Apply a go / needs-clarification / kill gate and hand survivors off into Spec-Driven Development
Define the problem: who is affected, what hurts, goals, non-goals, and success metrics
Capture and normalize a raw idea (text, URL, ticket, or codebase pointer) into an intake note
Gather evidence — users, market, prior art, and data — to support or challenge the idea
Shape a concept: solution options, scope, appetite, and trade-offs (no implementation design)
