Apply Vercel's React and Next.js performance guidance. Use when writing or reviewing React or Next.js code.

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

# Vercel React Best Practices

Repository-maintained React and Next.js guidance adapted from Vercel's rules. Use it to address a concrete performance mechanism in the requested work, not to apply every listed pattern across an application.

## Establish relevance before optimizing

Identify the affected path, realistic workload, and avoidable cost: a dependency waterfall, repeated request, excessive bundle, expensive render, or hot computation. Support that mechanism with code and usage evidence or a representative trace/profile. A rule match or an impact label alone does not justify a change.

Preserve the user's scope, existing architecture, and correctness contracts. Prefer an existing facility or direct code change before adding a library, cache, or abstraction. Leave already-adequate code alone when the proposed optimization has no meaningful expected benefit. Correctness and security obligations do not depend on proving a performance gain.

How to install

The exact contents, by fingerprint

mdr add marcellocurto/skills/vercel-react-best-practices@sha256:cb6f65744277f000

The 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.
