Use when turning a fuzzy idea into a refined design through dialogue — across software, writing, talks, events, naming, activities, or any creative/design task. Its adversarial lenses also stress-test a plan or proposal already on the table. Triggers: 'brainstorm', 'help me think about/through', 'figure out', 'work through', 'I have this idea', 'let's design', 'flesh this out'. Domain-agnostic. Not for: open-ended ideation with no anchor ('what should I build?'), implementing from a finalized spec, narrow binary decisions ('X or Y?'), retrospective review, mechanical refactors, or reframing whether the presenting question is the "real" one.
