What it does
A sparring partner for the early stage of an idea, before you write a spec. It pushes back, asks the hard questions and stops you settling on the first answer. Claude picks a mode to match where you are. In problem exploration it asks who has the problem and what they do about it today. In idea generation it offers angles you may not have tried. In stress testing it attacks your assumptions. You can shift between modes as the talk moves along. The aim is not a document. It is a few strong options you can believe in and know how to test.
You give it
- The problem or opportunity you are exploring
- Who you think has the problem
- What you have tried or learned so far (optional)
- Constraints such as time or budget (optional)
You get

Use it when
