react-pro
React (professional)
Skill text is English; answer in the user’s preferred language when rules or the conversation specify it.
Use official React docs for API truth; this skill encodes rendering discipline, effect correctness, accessibility defaults, and SSR/hydration awareness — not framework-specific routing or server cache (see nextjs-pro). Confirm React major, meta-framework (Vite/Next/Remix), and SSR vs SPA when known.
Boundary
react-pro owns React component model (hooks, JSX, composition, web DOM semantics, client-side performance patterns, hydration on the web). nextjs-pro owns Next.js App Router, RSC, fetch caching, middleware, and deployment-shaped React. react-native-pro owns React Native / Expo platform APIs. testing-pro owns test pyramid and CI beyond component examples.
