What problem does it solve? Product managers often start building before clarifying why a product should exist, who it serves, and what the MVP must prove. This Skill turns scattered product thinking into a complete, reviewable Product Proposal with explicit evidence levels, falsifiable judgments, and a versioned decision trail. ## Core Features & Use Cases - Complete Proposal Generation: Produces a full Product Proposal covering users, problems, product mechanism, boundaries, value chain, MVP case rundown, and downstream handoff summary. - Version & Supersede Management: Creates new versions (v1, v2...) for direction changes, maintains docs/proposals/INDEX.md, and atomically syncs the stable baseline into PRODUCT.md with a machine contract. - Evidence Discipline: Separates confirmed facts, reasoned inferences, and unverified assumptions, and requires a most-dangerous premise with a falsification path. - Use Case: A solo PM starting a new AI product runs the proposal flow to decide whether the product is worth building, defines the MVP validation gate, and hands the first buildable result to the design stage. ## Quick Start Ask the assistant to run /pmai-proposal to clarify the product direction and produce a complete, reviewable Product Proposal for your project.
