Build reusable, accessible React components with predictable APIs and ref forwarding. Use when creating or refactoring components or defining component APIs, favoring composition over configuration and slots/children over many boolean props. Not needed for style-only or content-only edits that do not change a component API.

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 Component Development — Skill

**Name:** `react-component-dev`
**Purpose:** Build reusable, accessible React components with predictable APIs and ref forwarding.
Use this skill when creating or refactoring components.

**Applies when:** Building new components, refactoring UI components, or defining component APIs.
**Do not use when:** Only editing styles or content in existing components without API changes.

## Rules

- **Composition over configuration:** Prefer `children`/slots over many boolean props.
- **Forward refs:** If a component renders a DOM element, use `forwardRef`.
- **Accessibility:** Use semantic HTML first; add ARIA only when needed.
- **Predictable props:** Follow controlled/uncontrolled conventions.
- **Small and testable:** Extract complex behavior into hooks.

## Workflow

1. Define the component’s responsibility and minimal usage.
2. Choose the API shape (controlled vs uncontrolled as needed).
3. Implement with semantic HTML and accessibility defaults.
4. Add `forwardRef` for DOM-rendering components.
5. Extract complex behavior into hooks if needed.

## Checklists

### Implementation checklist

- [ ] Component has a single responsibility

How to install

The exact contents, by fingerprint
mdr add asymmetric-al/core/react-component-dev@sha256:8c4d521e62754039

The line at the top of this page pins the label git:20260603.c42511a, 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.
