Forces Claude to use design tokens instead of hard-coded values when building UI, which is honestly the main battle in keeping a design system consistent. Ships with spacing, color, and typography tokens plus wrappers around Box, Stack, Text, Button, Input, and Card components. The anti-patterns section is actually useful because it shows the exact mistakes Claude tends to make, like reaching for raw View components or inline styles. If you're working on a React Native codebase with an established design system, this keeps Claude from inventing magic numbers and breaking your visual consistency every time it touches a component.
