Can it help refactor existing React components?

Yes, the skill is designed to analyze existing code and provide optimized refactors for state management, data fetching, and component structure.

Does it support the Next.js App Router?

Yes, it includes specific patterns for server components, async/await in layouts, and Suspense boundaries which are essential for the App Router architecture.

How does this skill help with Next.js performance?

It applies 55 specific rules curated by Vercel that target common bottlenecks like network waterfalls, large bundle sizes, and inefficient rendering patterns.

Will this help reduce my application's bundle size?

Absolutely. It triggers rules for identifying barrel imports, implementing dynamic imports for heavy components, and deferring non-critical third-party scripts.
