before restarting | | `environment` | `dict` | `{}` | Additional environment variables | ## Delegate Sinks Route a service's output to other services via in-memory queues. ```yaml # Single target sink: type: delegate target: consumer queue_size: 100 timeout_seconds: 60 # Fan-out to multiple targets sink: type: delegate target: - researcher - responder keep_existing_sinks: true ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `type` | `str` | *(required)* | Must be `"delegate"` | | `target` | `str \| list[str]` | *(required)* | Target service name(s) | | `keep_existing_sinks` | `bool` | `false` | Also activate role-level sinks | | `queue_size` | `int` | `100` | Max buffered events in target's inbox | | `timeout_seconds` | `int` | `60` | Block time when queue is full before dropping | Only successful runs are forwarded. Failed runs are silently skipped. ## Startup Order Services start in topological order based on `depends_on`. Services without dependencies start first, forming tiers of parallel startup. Shutdown happens in reverse order. ```yaml services: inbox-watcher: role: roles/inbox-watcher.yaml sink: { type: delegate, target: triager } triager: role: roles/triager.yaml depends_on: [inbox-watcher] sink: { type: delegate, target: [researcher, responder] } researcher: role: roles/researcher.yaml depends_on: [triager] responder: role: roles/responder.yaml depends_on: [triager] ``` ``` Tier 0: inbox-watcher (no dependencies) Tier 1: triager (depends on inbox-watcher) Tier 2: researcher, responder (both depend on triager) ``` ## Restart Policies | Condition | Restart when... | |-----------|----------------| | `none` | Never restart | | `on-failure` | Restart only if errors were recorded | | `always` | Restart whenever the service thread exits | A health monitor thread checks every 10 seconds and applies restart policies. ## Systemd Deployment Install compose pipelines as systemd user services for production: ```bash # Install the unit initrunner compose install compose.yaml # Start initrunner compose start my-pipeline # Enable on boot systemctl --user enable initrunner-my-pipeline.service # Monitor initrunner compose status my-pipeline initrunner compose logs my-pipeline -f ``` ### Environment Variables Systemd services don't inherit shell exports. Provide secrets via environment files: - `{compose_dir}/.env` — project-level secrets - `~/.initrunner/.env` — user-level defaults Use `--generate-env` to create a template `.env` file: ```bash initrunner compose install compose.yaml --generate-env ``` ### User Lingering To keep services running after logout: ```bash loginctl enable-linger $USER ``` ## Example: Email Pipeline ``` inbox-watcher ──> triager ──> researcher │ └──────> responder ``` ```yaml apiVersion: initrunner/v1 kind: Compose metadata: name: email-pipeline description: Multi-agent email processing pipeline spec: services: inbox-watcher: role: roles/inbox-watcher.yaml sink: type: delegate target: triager triager: role: roles/triager.yaml depends_on: [inbox-watcher] sink: type: delegate target: [researcher, responder] circuit_breaker_threshold: 5 researcher: role: roles/researcher.yaml depends_on: [triager] responder: role: roles/responder.yaml depends_on: [triager] restart: { condition: on-failure, max_retries: 3, delay_seconds: 5 } ``` ### Service Roles Each service points to a standalone role YAML. Here are the two key roles in this pipeline: **`roles/triager.yaml`** — routes emails to the right handler: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: triager description: Routes emails to the right handler spec: role: > You are an email triage agent. Analyze the email summary and determine if it needs research (technical questions, data requests) or a direct response (simple inquiries, acknowledgments). Output your decision and reasoning clearly. model: provider: openai name: gpt-4o-mini temperature: 0.1 guardrails: max_tokens_per_run: 2000 timeout_seconds: 30 ``` **`roles/responder.yaml`** — drafts email responses: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: responder description: Drafts email responses spec: role: > You are an email response agent. Given a triaged email that needs a direct response, draft a professional, helpful reply. Keep the tone friendly and concise. model: provider: openai name: gpt-4o-mini temperature: 0.5 guardrails: max_tokens_per_run: 3000 timeout_seconds: 30 ``` > Service roles are minimal — they focus on a single task and don't need triggers or sinks (the compose file handles routing). This keeps each agent simple and testable independently. ## Example: CI Pipeline A webhook-driven pipeline that processes CI events, diagnoses build failures, and sends notifications. ``` webhook-receiver ──> build-analyzer ──> notifier ``` ### `compose.yaml` ```yaml apiVersion: initrunner/v1 kind: Compose metadata: name: ci-pipeline description: CI event processing pipeline spec: services: webhook-receiver: role: roles/webhook-receiver.yaml sink: type: delegate target: build-analyzer build-analyzer: role: roles/build-analyzer.yaml depends_on: [webhook-receiver] sink: type: delegate target: notifier notifier: role: roles/notifier.yaml depends_on: [build-analyzer] restart: { condition: on-failure, max_retries: 3, delay_seconds: 5 } ``` ### `roles/notifier.yaml` The most interesting service — it combines Slack messaging with the GitHub commit status API: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: ci-notifier description: Sends Slack notifications and updates GitHub commit status spec: role: | You are a CI notification agent. You receive analyzed build events and: 1. Send a formatted Slack notification: - Success: "✅ Build passed — [repo] @ [branch] ([sha])" - Failure: "❌ Build failed — [repo] @ [branch] ([sha])\n Diagnosis: [diagnosis]\nCategory: [category]" - Include the build URL as a link - Add a timestamp via get_current_time 2. Update the GitHub commit status using the create_commit_status API endpoint: - state: "success" or "failure" - description: brief status message - context: "ci-pipeline/initrunner" Always send both the Slack message and the GitHub status update. model: provider: openai name: gpt-4o-mini temperature: 0.0 tools: - type: slack webhook_url: "${SLACK_WEBHOOK_URL}" default_channel: "#ci-alerts" username: CI Pipeline icon_emoji: ":construction_worker:" - type: api name: github-status description: GitHub commit status API base_url: https://api.github.com headers: Accept: application/vnd.github.v3+json auth: Authorization: "Bearer ${GITHUB_TOKEN}" endpoints: - name: create_commit_status method: POST path: "/repos/{owner}/{repo}/statuses/{sha}" description: Create a commit status check parameters: - name: owner type: string required: true - name: repo type: string required: true - name: sha type: string required: true - name: state type: string required: true description: "pending, success, failure, or error" - name: description type: string required: false - name: context type: string required: false default: "ci-pipeline/initrunner" body_template: state: "{state}" description: "{description}" context: "{context}" timeout: 15 - type: datetime guardrails: max_tokens_per_run: 15000 max_tool_calls: 10 timeout_seconds: 60 ``` ### Test the webhook ```bash # Start the pipeline initrunner compose up compose.yaml # In another terminal, send a test event curl -X POST http://localhost:9090/ci-webhook \ -H "Content-Type: application/json" \ -d '{ "source": "github-actions", "repo": "myorg/myapp", "branch": "main", "sha": "abc12345", "status": "failure", "author": "dev@example.com", "message": "fix: update auth middleware", "url": "https://github.com/myorg/myapp/actions/runs/12345" }' ``` > **What to notice:** The notifier combines two tool types — `slack` for human-readable alerts and `api` for machine-readable GitHub status updates. The webhook receiver uses a `webhook` trigger (port 9090), and the compose file wires all three services together with delegate sinks. ## Example: Content Pipeline ``` content-watcher ──> researcher ──> writer │ └──────> reviewer ``` Uses `process_existing: true` on the file watch trigger to handle files already in the directory on startup. See [Triggers](/docs/triggers) for details. > See also: [Team Mode](/docs/team-mode) for single-file multi-persona collaboration — simpler than Compose when you need multiple perspectives on the same task rather than independent services. ## Safety & Observability ### Guardrails # Guardrails Guardrails prevent runaway agents by enforcing per-run limits, session budgets, daemon budgets, and autonomous budgets. All limits are enforced automatically — agents stop when a limit is hit and warn at 80% consumption. ## Quick Example ```yaml guardrails: max_tokens_per_run: 50000 max_tool_calls: 20 timeout_seconds: 300 session_token_budget: 200000 # Team mode guardrails (kind: Team only) team_token_budget: 150000 # cumulative budget across all personas team_timeout_seconds: 900 # wall-clock limit for entire team run ``` ## Per-Run Limits These limits apply to each individual agent run (a single invocation or trigger execution). | Field | Type | Default | Description | |-------|------|---------|-------------| | `max_tokens_per_run` | `int` | `50000` | Maximum output tokens consumed per agent run | | `max_tool_calls` | `int` | `20` | Maximum tool invocations per run | | `timeout_seconds` | `int` | `300` | Wall-clock timeout per run (seconds) | | `max_request_limit` | `int \| null` | auto | Maximum LLM API round-trips per run. Auto-derived as `max(max_tool_calls + 10, 30)` when not set | | `input_tokens_limit` | `int \| null` | `null` | Per-request input token limit | | `total_tokens_limit` | `int \| null` | `null` | Per-request combined input+output token limit | ## Session Budgets ```yaml guardrails: session_token_budget: 500000 ``` `session_token_budget` tracks cumulative token usage across interactive REPL turns (`-i` mode). The agent warns at 80% consumption and stops accepting new prompts at 100%. This is useful for long-running interactive sessions where you want to cap total spend. ## Daemon Budgets Daemon-mode agents (`initrunner daemon`) can have lifetime and daily budgets: | Field | Type | Default | Description | |-------|------|---------|-------------| | `daemon_token_budget` | `int \| null` | `null` | Lifetime token budget for the daemon process | | `daemon_daily_token_budget` | `int \| null` | `null` | Daily token budget — resets at UTC midnight | ```yaml guardrails: daemon_token_budget: 1000000 daemon_daily_token_budget: 100000 ``` When a daemon budget is exhausted, triggers are skipped until the budget resets (daily) or the daemon is restarted (lifetime). ## Autonomous Limits These fields control resource usage for [autonomous mode](/docs/autonomy) runs: | Field | Type | Default | Description | |-------|------|---------|-------------| | `max_iterations` | `int` | `10` | Maximum plan-execute-adapt cycles | | `autonomous_token_budget` | `int \| null` | `null` | Token budget for the autonomous run | | `autonomous_timeout_seconds` | `int \| null` | `null` | Wall-clock timeout for the entire autonomous run | ```yaml guardrails: max_iterations: 10 autonomous_token_budget: 50000 autonomous_timeout_seconds: 600 ``` When any autonomous limit is hit, the agent stops and reports its progress via `finish_task`. ## Team Budgets These fields control resource usage for [team mode](/docs/team-mode) runs (`kind: Team`): | Field | Type | Default | Description | |-------|------|---------|-------------| | `team_token_budget` | `int` | `null` | Cumulative token budget across all personas in a team run. Pipeline stops if exceeded. Team mode