What problem does it solve?

This Skill helps developers rapidly improve frontend performance by addressing Core Web Vitals, bundle size, and render efficiency across modern web apps.

Core Features & Use Cases

  • Core Web Vitals optimization: LCP, INP/FID, and CLS improvements.
  • Bundle size reduction: Code splitting, tree shaking, asset optimization.
  • Rendering optimization: SSR/CSR strategies, virtualization, skeleton UIs, caching.
  • Image optimization and caching: Next/Image, CDN, responsive images.
  • Measurement and budgets: Lighthouse, Web Vitals, performance budgets, CI/CD checks.

Quick Start

  • Run a performance audit on your Next.js/React app.
  • Implement initial optimizations: enable image optimization, adopt code-splitting, apply skeleton UI, and establish a Lighthouse/Web Vitals monitoring routine.
