# Design System Builder
A step-by-step workflow for building a complete design system from scratch. Integrates Supa Palette, Typescale, and Figma MCP to produce a production-ready token architecture.
**Core principles (AI-readiness):**
1. **Design decisions are infrastructure.** Every decision — a color choice, a tradeoff, a usage restriction — must find its way into the spec file that AI tools read. A decision that lives only in a chat log or a human-facing doc does not exist as far as AI is concerned.
2. **Closed set.** When AI generates UI, it picks from named tokens only. It never invents plausible-looking hex or px values.
3. **Text beats screenshots.** Pass values as text (hex codes, CSS output). Screenshots are for visual confirmation only. Making AI decode numbers from an image is both more expensive and less accurate.
4. **Verifiable.** Ship an audit script so hard-coded values are caught by a machine, not by eye.
