Reviewers of agent-written PRs can question the author directly instead of reverse-engineering intent, and the forked session cannot write to anything.
Critic is a code review site from Feyn, a YC-backed San Francisco team. A Codex or Claude Code plugin makes the agent publish a narrative of its change, with hooks that stop it finishing a turn until the write-up meets length and format checks. Reviewers read that on critic.run and chat with a read-only fork of the same agent session. Sign-in is with GitHub, permissions mirror GitHub's, and the makers say it is free to use.
