    Deliberate

    4-round brainstorming with inversion thinking

    3 adapters

    About

    The default brainstorming ceremony. Four rounds — initial positions, build and challenge, inversion (how would this fail?), and synthesis with commitments. The magic happens in rounds 3-4 after obvious ideas are exhausted.

    Capabilities

    • 4-round structure: initial → build → inversion → synthesis
    • Blind initial ideation (no groupthink)
    • Mandatory cross-referencing in later rounds
    • Inversion thinking to surface blind spots
    • Commitment extraction in synthesis round
