Thanks for the ping! I shipped an MCP tool called "audit-my-design-system", see state-of-ai-in-design-systems.netlify.app/ai and it works really well! Also see this prior art for your poc: github.com/sanity-labs/... github.com/christophhde...

(the study ships with its own MCP server: point your assistant at it and it can read the whole corpus, compare your design system to the state of the art, and draft a roadmap)

It's a great complement to the @designtokens.org spec, especially for the "meta of design tokens", as in: explaining how a set of tokens is structured and works (spacing system, typography scales...)! Thank you PJ for the amazing work!

I didn't want to share this yet because it's still so rough, but given new specs are starting to show up, I thought I'd throw my hat in the ring: designsystemdocspec.org I'm working on a standard schema for design system documentation. I've been using it for my own work. It doesn't suck.

I built an agentic pipeline that takes a Figma file and hands back a production-ready React component in a couple of hours. Output is design-system-team-grade. In a few spots I think the pipeline made better calls than I would have! www.kaelig.fr/design-syste...

A few years ago I designed the original logo for @designtokens.org. Recently they asked me to refresh it: simpler, more versatile, and blue (the original color of links). The new logo builds on the old one, keeping the connected core while refining it for any size or use.

I love design systems, but phew, design tokens used to *really* intimidate me. They vary by team and get complex fast! But after two years of working closely with engineers, I now see them as one of the best tools we have for bridging the gap between design & code and bringing teams together. 🎨🧑‍💻
