hue
Agent skill that turns any brand URL or screenshot into a design system
hue is an MIT-licensed skill for Claude Code and Codex that reads a brand from a URL, a name, or a screenshot and writes out a complete design language as a second, generated skill: color tokens, typography, spacing, light and dark mode, hero-stage recipes, icon-kit selection, and a component library. You clone it into ~/.claude/skills or ~/.agents/skills once, then say 'make a design skill from cursor.com' in any session. Every generated skill is gated through scripts/validate.mjs, which checks YAML syntax, orphan CSS selectors, undefined var(--token) usages, leftover placeholders, em-dashes, the SKILL.md frontmatter contract, WCAG contrast on core text/background pairs, and AI-default display fonts. Seventeen worked examples ship in examples/, each with design-model.yaml and landing-page.html.
git clone https://github.com/dominikmartn/hue ~/.claude/skills/hueReach for hue when the target brand is NOT in awesome-design-md's 73 and you need a system invented from a URL or screenshot - it is a generator, where DESIGN.md collections are a lookup. Install path matters: ~/.claude/skills/hue for Claude Code, ~/.agents/skills/hue (or $CODEX_HOME/skills/hue) for Codex, and after generating always run `node scripts/validate.mjs <generated-skill-folder>` because it exits 1 on undefined var(--token) usages and failed WCAG contrast, which is the single most common way a generated system silently breaks. It composes cleanly with Impeccable - hue defines the identity, Impeccable enforces craft - but note the output is vanilla CSS custom properties and HTML, not React or Tailwind, so you translate before dropping it into a component framework.
Why it is here. Most design-for-agents tooling hands you a fixed style; hue is one of the few that derives a validated, self-consistent system from an arbitrary brand and then hard-fails on its own mistakes.
