Store your design system in a file AI agents can read
DESIGN.md is an open-source file format that stores design tokens, color intent, and accessibility rules in plain language. AI agents read it directly, so they apply your design system correctly across any tool. For designers and developers building with AI.
Design systems don't travel. Every new tool, every new project, agents start from zero with no memory of your visual rules. DESIGN.md changes that.
What it is: an open-source file format spec from Google Labs that encodes your design system in a portable markdown file any AI agent can read directly.
Problem to solution: AI design and coding agents have no persistent understanding of your tokens, color intent, or accessibility constraints. You either re-prompt every session or accept outputs that quietly break your system. DESIGN.md gives agents a single file to reference instead of guessing.
What makes it different: unlike proprietary design system formats locked to one tool, DESIGN.md is platform-agnostic and open-source. Agents validate their choices against WCAG accessibility rules automatically, not as an afterthought.
Key features:
Tokens Section stores design tokens and natural language descriptions together in one file
CLI Validator checks your DESIGN.md against the spec before agents use it
Components Section (WIP) is an early experiment in defining reusable components inside the file
Benefits:
Design intent travels with your project across tools without re-prompting
Accessibility validation happens at the spec level, not after generation
One source of truth your entire AI toolchain can reference
Who it's for: frontend developers and product designers using AI coding or design tools who need their visual system respected across projects and platforms.
If this spec gets broad adoption, every AI design tool either speaks DESIGN.md or explains why it doesn't. That's the right kind of infrastructure bet.
