A markdown style guide your AI agent can actually read

What it does

The repository gathers DESIGN.md files—plain-text design system documents introduced by Google Stitch—for dozens of well-known brands across tech, fintech, retail, and media. Each file captures a site’s visual rules, tokens, and patterns in markdown, the format LLMs read most easily. Drop one into a project and tell an AI agent to match it, skipping the usual design-to-code translation layer.

The interesting bit

Instead of whiteboarding a design system from scratch, you copy the look and feel of companies like Stripe, Linear, or Nike. The collection treats markdown as a dumb, durable pipe between a brand’s design rules and an agent’s code generator—no Figma plugins or JSON schemas in the loop.

Key highlights

• 72 DESIGN.md files sourced from real websites, spanning AI platforms, developer tools, fintech, e-commerce, automotive, and media brands
• Covers major names including Apple, Vercel, Notion, Coinbase, and Shopify with analyzed patterns, tokens, and typographic rules
• Plain-text format meant for direct LLM consumption; no parsers, plugins, or export workflows needed
• Pairs conceptually with AGENTS.md (build instructions), positioning DESIGN.md as the strictly visual counterpart
• Maintained by VoltAgent, with a request service for missing brands and a sponsorship program

Caveats

• The visible collection consists entirely of external links to getdesign.md; the README states the repo provides the files, but the rendered page does not display the raw markdown directly
• The “Ranked #150 globally on GitHub” claim appears only in a sponsor pitch and is not independently verified

Verdict

Worth bookmarking if you are vibe-coding a landing page and want a polished, recognizable aesthetic without hiring a designer. Skip it if you already enforce a strict internal design system or prefer not to rely on externally hosted files.
