Munchkins
Autonomous coding agents that ship — not chatbots that suggest.
Drop a description of the work in. Get a merged commit out. Every run is sandboxed in a fresh git worktree, gated by lint + typecheck + scenario, and only fast-forwarded into your branch when the gate goes green. Plug in claude or codex as the backend; swap freely per run.
The default agents are working examples. Your goal is building agents for your codebase — the new-munchkin skill gets you there in one session.
- Three default agents out of the box —
bug-fix,feat-small,refactor. Each one is a full pipeline, not a single Claude call. - Build your own.
AgentBuilderlets you compose steps, deterministic gates, summary writers, sandboxes, and integration strategies. New agents auto-appear in--help. - Resume, schedule, delegate. Interrupted runs resume from disk. Cron specs run agents on their own. The
launch-munchkinClaude Code skill hands work off in one sentence.
