A curated collection of ready-to-use DESIGN.md files — plain-markdown design system documents reverse-engineered from real companies' websites — that AI coding agents read to generate UI consistent with a given brand's visual language. Each entry analyzes a brand's color, typography, and layout patterns into a drop-in markdown spec.
A curated collection of reusable "skills" (structured prompt/instruction modules) for AI coding agents like Claude Code, Cursor, Codex CLI, and Gemini CLI. It packages templates, bundles, and workflows that extend agent capabilities, along with quality and security guidelines for contributors.
A file-format specification and CLI/library from Google Labs for describing a design system to coding agents. A DESIGN.md combines machine-readable design tokens (YAML front matter) with human-readable rationale (markdown prose), and the tooling lints, diffs, and exports those tokens to formats like Tailwind and W3C DTCG.
