SKILL.md

Description This skill provides comprehensive performance optimization guidance for React applications, optimized for AI-assisted workflows in 2026. It focuses on eliminating waterfalls, leveraging the React Compiler, and maximizing both server and client-side efficiency through modern APIs (use, useActionState, ).

| import { Icon } from 'large-lib' | import Icon from 'large-lib/Icon' | | await a(); await b(); | Promise.all([a(), b()]) | | useEffect(() => { fetch(...) }, []) | const data = use(dataPromise) | | const [state, set] = useState(init()) | useState(() => init()) | | array.sort() | array.toSorted() |

| searchParams in component body | searchParams only in callbacks | | Manual useMemo/useCallback (mostly) | Trust React Compiler (but check Rules of React) |

Senior specialist in React 19.2+ performance, React Compiler (Forget), and advanced architectural patterns. Use when optimizing re-renders, bundle size, data fetching waterfalls (cacheSignal), or server-side efficiency (PPR). Source: yuniorglez/gemini-elite-core.