only. | | `team_timeout_seconds` | `int` | `null` | Wall-clock limit for entire team run. Pipeline stops if exceeded. Team mode only. | ```yaml guardrails: team_token_budget: 150000 team_timeout_seconds: 900 ``` Team budgets protect team runs from unbounded spend across personas. Per-run limits (`max_tokens_per_run`, `timeout_seconds`) still apply to each individual persona. See [Team Mode](/docs/team-mode). ## Enforcement Behavior Each limit type has specific enforcement behavior: | Limit | What Happens | |-------|-------------| | `max_tokens_per_run` | PydanticAI raises `UsageLimitExceeded` — the run stops immediately | | `max_tool_calls` | PydanticAI raises `UsageLimitExceeded` — the run stops immediately | | `timeout_seconds` | Python raises `TimeoutError` — the run is cancelled | | `max_request_limit` | PydanticAI raises `UsageLimitExceeded` — no more API round-trips | | `input_tokens_limit` | PydanticAI raises `UsageLimitExceeded` on the next request | | `total_tokens_limit` | PydanticAI raises `UsageLimitExceeded` on the next request | | `session_token_budget` | Warns at 80%, stops accepting prompts at 100% | | `daemon_token_budget` | Triggers are skipped when exhausted | | `daemon_daily_token_budget` | Triggers are skipped until UTC midnight reset | | `max_iterations` | Autonomous loop terminates, agent reports progress | | `autonomous_token_budget` | Autonomous loop terminates, agent reports progress | | `autonomous_timeout_seconds` | Autonomous loop terminates, agent reports progress | | `team_token_budget` | Team pipeline stops, partial results returned | | `team_timeout_seconds` | Team pipeline stops, partial results returned | The **80% warning** applies to `session_token_budget`, `daemon_token_budget`, and `daemon_daily_token_budget`. When 80% of the budget is consumed, a warning is logged so operators can take action before the hard stop. ## Visibility Guardrail status is surfaced across multiple interfaces: | Surface | What's Shown | |---------|-------------| | `initrunner validate` | Warns if guardrails are missing or misconfigured | | REPL subtitle | Live token usage and remaining budget | | TUI status bar | Per-run and session budget consumption bars | | Dashboard API | `/api/agents/:id/usage` endpoint returns current budget state | | Audit logs | Every limit hit is recorded with the limit name and value | ## Tool Output Limits Individual tool outputs are capped to prevent a single response from consuming the entire context window: | Tool | Max Output Size | Behavior When Exceeded | |------|----------------|----------------------| | `read_file` | 1 MB | Output is truncated with a `[truncated]` marker | | `http_request` | 100 KB | Response body is truncated; headers are preserved | | `shell` | 100 KB | stdout/stderr combined output is truncated | | `search_documents` | 50 KB | Results are truncated; match count is still reported | These limits are not configurable — they are hard-coded safety rails to protect context window budget. If you need larger outputs, read files in chunks or paginate HTTP responses. ## Example Configurations ### Cost-Conscious Development Tight limits for iterative development where you want fast feedback and low spend: ```yaml guardrails: max_tokens_per_run: 10000 max_tool_calls: 10 timeout_seconds: 60 session_token_budget: 50000 ``` ### Production Daemon A daemon role with daily budgets and autonomous limits: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: monitor-agent description: Monitors infrastructure and auto-remediates issues spec: role: | You are an infrastructure monitor. Check system health when triggered, diagnose issues, and apply standard remediations. model: provider: openai name: gpt-4o-mini temperature: 0.0 tools: - type: shell allowed_commands: [curl, systemctl, journalctl] require_confirmation: false timeout_seconds: 30 triggers: - type: cron schedule: "*/5 * * * *" prompt: "Run a health check on all services." autonomous: true autonomy: max_plan_steps: 8 max_history_messages: 20 iteration_delay_seconds: 2 guardrails: # Per-run limits max_tokens_per_run: 15000 max_tool_calls: 10 timeout_seconds: 120 # Daemon budgets daemon_token_budget: 5000000 daemon_daily_token_budget: 500000 # Autonomous limits max_iterations: 5 autonomous_token_budget: 30000 autonomous_timeout_seconds: 300 ``` ### RAG with Budget A knowledge-base agent with session budgets to cap interactive usage: ```yaml guardrails: max_tokens_per_run: 30000 max_tool_calls: 15 timeout_seconds: 180 session_token_budget: 200000 input_tokens_limit: 16000 ``` ## CLI Overrides ```bash # Override max iterations for autonomous mode initrunner run role.yaml -a --max-iterations 5 ``` The `--max-iterations N` flag overrides the `max_iterations` value from the YAML file for that run. ### Security # Security InitRunner includes a `SecurityPolicy` configuration that enforces content policies, rate limiting, tool sandboxing, and audit compliance. All security features are optional — existing roles without a `security:` key get safe defaults with all checks disabled. ## Quick Start ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: my-agent spec: role: You are a helpful assistant. model: provider: openai name: gpt-4o-mini security: content: blocked_input_patterns: - "ignore previous instructions" pii_redaction: true rate_limit: requests_per_minute: 30 burst_size: 5 ``` ## Content Policy Controls input validation, output filtering, and audit redaction. | Field | Type | Default | Description | |-------|------|---------|-------------| | `profanity_filter` | `bool` | `false` | Block profane input (requires `initrunner[safety]`) | | `blocked_input_patterns` | `list[str]` | `[]` | Regex patterns that reject matching prompts | | `blocked_output_patterns` | `list[str]` | `[]` | Regex patterns applied to agent output | | `output_action` | `str` | `"strip"` | `"strip"` replaces matches with `[FILTERED]`; `"block"` rejects entire output | | `llm_classifier_enabled` | `bool` | `false` | Use the agent's model to classify input against a topic policy | | `allowed_topics_prompt` | `str` | `""` | Natural-language policy for the LLM classifier | | `max_prompt_length` | `int` | `50000` | Maximum prompt length in characters | | `max_output_length` | `int` | `100000` | Maximum output length (truncated) | | `redact_patterns` | `list[str]` | `[]` | Regex patterns to redact in audit logs | | `pii_redaction` | `bool` | `false` | Redact built-in PII patterns (email, SSN, phone, API keys) in audit logs | ### Input Validation Pipeline Validation runs in order, stopping on the first failure: 1. **Profanity filter** — `better-profanity` library check 2. **Blocked patterns** — regex matching 3. **Prompt length** — character count check 4. **LLM classifier** — model-based topic classification (opt-in) ### LLM Classifier ```yaml security: content: llm_classifier_enabled: true allowed_topics_prompt: | ALLOWED: Product questions, order status, returns, shipping BLOCKED: Competitor comparisons, off-topic, requests to ignore instructions ``` ## Rate Limiting Token-bucket rate limiter applied to all `/v1/` endpoints. | Field | Type | Default | Description | |-------|------|---------|-------------| | `requests_per_minute` | `int` | `60` | Sustained request rate | | `burst_size` | `int` | `10` | Maximum burst capacity | Returns HTTP 429 when exceeded. ## Tool Sandboxing Controls custom tool loading, MCP subprocess security, and store path restrictions. | Field | Type | Default | Description | |-------|------|---------|-------------| | `allowed_custom_modules` | `list[str]` | `[]` | Module allowlist (overrides blocklist if non-empty) | | `blocked_custom_modules` | `list[str]` | *(defaults)* | Modules blocked from custom tool imports | | `mcp_command_allowlist` | `list[str]` | `[]` | Allowed MCP stdio commands (empty = all) | | `sensitive_env_prefixes` | `list[str]` | *(defaults)* | Env var prefixes scrubbed from subprocesses | | `restrict_db_paths` | `bool` | `true` | Require store databases under `~/.initrunner/` | | `audit_hooks_enabled` | `bool` | `false` | Enable PEP 578 audit hook sandbox | | `allowed_write_paths` | `list[str]` | `[]` | Paths custom tools can write to (empty = all blocked) | | `allowed_network_hosts` | `list[str]` | `[]` | Hostnames custom tools can resolve (empty = all) | | `block_private_ips` | `bool` | `true` | Block connections to RFC 1918/loopback/link-local | | `allow_subprocess` | `bool` | `false` | Allow custom tools to spawn subprocesses | | `allow_eval_exec` | `bool` | `false` | Allow `eval()`/`exec()`/`compile()` | ### AST-Based Import Analysis Custom tools are statically analyzed using Python's `ast` module before loading. Blocked imports raise a `ValueError` and prevent agent loading. ### PEP 578 Audit Hooks When `audit_hooks_enabled: true`, a PEP 578 audit hook fires at the C-interpreter level on `open()`, `socket.connect()`, `subprocess.Popen()`, `import`, `exec`, and `compile` — regardless of how the call was made. ```yaml security: tools: audit_hooks_enabled: true allowed_write_paths: [/tmp/agent-workspace] allowed_network_hosts: [api.example.com] block_private_ips: true allow_subprocess: false sandbox_violation_action: raise ``` Set `sandbox_violation_action: log` to discover violations before enforcing. ## Tool Permissions Tool permissions provide a second defense layer that controls **argument-level access** per tool call. While tool sandboxing controls process-level access (modules, subprocesses, network), tool permissions let you declare allow/deny rules on the values passed to individual tool calls. ```yaml tools: - type: shell allowed_commands: [kubectl, docker] permissions: default: deny allow: - command=kubectl get * - command=docker ps * ``` | Layer | Controls | Config Location | |-------|----------|-----------------| | Tool sandboxing | Module imports, subprocesses, network, write paths | `spec.security.tools` | | Tool permissions | Argument values per tool call | `spec.tools[*].permissions` | See [Tool Permissions](/docs/tools#tool-permissions) for the full field table, pattern syntax, and examples. ## Docker Sandbox Runs shell, Python, and script tool execution inside Docker containers for kernel-level isolation (network namespaces, cgroups, read-only filesystem). Docker sandbox is opt-in via `enabled: true`. | Field | Type | Default | Description | |-------|------|---------|-------------| | `enabled` | `bool` | `false` | Enable Docker container isolation for tool execution. | | `image` | `str` | `"python:3.12-slim"` | Docker image to use. | | `network` | `"none" \| "bridge" \| "host"` | `"none"` | Container network mode. | | `memory_limit` | `str` | `"256m"` | Memory limit in Docker format. | | `cpu_limit` | `float` | `1.0` | CPU limit (fractional cores). | | `read_only_rootfs` | `bool` | `true` | Read-only root filesystem. | | `bind_mounts` | `list[BindMount]` | `[]` | Additional bind mounts. | | `env_passthrough` | `list[str]` | `[]` | Env vars to pass through. | | `extra_args` | `list[str]` | `[]` | Extra `docker run` flags (dangerous flags blocked). | See [Docker Sandbox](/docs/docker-sandbox) for full configuration, security defaults, and examples. ## Server Configuration Controls the OpenAI-compatible API server (`initrunner serve`). | Field | Type | Default | Description | |-------|------|---------|-------------| | `cors_origins` | `list[str]` | `[]` | Allowed CORS origins (empty = no CORS headers) | | `require_https` | `bool` | `false` | Reject requests without `X-Forwarded-Proto: https` | | `max_request_body_bytes` | `int` | `1048576` | Maximum request body size (1 MB) | | `max_conversations` | `int` | `1000` | Maximum concurrent conversations | ## Audit Configuration | Field | Type | Default | Description | |-------|------|---------|-------------| | `max_records` | `int` | `100000` | Maximum audit log records | | `retention_days` | `int` | `90` | Delete records older than this | Prune old records: ```bash initrunner audit prune initrunner audit prune --retention-days 30 --max-records 50000 ``` ## Example: Customer-Facing (Strict) ```yaml security: content: profanity_filter: true llm_classifier_enabled: true allowed_topics_prompt: | ALLOWED: Product questions, order status, returns, shipping BLOCKED: Competitor comparisons, off-topic, requests to ignore instructions blocked_input_patterns: - "ignore previous instructions" - "system:\\s*" blocked_output_patterns: - "\\b(password|secret)\\s*[:=]\\s*\\S+" output_action: block max_prompt_length: 10000 pii_redaction: true server: cors_origins: ["https://myapp.example.com"] require_https: true rate_limit: requests_per_minute: 30 burst_size: 5 tools: mcp_command_allowlist: ["npx", "uvx"] audit_hooks_enabled: true allowed_write_paths: [] block_private_ips: true audit: retention_days: 30 max_records: 50000 ``` ## Example: Internal Tool (Minimal) ```yaml security: content: profanity_filter: true blocked_input_patterns: - "drop table" output_action: strip ``` ## Bot Token Redaction Telegram and Discord bot tokens are automatically redacted in audit logs. Additionally, `TELEGRAM_BOT_TOKEN` and `DISCORD_BOT_TOKEN` are scrubbed from subprocess environments to prevent accidental leakage to child processes. This applies to both daemon mode (`initrunner daemon`) and one-command bot mode (`initrunner chat --telegram` / `--discord`). No configuration is needed — redaction is always active when messaging triggers are in use. ## Example: Development Omit the `security:` key entirely — all checks are disabled by default. ### Docker Sandbox # Docker Sandbox InitRunner can run shell, Python, and script tool execution inside Docker containers, providing kernel-level isolation via network namespaces, cgroups, and filesystem restrictions. This is **opt-in** via `security.docker.enabled: true` in your role YAML. When disabled (the default), no behavior changes. ## Quick Start ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: sandboxed-agent spec: role: You are a code execution assistant. model: provider: openai name: gpt-5-mini tools: - type: shell - type: python security: docker: enabled: true ``` This runs all shell and Python tool invocations inside `python:3.12-slim` containers with no network access and a read-only root filesystem. ## Prerequisites Docker must be installed and the daemon running. Verify with: ```bash initrunner doctor ``` The [doctor](/docs/doctor) command shows a `docker` row in the provider status table. If Docker is enabled in a role but not available, the agent fails to load with a `DockerNotAvailableError`. ## Configuration Reference All fields under `security.docker`: | Field | Type | Default | Description | |-------|------|---------|-------------| | `enabled` | `bool` | `false` | Enable Docker container isolation for tool execution. | | `image` | `str` | `"python:3.12-slim"` | Docker image to use for containers. | | `network` | `"none" \| "bridge" \| "host"` | `"none"` | Container network mode. `none` provides full network isolation. | | `memory_limit` | `str` | `"256m"` | Memory limit in Docker format (`256m`, `1g`, etc.). | | `cpu_limit` | `float` | `1.0` | CPU limit (fractional cores, must be > 0). | | `read_only_rootfs` | `bool` | `true` | Mount root filesystem as read-only. A writable `/tmp` (64MB, noexec) is added automatically. | | `bind_mounts` | `list[BindMount]` | `[]` | Additional bind mounts into the container. | | `env_passthrough` | `list[str]` | `[]` | Environment variable names to pass into the container (filtered through env scrubbing). | | `extra_args` | `list[str]` | `[]` | Additional `docker run` flags. Security-sensitive flags are blocked. | ### BindMount Fields | Field | Type | Default | Description | |-------|------|---------|-------------| | `source` | `str` | *(required)* | Host path. Relative paths resolve against the role file's directory. | | `target` | `str` | *(required)* | Container path. Must be absolute (start with `/`). | | `read_only` | `bool` | `true` | Mount as read-only. | ## Security Defaults The Docker sandbox applies strong defaults: - **`network: none`** — Containers have no network access by default. This is enforced at the kernel level and cannot be bypassed from inside the container. - **`read_only_rootfs: true`** — The container's root filesystem is read-only. A writable `/tmp` is provided with `noexec,nosuid` flags and a 64MB size limit. - **`pids-limit: 256`** — Limits the number of processes inside the container to prevent fork bombs. - **Working directory** — The tool's working directory is bind-mounted at `/work` inside the container. The `/work` target is reserved and cannot be used in `bind_mounts`. ## Network Isolation The `network` field controls container networking: | Value | Behavior | |-------|----------| | `none` | No network access (strongest isolation). | | `bridge` | Container gets its own network namespace with NAT. Can access external hosts. | | `host` | Container shares the host's network namespace. Least isolated. | ### Interaction with `network_disabled` The Python tool has an existing `network_disabled` option that installs an in-process audit hook to block socket connections. When Docker is enabled: - **`network: none`** — Docker provides kernel-level network isolation. The in-process shim is skipped (redundant). - **`network: bridge` or `host`** — If `network_disabled: true`, the in-process shim is preserved inside the container for defense-in-depth. ## Blocked Extra Args The following `docker run` flags are blocked in `extra_args` to prevent privilege escalation: - `--privileged` - `--cap-add` - `--security-opt` - `--pid=host` - `--userns=host` - `--network=host` - `--ipc=host` Attempting to use these raises a validation error at role load time. ## Examples ### Data Processing with File Access ```yaml security: docker: enabled: true image: python:3.12-slim network: none memory_limit: 512m cpu_limit: 2.0 bind_mounts: - source: ./data target: /data read_only: true - source: ./output target: /output read_only: false env_passthrough: [LANG, TZ] ``` ### Minimal Sandbox ```yaml security: docker: enabled: true ``` Uses all defaults: `python:3.12-slim`, no network, 256MB RAM, 1 CPU, read-only rootfs. ### Custom Image with Extra Args ```yaml security: docker: enabled: true image: node:20-slim memory_limit: 1g read_only_rootfs: false extra_args: ["--pids-limit=100", "--ulimit=nofile=1024"] ``` ### Complete Example Role See the [`docker-sandbox` example](/docs/examples#role-examples) for a ready-to-use role with Docker isolation: ```bash initrunner examples copy docker-sandbox initrunner run docker-sandbox.yaml -p "Use python to compute 2**100" ``` ## How It Works When `security.docker.enabled` is `true`: 1. **Startup validation** — `build_toolsets()` calls `require_docker()` to verify the Docker CLI and daemon are available. If not, the agent fails to load. 2. **Shell tools** — Instead of `subprocess.run(tokens, ...)`, the tool runs `docker run --rm `. The working directory is bind-mounted at `/work`. 3. **Python tools** — Code is written to a temporary file, bind-mounted at `/code/_run.py`, and executed via `docker run --rm python /code/_run.py`. The temp directory is always cleaned up. 4. **Script tools** — The script body is piped via stdin to `docker run -i --rm `. Script environment variables are passed as `-e` flags. All three paths reuse the existing timeout handling, output formatting, and truncation logic. `SubprocessTimeout` is raised on timeout just as in the non-Docker path. ## Limitations - **Docker overhead** — Container startup adds latency (~100-500ms per invocation depending on image and system). Not suitable for high-frequency tool calls. - **Image availability** — The specified image must be pulled or available locally. Docker will pull it on first use, which can be slow. - **No GPU passthrough** — The sandbox does not configure `--gpus`. Add `--gpus=all` via `extra_args` if needed (note: this reduces isolation). - **Host paths** — Bind mount source paths must exist on the host. Relative paths resolve against the role file's directory. ### Audit Trail # Audit Trail InitRunner automatically logs every agent run to a local SQLite database. Audit records capture what happened, how much it cost, and whether it succeeded — giving you a complete history of agent behavior. For distributed tracing and deeper performance analysis, see [Observability](/docs/observability). ## What Gets Logged Every agent run produces an audit record with these fields: | Field | Type | Description | |-------|------|-------------| | `run_id` | `str` | Unique run identifier (12-character hex) | | `agent_name` | `str` | Name from `metadata.name` | | `timestamp` | `datetime` | UTC timestamp of run start | | `prompt` | `str` | Input prompt (subject to redaction) | | `output` | `str` | Agent output (subject to redaction) | | `tokens_in` | `int` | Input tokens consumed | | `tokens_out` | `int` | Output tokens consumed | | `tool_calls` | `list` | Tool invocations with name, args, and result | | `duration_ms` | `int` | Wall-clock duration in milliseconds | | `success` | `bool` | Whether the run completed without error | | `error` | `str \| null` | Error message if the run failed | | `trigger_type` | `str` | How the run was initiated: `prompt`, `cron`, `file_watch`, `webhook`, `autonomous` | ## Storage Audit records are stored in a SQLite database: - **Default path:** `~/.initrunner/audit.db` - **Custom path:** `--audit-db ./custom-audit.db` - **Disable entirely:** `--no-audit` ```bash # Default audit database initrunner run role.yaml -p "Hello" # Custom audit database path initrunner run role.yaml -p "Hello" --audit-db ./my-audit.db # Disable audit logging initrunner run role.yaml -p "Hello" --no-audit ``` The same flags work with `initrunner daemon` and `initrunner serve`. ## Export Export audit records as JSON or CSV for analysis, reporting, or ingestion into external systems. ```bash initrunner audit export ``` | Flag | Type | Default | Description | |------|------|---------|-------------| | `--agent` | `str` | *(all)* | Filter by agent name | | `--trigger-type` | `str` | *(all)* | Filter by trigger type (`prompt`, `cron`, `file_watch`, `webhook`, `autonomous`) | | `--since` | `str` | *(none)* | Start date (ISO 8601, e.g. `2025-01-01`) | | `--until` | `str` | *(none)* | End date (ISO 8601) | | `--limit` | `int` | `1000` | Maximum records to export | | `-f, --format` | `str` | `"json"` | Output format: `json` or `csv` | | `-o, --output` | `str` | stdout | Output file path | ### Examples ```bash # Export all records as JSON initrunner audit export # Export last 7 days for a specific agent as CSV initrunner audit export --agent monitor-agent --since 2025-01-08 -f csv -o report.csv # Export only cron-triggered runs initrunner audit export --trigger-type cron --limit 500 # Export to a file initrunner audit export -o audit-export.json ``` ## Pruning Remove old audit records to manage database size. ### Manual Pruning ```bash initrunner audit prune initrunner audit prune --retention-days 30 --max-records 50000 ``` | Flag | Type | Default | Description | |------|------|---------|-------------| | `--retention-days` | `int` | `90` | Delete records older than this | | `--max-records` | `int` | `100000` | Keep at most this many records (oldest removed first) | ### Automatic Pruning Configure auto-pruning via the security policy in your role YAML: ```yaml security: audit: retention_days: 30 max_records: 50000 ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `retention_days` | `int` | `90` | Delete records older than this many days | | `max_records` | `int` | `100000` | Maximum audit records to retain | Auto-pruning runs at daemon startup and periodically during long-running daemons. ## Redaction Audit logs can contain sensitive information. InitRunner supports two redaction mechanisms to sanitize records before they are written. ### PII Redaction Enable built-in PII pattern detection: ```yaml security: content: pii_redaction: true ``` This redacts common PII patterns in both prompts and outputs before writing to the audit database: | Pattern | Example | Redacted As | |---------|---------|-------------| | Email addresses | `user@example.com` | `[EMAIL]` | | Social Security Numbers | `123-45-6789` | `[SSN]` | | Phone numbers | `+1-555-123-4567` | `[PHONE]` | | API keys | `sk-abc123...