Copy the prompt, paste it into Claude, Cursor, or any coding agent, then just say what you want to build. It scaffolds the Mutual design system into your repo, tokens, all six themes, components, and the rules that keep everything on-brand and accessible, then builds whatever you ask using only that system.
Design System · One source · engineers & AI agents build from it
This is a real, shipping design system for two products, Mutual, Ark, and a third concept, ToNite, generated from a single semantic token layer that exports cleanly to Swift and React.
Every color, type ramp, and component below is rendered live from those tokens. Flip the brand and mode switches up top, the entire page re-themes from one source of truth. The point isn't that it's pretty. It's that it's structured: a new engineer, or an AI agent, can read these tokens and assemble correct, on-brand, accessible UI without me in the loop. Hit AI view to see exactly what they build from.
