Interview the user relentlessly about a plan or implementation idea until reaching shared understanding, resolving each branch of the decision tree. For existing plans, refines them. For raw ideas, builds a plan from scratch. Then stress-tests the plan through a tribunal of AI personas (Skeptic, Critic, Advocate) and produces a verdict with strengths, weaknesses, risks, and action items. Use when asked to "review my plan", "review my idea", "challenge my design", "stress test this approach", "get feedback on my plan", "flesh out this idea", or /review-idea.
