Contents of a design system
A generated design system includes:- Tokens — named values (colors, spacing, radii) the rest of the system references
- Colors — the palette with roles (primary, surface, accent…)
- Typography — families, sizes, weights
- Example components — 2–3 built components showing the system in use
- Logos and brand assets — included when you provide them clearly

How it’s stored
A generated system lives in your project as a living style guide: tokens intokens.json feed the CSS variables (e.g. src/index.css) that your components consume. DESIGN.md is the document representation — readable by you, usable by Agent.
Using DESIGN.md as a source
An existingDESIGN.md can seed a new design system: point at it when creating one, alongside other sources like a Figma URL, a website, code, or reference images.
