HOW AI-READY IS YOUR DESIGN SYSTEM? NOW YOU CAN MEASURE IT.

Summary from the TLDR Design newsletter

open-design-system-bench is an open benchmark measuring whether AI coding agents use a design system correctly when generating UI. Four systems scored between 52.2 and 63.4 on its AI-readiness composite, and none reached the AI-native tier. Across 898 graded generations, some models ignored the design system entirely while others hallucinated component names.
