Good for

  • Checking a change for bugs and edge cases
  • Reviewing code for readability and maintainability
  • Spotting performance or security concerns

Overview

What it does

This skill guides a review of code for correctness, maintainability, performance, and security. It helps check whether code behaves as expected, handles edge cases, and contains obvious bugs. It also considers whether variable and function names are clear and whether documentation is appropriate. Security checks include input validation, injection vulnerabilities, and secret management. Feedback should explain why a change is needed and offer an alternative, while also acknowledging good work.

When it helps

Use it to look for issues in changed code or prepare clear, specific review comments for a team. It can also help keep review criteria consistent and communicate both improvements and positive aspects of the work.

Example requests

  • “Review this change for correctness, maintainability, performance, and security.”
  • “Check the edge cases and input handling, and suggest fixes.”

Review Checklist

When reviewing code, consider:

Correctness

  • Does the code do what it's supposed to do?
  • Are edge cases handled?
  • Are there any obvious bugs?

Maintainability

  • Is the code easy to understand?
  • Are variable and function names descriptive?
  • Is there appropriate documentation?

Performance

  • Are there any obvious performance issues?
  • Are expensive operations cached when appropriate?
  • Are database queries efficient?

Security

  • Is user input validated?
  • Are there any injection vulnerabilities?
  • Are secrets properly managed?

Giving Feedback

  • Be specific and actionable
  • Explain why something should change
  • Suggest alternatives, don't just criticize
  • Acknowledge good work too
