React and Next.js performance optimization from Vercel Engineering. Use when building React components, optimizing performance, eliminating waterfalls, reducing bundle size, reviewing code for performance issues, or implementing server/client-side optimizations.
Comprehensive React and Next.js performance optimization guide with 40+ rules for eliminating waterfalls, optimizing bundles, and improving rendering. Use when optimizing React apps, reviewing performance, or refactoring components.
Analyze and optimize React component performance issues (slow renders, re-render thrash, laggy lists, expensive computations). Use when asked to profile or improve a React component, reduce re-renders, or speed up UI updates in React apps.
React performance optimization guidelines. Use when writing, reviewing, or refactoring React components to ensure optimal rendering and bundle patterns. Triggers on tasks involving React components, hooks, memoization, or bundle optimization.
Use when React Context patterns for state management. Use when sharing state across component trees without prop drilling.
Client-side React performance optimization patterns.
React performance optimization guidelines from Vercel Engineering. This skill should be used proactively when writing, reviewing, or refactoring React code to ensure optimal performance patterns. Triggers on tasks involving React components, bundle optimization, or performance improvements.
Performance optimization patterns covering Core Web Vitals, React render optimization, lazy loading, image optimization, backend profiling, and LLM inference. Use when improving page speed, debugging slow renders, optimizing bundles, reducing image payload, profiling backend, or deploying LLMs efficiently.

React 성능 최적화 및 베스트 프랙티스 스킬. Vercel Engineering 가이드 기반, 프레임워크 비종속. 다음 상황에서 사용: (1) React 컴포넌트(.tsx, .jsx) 작성 또는 수정 시, (2) 상태 관리, hooks, 리렌더링 최적화 작업 시, (3) 비동기 데이터 페칭 또는 Suspense 패턴 작업 시, (4) 번들 사이즈 최적화 또는 코드 스플리팅 시, (5) 'react', 'useState', 'useEffect', 'useMemo', 'useCallback', 'memo', 'Suspense', 'lazy' 키워드가 포함된 작업 시
Security-first PR review checklist for this repo. Use when reviewing diffs/PRs, especially changes involving auth, networking, sensitive data, or dependency/lockfile updates. Focus on secret/PII leakage risk, supply-chain risk (npm + node_modules inspection), cross-platform architecture (extension/mobile/desktop/web), and React performance (hooks + re-render hotspots). Avoid UI style nitpicks. PR Review.
Application-level React performance optimization covering React Compiler mastery, bundle optimization, rendering performance, data fetching, Core Web Vitals, state subscriptions, profiling, and memory management. Use when optimizing React app performance, analyzing bundle size, improving Core Web Vitals, or profiling render bottlenecks. Complements the react skill (API-level patterns) with holistic performance strategies. Does NOT cover React 19 API usage (see react skill) or Next.js-specific features (see nextjs-16-app-router skill).
