Nextjs Code Review

This one walks through your Next.js App Router code and flags issues with Server/Client Component boundaries, data fetching waterfalls, caching strategies, Server Actions security, and middleware scope. It's built for pre-merge reviews or architectural validation when you're unsure if you've pushed 'use client' too high up the tree or exposed sensitive operations. The examples are solid: it shows you how to parallelize fetches, add proper validation to Server Actions, and scope middleware with matchers instead of running auth checks on every static asset. It delegates to a separate TypeScript architecture agent for broader structural analysis, so think of this as the Next.js-specific layer that catches framework footguns before they hit production.
