Code Review

This is the code reviewer you'd want on your team. It systematically checks your code across four main areas: quality (readability, DRY principle, organization), best practices (language idioms, error handling), security (OWASP Top 10, input validation), and performance (algorithm efficiency, caching). The output is structured into severity-ranked issues, actionable suggestions with examples, and positive feedback on what you did right. It uses file reading tools to actually inspect your codebase rather than just talking theory. Most useful when you're about to merge something significant or inheriting a codebase and need to understand what you're dealing with. The security focus alone makes it worth having around.