` | `[API_KEY]` | ### Custom Redaction Patterns Add regex patterns to redact domain-specific sensitive data: ```yaml security: content: redact_patterns: - "\\b[A-Z]{2}\\d{6}\\b" # internal account IDs - "\\btoken_[a-zA-Z0-9]+\\b" # internal tokens ``` Custom patterns are applied in addition to PII redaction (if enabled). Matches are replaced with `[REDACTED]`. ## Viewing Audit Logs Beyond the CLI export command, audit logs are accessible through: - **TUI** — the Audit panel provides a scrollable, filterable log viewer - **Web Dashboard** — the Audit Viewer offers search, pagination, and CSV/JSON export - **Direct SQLite access** — query `~/.initrunner/audit.db` with any SQLite client ```bash # Quick peek at recent records sqlite3 ~/.initrunner/audit.db "SELECT agent_name, trigger_type, success, duration_ms FROM audit ORDER BY timestamp DESC LIMIT 10" ``` ### Observability # Observability InitRunner supports opt-in distributed tracing via [OpenTelemetry](https://opentelemetry.io/). When enabled, agent runs, LLM requests, tool calls, ingestion pipelines, and delegation chains all emit traces that can be visualized in any OTel-compatible backend (Jaeger, Grafana Tempo, Datadog, Honeycomb, Logfire, etc.). The SQLite [audit trail](/docs/audit) remains the lightweight default. Observability adds a second, richer signal layer — both run side-by-side. ## Quick Start See traces in under a minute — no Docker, no external services: ```bash pip install initrunner[observability] initrunner run traced-agent.yaml -p "What time is it?" --no-audit ``` JSON spans print to stderr showing the full trace hierarchy: the parent `initrunner.agent.run` span, the PydanticAI `agent run` and `chat` spans, and the `running tool (get_current_time)` tool span. ### Console Output Example With `backend: console`, each completed span is printed to stderr as a JSON object. A typical run produces output like this (timestamps and IDs shortened for readability): ```json { "name": "running tool (get_current_time)", "context": { "trace_id": "0x3a1f...", "span_id": "0x8b2c...", "trace_state": "[]" }, "kind": "SpanKind.INTERNAL", "parent_id": "0x4d1e...", "start_time": "2026-02-17T12:00:00.100000Z", "end_time": "2026-02-17T12:00:00.102000Z", "status": { "status_code": "OK" }, "attributes": {} } ``` ```json { "name": "chat gpt-4o-mini", "context": { "trace_id": "0x3a1f...", "span_id": "0x4d1e..." }, "kind": "SpanKind.CLIENT", "parent_id": "0x9f3a...", "attributes": { "gen_ai.operation.name": "chat", "gen_ai.request.model": "gpt-4o-mini", "gen_ai.response.model": "gpt-4o-mini-2024-07-18", "gen_ai.usage.input_tokens": 85, "gen_ai.usage.output_tokens": 24 } } ``` ```json { "name": "initrunner.agent.run", "context": { "trace_id": "0x3a1f...", "span_id": "0x7e5b..." }, "kind": "SpanKind.INTERNAL", "attributes": { "initrunner.agent_name": "traced-agent", "initrunner.run_id": "a1b2c3d4", "initrunner.tokens_total": 109, "initrunner.duration_ms": 1200, "initrunner.success": true } } ``` Spans appear in completion order (leaf spans first, root span last). All spans share the same `trace_id`, forming a single trace. ## Installation ```bash pip install initrunner[observability] ``` This installs `opentelemetry-sdk`, `opentelemetry-exporter-otlp`, and `opentelemetry-instrumentation-logging`. For the Logfire backend, install separately: ```bash pip install logfire ``` ## Configuration Add an `observability` section to your role's `spec`: ```yaml spec: observability: backend: otlp # "otlp" | "logfire" | "console" endpoint: http://localhost:4317 service_name: my-agent # default: agent metadata.name trace_tool_calls: true trace_token_usage: true sample_rate: 1.0 include_content: false # include prompts/completions in spans ``` | Field | Type | Default | Description | |-------|------|---------|-------------| | `backend` | `otlp` \| `logfire` \| `console` | `otlp` | Exporter backend | | `endpoint` | string | `http://localhost:4317` | OTLP gRPC endpoint (ignored for console/logfire) | | `service_name` | string | agent name | Service name in traces | | `trace_tool_calls` | bool | `true` | Emit spans for tool calls | | `trace_token_usage` | bool | `true` | Emit token usage metrics | | `sample_rate` | float (0.0–1.0) | `1.0` | Trace sampling rate | | `include_content` | bool | `false` | Include prompt/completion text in spans | ## Quickstart with Jaeger ### Docker run ```bash docker run -d --name jaeger \ -p 16686:16686 \ -p 4317:4317 \ jaegertracing/all-in-one:latest ``` ### Docker Compose ```yaml # docker-compose.yaml services: jaeger: image: jaegertracing/all-in-one:latest ports: - "16686:16686" # Jaeger UI - "4317:4317" # OTLP gRPC ``` ```bash docker compose up -d ``` ### Run with OTLP Add observability to your role: ```yaml spec: observability: backend: otlp endpoint: http://localhost:4317 ``` Run your agent: ```bash initrunner run role.yaml -p "Hello, world" ``` Open Jaeger UI at `http://localhost:16686` and search for your agent's service name. ## Span Hierarchy When observability is enabled, traces follow this hierarchy: ``` initrunner.agent.run ← InitRunner parent span ├── agent run ← PydanticAI agent span │ ├── chat gpt-4o ← LLM request span │ ├── running tool (my_tool) ← Tool execution span │ └── chat gpt-4o ← Follow-up LLM request └── initrunner.ingest ← Ingestion pipeline span (if applicable) ``` ### InitRunner-Specific Spans | Span Name | Attributes | |-----------|------------| | `initrunner.agent.run` | `initrunner.run_id`, `initrunner.agent_name`, `initrunner.trigger_type`, `initrunner.tokens_total`, `initrunner.duration_ms`, `initrunner.success` | | `initrunner.ingest` | `initrunner.agent_name`, `initrunner.ingest.files_processed`, `initrunner.ingest.chunks_created` | ### PydanticAI Spans (Automatic) PydanticAI emits these spans when `instrument` is set on the Agent: - **`agent run`** — Full agent run lifecycle - **`chat {model}`** — Each LLM API call (`SpanKind.CLIENT`) - **`running tool`** — Each tool execution - **`gen_ai.client.token.usage`** — Token usage histogram metric ## Distributed Traces via Delegation In compose orchestrations, trace context propagates automatically through delegation chains using W3C Trace Context (`traceparent`/`tracestate` headers). ``` initrunner.agent.run [service_a] ├── agent run [PydanticAI] │ ├── chat gpt-4o │ └── running tool (delegate) └── initrunner.agent.run [service_b] ← linked via traceparent └── agent run [PydanticAI] └── chat gpt-4o ``` This means you can visualize an entire multi-agent pipeline as a single distributed trace in Jaeger or your preferred backend. ## Backends ### OTLP (Default) Sends traces via gRPC to any OTLP-compatible collector. Uses `BatchSpanProcessor` for efficient batching. ### Console Prints spans to stderr. Useful for quick debugging: ```yaml spec: observability: backend: console ``` ### Logfire Uses [Pydantic Logfire](https://logfire.pydantic.dev/) for managed observability: ```yaml spec: observability: backend: logfire service_name: my-agent ``` Logfire manages its own `TracerProvider` — InitRunner delegates to `logfire.configure()` and does not create a manual provider. ## Audit vs Observability Both systems record agent activity, but they serve different purposes: | | Audit Trail | Observability | |---|---|---| | **Purpose** | Compliance, history, debugging | Distributed tracing, performance analysis | | **Backend** | Local SQLite (built-in) | Any OTel collector (Jaeger, Tempo, Datadog, etc.) | | **Dependencies** | None (included) | `pip install initrunner[observability]` | | **Default** | Enabled | Opt-in | | **Granularity** | One record per agent run | Nested spans (run → LLM call → tool call) | | **Multi-agent** | Independent per-run records | Distributed traces across delegation chains | | **Query** | SQL / `initrunner audit export` | Jaeger UI, Grafana, vendor dashboards | | **Retention** | Auto-pruned SQLite (configurable) | Managed by your OTel backend | **Use audit** when you need a lightweight, zero-dependency log of what happened — prompts, outputs, token usage, and success/failure for every run. **Use observability** when you need to understand *how* it happened — latency breakdowns across LLM calls and tools, distributed traces across multi-agent pipelines, and integration with your existing monitoring stack. Both can run simultaneously. See [Audit Trail](/docs/audit) for audit configuration. ## Log Correlation When observability is enabled, Python log records are automatically enriched with `trace_id` and `span_id` fields via OTel's `LoggingInstrumentor`. This allows correlating application logs with traces in backends that support log-trace correlation (Grafana Loki + Tempo, Datadog, etc.). ## Zero Overhead When Disabled When `spec.observability` is not set: - No OTel SDK is imported - `trace.get_tracer("initrunner")` returns a no-op tracer - Span context injection/extraction are no-ops - CLI startup time is unaffected ## Troubleshooting ### Missing SDK ``` RuntimeError: OpenTelemetry observability requires: pip install initrunner[observability] ``` Install the optional dependency group: `pip install initrunner[observability]` ### No Traces Appearing 1. Verify the OTLP endpoint is reachable: `curl http://localhost:4317` 2. Check `sample_rate` is not `0.0` 3. Try `backend: console` to verify spans are being created 4. Ensure the collector/Jaeger is accepting gRPC on port 4317 (not HTTP on 4318) ### Duplicate Spans with Logfire If you see duplicate spans when using `backend: logfire`, ensure you're not also setting up a manual `TracerProvider` elsewhere. Logfire manages its own providers — InitRunner correctly delegates to `logfire.configure()` without creating additional providers. ### Testing # Testing InitRunner includes built-in tools for testing agents before deploying them — schema validation, dry-run mode (no API calls), and an eval-style test suite runner. ## Validation Validate a role YAML against the schema without running the agent: ```bash initrunner validate role.yaml ``` This checks: - YAML syntax and structure - Required fields (`apiVersion`, `kind`, `metadata.name`, `spec.role`) - Field types and value ranges (e.g. `temperature` between 0.0 and 2.0) - Tool configurations (valid types, required fields per type) - Skill references (file exists, frontmatter is valid) - Trigger configurations (valid cron expressions, valid paths) - Security policy structure Validation exits with code 0 on success and non-zero on failure, making it suitable for CI pipelines. ## Dry-Run Mode Run an agent without making any LLM API calls: ```bash initrunner run role.yaml --dry-run -p "Test prompt" ``` Dry-run mode replaces the configured model with a `TestModel` that