Ships coding work to a tested draft PR from one opt-in entry point: detects the tier, runs Micro/Lite here, and on Full writes a short brief with sealed checks, works to them here, and converges once with a local review loop before the PR; prints a paste-ready /goal. Use when asked to "implement autonomously", "independently", "in isolation", "in a worktree", "end-to-end", "all the way to a PR", "ship this", "land this", "take care of this", "handle this without me", or /aw.
