code-reviewer_skill

Overview

This skill performs thorough code reviews to identify bugs, security issues, maintainability problems, and adherence to best practices. I provide actionable feedback, prioritized issues, and concrete suggestions so developers can improve code quality quickly. Reviews are concise, specific, and tailored to the project context.

How this skill works

I read and understand the code’s intent, then inspect it for correctness, edge cases, and common bug patterns. I check for security vulnerabilities, performance pitfalls, and style or architectural anti-patterns. Output is structured into an overall assessment, a categorized list of issues with locations, specific suggestions (often with example fixes), and a summary of positives.

When to use it

• You want a peer-style code review before merging a pull request
• You need feedback on code quality, readability, or test coverage
• You suspect a bug or security issue and want targeted checks
• You want suggestions for refactoring or performance improvements
• You are aligning code to team or industry best practices

Best practices

• Provide the code context (files, intent, input/output) to get focused feedback
• Include tests, sample inputs, and expected behavior for tricky logic
• Ask for specific focus areas (security, performance, style) when needed
• Prefer small, self-contained diffs to enable precise review comments
• Iterate on suggestions: I give concrete changes you can apply and re-check

Example use cases

• Review a pull request to find regressions, missing edge cases, or test gaps
• Scan a new authentication or input-handling module for security issues
• Suggest refactors to reduce cyclomatic complexity and improve readability
• Validate performance hotspots and recommend cheaper algorithms or caching
• Assess adherence to language idioms and team coding standards
