If you mostly use chatbots, this is where you can waste time: 1 boring rules file may matter more than the shiny AI canvas. ๐
I almost scrolled past this because it looked like another "AI made a screen fast" moment. The thing is, if you only stare at the demo, you can burn hours and attention chasing the wrong value.
What changed my mind was 2 very plain clues. Google says DESIGN.md is a rules file that can move between design and coding tools, which means the style guide stops being notes and starts becoming something an AI helper can reuse.[S001]
Then the second clue made it feel real, not just polished marketing. The toolkit has 2 built-in moves for that same file: bring it in, then turn it into a full visual system for colors, spacing, and style.[S003]
That is the whole before/after for me: before, this looked like 1 more flashy canvas. After, it looks like 1 reusable playbook that can travel with the project. ๐ง
Small boundary: I only checked Google's public post plus 1 toolkit source file, not a live team setup, so your mileage may vary. Save this for the next shiny AI launch, and send it to the friend who only watches the demo. Would you rather own the pretty screen, or the playbook behind it?
