the-3md-concept

Produce a three-document decision package — evidence base, smallest falsifiable build plan, expansion catalogue — from research already done or about to be done. Use this whenever someone wants to go from "should we build X / how would we build X" to something actionable — feasibility studies, build-vs-buy decisions, PoC planning, tool or vendor evaluations, greenfield repo concepts, "turn this research into a plan", "what would a minimal version look like", "give me a roadmap for this". Also use it when a conversation has produced a lot of findings and the user asks to write them up, and when auditing an existing set of concept documents for evidence discipline. Reach for it even when the user only asks for one of the three documents, because the value comes from the separation and the citation direction between them. Do NOT use it for the research itself (pair it with a research skill), for implementation work, or for a single short answer.
