React Code Review

What it does

This skill enables AI agents to perform automated code reviews specifically for React applications. It analyzes source code to identify potential bugs, performance issues, and adherence to best practices within the React ecosystem.

When to use it

• Before merging a pull request containing new React components or hooks.
• To audit existing codebases for deprecated APIs like React.createClass or unsafe lifecycle methods.
• When refactoring legacy JavaScript into modern functional components with Hooks.
• To ensure consistent styling patterns (e.g., CSS-in-JS, Tailwind) across a team's frontend work.

Key capabilities

• Identifies common React anti-patterns and logic errors.
• Checks for proper usage of useState, useEffect, and other built-in hooks.
• Validates component structure and prop typing.
• Suggests improvements for performance, such as memoization or avoiding unnecessary re-renders.

Example prompts

• "Review this new Dashboard component for potential memory leaks in the useEffect hook."
• "Analyze the provided code snippet for violations of React's Rules of Hooks."
• "Check if these custom hooks are being used correctly and suggest optimizations."

Tips & gotchas

Ensure the AI agent has access to the full file context or a comprehensive project structure, as isolated snippets may miss critical state dependencies. This skill is specialized for React; it will not effectively review Vue, Angular, or plain JavaScript code without additional configuration.
