StitchOne file briefs the agent.
AI can draw a button. It cannot invent your decisions: which spacing step you use, what your error state is called, how your brand maps onto Material roles. The Core Skill writes those decisions down where an agent can read them.
Download the Core Skill.
One free instruction file. It names the layers, the naming logic and the rules of the system.
Add it to your agent.
Claude, Cursor or any tool that reads instructions. One paste, no plugin, no setup call.
Ask for screens.
The agent picks action/primary instead of guessing a hex, because the file tells it which token that is.
Ship what you designed.
The same W3C DTCG source generates SwiftUI, Compose, Flutter and CSS, so the build reads the values you set.
Agents do not need a bigger library. They need one that explains itself.
That is what a system is: the context layer where your decisions are written down. The kit era optimized for volume. The agent era rewards structure.
