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

<!-- Generated by scripts/compile-react-guidance.ts. Edit rules/ or metadata.json instead. -->

**Version 1.0.0**  
Vercel Engineering  
January 2026

Use [SKILL.md](SKILL.md) and only the rules relevant to the task. This compiled reference is for deliberate full-guide reading. Apply optimizations only for a supported performance mechanism; ratings and example gains are not measurements of the current application.

Repository-maintained React and Next.js guidance adapted from Vercel's rules. Select rules by a concrete performance mechanism and workload. Dependencies and caches are conditional options, and impact ratings prioritize investigation rather than establish application performance gains.

How to install

The exact contents, by fingerprint

mdr add marcellocurto/skills/skills/vercel-react-best-practices/AGENTS.md@sha256:d98648d77bbad1b0

The line at the top of this page pins the label git:20261002.427fecc, 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.
