Brainstorm

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

Triggers

• Greenfield entry ("brainstorm this", "explore options", "compare approaches", "help me think through X") → run the workflow below
• Grill entry ("pressure-test this plan", "find holes in this", "second opinion", "grill my assumptions", "considering a pivot") → run the workflow below

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

Workflow

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