What it does

When installed, the agent reviews code more systematically. It checks for security problems (authentication, data exposure, injection, weak cryptography, sensitive data in logs), performance issues (algorithm complexity, memory, database queries, caching, concurrency), and code quality (SOLID principles, design patterns, naming, documentation, test coverage, readability, function length, complexity). It then reports a summary with a 1-5 quality score, and lists issues by severity with file locations and suggested fixes. The skill is a written review checklist and output template; it contains no scripts.

Great for

  • Developers who want a second pair of eyes on a pull request or code change
  • Teams wanting a consistent review format with severity levels and suggested fixes
  • Anyone doing a quick security or performance pass on a module before release

Skip it if

  • Replacing a human security audit or penetration test, since the checklist only guides the model's review and cannot guarantee that no vulnerabilities remain
  • Reviewing code in regulated or safety-critical systems without expert sign-off, because findings and scores are model judgments

Try asking

  • “Review this pull request for security and performance problems”
  • “Analyze the code quality of the auth module and suggest refactors”
  • “Check this function for injection risks and sensitive data in logs”
  • “Give me a code review summary with a 1-5 quality score”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Point the agent at specific files or a diff so it can cite file names and line numbers accurately.
  • Say which concern matters most (for example security only) to get a focused review instead of a broad one.
  • Treat the severity ratings and quality score as a starting point and verify critical findings yourself.
