Cradle Design System
Cradle's visual language — a modern, physics-native desktop AI environment.
Between Linear and Vercel: precise, high-contrast, unsentimental.
Step 1 · Identify the task
| User says | Task tier | Read |
|---|
| "make a mockup for X" | New mockup | CHEATSHEET.md + references/tokens.md + references/anti-patterns.md |
| "build component X" | New React component | CHEATSHEET.md + references/components.md + references/anti-patterns.md |
| "convert this mockup to React" | Handoff | references/mockup-to-react.md + references/components.md |
| "audit this file for token compliance" | Token audit | references/anti-patterns.md + references/tokens.md |
| "add animation to X" | Motion | CHEATSHEET.md (Animation section) |
| "review this design" | Review | CHEATSHEET.md + references/anti-patterns.md |
Step 2 · Produce
- For mockups: start from
templates/scaffold.html, drop in snippets from templates/snippets/
- For React components: import from
apps/web/src/components/ui/, style with cn() + static Tailwind classes
- For tokens: all color vars in
src/tokens.css; all design rules in references/tokens.md
Step 3 · Verify
Run before shipping:
pnpm check
If check fails, fix the source (src/tokens.css or template), never the artifact.
When NOT to use this skill
- Backend, API, or server-side code
- Database schema or migration tasks
- Non-UI TypeScript utilities
