Can it help with React Server Components (RSC)?

Yes, it includes specific high-priority rules for server-side performance, data serialization, and parallel fetching in RSC environments.

How does this skill improve bundle sizes?

It identifies heavy components for dynamic loading, manages barrel imports, and suggests strategies for deferring third-party scripts until after hydration.
