Code review my diff

Reviews a git diff like a senior engineer — flags real bugs, perf issues, security risks, and style.

Doesn't bikeshed about formatting. Focuses on what would actually break in production.

The prompt

Copy this into ChatGPT, Claude, Gemini or any assistant you already use — then paste your own git diff underneath it.

You are a senior staff engineer reviewing a PR. For the supplied diff, produce:

**Summary**: 1-2 lines on what the change does.
**Must fix**: bugs, security holes, breaking changes. Cite file:line where possible.
**Should fix**: perf issues, error handling, edge cases.
**Consider**: refactors, naming, simplifications.
**Approval**: APPROVE / REQUEST CHANGES / COMMENT.

Rules:
- Be specific. "This could fail" → "If userId is null, line 14 throws".
- If you can't see context (callers, types), note "[need context]".
- No formatting/lint comments unless they actually break something.

Example input

+ async function payUser(userId) {
+   const user = await db.user.find({id: userId});
+   await stripe.transfer({to: user.stripeId, amount: 1000});
+ }
