Secondsky Claude Skills Design System Creation

Design System Creation

Build comprehensive design systems for consistent UI development across teams.

Design System Layers

1. Foundation: Colors, typography, spacing, elevation
2. Components: Buttons, inputs, cards, navigation
3. Patterns: Forms, layouts, empty states

Foundation - Design Tokens

:root {
  /* Colors */
  --color-primary-50: #eff6ff;
  --color-primary-500: #3b82f6;
  --color-primary-900: #1e3a8a;

  /* Semantic colors */
  --color-success: #22c55e;
  --color-warning: #f59e0b;
  --color-error: #ef4444;

  /* Typography */
  --font-sans: 'Inter', system-ui, sans-serif;
  --font-mono: 'Fira Code', monospace;

  /* Type scale */
  --text-xs: 0.75rem;
  --text-sm: 0.875rem;
  --text-base: 1rem;
  --text-lg: 1.125rem;
  --text-xl: 1.25rem;
  --text-2xl: 1.5rem;

  /* Spacing (4px base) */
  --space-1: 0.25rem;
  --space-2: 0.5rem;
  --space-4: 1rem;
  --space-8: 2rem;

  /* Elevation */
  --shadow-sm: 0 1px 2px rgba(0,0,0,0.05);
  --shadow-md: 0 4px 6px rgba(0,0,0,0.1);
  --shadow-lg: 0 10px 15px rgba(0,0,0,0.1);

Component Documentation

## Button

### Anatomy
- Container (padding, background)
- Label (text)
- Icon (optional)

### Variants
- Primary: Main actions
- Secondary: Alternative actions
- Ghost: Subtle actions

### States
- Default, Hover, Active, Disabled, Loading

### Accessibility
- Role: button
- Keyboard: Enter/Space to activate
- Focus: Visible focus ring

Component Example (React)

interface ButtonProps {
  variant?: 'primary' | 'secondary' | 'ghost';
  size?: 'sm' | 'md' | 'lg';
  loading?: boolean;
  disabled?: boolean;
  children: React.ReactNode;
}

function Button({ variant = 'primary', size = 'md', loading, disabled, children }: ButtonProps) {
  return (
    <button
      className={`btn btn-${variant} btn-${size}`}
      disabled={disabled || loading}
      aria-busy={loading}
    >
      {loading ? <Spinner /> : children}
    </button>
  );
}

Governance

• Review Committee: Approves new components
• Contribution Process: RFC → Review → Implementation
• Versioning: Semantic versioning for releases
• Deprecation: 3-month notice with migration guide

Best Practices

• Start with foundational tokens
• Document every component thoroughly
• Ensure WCAG 2.1 AA compliance
• Support dark mode from the start
• Include usage guidelines with do/don't examples
