Brainstorm

Structured idea exploration from vague to direction, in two entries — greenfield from a blank problem space, plan from an existing idea or plan.

Triggers

• Greenfield entry ("brainstorm this", "explore options", "compare approaches", "help me think through X") → run the workflow below
• Plan entry ("second opinion", "considering a pivot", "reconsider this direction") → run the workflow below

The deep argument (/brainstorm deep) widens the challenge on either entry — every assumption instead of the key one.

Workflow

trigger → detect entry → discover → diverge → converge → challenge → capture
