Guide React and Next.js best practices. Use for component boundaries,.
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
# React Best Practices Use this skill when working on React best practices tasks. ## Workflow - Inspect framework version, router, rendering mode, server/client boundaries, and data-fetching path before refactors. - Prefer server components and framework-native caching where the project supports them; avoid unnecessary client state. - Validate with typecheck, lint, tests, and build or route-level smoke checks after behavior changes. - Check whether the project uses the App Router, Pages Router, or another React framework before applying routing, data-fetching, or caching advice. - Keep server/client boundaries explicit: move browser-only state, effects, and event handlers into client components while keeping data access and secret handling server-side. - Look for avoidable data waterfalls, unstable cache semantics, duplicate fetches, and stale invalidation behavior before changing component structure. - Keep rerender boundaries small with stable props, local state ownership, and memoization only where measurement or code shape justifies it. …

How to install
mdr add cruxexperts/localsetup/ls-vercel-react-performance@sha256:174e7be3af922584The line at the top of this page pins the label v1.0, 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.
