Brainstorm

Before you jump into implementation, run this to separate what you're building from how you'll build it. It walks you through four phases: clarifying vague goals, understanding the actual problem, generating 2-3 approaches with adversarial critique (what breaks first, what's the hidden cost), and capturing structured output that feeds into /plan. The red team questions in phase 3 are the real value here. They force you to stress test each option before committing. Outputs a dated markdown file in .agents/brainstorm/ with problem statement, approaches considered, selected approach, open questions, and a concrete next step. Think of it as enforced thinking time before you start moving fast in the wrong direction.
