Personal Claude Code skills.
Run an intensive, facilitator-led brainstorming session for product/feature or technical/architecture problems — generating breadth of options, not analysis of a single answer.
Triggers on: brainstorm / ideate / generate ideas / explore options / "run an ideation session" + a named challenge, or /ultrabrain.
Does not use for stress-testing an existing plan (use grilling), reasoning through one hard problem (use ultrathink), reviewing code (use code-review), or authoring a skill (use generate-skill).
Workflow: frame the challenge in dialogue (How Might We + success criteria + constraints) → diverge widely with zero judgment across ≥3 techniques (inversion, analogies, SCAMPER, Six Thinking Hats) → converge (cluster, score, prioritize) → synthesize a prioritized ideas document plus a concrete action plan for the chosen idea.
