Use Design System

Use Design System

Load an org-level design system from ~/.claude/design-systems/<name>/ into the current project.

Steps

1. If $0 (name) is missing → Bash(ls ~/.claude/design-systems/ 2>/dev/null) and show the list, ask which one.

2. Verify the folder exists: Bash(test -d ~/.claude/design-systems/$0 && echo ok || echo missing). If missing → tell the user, list what's available, stop.

3. Read the tokens file: Read ~/.claude/design-systems/$0/tokens.json

4. Copy to project-level for faster subsequent reads:

   Bash(mkdir -p .claude)
   Bash(cp ~/.claude/design-systems/$0/tokens.json .claude/design-tokens.json)

5. If ~/.claude/design-systems/$0/preview.html exists, offer to open it for visual reference via /preview ~/.claude/design-systems/$0/preview.html — lets the user remember what the system looks like before starting work.

6. Report: "Loaded design system $0 — colors, fonts, spacing, radii written to .claude/design-tokens.json. Subsequent /make-deck, /interactive-prototype, /wireframe will use it automatically."

When to NOT use this skill

• User is extracting a new system from a codebase / screenshot / Figma → use /create-design-system instead
• User explicitly said "ignore existing, I want something fresh" → route to /create-design-system with "from scratch" mode
