Description

Build, advise on, and review React components and hooks — state, effects, context, Actions (useActionState, useOptimistic, use), refs, Suspense, error boundaries, React Compiler, performance, and component architecture. Use this whenever the user writes or reviews .jsx/.tsx components, asks about hooks, re-renders, state management, "useEffect", forms, or React 19 features, in any framework (Next.js, Vite, Expo/React Native, Remix) — even for small asks like "make this component reusable" or "why does this render twice".
