Description

Build, advise on, and review Next.js App Router code — routing, Server vs Client Components, Server Functions/Actions, data fetching, caching and revalidation (Cache Components, `use cache`, updateTag/revalidateTag), proxy.ts (formerly middleware), metadata, images, fonts, route handlers, and deployment. Use this whenever a project has `next` in package.json or the user mentions Next.js, App Router, `app/` directory, RSC, server actions, proxy/middleware, ISR, or a Next upgrade — even if they only ask to "add a page", "fix this route", or "review my PR".
