Can it fix async waterfalls automatically?

Yes, the skill identifies sequential 'await' calls that can be parallelized using Promise.all() or deferred to prevent network latency accumulation.

Does it help reduce JavaScript bundle size?

Absolutely. It enforces direct imports over barrel files and suggests dynamic loading for heavy components to improve initial page load times and Time to Interactive.

What kind of rendering optimizations are included?

The skill covers re-render optimization, CSS content-visibility for long lists, SVG hoisting, and preventing hydration mismatches without causing layout shifts.

How does this skill help with Next.js performance?

It provides specific rules for optimizing React Server Components (RSC), implementing strategic Suspense boundaries, and minimizing serialization overhead at server-client boundaries.
