What problem does it solve? Design teams struggle to communicate visual identity to coding agents in a machine-readable way. This Skill creates and validates DESIGN.md files that combine YAML design tokens with human-readable rationale, ensuring consistent UI across projects and catching accessibility issues before they ship. ## Core Features & Use Cases - Authoring: Generate complete DESIGN.md files with colors, typography, spacing, rounded corners, and component tokens using token references like {colors.primary}. - Validation: Lint files for broken token references, duplicate sections, invalid values, and WCAG contrast failures using the @google/design.md CLI. - Export: Convert DESIGN.md to Tailwind theme JSON or W3C DTCG format for direct use in build pipelines. - Use Case: A designer defines a brand palette once in DESIGN.md, lints it to confirm all button text meets WCAG AA contrast, then exports Tailwind config so every project uses identical tokens. ## Quick Start Ask the agent to create a DESIGN.md file for your brand with your preferred colors and typography, then lint it for accessibility issues.
