Use when the user wants help shaping an idea through conversation: generating options, choosing between options, stress-testing assumptions, or turning an early idea into a lightweight spec. Also use when explicitly asked to run the ideation pipeline from messy input into contract, PRD, and implementation spec artifacts. Trigger on "ideate", "explore this idea", "poke holes in this", "help me choose", "turn this into a PRD/spec", or /ideation. Do not use for merely capturing an idea, processing inbox notes, or building the MVP directly.
