Summary

Google is open-sourcing DESIGN.md, a specification for exporting and importing design rules across tools and platforms, enabling AI agents to understand design intent and validate accessibility standards. The specification includes new features like a Tokens section for design tokens, an experimental Components section, and a CLI validator tool to help build a shared visual language for AI-assisted design.

Summarized by ThreadOut AI from the full thread. May miss nuance — read the thread below.

  1. #1

    Today, we’re open-sourcing the draft specification for DESIGN.md, so it can be used across any tool or platform. We’re also adding new capabilities. DESIGN.md lets you easily export and import your design rules from project to project. Instead of guessing intent, agents know exactly what a color is for and can even validate their choices against WCAG accessibility rules.

    We’ve also given DESIGN.md some new exciting capabilities: ✨ Tokens Section: A new area that keeps your design tokens and natural language descriptions living together in the exact same file. 🧩 Components Section (WIP): We are experimenting with a new section to define components, and we want your feedback! 🛠️ CLI Validator: The repo includes a CLI tool to validate your design.md file against the spec—incredibly useful when building with your own agents.
