Manage your design system — audit for consistency, document components, or design new patterns.

Usage

/design-system audit                    # Full system audit
/design-system document [component]     # Document a component
/design-system extend [pattern]         # Design a new component or pattern

Components of a Design System

Design Tokens

Atomic values that define the visual language:

• Colors (brand, semantic, neutral)
• Typography (scale, weights, line heights)
• Spacing (scale, component padding)
• Borders (radius, width)
• Shadows (elevation levels)
• Motion (durations, easings)

Components

Reusable UI elements with defined:

• Variants (primary, secondary, ghost)
• States (default, hover, active, disabled, loading, error)
• Sizes (sm, md, lg)
• Behavior (interactions, animations)
• Accessibility (ARIA, keyboard)

Patterns

Common UI solutions combining components:

• Forms (input groups, validation, submission)
• Navigation (sidebar, tabs, breadcrumbs)
• Data display (tables, cards, lists)
• Feedback (toasts, modals, inline messages)

Principles

1. Consistency over creativity — The system exists so teams don't reinvent the wheel
2. Flexibility within constraints — Components should be composable, not rigid
3. Document everything — If it's not documented, it doesn't exist
4. Version and migrate — Breaking changes need migration paths

Output — Audit

| [Inconsistent naming] | [List] | [Standard to adopt] |

### Token Coverage
| Category | Defined | Hardcoded Values Found |
|----------|---------|----------------------|
| Colors | [X] | [X] instances of hardcoded hex |
| Spacing | [X] | [X] instances of arbitrary values |
| Typography | [X] | [X] instances of custom fonts/sizes |

### Component Completeness
| Component | States | Variants | Docs | Score |
