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 Composition Patterns Composition patterns for building flexible, maintainable React components. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. These patterns make codebases easier for both humans and AI agents to work with as they scale. ## When to Apply Reference these guidelines when: - Refactoring components with many boolean props - Building reusable component libraries - Designing flexible component APIs - Reviewing component architecture - Working with compound components or context providers ## Rule Categories by Priority | Priority | Category | Impact | Prefix | | -------- | ----------------------- | ------ | --------------- | | 1 | Component Architecture | HIGH | `architecture-` | | 2 | State Management | MEDIUM | `state-` | | 3 | Implementation Patterns | MEDIUM | `patterns-` | | 4 | React 19 APIs | MEDIUM | `react19-` | ## Quick Reference ### 1.

How to install
mdr add vercel-labs/agent-skills/vercel-composition-patterns@sha256:e38e0eaa609316b1The 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.
