What it does

This skill tells the agent to review code in a structured way. When you ask for a code review, a quality check or a pull request review, the agent looks at security issues (such as injection, weak cryptography and sensitive data in logs), performance (algorithm cost, memory, database queries, caching, concurrency), code quality (SOLID principles, naming, docs, test coverage) and maintainability (readability, function length, complexity, dependencies, type safety). Each piece of code gets an overall 1-5 score, a list of key findings with severity, and suggested fixes, following a fixed report template.

Great for

  • Developers who want a second pair of eyes on a pull request before merging
  • Teams that want consistent review reports with severity levels and a score
  • Developers learning which security and performance issues to watch for

Skip it if

  • Safety-critical or regulated code that needs a certified audit, since the agent's review is advisory and can miss issues or report false positives
  • Judging whether code truly works: the skill describes review criteria but does not run tests or the code itself

Try asking

  • “Review this pull request diff for security and performance problems”
  • “Give me a code quality score and key findings for this Python module”
  • “Check this login handler for authentication and injection risks”

  3. 3

    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

  • Paste or point to the specific files or diff you want reviewed, and mention the language and framework so the findings are relevant.
  • Say which area matters most (for example security only) to get a shorter, more focused report.
  • Treat the score and severity labels as a starting point and confirm critical findings yourself or with tests.
