About

Reviews merge requests, resolves work items and tasks autonomously, and chats with full project context — remembering what matters so every run builds on the last.

Battle-tested in production since mid-2026 — 133 releases, 1k+ reviews, 67% comment acceptance rate (Sept 29 2026, see snapshot). Development history → every failure and fix, documented.

Four harnesses, one shared foundation:

Shared foundation: every drafted comment is screened before it posts; a run that misbehaves (repeats a call, loops, ends on a question, skips a check) gets caught and corrected mid-run — backed by persistent checkpoints, so a run resumes instead of restarting from scratch.
