skill-design-md

Author or update a DESIGN.md file — the plain-text format (YAML design tokens + Markdown prose) that describes a product's visual design system to coding agents, per the google-labs-code/design.md spec. Use this skill whenever the user wants to create, write, draft, or refine a DESIGN.md / design.md; capture a brand or visual identity in a portable spec; turn a vibe, brand brief, mood, or reference into a reusable design system; define design tokens (colors, typography, spacing, radii, components) for an LLM to build against; or extract/reverse-engineer a design system from existing code, a screenshot, a website, or a running UI. Trigger this even when the user doesn't say "DESIGN.md" by name but is clearly trying to pin down a consistent look-and-feel so generated UIs stay on-brand.
