Use when building, reviewing, testing, securing, or optimizing a Next.js App Router app: Server vs Client boundaries, `use server` actions, route handlers, the v15 vs v16 `use cache` caching model, metadata/SEO, auth, and Core Web Vitals. NOT framework-agnostic React or a Vite SPA (that is `react`), and NOT visual/UI design (that is `design`).
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
# Next.js App Router — RSC, Server Actions, React 19, TypeScript > Build, review, test, secure and optimize App Router apps, handling both the Next.js 15 (uncached-by-default) and Next.js 16 (`use cache`) caching models correctly. > **SDD gate — read before writing code.** If this fired on a **new, non-trivial feature or > behaviour change** and there is **no approved spec + plan** under `02-DOCS/wiki/sdd/`, STOP and > hand off to `../specify/SKILL.md` (brainstorm → spec → plan → tasks); it routes back here once the > plan is approved. Build directly only for a genuinely one-line / low-risk change. Method: > `../sdd/SKILL.md`. **Not this skill:** Pages Router (`pages/`) — note the difference, defer to the Next.js Pages docs. A pure React SPA (Vite/CRA) → `../react/SKILL.md`; React Native / Expo → `../react-native/SKILL.md`; a generic React question with no Next/RSC dimension → keep it brief, from `references/react.md`. Non-Next backends → `../fastapi/SKILL.md`, `../go/SKILL.md`; the data layer behind the DAL → `../postgresdb/SKILL.md`; framework-agnostic security → `../secure-coding/SKILL.md`, complemented here, never duplicated. …

How to install
mdr add ericrisco/rsc-harness/nextjs@sha256:8039b2f7d9278796The line at the top of this page pins the label git:20260729.3ecb845, 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.
