Fix Next.js waterfall fetching by parallelizing independent fetches to eliminate sequential chains. This Skill audits App Router code, detects waterfall patterns, and guides targeted optimizations for faster data loading.

Add authentication to Next.js Server Actions by verifying user identity inside each action before processing. This Skill includes shell scripts to scan your codebase and detect Server Actions missing proper authentication checks.

React cache enables per-request data deduplication by memoizing fetch results within a single server render pass. Use it in Next.js App Router projects when overlapping data requests cause redundant queries and increased latency.

Yes, this Skill audits Next.js RSC serialization and Suspense boundaries. It detects excessive RSC payloads and identifies where to introduce Suspense boundaries to improve Time to First Byte and perceived loading performance.

Run a performance audit by scanning your app directory for anti-patterns like barrel imports, missing Server Action auth, and sequential fetches. This Skill provides shell scripts and a reusable template to produce a prioritized report.

Minimize Next.js RSC payload size by reducing serialized data passed from Server Components to Client Components. This Skill provides diagnostic guidance and pattern references with examples showing what to serialize and what to avoid.