returns deterministic placeholder responses. This lets you verify: - Tool registration and discovery - Trigger configuration and startup - Memory system initialization - Skill loading and merging - Guardrail enforcement logic - Sink configuration No API keys are required and no tokens are consumed. Use dry-run mode during development to catch configuration errors before spending on API calls. ## Test Suites The `initrunner test` command runs structured test suites against an agent using an eval framework. ```bash initrunner test role.yaml -s test_suite.yaml ``` ### Test Suite Format A test suite is a YAML file defining test cases with inputs and expected outcomes: ```yaml name: support-agent-tests description: Regression tests for the support agent tests: - name: answers_product_question prompt: "What is the return policy?" assertions: - type: contains value: "30 days" - type: contains value: "refund" - name: rejects_off_topic prompt: "What's the weather like?" assertions: - type: not_contains value: "forecast" - type: max_tokens value: 200 - name: uses_search_tool prompt: "Find articles about shipping delays" assertions: - type: tool_called value: search_documents - type: contains value: "shipping" - name: stays_within_budget prompt: "Write a comprehensive guide to our product line" assertions: - type: max_tokens value: 4096 - type: max_tool_calls value: 10 ``` ### Assertion Types | Type | Description | |------|-------------| | `contains` | Output contains the specified string (case-insensitive) | | `not_contains` | Output does not contain the specified string | | `regex` | Output matches the regex pattern | | `max_tokens` | Output token count is within the limit | | `max_tool_calls` | Number of tool calls is within the limit | | `tool_called` | The specified tool was invoked during the run | | `tool_not_called` | The specified tool was not invoked | | `exit_status` | Run completed with the expected status (`success` or `error`) | ### Running Tests ```bash # Run a test suite initrunner test role.yaml -s test_suite.yaml # Dry-run tests (no API calls, uses TestModel) initrunner test role.yaml -s test_suite.yaml --dry-run # Verbose output initrunner test role.yaml -s test_suite.yaml -v ``` | Flag | Type | Default | Description | |------|------|---------|-------------| | `-s, --suite` | `str` | *(required)* | Path to the test suite YAML | | `--dry-run` | `bool` | `false` | Use TestModel instead of real API calls | | `-v, --verbose` | `bool` | `false` | Show full output for each test case | ### Test Output ``` Running suite: support-agent-tests (4 tests) ✓ answers_product_question (1.2s, 340 tokens) ✓ rejects_off_topic (0.8s, 95 tokens) ✓ uses_search_tool (2.1s, 520 tokens) ✗ stays_within_budget FAIL: max_tokens — expected ≤4096, got 4301 Results: 3 passed, 1 failed (4.1s total) ``` > **Looking for the full eval framework?** See [Agent Evals](/docs/evals) for LLM judge assertions, concurrent execution, tag-based filtering, JSON output, and more. ## Testing Workflow A practical workflow for developing and testing agents: 1. **Validate** — catch schema errors early: ```bash initrunner validate role.yaml ``` 2. **Dry-run** — verify tool registration and config without API calls: ```bash initrunner run role.yaml --dry-run -p "Test prompt" ``` 3. **Interactive test** — manual testing in REPL mode: ```bash initrunner run role.yaml -i ``` 4. **Suite test** — run automated assertions against real model output: ```bash initrunner test role.yaml -s tests/regression.yaml ``` 5. **CI integration** — validate and dry-run in CI, suite tests on schedule: ```bash # In CI pipeline initrunner validate role.yaml initrunner test role.yaml -s tests/smoke.yaml --dry-run ``` ### Agent Evals # Agent Evals InitRunner's eval framework lets you define test suites in YAML and run them against agent roles to verify output quality, tool usage, performance, and cost. Suites can be run manually, in CI pipelines, or as part of a development workflow. ## Quick Start Create a test suite YAML file: ```yaml apiVersion: initrunner/v1 kind: TestSuite metadata: name: web-searcher-eval cases: - name: basic-search prompt: "What is Docker?" assertions: - type: contains value: "container" case_insensitive: true - type: not_contains value: "error" ``` Run it: ```bash initrunner test examples/roles/web-searcher.yaml -s eval-suite.yaml --dry-run -v ``` ## Assertion Types ### `contains` / `not_contains` Check whether the output includes (or excludes) a substring. ```yaml assertions: - type: contains value: "Docker" case_insensitive: true # default: false - type: not_contains value: "I don't know" ``` ### `regex` Match a regular expression against the output. ```yaml assertions: - type: regex pattern: "\\b\\d{3}-\\d{4}\\b" ``` ### `tool_calls` Verify which tools the agent called during the run. ```yaml assertions: - type: tool_calls expected: ["web_search"] mode: subset # default ``` Modes: - **`subset`** — all expected tools must appear in actual calls (extras allowed) - **`exact`** — actual and expected must match exactly (as sets) - **`superset`** — actual calls must be a subset of expected (no unexpected tools) The assertion message includes F1 score (precision/recall) for diagnostics. ### `max_tokens` Cap the total token usage for a test case. ```yaml assertions: - type: max_tokens limit: 2000 ``` ### `max_latency` Cap the wall-clock latency in milliseconds. ```yaml assertions: - type: max_latency limit_ms: 30000 ``` ### `llm_judge` Use an LLM to evaluate the output against qualitative criteria. Each criterion is evaluated independently. ```yaml assertions: - type: llm_judge criteria: - "The response explains what Docker volumes are" - "The response includes practical usage examples" model: openai:gpt-4o-mini # default ``` The judge returns pass/fail per criterion with a reason. In `--dry-run` mode, LLM judge assertions are skipped (marked as failed with a `[skipped]` message) to avoid API costs. ## Tags Tag test cases for selective execution: ```yaml cases: - name: search-test prompt: "Find info about Docker" tags: [search, docker] assertions: - type: contains value: "Docker" - name: math-test prompt: "What is 2+2?" tags: [math, fast] assertions: - type: contains value: "4" ``` Run only tagged cases: ```bash initrunner test role.yaml -s suite.yaml --tag search initrunner test role.yaml -s suite.yaml --tag search --tag math ``` Multiple `--tag` values are OR'd — a case runs if it has any of the specified tags. ## Concurrent Execution Run test cases in parallel with `-j`: ```bash initrunner test role.yaml -s suite.yaml -j 4 ``` Each worker thread gets its own agent instance (built from the role file) to avoid shared-state issues. Result ordering is deterministic regardless of completion order. ## JSON Output Save results to a JSON file for CI integration or historical tracking: ```bash initrunner test role.yaml -s suite.yaml -o results.json ``` The output schema: ```json { "suite_name": "my-suite", "timestamp": "2026-02-28T12:00:00+00:00", "summary": { "total": 3, "passed": 2, "failed": 1, "total_tokens": 4500, "total_duration_ms": 12000 }, "cases": [ { "name": "case-1", "passed": true, "duration_ms": 3000, "tokens": {"input": 200, "output": 100, "total": 300}, "tool_calls": ["web_search"], "assertions": [ {"type": "contains", "passed": true, "message": "Output contains 'Docker'"} ], "output_preview": "Docker is a containerization...", "error": null } ] } ``` ## CLI Reference ```bash initrunner test -s [OPTIONS] ``` | Flag | Description | |------|-------------| | `-s`, `--suite` | Path to test suite YAML (required) | | `--dry-run` | Simulate with TestModel, no API calls | | `-v`, `--verbose` | Show assertion details in output | | `-j`, `--concurrency` | Number of concurrent workers (default: 1) | | `-o`, `--output` | Save JSON results to file | | `--tag` | Filter cases by tag (repeatable) | ## CI Usage ```bash # Run evals in CI with dry-run for quick validation initrunner test roles/agent.yaml -s evals/suite.yaml --dry-run # Run real evals with JSON output for tracking initrunner test roles/agent.yaml -s evals/suite.yaml -o eval-results.json -j 4 # Exit code is 1 if any test fails echo $? ``` ## Full Example ```yaml apiVersion: initrunner/v1 kind: TestSuite metadata: name: web-searcher-eval cases: - name: search-query prompt: "Find information about Docker volumes" tags: [search, docker] assertions: - type: contains value: "volume" case_insensitive: true - type: tool_calls expected: ["web_search"] mode: subset - type: llm_judge criteria: - "The response explains what Docker volumes are" - "The response includes practical usage examples" - type: max_tokens limit: 2000 - type: max_latency limit_ms: 30000 - name: no-hallucination prompt: "What is the capital of Atlantis?" tags: [safety] assertions: - type: not_contains value: "the capital of Atlantis is" case_insensitive: true - type: regex pattern: "(?i)(fictional|myth|does not exist|no.+capital)" ``` ## Interfaces ### Dashboard & TUI # Dashboard & TUI InitRunner provides two graphical interfaces for monitoring agents: a **terminal UI (TUI)** for local use and a **web dashboard** for browser-based access. Both give you real-time visibility into agent runs, memory, audit logs, and chat. ## TUI The TUI is a terminal-based dashboard built with [Textual](https://textual.textualize.io/). It runs entirely in your terminal — no browser required. ### Installation ```bash pip install initrunner[tui] ``` Requires `textual>=7.5.0`. ### Launch ```bash initrunner tui ``` ### Panels The TUI provides five panels, navigable with keyboard shortcuts: | Panel | Description | |-------|-------------| | **Agents** | Lists all discovered roles with status (idle, running, daemon). Select an agent to view details or start a run | | **Runs** | Live and historical run log. Shows run ID, agent name, trigger type, status, duration, and token usage | | **Memory** | Browse and search an agent's long-term memories. Filter by category, view similarity scores | | **Audit** | Scrollable audit log with filters for agent name, trigger type, and date range | | **Chat** | Interactive chat panel — select an agent and send prompts directly from the TUI | ### Keyboard Shortcuts | Key | Action | |-----|--------| | `Tab` | Cycle between panels | | `q` | Quit | | `/` | Focus search/filter input | | `Enter` | Select item or send message | | `Esc` | Close modal or clear filter | ## Web Dashboard The web dashboard is a browser-based interface built with FastAPI and Jinja2. It provides real-time monitoring, a chat interface, and role management. ### Installation ```bash pip install initrunner[dashboard] ``` Requires `fastapi`, `uvicorn`, and `jinja2`. ### Launch ```bash initrunner ui initrunner ui --host 0.0.0.0 --port 9000 ``` | Flag | Default | Description | |------|---------|-------------| | `--host` | `127.0.0.1` | Host to bind to | | `--port` | `8420` | Port to listen on | ### Features | Feature | Description | |---------|-------------| | **Agent Overview** | Cards for each discovered role showing name, description, provider, model, and current status | | **Run Monitor** | Real-time run progress with streaming output, tool call trace, and token counters | | **Chat Interface** | Send prompts to any agent and view streaming responses in the browser | | **Role Management** | View and browse role YAML definitions. Installed roles from the registry are listed alongside local roles | | **Audit Viewer** | Searchable, paginated audit log with export to CSV/JSON | | **Memory Browser** | View, search, and delete long-term memories for any agent | | **File Attachments** | Upload or drag-and-drop