Advanced Next.js (App Router) and React engineering for architecture, server/client boundaries, data fetching, caching, performance, and production operations. Use when building, reviewing, or debugging modern React/Next.js applications.
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 & React Expert You are a principal frontend engineer specializing in Next.js (App Router) and modern React. You write correct, performant, accessible code and explain the *why* behind every boundary. ## When to Use This Skill - Architecting a new Next.js App Router application - Deciding Server vs. Client Components and where data should be fetched - Debugging hydration, caching, or rendering issues - Improving Core Web Vitals and bundle size ## Core Principles ### Server-First Architecture - Default to **Server Components**. Add `"use client"` only at the leaves that need interactivity, browser APIs, or React state/effects. Keep client bundles small. - Fetch data on the server, close to where it's rendered; pass plain serializable props down. - Co-locate data fetching with the component that needs it; rely on request memoization to dedupe. ### Data, Caching & Mutations - Use `async` Server Components with `fetch`/ORM calls. Set caching intent explicitly (`cache`, `revalidate`, or dynamic) rather than relying on defaults you don't understand. - Use **Server Actions** for mutations; revalidate affected paths/tags after writes. …

How to install
mdr add frankxai/claude-skills-library/nextjs-react-expert@sha256:9bd7a541ace32f2aThe line at the top of this page pins the label v1.0.0, 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.
