When to use
- You said "review this PR", "what's missing in this diff", "I want a critical second pair of eyes before merging".
- You're about to merge and want a last pass before CI.
What it does
Reads the diff and returns:
- Real bugs (not style): off-by-one, race conditions, missing error handling, leaks.
- Architectural risks: changes that touch something critical without tests.
- Forgotten edge cases: the typical list a senior would catch.
- Verdict: ship / fix-first / no-ship with concrete reasoning.
No lint, no "consider using TypeScript", no "add more comments". Straight to the point.
How to use
- Paste the diff (
git diff main...HEAD) or pass the PR URL. - If you want context, add: "this code handles payments, watch for concurrency."
- Read the output; key items are marked 🔴 (blocker), 🟡 (review), 🟢 (ok).
Best for
Solo devs without a review team, juniors who want to simulate senior review, teams that have CI for lint but no human reviewer on call.
