MUST be used whenever optimizing a Dune app for speed, reducing render counts, improving CDF query efficiency, or reducing bundle size. Do NOT skip measurement steps — always profile before changing code. Triggers: performance, slow, laggy, optimize, optimization, re-render, bundle size, load time, Lighthouse, profiler, virtualization, lazy load, code split, CDF query, large list, memory leak.
React and Vite performance optimization guidelines. Use when writing, reviewing, or optimizing React components built with Vite. Triggers on tasks involving Vite configuration, build optimization, code splitting, lazy loading, HMR, bundle size, or React performance.
React rendering performance patterns. Use when reducing re-renders, optimizing memoization, state design, or reviewing React performance.
React/Next.js 앱의 성능을 분석하고 최적화하는 스킬. 번들 사이즈, 렌더링 최적화, 코드 분할, 이미지 최적화, SSR/SSG 전략 등. "성능", "performance", "최적화", "느려", "번들 사이즈", "렌더링" 등의 요청 시 사용.
Load PROACTIVELY when task involves optimizing speed, reducing bundle size, or improving responsiveness. Use when user says "make it faster", "reduce bundle size", "fix slow queries", "optimize rendering", or "check Core Web Vitals". Covers bundle analysis and tree-shaking, database query optimization (N+1, indexing), React rendering performance (re-renders, memoization), network waterfall optimization, memory leak detection, server-side performance, and Core Web Vitals (LCP, FID, CLS) improvement.
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.
Optimize application performance - bundle size, API response times, database queries, React rendering, and serverless function performance. Use when investigating slow pages, profiling, load testing, or before production deployments.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Avoid unnecessary useEffect in React components. Most uses of useEffect are anti-patterns — derived state, event-driven logic, data fetching, and external store subscriptions all have better, more idiomatic alternatives. Apply this skill when writing or reviewing React components that use useEffect.
React performance optimization patterns - React.memo, useMemo, useCallback, code splitting, and preventing unnecessary re-renders
React performance optimization guidelines. Use when writing, reviewing, or refactoring React components, hooks, effects, data fetching, or bundle optimization. Includes useEffect best practices — when NOT to use effects and better alternatives. Triggers: "when writing React code", "reviewing a React PR", "why is this component re-rendering", "reviewing code for performance issues", "optimizing bundle size".
