# /brand-use
Switch the active brand in a multi-brand repo.
## Steps
1. **List brands** with `lib/brand.mjs` → `listBrands`. Show the current active slug
(from `brand/.active`).
2. **If a slug was given**, verify it exists under `brands/<slug>/` (or is `brand`).
If not, list the valid slugs and stop.
3. **Set active** by writing the slug to `brand/.active`.
4. **Confirm** by running `/brand-status` so the newly active kit is shown.
No network. Only reads/writes local profile files.