images, audio, video, and documents into the chat interface. See [Multimodal](/docs/multimodal) | ## Choosing an Interface | | TUI | Web Dashboard | |---|-----|---------------| | **Requires browser** | No | Yes | | **Remote access** | No (local terminal) | Yes (bind to `0.0.0.0`) | | **Real-time streaming** | Yes | Yes | | **Chat** | Yes | Yes | | **Multiple users** | No | Yes | | **File attachments** | `Ctrl+A` | Upload button / drag-and-drop | | **Install size** | Small (`textual`) | Moderate (`fastapi`, `uvicorn`, `jinja2`) | ## Cloud Hosting The web dashboard can be deployed to a cloud platform for always-on remote access. Each platform builds from the same Dockerfile and seeds 5 example roles on first boot. | Platform | Deploy method | Persistent storage | Notes | |----------|--------------|-------------------|-------| | **Railway** | One-click button | Manual volume at `/data` | Builds from `railway.json` | | **Render** | One-click button | 1 GB disk via Blueprint | Auto-provisioned by `render.yaml` | | **Fly.io** | CLI (`fly deploy`) | Volume via `fly volumes create` | Uses `deploy/fly.toml` | > **Tip:** Set `INITRUNNER_DASHBOARD_API_KEY` to password-protect the dashboard when exposing it on a public URL. See [Cloud Deploy](/docs/cloud-deploy) for step-by-step instructions for each platform. ### CLI Reference # CLI Reference ## Commands | Command | Description | |---------|-------------| | `initrunner` | List available commands and usage | | `initrunner chat [role.yaml]` | Zero-config chat, role-based REPL, or one-command bot launcher | | `initrunner run ` | Run an agent (single-shot or interactive) | | `initrunner validate ` | Validate a role, team, or compose definition | | `initrunner init` | Scaffold a template role, tool module, or skill | | `initrunner setup` | Guided setup wizard (provider selection + test) | | `initrunner ingest ` | Ingest documents into vector store | | `initrunner daemon ` | Run in trigger-driven daemon mode | | `initrunner serve ` | Serve agent as an OpenAI-compatible API | | `initrunner test -s ` | Run a test suite against an agent | | `initrunner pipeline ` | Run a pipeline of agents | | `initrunner tui` | Launch TUI dashboard | | `initrunner ui` | Launch web dashboard (requires `[dashboard]` extra) | | `initrunner install ` | Install a role from GitHub or community index | | `initrunner uninstall ` | Remove an installed role | | `initrunner search ` | Search the community role index | | `initrunner info ` | Inspect a role's metadata without installing | | `initrunner list` | List installed roles | | `initrunner update [name]` | Update installed role(s) to latest version | | `initrunner plugins` | List discovered tool plugins | | `initrunner audit prune` | Prune old audit records | | `initrunner audit export` | Export audit records as JSON or CSV | | `initrunner memory clear ` | Clear agent memory store | | `initrunner memory export ` | Export memories to JSON | | `initrunner memory list ` | List stored memories | | `initrunner memory consolidate ` | Run memory consolidation | | `initrunner skill validate ` | Validate a skill definition | | `initrunner skill list` | List available skills | | `initrunner compose up ` | Run compose orchestration (foreground) | | `initrunner compose validate ` | Validate a compose definition | | `initrunner compose install ` | Install systemd user unit | | `initrunner compose uninstall ` | Remove systemd unit | | `initrunner compose start ` | Start systemd service | | `initrunner compose stop ` | Stop systemd service | | `initrunner compose restart ` | Restart systemd service | | `initrunner compose status ` | Show systemd service status | | `initrunner compose logs ` | Show journald logs | | `initrunner compose events ` | Stream compose orchestration events | | `initrunner create ` | Generate a role YAML from a natural-language description using AI | | `initrunner examples list` | List available example roles | | `initrunner examples copy ` | Copy example files to the current directory | | `initrunner examples show ` | Show the primary file of an example with syntax highlighting | | `initrunner doctor` | Check provider configuration, API keys, and connectivity | | `initrunner mcp list-tools ` | List tools available from MCP servers in a role | | `initrunner mcp serve ...` | Expose agents as an MCP server | | `initrunner --version` | Print version | ## Global Options | Flag | Description | |------|-------------| | `--version` | Print version and exit | | `--verbose` | Enable debug logging | ## Chat Options | Flag | Description | |------|-------------| | `role_file` | Path to `role.yaml` (positional, optional).

Send a request with `X-Conversation-Id: conv-001`. 2. The server stores message history after each request. 3. Subsequent requests with the same ID use stored history — only the last user message is the new prompt. 4. Conversations expire after 1 hour of inactivity. ## Authentication When `--api-key` is set, all `/v1/*` endpoints require: ``` Authorization: Bearer ``` The `/health` endpoint is never protected. ## Usage Examples ### curl ```bash curl http://127.0.0.1:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "messages": [{"role": "user", "content": "Hello!"}] }' ``` ### curl (with auth and conversation) ```bash # First message curl http://127.0.0.1:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -H "Authorization: Bearer my-secret-key" \ -H "X-Conversation-Id: conv-001" \ -d '{"messages": [{"role": "user", "content": "My name is Alice."}]}' # Follow-up curl http://127.0.0.1:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -H "Authorization: Bearer my-secret-key" \ -H "X-Conversation-Id: conv-001" \ -d '{"messages": [{"role": "user", "content": "What is my name?"}]}' ``` ### OpenAI Python SDK ```python from openai import OpenAI client = OpenAI( base_url="http://127.0.0.1:8000/v1", api_key="my-secret-key", # or "unused" if no --api-key set ) response = client.chat.completions.create( model="my-agent", messages=[{"role": "user", "content": "Hello!"}], ) print(response.choices[0].message.content) ``` ### OpenAI Python SDK (streaming) ```python from openai import OpenAI client = OpenAI( base_url="http://127.0.0.1:8000/v1", api_key="unused", ) stream = client.chat.completions.create( model="my-agent", messages=[{"role": "user", "content": "Tell me a story."}], stream=True, ) for chunk in stream: if chunk.choices[0].delta.content: print(chunk.choices[0].delta.content, end="") ``` ### OpenAI Node.js SDK ```javascript import OpenAI from "openai"; const client = new OpenAI({ baseURL: "http://127.0.0.1:8000/v1", apiKey: "my-secret-key", }); const response = await client.chat.completions.create({ model: "my-agent", messages: [{ role: "user", content: "Hello!" }], }); console.log(response.choices[0].message.content); ``` ## Open WebUI Integration [Open WebUI](https://github.com/open-webui/open-webui) gives you a ChatGPT-like web interface for any InitRunner agent. Because `initrunner serve` speaks the OpenAI wire format, Open WebUI works out of the box — no plugins or adapters needed. ### Setup This walkthrough uses the `support-agent` example, which includes a RAG knowledge base. **1. Ingest the knowledge base** ```bash initrunner ingest examples/roles/support-agent/support-agent.yaml ``` **2. Start the InitRunner server** ```bash initrunner serve examples/roles/support-agent/support-agent.yaml --host 0.0.0.0 --port 3000 ``` > `--host 0.0.0.0` is required so the Docker container can reach the server. **3. Launch Open WebUI** ```bash docker run -d \ --name open-webui \ --network host \ -e OPENAI_API_BASE_URL=http://127.0.0.1:3000/v1 \ -e OPENAI_API_KEY=unused \ -v open-webui:/app/backend/data \ ghcr.io/open-webui/open-webui:main ``` **4. Open your browser** Navigate to `http://localhost:8080`, create a local account, and select the `support-agent` model from the model dropdown. Start chatting — responses are served by your InitRunner agent. ### Cleanup ```bash docker rm -f open-webui docker volume rm open-webui ``` ### Notes - If you start the server with `--api-key`, set `OPENAI_API_KEY` to the same value in the `docker run` command. - For production deployments, consider running both services behind a reverse proxy with TLS. ### MCP Gateway # MCP Gateway — Expose Agents as MCP Tools The `initrunner mcp serve` command exposes one or more InitRunner agents as an [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) server. This lets Claude Desktop, Claude Code, Cursor, and any other MCP client call your agents directly as tools. InitRunner already supports MCP as a **client** (consuming external MCP servers as agent tools). The gateway adds the reverse direction — your agents become the server. ## Quick Start ```bash # Expose a single agent over stdio (for Claude Desktop / Claude Code) initrunner mcp serve examples/roles/hello-world.yaml # Expose multiple agents initrunner mcp serve roles/researcher.yaml roles/writer.yaml roles/reviewer.yaml # Use SSE transport for network clients initrunner mcp serve roles/agent.yaml --transport sse --host 0.0.0.0 --port 8080 ``` Each role becomes an MCP tool. The tool name is derived from `metadata.name` in the role YAML. When names collide, suffixes (`_2`, `_3`, ...) are appended automatically. ## CLI Options Synopsis: `initrunner mcp serve ROLE_FILES... [OPTIONS]` | Option | Type | Default | Description | |--------|------|---------|-------------| | `ROLE_FILES` | `Path...` | *(required)* | One or more role YAML files to expose as MCP tools. | | `--transport, -t` | `str` | `stdio` | Transport protocol: `stdio`, `sse`, or `streamable-http`. | | `--host` | `str` | `127.0.0.1` | Host to bind to (sse/streamable-http only). | | `--port` | `int` | `8080` | Port to listen on (sse/streamable-http only). | | `--server-name` | `str` | `initrunner` | MCP server name reported to clients. | | `--pass-through` | `bool` | `false` | Also expose the agents' own MCP tools directly (see [Pass-Through Mode](#pass-through-mode)). | | `--audit-db` | `Path` | `~/.initrunner/audit.db` | Path to audit database. | | `--no-audit` | `bool` | `false` | Disable audit logging. | | `--skill-dir` | `Path` | `None` | Extra skill search directory. | ## Transports ### stdio (default) The standard transport for local MCP integrations. The MCP client launches `initrunner mcp serve` as a subprocess and communicates over stdin/stdout. All status output (agent listing, errors) is printed to stderr to keep stdout clean for the MCP protocol. ```bash initrunner mcp serve roles/agent.yaml ``` ### SSE (Server-Sent Events) For network-accessible servers. The MCP client connects via HTTP. ```bash initrunner mcp serve roles/agent.yaml --transport sse --host 0.0.0.0 --port 8080 ``` ### Streamable HTTP Modern HTTP-based transport with bidirectional streaming. ```bash initrunner mcp serve roles/agent.yaml --transport streamable-http --port 9090 ``` ## How It Works 1. At startup, the gateway loads and builds all specified roles (using `load_and_build`). 2. Each agent is registered as an MCP tool with the name from `metadata.name`. 3. When an MCP client calls a tool, the gateway runs the agent with the provided `prompt` string and returns the output. 4. Agent execution errors are returned as error strings — they never crash the MCP server. 5. Audit logging works the same as in other execution modes. ### Tool Naming Tool names are derived from the role's `metadata.name` field. Characters that are not alphanumeric, hyphens, or underscores are replaced with `_`. When multiple roles share the same name, suffixes are appended: | Role Name | Tool Name | |-----------|-----------| | `researcher` | `researcher` | | `writer` | `writer` | | `writer` (duplicate) | `writer_2` | | `my agent!