Design-system fidelity is becoming measurable
Coinbase reports that Code Connect improved adherence to its design system while reducing token costs for coding agents.
average reduction in token costs reported by Coinbase when testing Code Connect with coding agents.
The Story
Coinbase’s design-system team tested Figma Code Connect as a way to give coding agents better guidance. The team says the approach improved design-system adherence and cut token costs by an average of 22.5%. ([figma.com](https://www.figma.com/blog/ai/?utm_source=openai))
That matters because the quiet failure mode of AI-assisted building is drift: a button that is almost right, a spacing value that feels close, a component recreated instead of reused. Better connections between design intent and production code make quality easier to preserve.
The takeaway for Studio Wensday is practical: document not only what a component looks like, but where it lives, when to use it and what it should never become. A visual system becomes more valuable when it can teach other tools how to protect it.

Design-system documentation is now an interface for agents.
