Design Design System

Audit, document, or extend your design system. Use when checking for naming inconsistencies or hardcoded values across components, writing documentation for a component's variants, states, and accessibility notes, or designing a new pattern that fits the existing system.

What this skill does

Keep your interface cohesive by auditing components for inconsistencies and generating clear documentation for every variant and state. You can also design new patterns that seamlessly fit within your existing system rules. Reach for this when you need to validate your current library or expand it while maintaining a consistent look and feel.

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

## Design System Audit

### Summary
**Components reviewed:** [X] | **Issues found:** [X] | **Score:** [X/100]

### Naming Consistency
| Issue | Components | Recommendation |
|-------|------------|----------------|
| [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

- **Keyboard**: [Expected interactions]
- **Screen reader**: [Announced as...]

### Open Questions
- [Decision that needs design review]
- [Edge case to resolve]

If Connectors Available

If ~~design tool is connected:

  • Audit components directly in Figma — check naming, variants, and token usage
  • Pull component properties and layer structure for documentation

If ~~knowledge base is connected:

  • Search for existing component documentation and usage guidelines
  • Publish updated documentation to your wiki

Tips

  1. Start with an audit — Know where you are before deciding where to go.
  2. Document as you build — It’s easier to document a component while designing it.
  3. Prioritize coverage over perfection — 80% of components documented beats 100% of 10 components.
