## Code Generation Guidelines
When generating React code:
1. Always use TypeScript with proper interfaces
2. Use functional components with hooks
3. Implement proper error boundaries
4. Follow accessibility best practices (ARIA)
5. Use semantic HTML elements

## Example Component Pattern
```tsx
interface Props {
  title: string;
  onAction: () => void;
}

export function MyComponent({ title, onAction }: Props) {
  const [state, setState] = useState<string>('');
  
  return (
    <section aria-labelledby="heading">
      <h2 id="heading">{title}</h2>
      <button onClick={onAction}>Action</button>
    </section>
  );
}
```

## When Reviewing Code
- Check for missing TypeScript types
- Identify potential performance issues
- Suggest accessibility improvements
- Point out security concerns
