initrunner 1.35.1

Define AI agent roles in YAML and run them anywhere — CLI, API server, or autonomous daemon

InitRunner

Website · Docs · InitHub · Discord · Issues

Define AI agents in YAML. Run them as CLI tools, Telegram bots, Discord bots, API servers, or autonomous daemons. Built-in RAG, persistent memory, 40+ tools, policy-based authorization. Any model.

One YAML file is all it takes to go from idea to running agent - with document search, persistent memory, and tools wired in automatically. Start with initrunner chat for a zero-config assistant, then scale to bots, pipelines, and API servers without rewriting anything.

v1.35.0 - Tool event observability, compose new scaffolding (pipeline/fan-out/route patterns), --format output control (auto/json/text/rich), --list-templates for role generation. See the Changelog.

Quickstart

curl -fsSL https://initrunner.ai/install.sh | sh -s -- --extras all
initrunner setup        # wizard: pick provider, model, API key
initrunner new "a research assistant that summarizes papers"  # build an agent
initrunner chat --ingest ./docs/   # chat with your docs, memory on by default

Or install with a package manager: uv tool install "initrunner[all]" / pipx install "initrunner[all]". See Installation, Setup, and Chat for details.

Or run with Docker, no install needed:

docker run --rm -it -e OPENAI_API_KEY \
    -v initrunner-data:/data ghcr.io/vladkesler/initrunner:latest chat

See the Docker guide for RAG, Telegram, API server, and more examples.

Define Agent Roles in YAML

When you need more control, define an agent as a YAML file:

apiVersion: initrunner/v1
kind: Agent
metadata:
  name: code-reviewer
  description: Reviews code for bugs and style issues
spec:
  role: |
    You are a senior engineer. Review code for correctness and readability.
    Use git tools to examine changes and read files for context.
  model: { provider: openai, name: gpt-5-mini }
  tools:
    - type: git
      repo_path: .
    - type: filesystem
      root_path: .
      read_only: true

initrunner run reviewer.yaml -p "Review the latest commit"

That's it. No Python, no boilerplate. Using Claude? pipx install "initrunner[anthropic]" and set model: { provider: anthropic, name: claude-opus-4-6 }.

Launch	initrunner tui	initrunner ui
Install	pip install initrunner[tui]	pip install initrunner[dashboard]
Roles	Create from template, edit via forms	Form builder with live preview, AI generate

Why InitRunner

Zero config to start. initrunner chat gives you an AI assistant with persistent memory and document search out of the box. No YAML, no setup beyond an API key.

Config, not code. Define your agent's tools, knowledge base, and memory in one YAML file. No framework boilerplate, no wiring classes together. 20+ built-in tools (filesystem, git, HTTP, Python, shell, SQL, search, email, MCP, think, script, and more) work out of the box. Need a custom tool? One file, one decorator.

Version-control your agents. Agent configs are plain text. Diff them, review them in PRs, validate in CI, reproduce anywhere. Your agent definition lives next to your code.

Prototype to production. Same YAML runs as an interactive chat, a one-shot CLI command, a trigger-driven daemon, or an OpenAI-compatible API. No rewrite when you're ready to deploy.

How It Compares

	InitRunner	Build from scratch	LangChain
Setup	curl -fsSL https://initrunner.ai/install.sh | sh + API key	Install 5-10 packages, write glue code	pip install langchain + adapters
Agent config	One YAML file	Python classes + wiring	Python chains + config objects
RAG	--ingest ./docs/ (one flag)	Embed, store, retrieve, prompt - DIY	Loaders > splitters > vectorstore chain
Bot deployment	--telegram / --discord flag	Build bot framework integration	Separate bot framework + adapter
Model switching	--model flag, aliases, or change YAML	Rewrite client code	Swap LLM class + adjust prompts
Multi-agent	compose.yaml with delegation + auto-routing	Custom orchestration layer	Agent executor + custom routing

What Can You Build?

• A Telegram bot that answers questions about your codebase - point it at your repo, deploy with one flag
• A cron job that monitors competitors and sends daily digests - cron trigger + web scraper + Slack sink
• A document Q&A agent for your team's knowledge base - ingest PDFs and Markdown, serve as an API
• A code review bot triggered by new commits - file-watch trigger + git tools + structured output
• A multi-agent pipeline with auto-routing: intake > researcher / responder / escalator - sense routing picks the right target per message (initrunner examples copy support-desk)
• A personal assistant that remembers everything - persistent memory across sessions, no setup

Features

Start with the code-reviewer above. Each step adds one capability - no rewrites, just add a section to your YAML.

Knowledge & memory

Point at your docs for RAG - a search_documents tool is auto-registered. Add memory for persistent recall across sessions:

spec:
  ingest:
    sources: ["./docs/**/*.md", "./docs/**/*.pdf"]
  memory:
    store_path: ./memory.db
    semantic:
      max_memories: 1000

initrunner ingest role.yaml   # extract | chunk | embed | store
initrunner run role.yaml -i --resume   # search_documents + memory ready

See Ingestion · Memory · RAG Quickstart.

Triggers

Turn it into a daemon that reacts to events - cron, file watch, webhook, heartbeat, Telegram, or Discord:

spec:
  triggers:
    - type: cron
      schedule: "0 9 * * 1"
      prompt: "Generate the weekly status report."
    - type: file_watch
      paths: [./src]
      prompt_template: "File changed: {path}. Review it."

initrunner run role.yaml --daemon   # runs until stopped

See Triggers · Telegram · Discord.

Compose agents

Orchestrate multiple agents into a pipeline - one agent's output feeds into the next. Use strategy: sense to auto-route messages to the right target:

apiVersion: initrunner/v1
kind: Compose
metadata: { name: email-pipeline }
spec:
  services:
    inbox-watcher:
      role: roles/inbox-watcher.yaml
      sink: { type: delegate, target: triager }
    triager:
      role: roles/triager.yaml
      sink: { type: delegate, strategy: sense, target: [researcher, responder] }
    researcher: { role: roles/researcher.yaml }
    responder: { role: roles/responder.yaml }

Run with initrunner compose up pipeline.yaml. See Compose · Delegation.

Security & Authorization

Built-in security with optional Cerbos agent-as-principal policy engine. Agents get Cerbos identity from role.metadata (name, team, tags, author), with tool-level authorization and delegation policy enforced across CLI, compose, daemon, API, and pipeline:

pip install initrunner[authz]
export INITRUNNER_CERBOS_ENABLED=true
export INITRUNNER_CERBOS_AGENT_CHECKS=true  # per-agent identity checks
initrunner run role.yaml   # tool calls + delegation checked against Cerbos policies

Also includes content filtering, PEP 578 sandboxing, Docker isolation, token budgets, and rate limiting out of the box. See Agent Policy · Security · Guardrails.
