automission 0.2.2

Multi-agent autonomous mission execution — give it a goal, an agent team collaborates to deliver results

automission

Give it a goal. An agent team autonomously collaborates to deliver results.

Decentralized (no orchestrator), no human-in-the-loop.

Features

• Goal in, results out — describe what you want; Planner generates an acceptance checklist with dependencies, agents do the rest
• Multi-agent collaboration — agents work in parallel on independent groups, coordinate via shared git + SQLite
• Multi-backend — agents, Planner, and Critic all support Claude Code, Codex CLI, and Gemini CLI — mix and match freely
• Docker-first — all execution runs inside containers for isolation and reproducibility
• Daemon mode — --detach to start in background, attach to reconnect, stop/resume to control
• Safety rails — circuit breakers on cost, time, and iterations; 3-step stall detection auto-recovers stuck agents

Quick Start

1. Install

pip install automission

Requires Docker at runtime — all agent execution and verification runs inside containers.

2. Setup

automission init

Interactive setup walks you through:

1. Agent backend — choose claude, codex, or gemini, then pick auth method (API key or OAuth)
2. Planner backend — choose independently, then pick auth method
3. Verifier backend — defaults to planner settings, or configure separately
4. Docker image — checks Docker availability and pulls the agent image

This creates ~/.automission/config.toml:

[defaults]
backend = "claude"
model = "claude-sonnet-4-6"

[planner]
backend = "claude"
model = "claude-sonnet-4-6"

[verifier]
backend = "claude"
model = "claude-sonnet-4-6"

[keys]
# Set your API keys here or via environment variables
# anthropic = "sk-ant-..."    # or ANTHROPIC_API_KEY
# codex = "sk-..."            # or CODEX_API_KEY
# gemini = "..."              # or GEMINI_API_KEY

Manual setup (without init)

# Set the API key for your chosen backend
export ANTHROPIC_API_KEY=sk-ant-...   # for Claude (default)
export CODEX_API_KEY=sk-...           # for Codex
export GEMINI_API_KEY=...             # for Gemini

3. Run

automission run --goal "Build a TODO API with auth"

Planner auto-generates an acceptance checklist with dependencies. Review it, confirm, and agents start working.

More options

# Choose model
automission run --goal "..." --model opus

# Multi-agent, choose backend
automission run --goal "..." --agents 3 --backend codex

# Use a different Planner backend
automission run --goal "..." --planner-backend gemini --planner-model gemini-2.5-pro

# Auto-approve Planner output (skip Y/n/edit prompt)
automission run --goal "..." -y

# Skip Planner — provide your own acceptance criteria
automission run --goal "..." --no-planner --acceptance acceptance.md --verify verify.sh

# Goal from file
automission run --goal-file mission-brief.md

# Start in background
automission run --goal "..." --detach

Key flags:

Flag	Default	Description
--backend	claude	Agent backend: claude, codex, gemini
--model	sonnet	Model for agent execution (#38)
--planner-backend	claude	Backend for Planner/Critic
--planner-model	claude-sonnet-4-6	Model for Planner
--agents	2	Number of parallel agents
-y	—	Auto-approve Planner output
--no-planner	—	Skip Planner (requires --acceptance)
--max-cost	10.0	Max total cost in USD
--timeout	3600	Max wall-clock seconds
--api-key	—	API key override (skips env/config lookup)
--detach	—	Start mission and return immediately

4. Monitor & Control

automission status              # mission overview
automission logs -f             # stream attempt logs
automission attach <mission-id> # reconnect to a running mission
automission stop                # stop most recent running mission
automission stop <mission-id>   # stop a specific mission
automission resume <mission-id> # resume a stopped or crashed mission
automission list                # list all missions

How It Works

1. You give a goal — one sentence or a detailed spec
2. Planner expands it into an acceptance checklist with dependencies
3. Agents work the frontier — groups whose dependencies are satisfied
4. Each attempt: agent reads mission context + receives dynamic feedback from last verification
5. Verifier checks: verify.sh gates pass/fail, LLM critic provides structured feedback
6. Atomic merge: verified work lands on main safely (staging ref + regression check)
7. Loop continues until all acceptance groups pass or circuit breakers trigger

Authentication

API key lookup order (first match wins):

1. --api-key flag (per-command override)
2. Environment variable (ANTHROPIC_API_KEY, CODEX_API_KEY, GEMINI_API_KEY)
3. ~/.automission/config.toml under [keys]

Backend	Env Var	Config Key
claude	ANTHROPIC_API_KEY	keys.anthropic
codex	CODEX_API_KEY	keys.codex
gemini	GEMINI_API_KEY	keys.gemini

OAuth: Codex and Gemini support OAuth login. Run automission init and choose oauth when prompted — the CLI will trigger the OAuth flow for the selected backend and mount the token directory into Docker containers automatically.

Key Design Decisions

Decision	What	Why
No orchestrator	Agents coordinate via shared state (git + SQLite), not a central LLM	Fault tolerant, no single point of failure
Multi-backend	Claude, Codex, Gemini behind a common protocol	Not locked to one vendor; use the best model for the job
Docker-first	All LLM calls and verify.sh run inside containers	Isolation, reproducibility, secure API key handling
CLI-based Planner/Critic	Planner and Critic call LLM via CLI (--json-schema), not SDK	Unified auth (API key or OAuth), no SDK dependency
Gate + Critic	verify.sh decides pass/fail; LLM analyzes why and suggests next steps	Objective gate + actionable feedback
Acceptance checklist	Criteria with dependencies form a DAG; agents work the frontier	Parallel when possible, sequential when needed
Atomic merge	Staging ref + regression verify + fast-forward	Bad merge never poisons main
Fresh session per attempt	Each attempt is a new agent session	Resumable, reproducible, no context pollution
Attempt contract	Auto-derived focus for each attempt	Directed improvement, not blind retry
