Design/branding for any user-facing repo becomes a vendor-neutral on-disk
contract — design/DESIGN.md (nine-section brief) + design/tokens.tokens.json
(W3C DTCG tokens) — that every agent reads before building UI. Claude Design
is the interchangeable cloud front-end, never a dependency.
- /design (main-thread command): inspiration-first scoping -> BRIEF.md -> user
drives the cloud step -> distill the export back into the contract. Phase-C
token distillation is agent-mediated because the export is inline-hardcoded
HTML/CSS, not DTCG.
- design-checker (read-only subagent): audits a repo's UI against its own
committed contract; says "run /design first" when none exists.
- /new-project scaffolds design/ for user-facing projects.
