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 **Version 1.0.0** Vercel Engineering January 2026 > **Note:** > This document is mainly for agents and LLMs to follow when maintaining, > generating, or refactoring React and Next.js codebases. Humans > may also find it useful, but guidance here is optimized for automation > and consistency by AI-assisted workflows. --- ## Abstract Comprehensive performance optimization guide for React and Next.js applications, designed for AI agents and LLMs. Contains 40+ rules across 8 categories, prioritized by impact from critical (eliminating waterfalls, reducing bundle size) to incremental (advanced patterns). Each rule includes detailed explanations, real-world examples comparing incorrect vs. correct implementations, and specific impact metrics to guide automated refactoring and code generation. --- ## Table of Contents 1. [Eliminating Waterfalls](#1-eliminating-waterfalls) — **CRITICAL** - 1.1 [Check Cheap Conditions Before Async Flags](#11-check-cheap-conditions-before-async-flags) - 1.2 [Defer Await Until Needed](#12-defer-await-until-needed) - 1.3 [Dependency-Based Parallelization](#13-dependency-based-parallelization) …

How to install
mdr add asymmetric-al/core/.agents/skills/vercel-react-best-practices/AGENTS.md@sha256:07c71ba70d541066The line at the top of this page pins the label git:20260612.9ac3f47, 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.
