Verdict
The entry skill is the reason the rest of the methodology works. Brainstorming refuses to let the agent jump into code, classifies how much process a request needs, and drives the idea through context, refinement, a chunked design, and explicit human sign-off before anything is planned or built.
Best for
New features, ambiguous product asks, and any request where the agent would otherwise choose an implementation before the problem is understood.
Keep in mind
It adds deliberate friction that is wasted on tiny, already-specified changes, and its value depends on the human actually engaging with the design chunks instead of approving them unread.
Example task
Brainstorm a team-invitations feature end to end and show me the design in reviewable chunks before writing a plan or any code.
