| description | Map this token system to or from any external design system (Material Design 3, Apple HIG, Fluent, Carbon, Ant, shadcn/ui, Radix, Chakra, Mantine, Bootstrap…) — adopt their look, build on their stack, or migrate between systems. Use when the user mentions interop, migration, or a specific design-system/component-library bridge. |
Skill: Migrate / Interop Design System
Bridge to or from external design systems via a role-based crosswalk.
Steps
- Read
design-systems/interop-protocol.md (Crosswalk Method, the three directions, headless-vs-styled guidance, verification).
- Use the curated tables in
design-systems/crosswalk.md for Material 3 / Apple HIG / Fluent 2 / Carbon / shadcn/ui / Radix. For others, derive a mapping with the Crosswalk Method (map by role/intent across 6 axes: color roles, type scale, spacing unit, radius, elevation, motion).
- Choose the direction:
- FROM external → our tokens (adopt their look): re-point
semantic.*.
- TO external stack (our components on their foundation): theme their primitives with our tokens.
- Migrate: Audit → Map → Bridge (alias layer) → Verify, screen by screen.
- Verify every mapped color pair for contrast (
scripts/contrast.py / a11y-audit); confirm all 8 states + dark mode survive the mapping.
Output
A crosswalk table (our token → their token → value note), a bridge plan if migrating, and verified token overrides. Render via design-code.
