Use this skill when building or modifying production-quality user-facing interfaces. Builds accessible, responsive, visually polished UIs with proper component architecture, design system adherence, and WCAG 2.1 AA compliance.

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

# Frontend UI Engineering

## Overview

Build production-quality user interfaces that are accessible, performant, and visually polished. The goal is UI that looks like it was built by a design-aware engineer at a top company — not like it was generated by an AI. This means real design system adherence, proper accessibility, thoughtful interaction patterns, and no generic "AI aesthetic."

## When to Use

- Building new UI components or pages
- Modifying existing user-facing interfaces
- Implementing responsive layouts
- Adding interactivity or state management
- Fixing visual or UX issues

## Component Architecture

### File Structure

Colocate everything related to a component:

```
src/components/
  TaskList/
    TaskList.tsx         # Component implementation
    TaskList.test.tsx    # Tests
    types.ts             # Component-specific types (if needed)
```

### Component Patterns

**Prefer composition over configuration:**

```tsx
// Good: Composable
<Tasks>
  <TaskItem task={task} onToggle={handleToggle} onDelete={handleDelete} />
</Tasks>

// Avoid: Over-configured
<SuperTaskPanel mode="edit" enableDrag={true} showCompleted={false} ... />
```
…
