Design.MD

Design.MD solves a narrow, real problem well. AI coding agents default to a recognizable house style — soft gradients, purple accents, the same three card layouts — and the usual remedy is either hiring a designer or hand-writing a style guide. A DESIGN.md brief sitting in the repo gives the agent something concrete: named colors, type scale, spacing rhythm and the reasoning behind them. Because entries follow Google's official DESIGN.md spec, the format is portable across Claude Code, Cursor, OpenAI Codex, Gemini and ChatGPT-based assistants, so the same brief works whichever agent you switch to. The catalog's breadth is the actual product. 550+ analyses grouped by category mean you can find a close analogue fast — Stripe for fintech surfaces, Linear for dense app UI, Notion for warm editorial minimalism, BMW or Ferrari for premium dark automotive styling — and the entries are written as design-pattern analyses, with notes on accent treatment, surface and layout logic, rather than as asset dumps. The five documented workflows (style without design skills, match a reference, stay consistent, restyle, reuse one brief) map onto how people actually build with agents, and the reusable-brief pattern is the one that pays off most: one file, every new page and screen held inside the same visual language. The honest weaknesses: these are independent analyses of publicly visible design patterns, so you get inspiration, not licensed brand assets or official guidelines — do not ship a BMW-styled site and call it BMW. A brief also steers rather than enforces, so you still need to review what the agent produces. And Design.MD is not a design-system generator: there's no component code generation, no token pipeline, no drag-and-drop builder, and no strict compliance checking. Teams already running a mature Figma or Storybook system have no gap for it to fill. The private DESIGN.md service is handled manually and shared privately, with the site asking for company email and replying only to those — so treat turnaround as a request, not a checkout. Adjacent products — Website Starter Kit, Mobile App Starter Kit, Backgrounds, Video templates — exist if you want more scaffolding, but they're outside the core value.
