# Design systems become executable agent context

## What is becoming executable

A component name is not enough to reproduce a product's design character. An
agent also needs typography, spacing, color, layout constraints, preferred
composition, anti-patterns, reference screens, and a way to inspect the result.
ProtoDash, Refero, shadcn registries, Stitch skills, and Taste Lab package more
of that environment into machine-usable form.

## Supporting evidence

- ProtoDash combines Stripe's design system with rules, components, sandboxes,
  and in-product review.
- Refero exports visual references as structured DESIGN.md files.
- shadcn registries make components and installation metadata discoverable.
- Stitch and Taste Lab preserve design intent as reusable agent context.

## Operational consequence

Version design rules next to components, include representative states and
counterexamples, and require browser screenshots at target viewports. The
agent can assemble the interface, but rendered evidence remains the acceptance
artifact.
