This is a structured interview process that stops you from building the wrong thing. It walks through eight categories (problem definition, user experience, data model, technical landscape, scale, integrations, security, operations) and won't let you skip ahead until each is properly understood. The smart bit is the research loops: when you say something vague like "I want real-time updates," it can pause to investigate WebSockets vs SSE vs polling, then come back with informed follow-up questions. It also catches conflicts early, like when you want both "simple" and "feature-rich." Probably overkill for a weekend prototype, but if you're about to commit engineering time to something, spending 20 minutes on a proper discovery interview beats spending weeks building something nobody wanted.
