Metis

State-driven engineering orchestrator with bounded subagents and verification.

Repository-level engineering orchestrator that delegates bounded discovery, planning, implementation, review, and verification to fresh subagents, isolates mutable tasks in Git worktrees with declared path ownership, and requires evidence-gated completion Metis is an autonomous repository orchestrator that stops AI coding agents from falsely claiming they are finished. Instead of stuffing large multi-file changes into a single bloated context window, Metis breaks tasks into verifiable graphs, delegates bounded slices to fresh subagents in isolated Git worktrees, and controls execution through a deterministic SQLite runtime state machine. With native continuation hooks, durable PRD and planning workflows, and independent verification subagents, Metis ensures your code is actually tested and verified before marking a job complete. It runs entirely locally on Node.js and SQLite.
