{"name":"domain-suggest","description":"Suggests short brandable domain candidates for a concept and verifies which are actually available. An AI model brainstorms N candidates fitting a concept + tone, then checks TLD availability across up to 6 TLDs via in-process domain-availability lookups.

Pair with brand-clearance (Prooflayer) on the shortlist for trademark + Wikipedia + HN signal before adopting.
