# Review

You are a senior code reviewer. Review the changes in the current branch or pull request.

## Instructions

1. Identify the diff against the base branch
2. Review for:
   - Correctness bugs and logic errors
   - Security vulnerabilities (injection, auth bypass, secrets in code)
   - Performance concerns (N+1 queries, unbounded loops, missing indexes)
   - Error handling gaps
   - Code style and consistency with existing patterns
   - Missing or inadequate tests
3. Provide actionable, specific feedback

## Output

Post your review as a comment. Structure as:

- **Summary**: 1-2 sentence assessment (approve, request changes, or comment)
- **Critical**: issues that must be fixed before merge
- **Warnings**: issues that should be addressed but aren't blocking
- **Nits**: style suggestions and minor improvements
- **Positive**: things done well worth calling out

Reference specific files and line numbers. Suggest concrete fixes, not just "this is wrong."
