name: Code Review description: A comprehensive guide and set of instructions for performing code reviews on the codebase.

Code Review Skill

This skill provides a structured approach to reviewing code. Use this when asked to review code or when you want to ensure the quality of changes before finalizing them.

1. Preparation

• Understand the Goal: Read the user request and any associated task artifacts to understand what the code is supposed to do.
• Context: Ensure you have the latest context. Run git status or check the file content if unsure.

2. Review Checklist

Functionality

• Correctness: Does the code do what it claims to do?
• Edge Cases: Are edge cases handled (e.g., null values, empty lists, error states)?
• Bugs: Are there any obvious bugs?

Code Quality

• Readability: Is the code easy to understand? Are variable names descriptive?
• Complexity: Is the logic overly complex? Can it be simplified?
• Duplication: Is there repeated code that should be refactored into a function or component?
• Comments: Are complex sections commented? Are comments accurate?

Style & consistency

• Conventions: Does the code follow the project's existing coding style?
• Formatting: Is the indentation and spacing consistent?

Performance

• Efficiency: Are there any obvious performance bottlenecks (e.g., nested loops, unnecessary re-renders in React)?
• Resources: Are resources (files, connections) properly managed/closed?

Security

• Input Validation: Is user input validated?
• Secrets: Are there any hardcoded secrets or API keys? (Flag immediately!)

3. Action Items

• If you find issues, document them clearly.
• If you can fix them easily and it's within the scope of your current task, fix them.
• If they are outside the scope or require user decision, list them as feedback.

4. Tools

• Use grep_search to find usages of changed functions to ensure no breaking changes.
• Use run_command to run tests if available (npm test, etc.).
• Use view_file to examine related files.
