Agent Skills: react-best-practices

Comprehensive React and Next.js performance optimisation guide with 40+ rules for eliminating waterfalls, optimising bundles, and improving rendering. Use when optimising React or Next.js apps, reviewing performance, refactoring components, hunting wasteful re-renders, reducing bundle size, debugging client/server data-fetching, or tightening rendering paths. Do NOT use for non-React frameworks (Vue, Svelte, Solid, Angular), React Native, or general JavaScript performance unrelated to React.
