# Design System Skill

This skill automatically activates when working with design systems, component libraries, or reusable UI patterns. It ensures consistency and promotes component reuse across projects.

## Core Principle

**BUILD ONCE, USE EVERYWHERE**

```
❌ Duplicating UI code across components
✅ Building reusable, documented design system components
```

## Automatic Behaviors

When this skill activates, Claude will:

### 1. Identify Design System Opportunities

Automatically detect when code could benefit from design system patterns:

| Pattern | Detection | Recommendation |
|---------|-----------|----------------|
| Repeated styles | Same CSS in multiple places | Extract to design token |
| Similar components | Components with slight variations | Create variant system |
| Magic numbers | Hard-coded values (colors, spacing) | Replace with tokens |
| Inconsistent naming | Different names for same concept | Standardize naming |
| Missing documentation | Undocumented components | Add usage docs |

### 2. Design Token Architecture

```
DESIGN TOKEN STRUCTURE
════════════════════════════════════════════════════════════

PRIMITIVE TOKENS (Raw Values)
└── color.blue.500: "#3b82f6"
└── space.4: "16px"
└── font.size.base: "16px"

SEMANTIC TOKENS (Purpose-Based)
└── color.primary: "{color.blue.500}"
└── spacing.component: "{space.4}"
└── text.body: "{font.size.base}"

COMPONENT TOKENS (Component-Specific)
└── button.background: "{color.primary}"
└── button.padding: "{spacing.component}"
└── button.fontSize: "{text.body}"
```

### 3. Component Structure

```
COMPONENT ORGANIZATION (Atomic Design)
════════════════════════════════════════════════════════════

src/components/
├── atoms/                    # Smallest building blocks
│   ├── Button/
│   ├── Input/
│   ├── Icon/
│   └── Text/
│
├── molecules/                # Combinations of atoms
│   ├── FormField/
│   ├── SearchBox/
│   └── Card/
│
├── organisms/                # Complex UI sections
│   ├── Header/
│   ├── Sidebar/
│   └── DataTable/
│
└── templates/                # Page layouts
    ├── DashboardLayout/
    └── AuthLayout/
```

### 4. Component File Structure

```
Button/
├── Button.tsx           # Component implementation
├── Button.styles.ts     # Styles (CSS modules or styled)
├── Button.types.ts      # TypeScript interfaces
├── Button.test.tsx      # Unit tests
├── Button.stories.tsx   # Storybook documentation
└── index.ts             # Public exports
```

## Warning Triggers

Automatically warn user when:

1. **Hard-coded values detected**
   > "⚠️ DESIGN SYSTEM: Consider replacing hard-coded value with design token"

2. **Duplicate styles found**
   > "⚠️ DESIGN SYSTEM: This style exists in [component]. Consider extracting to shared token"

3. **Missing documentation**
   > "⚠️ DESIGN SYSTEM: Component missing Storybook story or usage documentation"

4. **Inconsistent naming**
   > "⚠️ DESIGN SYSTEM: Naming pattern differs from existing components"

5. **Component too complex**
   > "⚠️ DESIGN SYSTEM: Consider breaking this into smaller atomic components"

## Design System Checklist

```
📋 Design System Audit

□ TOKENS
  □ Color primitives defined
  □ Semantic color tokens exist
  □ Spacing scale consistent
  □ Typography scale defined

□ COMPONENTS
  □ Atomic structure followed
  □ Components are documented
  □ TypeScript types defined
  □ Accessibility tested

□ PATTERNS
  □ Layout patterns documented
  □ Form patterns standardized
  □ Error handling consistent
  □ Loading states defined
```
