an open-source skill that learns any brand from a url, name, or screenshot and turns it into a complete design system. works on claude code and codex. install it once, and every component your ai assistant builds after that matches your brand.

see it in action: hueapp.io

a full design language as an ai coding skill — color tokens, typography, spacing, components, light + dark mode, hero stage recipes, icon kit selection. opinionated enough that two different sessions using the generated skill produce visually consistent output.

git clone https://github.com/dominikmartn/hue ~/.claude/skills/hue

git clone https://github.com/dominikmartn/hue ~/.agents/skills/hue

alternative codex path (cli installer compatible):

git clone https://github.com/dominikmartn/hue "${CODEX_HOME:-$HOME/.codex}/skills/hue"

then in any session say something like:

• "make a design skill from cursor.com"
• "create a design language inspired by raycast"
• "generate a hue skill from this screenshot"

the assistant picks up the trigger and walks through the analysis.

every generated skill gets gated through scripts/validate.mjs before it ships:

node scripts/validate.mjs <path-to-generated-skill-folder>

it checks yaml syntax, orphan css selectors, undefined var(--token) usages, leftover placeholders, em-dashes, the SKILL.md frontmatter contract, wcag contrast on the core text/background pairs, and ai-default display fonts. exit code 1 on any error.

seventeen brands live in examples/ showing the range of output hue produces. sixteen are fictional one-shots, one is real (meadow ↦ the mymind-design skill).

each has a design-model.yaml + landing-page.html. ridge and stint also ship an app-screen.html. halcyon ships a full component-library.html. open them in a browser to see the system rendered.
