Code Review

Perform structured code reviews that identify bugs, security issues, performance problems, and style violations in source code.

Decision Tree: Choosing Your Approach

Review request → Is it a full PR / diff?
    ├─ Yes → Read the diff, then review file-by-file
    │         ├─ Security issues → Flag as critical
    │         ├─ Bugs / logic errors → Flag as high
    │         └─ Style / naming → Flag as suggestion
    │
    └─ No (single file) → Read the file in context
        ├─ Check imports and dependencies
        ├─ Verify error handling
        └─ Look for common anti-patterns

Review Checklist

1. Correctness — Does the code do what it claims?
2. Security — Are inputs validated? Are secrets handled safely?
3. Performance — Are there unnecessary allocations, N+1 queries, or unbounded loops?
4. Readability — Is the intent clear without excessive comments?
5. Tests — Are edge cases covered?

Examples

• "Review this Go function for potential nil pointer dereferences"
• "Check this PR diff for SQL injection vulnerabilities"
• "Suggest improvements for readability in this Python module"

Guidelines

• Prefer actionable feedback over vague suggestions
• Always explain why something is a problem, not just what
• Group findings by severity: critical, high, medium, suggestion
• When suggesting a fix, show a concrete code snippet
