The anatomy of DESIGN.md
DESIGN.md is a markdown-based design skill file format that provides AI models with brand guidelines, style foundations, and accessibility rules to generate UI code. Instead of complex Figma-based design systems, a concise human-readable markdown file gives LLMs enough context to build interfaces. TypeUI offers a CLI to install these skill files into AI agent folders (Claude, Codex, Google Stitch), plus Figma and Penpot plugins to generate skill files from existing designs. The author argues this approach replaces the traditional designer-to-developer Figma workflow, with AI fully delegating UI creation under human coordination.
