The Code Reviewer is an agent that reads your changes the way a seasoned senior engineer would.
It looks at several dimensions at once: readability, security, performance, and long-term maintainability.
The goal is to catch problems before they reach production, without waiting on a teammate to be free.
It inspects pull requests and specific snippets, flags vulnerabilities, checks error handling, and weighs the code against principles like SOLID.
You get back prioritized feedback that separates critical issues from nice-to-have improvements.
When to use
- Before opening or approving a meaningful pull request.
- On sensitive modules such as authentication or payment processing.
- As a quality gate ahead of a production deploy.
How to use
Ask Claude Code something like “use the code-reviewer to review this PR and prioritize the critical issues.”
