What problem does it solve? Writing a PRD that is decision-ready, scoped honestly, and usable by downstream UX, architecture, and story workflows is hard; this Skill guides the process with structured discovery, templates, and multi-reviewer validation instead of producing a hollow document. ## Core Features & Use Cases - Three intent modes: Create a new PRD from a brain dump, Update an existing PRD against a change signal, or Validate a PRD with a seven-dimension quality rubric without modifying it. - Adaptive PRD structure: An Essential Spine template plus an Adapt-In Menu of section clusters (compliance, monetization, API contracts, hardware constraints) selected based on the product's actual concerns and stakes. - Reviewer gate and synthesis: Parallel reviewer subagents write findings to per-reviewer files, then a synthesis pass renders a consolidated HTML and Markdown validation report with severity-tiered findings. - Use Case: A product manager with rough notes and customer research invokes the skill, chooses the coaching path, narrates user journeys, and ends with a finalized PRD, an addendum of deferred depth, and an auditable decision memlog. ## Quick Start Ask the assistant to help you create a PRD for your product idea and answer its discovery questions about vision, users, and scope.
