Design.md

DESIGN.md files that describe a brand's colors, type, spacing and components, so your coding agent can work in that style. We wrote them ourselves; the brands did not.

Linear

Productivity

Dark-first, keyboard-driven product UI with crisp Inter type, low-contrast chrome and a restrained indigo accent.

Notion

Productivity

Document-first minimalism: warm off-black text, almost no chrome, and content blocks that do the layout.

Slack

Productivity

Work chat with an aubergine sidebar, a four-color brand and clear, friendly hierarchy.
