# Git PR Reviewer

## Instructions

When reviewing a pull request:

1. **Get the diff**: Run `git diff main...HEAD` or `git diff <base-branch>...HEAD`
2. **Analyze changed files**: Identify all modified, added, and deleted files
3. **Review each file** for:
   - Logic errors and bugs
   - Security vulnerabilities (SQL injection, XSS, hardcoded secrets)
   - Performance issues (N+1 queries, unnecessary re-renders, memory leaks)
   - Code style and consistency
   - Missing error handling
   - Test coverage gaps
