This is the triage layer for fuzzy ideas before they become features or roadmaps. It routes you to the right next step based on four cases: already clear enough (skip straight to design), single feature that needs exploration (writes a feature brainstorm), multi-feature ready to decompose (hands off to roadmap), or multi-feature that needs grilling first (saves to the open brainstorm space). The skill treats AI as a thinking partner, not a scribe. It will challenge your initial solution, ask what problem you're actually solving, and offer counterintuitive alternatives. Crucially, it knows when to stop talking and won't force brainstorming on ideas that are already baked.
