Cloudflare Workers performance optimization with CPU, memory, caching, bundle size. Use for slow workers, high latency, cold starts, or encountering CPU limits, memory issues, timeout errors.
Code splitting and lazy loading with React.lazy, Suspense, route-based splitting, intersection observer, and preload strategies for optimal bundle performance. Use when implementing lazy loading or preloading.
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.
Best practices and guidelines for Webpack module bundler configuration, optimization, and development workflows
Web Vitals, Lighthouse CI, bundle optimization, CDN, caching, and load testing
Diagnoses and fixes UI performance across loading speed, rendering, animations, images, and bundle size. Use when the user mentions slow, laggy, janky, performance, bundle size, load time, or wants a faster, smoother experience.
Coordinates code modernization: OSS replacement and bundle optimization workers
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.
Use when writing or debugging code that imports vue-i18n (Vue 3 internationalization). Covers createI18n, useI18n, message syntax, i18n-t/i18n-n/i18n-d components, pluralization, datetime and number formatting, TypeScript schemas, lazy loading, bundle optimization, and v10/v11/v12 migration.
Use when building or auditing web pages for speed: Core Web Vitals (LCP, INP, CLS), Lighthouse and PageSpeed scores, render-blocking resources, bundle size, fonts and caching. Not for visual design (sheleg-design) or conversion work. Opt out: no wiring, без обвязки. Triggers - "PageSpeed", "Lighthouse", "Core Web Vitals", "bundle size", "performance budget", "ускорить сайт", "медленно грузится", "вес бандла".
Audit and reduce Next.js browser initial-load work. Use for slow route startup, oversized client bundles, duplicate browser dependencies, or features that can wait for interaction.
