Code Review

Review $ARGUMENTS thoroughly, covering all dimensions of code quality:

Review Checklist

Correctness

• Does the code do what it's supposed to do?
• Are there edge cases that aren't handled?
• Are there off-by-one errors, null/undefined risks, or race conditions?
• Is error handling correct and complete?

Design

• Is the code at the right level of abstraction?
• Does it follow existing patterns in the codebase?
• Is there unnecessary complexity or over-engineering?
• Are responsibilities clearly separated?
• Could this be simpler?

Readability

• Are variable/function names clear and descriptive?
• Is the code self-documenting? Are comments explaining "why" not "what"?
• Is the control flow easy to follow?
• Are functions short and focused?

Performance

• Are there obvious performance issues (N+1 queries, unnecessary loops)?
• Is there unnecessary memory allocation?
• Are expensive operations cached or batched?

Security

• Is user input validated and sanitized?
• Are there injection risks?
• Are secrets handled properly?

Testing

• Are the changes tested?
• Do tests cover edge cases?
• Are tests readable and maintainable?
• Do tests test behavior, not implementation?

Output Format

For each issue:

1. Location: File and line number
2. Severity: blocker | suggestion | nit
3. Description: What's wrong and why
4. Suggestion: How to fix it (with code if helpful)

End with a summary: overall assessment, key strengths, and top priorities to address.