` | `my_agent_` | ### Tool Schema Each registered tool accepts a single parameter: | Parameter | Type | Description | |-----------|------|-------------| | `prompt` | `string` | The prompt to send to the agent. | The tool description is taken from `metadata.description` in the role YAML. ## Client Configuration ### Claude Desktop Add to your `claude_desktop_config.json`: ```json { "mcpServers": { "initrunner": { "command": "initrunner", "args": ["mcp", "serve", "/path/to/roles/agent.yaml"] } } } ``` For multiple agents: ```json { "mcpServers": { "initrunner": { "command": "initrunner", "args": [ "mcp", "serve", "/path/to/roles/researcher.yaml", "/path/to/roles/writer.yaml" ] } } } ``` ### Claude Code Add to your `.mcp.json`: ```json { "mcpServers": { "initrunner": { "command": "initrunner", "args": ["mcp", "serve", "roles/agent.yaml"] } } } ``` ### Cursor Add to your Cursor MCP settings: ```json { "mcpServers": { "initrunner": { "command": "initrunner", "args": ["mcp", "serve", "roles/agent.yaml"] } } } ``` ### Network Clients (SSE / Streamable HTTP) Start the server: ```bash initrunner mcp serve roles/agent.yaml --transport sse --host 0.0.0.0 --port 8080 ``` Then configure your MCP client to connect to `http://:8080`. ## Pass-Through Mode With `--pass-through`, the gateway also exposes MCP tools that the agents themselves consume. This is useful when you want a single MCP server to expose both the agents and their underlying tools. ```bash initrunner mcp serve roles/agent.yaml --pass-through ``` ### How It Works - Only `type: mcp` tools from the role are passed through. Other tool types (shell, filesystem, etc.) are skipped because they require PydanticAI `RunContext`, which doesn't exist outside an agent run. - If no roles have MCP tools configured, `--pass-through` is a no-op. - Pass-through tools are prefixed with `{agent_name}_` to avoid collisions across agents. If the MCP tool config also has a `tool_prefix`, both prefixes are combined. - The role's `tool_filter`, `tool_exclude`, and `tool_prefix` settings are honored. ### Security Pass-through mode applies the same sandbox checks as agent execution: - MCP commands are validated against `security.tools.mcp_command_allowlist`. - Environment variables are scrubbed using `sensitive_env_prefixes`, `sensitive_env_suffixes`, and `env_allowlist` from the role's [security](/docs/security) policy. - Working directories are resolved relative to the role file's directory. ## Multiple Agents Example Create a multi-tool MCP server from several specialized agents: ```bash # roles/researcher.yaml — searches the web and summarizes findings # roles/writer.yaml — writes polished prose from notes # roles/reviewer.yaml — reviews text for clarity and correctness initrunner mcp serve roles/researcher.yaml roles/writer.yaml roles/reviewer.yaml ``` An MCP client (e.g., Claude Desktop) can then orchestrate all three agents as tools within a single conversation. ## Error Handling - **Startup errors**: If any role file fails to load, the gateway exits immediately with a clear error message identifying the problematic file. - **Runtime errors**: Agent execution failures are returned as error strings (`"Error: ..."`) to the MCP client. Unexpected exceptions are caught and returned as `"Internal error: ..."`. The MCP server never crashes due to an agent error. - **Invalid transport**: Rejected at startup with a descriptive error listing the valid options. ## Audit Logging Agent runs through the gateway are audit-logged the same way as any other execution mode. Use `--audit-db` to set a custom database path, or `--no-audit` to disable logging. ```bash # Query audit logs for gateway runs initrunner audit query --agent-name researcher ``` ## Programmatic API The gateway can also be used programmatically: ```python from pathlib import Path from initrunner.mcp.gateway import build_mcp_gateway, run_mcp_gateway mcp = build_mcp_gateway( [Path("roles/agent.yaml")], server_name="my-server", ) run_mcp_gateway(mcp, transport="stdio") ``` Or via the services layer: ```python from pathlib import Path from initrunner.services.operations import build_mcp_gateway_sync mcp = build_mcp_gateway_sync([Path("roles/agent.yaml")]) ``` See the [CLI Reference](/docs/cli) for the full list of `mcp serve` flags. ## Community ### Registry # Registry The InitRunner registry lets you install pre-built roles from GitHub repositories and a community index. Instead of writing every role from scratch, you can search for existing roles, inspect their configuration, and install them with a single command. ## Quick Start ```bash # Search for roles initrunner search "code review" # Inspect before installing initrunner info user/initrunner-code-reviewer # Install initrunner install user/initrunner-code-reviewer # Run the installed role initrunner run code-reviewer -i ``` ## CLI Commands ### Search ```bash initrunner search ``` Searches the community role index by name, description, and tags. Returns matching roles with name, description, author, and install source. ```bash initrunner search "kubernetes" initrunner search "slack notification" initrunner search "rag" ``` ### Info ```bash initrunner info ``` Inspects a role's metadata without installing it. Shows name, description, author, version, tags, dependencies, model requirements, and tools used. ```bash # From GitHub initrunner info user/initrunner-k8s-monitor # From the community index initrunner info k8s-monitor ``` ### Install ```bash initrunner install ``` Installs a role from a GitHub repository or community index entry. ```bash # From GitHub initrunner install user/initrunner-code-reviewer # From community index by name initrunner install code-reviewer ``` | Flag | Description | |------|-------------| | `--force` | Overwrite if already installed | ### List ```bash initrunner list ``` Shows all installed roles with name, version, source, and install date. ``` NAME VERSION SOURCE INSTALLED code-reviewer 1.2.0 user/initrunner-code-reviewer 2025-01-10 k8s-monitor 0.5.1 user/initrunner-k8s-monitor 2025-01-08 slack-notifier 1.0.0 community-index 2025-01-05 ``` ### Update ```bash initrunner update [name] ``` Updates installed roles to their latest version. Without a name, updates all installed roles. ```bash # Update a specific role initrunner update code-reviewer # Update all installed roles initrunner update ``` ### Uninstall ```bash initrunner uninstall ``` Removes an installed role from the local system. ```bash initrunner uninstall code-reviewer ``` ## Install Sources ### GitHub Repositories Any public GitHub repository containing a valid role YAML can be installed directly using `user/repo` shorthand: ```bash initrunner install user/initrunner-my-role ``` The repository should contain a role YAML file at the root level. If the repo contains multiple roles, InitRunner installs all of them. ### Community Index The community index is a curated collection of roles maintained by the InitRunner community in [vladkesler/community-roles](https://github.com/vladkesler/community-roles). Roles in the index can be installed by name: ```bash initrunner install code-reviewer ``` ## Install Location Installed roles are stored in `~/.initrunner/roles/`: ``` ~/.initrunner/roles/ ├── code-reviewer/ │ ├── role.yaml │ ├── SKILL.md │ └── my_tools.py ├── k8s-monitor/ │ └── role.yaml └── slack-notifier/ └── role.yaml ``` Each role gets its own directory containing the role YAML and any associated files (skills, custom tool modules, etc.). Installed roles are discoverable by `initrunner list`, the TUI, and the web dashboard. You can run them directly by name: ```bash initrunner run code-reviewer -i ``` ## Help ### Doctor # Doctor The `doctor` command checks your InitRunner environment — API keys, provider SDKs, and service connectivity — in a single command. With `--quickstart`, it runs a real agent prompt to verify the entire stack end-to-end. ## Quick Start ```bash # Check provider configuration initrunner doctor # Full end-to-end smoke test (makes a real API call) initrunner doctor --quickstart # Test a specific role file initrunner doctor --quickstart --role role.yaml ``` ## CLI Options | Option | Type | Default | Description | |--------|------|---------|-------------| | `--quickstart` | `bool` | `false` | Run a smoke prompt to verify end-to-end connectivity. | | `--role` | `Path` | — | Role file to test. Used for `.env` loading and as the agent for `--quickstart`. | ## Config Scan The config scan runs automatically on every `doctor` invocation. It checks: | Check | What it verifies | |-------|------------------| | **API Key** | Whether the provider's environment variable is set (e.g. `OPENAI_API_KEY`) | | **SDK** | Whether the provider's Python SDK is importable (only checked when key is set) | | **Ollama** | Whether the Ollama server is reachable at `localhost:11434` | | **Docker** | Whether the Docker CLI and daemon are available | Example output: ``` Provider Status ┏━━━━━━━━━━━┳━━━━━━━━━┳━━━━━┳━━━━━━━━━━━━━━━━┓ ┃ Provider ┃ API Key ┃ SDK ┃ Status ┃ ┡━━━━━━━━━━━╇━━━━━━━━━╇━━━━━╇━━━━━━━━━━━━━━━━┩ │ openai │ Set │ OK │ Ready │ │ anthropic │ Missing │ — │ Not configured │ │ google │ Missing │ — │ Not configured │ │ groq │ Missing │ — │ Not configured │ │ mistral │ Missing │ — │ Not configured │ │ cohere │ Missing │ — │ Not configured │ │ ollama │ — │ — │ Ready │ │ docker │ — │ — │ Ready │ └───────────┴─────────┴─────┴────────────────┘ ``` The scan loads `.env` files before checking, so keys defined in `.env` files (project-local or `~/.initrunner/.env`) are detected. If `--role` is provided, the `.env` in the role's directory is loaded first. ## Quickstart Smoke Test With `--quickstart`, the doctor runs a real agent prompt after the config scan: ```bash initrunner doctor --quickstart ``` **What it does:** 1. Detects the available provider (or uses the one from `--role`) 2. Builds a minimal agent (or loads the role file if `--role` is given) 3. Sends a single prompt: "Say hello in one sentence." 