opencoo-design

name	opencoo-design
description	Use this skill to generate well-branded interfaces and assets for opencoo, either for production or throwaway prototypes/mocks/etc. Contains essential design guidelines, colors, type, fonts, assets, and UI kit components for prototyping.
user-invocable	true

Read the README.md file within this skill, and explore the other available files.

If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out of assets/ and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand.

If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.

Key non-negotiables:

• Product name is always lowercase opencoo — never OpenCoo, OpenCOO, or Open Coo.
• Warm paper (#F6F3EC) + ink (#121210) base. Advisory Amber only on agent surfaces (<10% coverage). Wiki Teal only on citations.
• Three type families, one job each: Instrument Serif italic (display only), Geist (UI), JetBrains Mono (paths/data/micro).
• No gradients. No emoji. No drop shadows for elevation. Never pill-shaped buttons.
• The logo's three glyphs (open arc / filled disc / ring-with-dot) are the entire iconography system.
