Provides patterns and code examples for building Next.js 16+ applications with App Router architecture. Use when creating projects with App Router, implementing Server Components and Client Components ("use client"), creating Server Actions for forms, building Route Handlers (route.ts), configuring caching with "use cache" directive (cacheLife, cacheTag), setting up parallel routes (`@slot`) or intercepting routes, migrating to proxy.ts, or working with App Router file conventions…
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 (Next.js 16+)
Build modern React applications using Next.js 16+ with App Router architecture.
## Overview
This skill provides patterns for Server Components (default) and Client Components ("use client"), Server Actions for mutations and form handling, Route Handlers for API endpoints, explicit caching with "use cache" directive, parallel and intercepting routes, and Next.js 16 async APIs and proxy.ts.
## When to Use
Activate when user requests involve:
- "Create a Next.js 16 project", "Set up App Router"
- "Server Component", "Client Component", "use client"
- "Server Action", "form submission", "mutation"
- "Route Handler", "API endpoint", "route.ts"
- "use cache", "cacheLife", "cacheTag", "revalidation"
- "parallel routes", "`@`slot", "intercepting routes"
- "proxy.ts", "migrate from middleware.ts"
- "layout.tsx", "page.tsx", "loading.tsx", "error.tsx", "not-found.tsx"
- "generateMetadata", "next/image", "next/font"
## Quick Reference
| File | Purpose | Directive | Purpose |
|------|---------|-----------|---------|
| `page.tsx` | Route page | `"use server"` | Server Action function |

How to install
mdr add giuseppe-trisciuoglio/developer-kit/nextjs-app-router@sha256:678a88fb1f329130The line at the top of this page pins the label git:20260324.a02e282, 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.
