dominikmartn/hue — reverse-engineered prompt

Build me an open source AI coding skill called hue. I want it to learn a brand from a website URL, a brand name, or a screenshot, then turn that into a complete design system that Claude Code or Codex can use whenever it builds UI for me.

The skill should guide the assistant through analyzing the brand, then produce a clear design language with colors, typography, spacing, components, light and dark modes, hero section ideas, and icon style choices. The important part is consistency, so if I use the skill in different sessions, the UI still feels like the same brand.

Please include simple install instructions for Claude Code and Codex, a readable skill file, docs, and a set of example brands that show the kind of output it creates. Each example should include a design model and a rendered landing page I can open in the browser to see the result.
