| name | code-reviewer |
| description | Use this agent when you need to conduct comprehensive code reviews focusing on code quality, security vulnerabilities, and best practices. Specifically:\n\n<example>\nContext: Developer has submitted a pull request with changes to critical authentication logic in a TypeScript backend service.\nuser: "Can you review this PR that refactors our authentication system? We need to catch any security issues, performance problems, or maintainability concerns."\nassistant: "I'll conduct a thorough code review examining the authentication logic for security vulnerabilities, checking error handling, validating the refactored patterns against SOLID principles, and assessing whether the changes maintain or improve code quality metrics. I'll provide specific feedback on each concern."\n<commentary>\nInvoke code-reviewer when code has been changed and you need detailed analysis of code quality, security, performance, and maintainability. This is distinct from security-auditor (which focuses narrowly on security) and architect-reviewer (which focuses on system design).\n</commentary>\n</example>\n\n<example>\nContext: Team has merged several features and wants a quality assessment before production deployment.\nuser: "We need a code review of the changes in our payment processing module before we deploy to production. Check for any issues we might have missed."\nassistant: "I'll review the payment processing module systematically: analyzing input validation and error handling, checking for injection vulnerabilities, reviewing error recovery patterns, verifying test coverage, assessing maintainability of the code, and identifying any technical debt or performance concerns. I'll prioritize critical issues and provide constructive feedback."\n<commentary>\nUse code-reviewer for pre-deployment reviews when you need comprehensive quality gates across multiple dimensions (security, performance, maintainability, correctness).\n</commentary>\n</example>\n\n<example>\nContext: New junior developer's code is being integrated and team wants learning-focused feedback.\nuser: "Can you review this TypeScript module my new team member wrote? I want to make sure the code quality is good and they're following our patterns."\nassistant: "I'll review the code for correctness, design patterns, naming conventions, and compliance with your team's standards. I'll also check for common mistakes, suggest improvements where they could learn from, and acknowledge what was done well to provide constructive, educational feedback."\n<commentary>\nInvoke code-reviewer when you want detailed feedback that helps developers grow, ensures standards compliance, and catches issues beyond what automated tools can detect. The feedback is actionable and specific.\n</commentary>\n</example> |
