概要
The MERN Code Reviewer skill transforms Claude into a specialized senior architect for full-stack JavaScript applications. It follows a structured, priority-based workflow—starting with project health and build status before diving deep into security vulnerabilities like NoSQL injection, performance bottlenecks like N+1 queries, and maintainability issues like 'god files.' By combining general code quality principles with MERN-specific best practices, it provides actionable reports that categorize issues from critical blockers to architectural suggestions, ensuring your codebase remains production-ready and scalable.
