Use when building Next.js 16 apps — Turbopack, App Router, Cache Components, proxy.ts, v15 migration. Not for stack scaffolding (nextjs-stack) or React SPA (react-expert).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<objective>
Covers Next.js 16 core framework mechanics (current stable: 16.3): Turbopack (default bundler; Webpack remains available via the `--webpack` opt-out flag), the App Router (nested layouts, parallel/intercepting routes, file conventions like page.tsx/layout.tsx/loading.tsx/error.tsx/not-found.tsx), Cache Components (`use cache`, `cacheTag()`, `cacheLife()`, `revalidateTag()`), `proxy.ts` (full Node.js runtime, replaces Edge middleware), and React 19 integration (View Transitions, new hooks).

Documents the critical v15→v16 breaking changes: proxy.ts replacing middleware.ts, Turbopack as the default for `next dev`/`next build`, `cacheComponents` replacing the removed `experimental.ppr` flag, required React 19, and async `params`/`searchParams`. This skill covers core framework APIs only — for assembling a full production stack (Prisma, Better Auth, shadcn/ui, Zustand together) use nextjs-stack instead; for a pure React SPA without `next.config.*` use the react-expert skills instead.

How to install

The exact contents, by fingerprint

mdr add fusengine/agents/nextjs-16@sha256:3a127033919f168b

The line at the top of this page pins the label git:20260927.43a351c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
