About
Critic is a code review platform from Feyn that lets reviewers talk directly with the AI agent that wrote a change instead of just reading the diff. A Codex or Claude Code plugin has the agent write a narrative behind each change and annotate key blocks with evidence like screenshots, and every feature is exposed over MCP so a reviewer's question forks the original authoring session and forwards it there, keeping the main thread clean.
At a glance
Critic puts a change narrative, diffs and reviewer questions together for agent-written code. It is worth a pilot if reviewers regularly need to ask why a change was made and the author’s coding session has context missing from the pull request.
Good fit
GitHub teams reviewing agent-generated changes that need explanation alongside the diff.
Consider something else when
Skip it if review patches and local change snapshots must stay off a hosted service.
Start here
Use a disposable repository and one small, known change. Compare the narrative with the actual diff, then ask a question whose answer you can verify in the code.
Cost and requirements
The product offers GitHub sign-in and uses a GitHub App for selected repositories. The local bridge supplies change context. Check plan terms before rolling it out to a team.
Limits to know
The policy says Critic receives patches, change snapshots and review discussion while raw transcripts stay local. Asking a connected agent a question can send relevant review and repository context to that agent’s provider.
Still unclear
- What plan limits and prices apply to a team rollout?

Why it made the leaderboard
Instead of reverse-engineering intent from a diff, Critic lets reviewers chat directly with the agent that wrote the change, forking its original session so you get the actual reasoning behind a decision rather than a guess.
