Google has released DESIGN.md, an open-source file format that encodes design tokens, accessibility rules, and system details so any AI can understand and apply your design system out of the box. It validates decisions against WCAG and lets you import and export rules across projects and platforms, directly challenging Anthropic’s closed Claude Design limits.

Google has published the draft specification for DESIGN.md, letting Stitch export and import design rules across projects. This shared format lets AI agents identify color roles and check choices against WCAG accessibility standards.

A Lobste.rs thread where developers share untested ideas—from building GUI toolkits with an accessibility-first architecture to enable better testing and scripting, to using 32-bit pointers on 64-bit systems for memory savings, and applying property-based approaches to infrastructure. Contributors discuss tools like AccessKit, the x32 ABI, and the benefits of driving design by fundamental properties rather than legacy constraints.
