Does it cover both client and server components?

Yes, it includes specific guidelines for React Server Components (RSC) and client-side rendering patterns, including hydration mismatch prevention.

What are the highest priority optimizations this skill handles?

The skill prioritizes eliminating network waterfalls and bundle size optimization as critical, followed by high-impact server-side performance improvements.

How does this skill improve Next.js performance?

It applies specific rules to eliminate async waterfalls, optimize bundle sizes via dynamic imports, and implement server-side caching strategies based on Vercel Engineering standards.

Can I use this for existing React projects?

Yes, it is specifically designed for both writing new components and refactoring existing code to meet modern performance benchmarks.
