Code Review

Review code changes for security vulnerabilities, performance issues, and correctness. Catches N+1 queries, injection risks, missing edge cases, and error handling gaps before they reach production.

The Code Review skill acts as a senior engineer pair-reviewer. It analyzes diffs and PRs for security vulnerabilities, logic errors, performance anti-patterns, and style issues. It provides structured feedback organized by severity so you can triage quickly.

When to use

Trigger with a PR URL or diff, 'review this before I merge', 'is this code safe?', or when checking a change for security or correctness issues.

Examples

Review a pull request

Paste a GitHub PR URL or diff to get structured feedback

Review this PR for security and correctness: https://github.com/org/repo/pull/42

Check for SQL injection

Analyze code for injection vulnerabilities

Is this code safe? Review for injection risks and missing input validation.
