This turns product asks into implementation-ready capability plans before multi-service work starts. You give it a PRD, roadmap item, or founder note, and it extracts the constraints, invariants, interfaces, and open questions that usually live only in senior engineer memory. The output is an SRS-style contract with actors, states, data implications, and explicit non-goals. Use it when product intent is clear but the architecture and policy implications are still fuzzy, or when a feature crosses repos and you need a durable artifact before code review. It won't invent product truth. It will tell you what's fixed, what's preference, and what still needs clarification.
