brainstorm

Cross-agent brainstorming and idea critique for early-stage decisions, architecture options, product/workflow design, debugging hypotheses, implementation strategies, or "what are we missing?" questions. Use when the user asks to brainstorm, workshop, explore options, stress-test an idea before implementation, compare possible approaches, or get Claude/Codex perspectives on a hypothetical plan. Prefer critique for reviewing existing diffs, completed work, push readiness, or concrete artifacts.