4. Reports success or failure with response preview, token count, and duration **On success:** ``` ╭───────────────────────────── Quickstart Result ──────────────────────────────╮ │ Smoke test passed! │ │ │ │ Response: Hello! │ │ Tokens: 97 | Duration: 2229ms │ ╰──────────────────────────────────────────────────────────────────────────────╯ ``` **On failure**, the error is displayed and the command exits with code 1: ``` ╭───────────────────────────── Quickstart Result ──────────────────────────────╮ │ Smoke test failed: Model API error: 401 Unauthorized │ ╰──────────────────────────────────────────────────────────────────────────────╯ ``` ### Testing a specific role Use `--role` to test a specific role file. This loads the role's `.env`, builds the role's agent (with its model, tools, and system prompt), and runs the smoke prompt against it. ```bash initrunner doctor --quickstart --role examples/roles/code-reviewer.yaml ``` This is useful for verifying that a role's provider, model, and SDK configuration work before deploying it. ## Use Cases - **First-time setup**: Run `initrunner doctor` after `initrunner setup` to verify everything is configured. - **CI/CD validation**: Add `initrunner doctor --quickstart` to your CI pipeline to catch provider configuration issues early. - **Debugging**: When a role isn't working, `doctor` quickly shows whether the issue is a missing API key, missing SDK, or unreachable service. - **Multi-provider environments**: See at a glance which providers are configured and ready. ## Exit Codes | Code | Meaning | |------|---------| | `0` | Config scan passed (without `--quickstart`), or smoke test passed | | `1` | Smoke test failed or encountered an error | ### Troubleshooting & FAQ # Troubleshooting & FAQ ## Provider & API Key Issues ### API key not found ``` Error: API key not found for provider 'openai' ``` InitRunner looks for API keys in this order: 1. `spec.model.api_key` in the role file (not recommended for production) 2. Environment variable: `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, `GOOGLE_API_KEY`, etc. 3. `.env` file in the role file's directory 4. `~/.initrunner/.env` global config **Fix:** Export the key or add it to your `.env` file: ```bash export OPENAI_API_KEY=sk-... ``` Or, to persist across sessions, add it to `~/.initrunner/.env`: ```dotenv OPENAI_API_KEY=sk-... ``` ### Model not found ``` Error: Model 'gpt-5-turbo' not found for provider 'openai' ``` **Fix:** Check the model name matches your provider's available models. Run: ```bash initrunner models --provider openai ``` See [Providers](/docs/providers) for supported models per provider. ### Rate limiting / 429 errors ``` Error: Rate limit exceeded (429) ``` **Fix:** - Reduce `max_tokens_per_run` or `max_tokens` to limit output length per call - Add `iteration_delay_seconds` in autonomous mode to space out requests - Switch to a higher-tier API plan - Use a different model (e.g., `gpt-4o-mini` instead of `gpt-4o`) --- ## Tool Execution Failures ### Tool not found ``` Error: Tool 'search_documents' is not registered ``` **Fix:** This usually means the tool wasn't configured in `spec.tools`, or for `search_documents`, you haven't added an `spec.ingest` section. Run `initrunner ingest role.yaml` after adding ingestion config. ### Permission denied (filesystem) ``` Error: Access denied: path '/etc/passwd' is outside allowed root ``` Filesystem tools are sandboxed to `root_path`. You cannot access files outside the configured directory. **Fix:** Update `root_path` in your filesystem tool config, or use an absolute path that falls within the allowed root. ### Shell command blocked ``` Error: Command 'rm' is not in the allowed commands list ``` Shell tools restrict which commands can run via `allowed_commands`. **Fix:** Add the command to the allowlist in your role file: ```yaml tools: - type: shell allowed_commands: - curl - rm # add the command you need ``` ### MCP connection failed ``` Error: Failed to connect to MCP server at localhost:3001 ``` **Fix:** - Verify the MCP server is running and listening on the expected port - Check that the `url` in your MCP tool config matches the server address - Test connectivity: `curl http://localhost:3001/health` --- ## Memory & Ingestion Problems ### No documents ingested ``` search_documents returned: "No documents have been ingested yet" ``` **Fix:** Run the ingestion pipeline before querying: ```bash initrunner ingest role.yaml ``` Make sure your `spec.ingest.sources` glob patterns match actual files: ```bash # Test the glob pattern ls docs/**/*.md ``` ### Memory not persisting between sessions Session history (short-term) only lasts for the duration of a single session or daemon run. To recall facts across sessions, enable semantic memory: ```yaml spec: memory: semantic: max_memories: 1000 ``` **Note:** Short-term session history is separate — use `--resume` to reload it. The `remember()` and `recall()` tools operate on the semantic memory store above. See [Memory](/docs/memory) for the full schema and all memory types (semantic, episodic, procedural). ### Embedding errors ``` Error: Failed to generate embeddings ``` **Fix:** - Check that the embedding provider API key is set - Verify the embedding model exists (e.g., `text-embedding-3-small` for OpenAI) - If using a different provider for embeddings than for the main model, set `ingest.embeddings.provider` explicitly --- ## YAML Configuration Mistakes ### Missing required fields ``` Error: 'spec.role' is required ``` Every role file needs at minimum: ```yaml apiVersion: initrunner/v1 kind: Agent metadata: name: my-agent spec: role: Your system prompt here. model: provider: openai name: gpt-4o-mini ``` ### Indentation errors YAML is indentation-sensitive. Use 2 spaces (not tabs). Common mistakes: ```yaml # Wrong — tools is not under spec spec: role: ... tools: # should be indented under spec - type: shell # Correct spec: role: ... tools: - type: shell ``` ### Environment variable substitution Variables like `${SLACK_WEBHOOK_URL}` are resolved at runtime from the environment. If they resolve to empty strings: **Fix:** - Export the variable: `export SLACK_WEBHOOK_URL=https://hooks.slack.com/...` - Add it to `.env` in the role file's directory - For systemd/compose deployments, use the environment file (see [Compose](/docs/compose)) --- ## Autonomous Mode Issues ### Infinite loops / agent won't stop **Cause:** The agent keeps creating new plan steps or never calls `finish_task`. **Fix:** Set guardrails to enforce limits: ```yaml guardrails: max_iterations: 5 autonomous_token_budget: 30000 max_tool_calls: 15 autonomy: max_plan_steps: 6 iteration_delay_seconds: 2 ``` The agent will stop when any limit is reached. ### Empty or vague plans **Cause:** The system prompt doesn't give the agent clear enough instructions on what to do. **Fix:** Be specific in `spec.role` about the expected workflow: ```yaml role: | You are a deployment checker. Follow these steps exactly: 1. Use update_plan to create a verification checklist 2. Run curl for each endpoint 3. Mark each step passed or failed 4. Call finish_task with the overall result ``` See [Autonomy](/docs/autonomy) for best practices. ### Token budget exceeded too quickly **Cause:** The `autonomous_token_budget` is too small for the task complexity, or the agent is making many tool calls that produce large outputs (shell commands, HTTP responses, file reads). **Fix:** - Increase `autonomous_token_budget` to give the agent more room - Lower `model.max_tokens` to reduce per-response output - Reduce `max_tool_calls` to limit tool invocations per iteration - Use more specific tool configs (e.g., narrower `allowed_commands`, smaller file reads) to reduce output volume ### Scheduled follow-ups lost on daemon restart **Cause:** Tasks scheduled via `schedule_followup` or `schedule_followup_at` are held in-memory only. When the daemon process stops or restarts, all pending scheduled tasks are discarded. **Fix:** - Use cron triggers for predictable recurring work instead of `schedule_followup` - For critical follow-ups, have the agent persist the schedule externally (file, database, or message queue) and use a cron trigger to poll for pending work - If running under systemd, configure `Restart=on-failure` to minimize unexpected restarts --- ## Daemon & Trigger Issues ### Cron not firing **Fix:** - Verify the cron expression is valid (5-field format: `min hour day month weekday`) - Check `timezone` — defaults to `UTC` - Make sure the daemon is running: `initrunner daemon role.yaml` - Check audit logs for errors: `sqlite3 ~/.initrunner/audit.db "SELECT * FROM events ORDER BY created_at DESC LIMIT 10"` ### File watcher not detecting changes **Fix:** - Ensure the `paths` directory exists before starting the daemon - Check `extensions` filter — an empty list watches all files, a populated list only watches those extensions - Increase `debounce_seconds` if events are being swallowed by rapid consecutive changes - Verify `process_existing: true` if you want existing files to be processed on startup ### Webhook not receiving events **Fix:** - Confirm the port is not already in use: `ss -tlnp | grep 8080` - Test locally: `curl -X POST http://127.0.0.1:8080/webhook -d '{"test": true}'` - If using HMAC verification (`secret`), ensure the sender includes a valid `X-Hub-Signature-256` header - Check firewall rules if the sender is on a different host See [Triggers](/docs/triggers) for full configuration. --- ## Compose Issues ### Circular dependency detected ``` Error: Circular dependency: a -> b -> c -> a ``` **Fix:** Redesign the service graph so that data flows in one direction. The most common approaches are: 1. **Remove the back-edge** — identify which delegation is redundant and drop it. 2. **Introduce an intermediary** — instead of A delegating to B and B delegating back to A, have both delegate to a third service C. Example of a circular config and how to break it: ```yaml # Broken — a and b delegate to each other services: a: role: roles/a.yaml sink: { type: delegate, target: b } b: role: roles/b.yaml sink: { type: delegate, target: a } # circular! # Fixed — b writes to a file sink instead of delegating back services: a: role: roles/a.yaml sink: { type: delegate, target: b } b: role: roles/b.yaml sink: { type: file, path: output/result.txt } ``` If b genuinely needs to pass results back upstream, use a shared file, database, or message queue as an intermediary rather than a delegate sink. ### Delegate sink not connecting ``` Error: Delegate target 'consumer' not found in services ``` **Fix:** The `target` name in a delegate sink must exactly match a service name defined in `spec.services`. Check for typos. ### Services not starting in order **Fix:** Add `depends_on` to enforce startup ordering: ```yaml services: producer: role: roles/producer.yaml sink: { type: delegate, target: consumer } consumer: role: roles/consumer.yaml depends_on: [producer] ``` See [Compose](/docs/compose) for the full orchestration guide. --- ## Performance Tips - **Choose the right model** — Use `gpt-4o-mini` or equivalent for simple tasks. Reserve larger models for complex reasoning. - **Limit guardrails to what you need** — Overly aggressive `max_tool_calls` or `max_tokens_per_run` can cause agents to stop before finishing useful work. - **Use `read_only: true`** on filesystem tools when agents only need to read files. This skips confirmation prompts and reduces overhead. - **Tune chunking for RAG** — Smaller chunks (`256-512`) give more precise search results. Larger chunks (`1024+`) provide more context but may dilute relevance. - **Use `paragraph` chunking for prose** — It preserves document structure better than `fixed` chunking for documentation and articles. - **Add `iteration_delay_seconds`** in autonomous mode to avoid hitting rate limits. --- ## FAQ ### Can I use multiple providers in one agent? Not within a single agent — each agent is bound to one `spec.model` provider. However, you can use [Compose](/docs/compose) to orchestrate multiple agents, each with a different provider. ### Can I run agents offline? Yes, if you use a local provider like [Ollama](/docs/providers). All other features (tools, memory, ingestion) work without an internet connection. Only the LLM API calls require connectivity (unless running locally). ### Where is my data stored? | Data | Default Location | |------|-----------------| | Audit logs | `~/.initrunner/audit.db` | | Memory | `~/.initrunner/memory/.db` | | Ingestion vectors | `~/.initrunner/stores/.db` | | Session state | In-memory (lost on exit) | ### How do I reset memory? Delete the memory database file: ```bash rm ~/.initrunner/memory/my-agent.db ``` Or re-ingest documents to rebuild the vector store: ```bash initrunner ingest role.yaml ``` ### Can I use InitRunner in CI/CD? Yes. Use single-shot mode with `-p` to pass a prompt and capture the output: ```bash initrunner run role.yaml -p "Analyze the latest test results" --output json ``` Set API keys as CI environment variables. See [Testing](/docs/testing) for test automation patterns. ### How do I update InitRunner? ```bash pip install --upgrade initrunner ``` Or with extras: ```bash pip install --upgrade "initrunner[ingest]" ```
