react-performance
React and Next.js performance optimization patterns adapted from Vercel Engineering's React Best Practices (https://github.com/vercel-labs/agent-skills). Organizes 70+ rules across 8 priority categories — waterfalls, bundle size, server-side, client fetching, re-render, rendering, JS micro-perf, advanced. Use when writing, reviewing, or refactoring React/Next.js code for performance.

# React Performance
Performance optimization patterns for React 18/19 and Next.js, adapted from [Vercel Labs `react-best-practices`](https://github.com/vercel-labs/agent-skills/tree/main/skills/react-best-practices) (MIT, v1.0.0). This skill organizes rules by priority and provides decision-tree guidance for active code review and refactoring.
## When to Activate
- Writing or reviewing React/Next.js code for performance
- Diagnosing slow page loads, slow interactions, or high CPU on the client
- Auditing bundle size or Lighthouse Core Web Vitals regressions
- Removing waterfalls in Server Components / API routes
- Reducing client-side re-renders
- Optimizing long lists, animations, or hydration
- Auditing optimization choices in PRs touching `app/`, `pages/`, `components/`, or data layers
