What Design System does

The Design System skill is a comprehensive tool for managing and enhancing your design system. It enables users to perform audits for consistency, document components thoroughly, and design new patterns that align with existing systems. This skill is particularly useful for teams looking to maintain a cohesive visual language and ensure that all components adhere to defined standards.

With the ability to conduct a full system audit, users can identify naming inconsistencies, hardcoded values, and component completeness. The audit output provides a detailed summary, highlighting issues found and offering recommendations for improvement. This structured approach ensures that design tokens, components, and patterns are consistently applied across the system, fostering a unified user experience.

The documentation feature allows users to create detailed records for each component, including its variants, states, properties, and accessibility considerations. This is essential for maintaining clear communication within teams and ensuring that all members understand the intended use of each component. The skill also facilitates the extension of the design system by allowing users to propose new components or patterns, ensuring that the system evolves to meet new design challenges.

Overall, the Design System skill is ideal for designers and developers who want to streamline their design processes, maintain high standards of quality, and ensure that their design systems are well-documented and adaptable to future needs.

When to use it

Use this skill when you need to audit your design system for consistency, document components, or create new design patterns.

When not to use it

This skill may not be suitable for teams that do not have a structured design system or are looking for a tool that offers visual design capabilities.

What you can build with it

Conducting a System Audit

Use the audit command to evaluate your design system for inconsistencies and hardcoded values before a major release.

Documenting Component Variants

Utilize the document command to create comprehensive documentation for a new button component, detailing its states and accessibility.

Extending the Design System

Employ the extend command to propose a new form component that addresses gaps in your current design patterns.

How to install Design System

View source

1. Install with the skills CLI

npx skills add anthropics/knowledge-work-plugins/design-system --agent claude-code

2. Or install it manually

Download the skill folder and drop it into ~/.claude/skills/ for all projects, or .claude/skills/ to scope it to one repo. Restart Claude Code so it picks up the new skill.

Anthropic's agentic coding CLI, and the reference implementation of Agent Skills. Drop a skill folder into ~/.claude/skills and Claude Code loads it automatically whenever a task matches the skill's description. Claude Code docs

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

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.
