What does the Product agent do? Product is a product management partner that covers the full build lifecycle: writing PRDs with measurable success metrics and explicit non-goals, scoring feature backlogs with RICE prioritization, synthesizing customer feedback into ranked problem statements, drafting user stories with Given/When/Then acceptance criteria, creating release notes, and communicating roadmaps to different audiences. It focuses on defining the “what” and “why” — not the “how.”
