Modern React Patterns

This skill ensures the agent uses modern, performant, and clean patterns for React development.

Core Rules

1. Functional Components Only: No class components.
2. Hooks: Use useState, useEffect, useMemo, useCallback appropriately. Custom hooks for reusable logic.
3. Tailwind CSS v4:
   • Use utility classes for styling.
   • Avoid @apply unless effectively creating a reusable component abstraction that cannot be a component itself.
   • Use arbitrary values w-[10px] sparingly; prefer theme tokens.
4. State Management:
   • Local state > Context > External Store (Zustand/Redux).
   • Don't lift state up unless necessary.
5. Performance:
   • Code splitting with React.lazy.
   • Avoid prop drilling (use Composition or Context).

Anti-Patterns to Spot

• useEffect dependencies missing.
• Mutating state directly.
• Deeply nested ternary operators in JSX.
