What problem does it solve? Writing a PRD that downstream teams can actually build from is hard: requirements end up vague, assumptions go unrecorded, and reviews happen too late. This Skill guides the full PRD lifecycle—creation, updating, and validation—with structured discovery, a persistent decision log, and multi-reviewer quality gates. ## 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. - Guided discovery with working modes: Choose a Fast path (batched questions, tagged assumptions) or Coaching path (Vision + Features or Journey-led entry points) calibrated to project stakes. - Auditable workflow: Every decision, change, and override is appended to a memlog; reviewer subagents write findings to per-reviewer files synthesized into HTML and Markdown validation reports. - Use Case: A product manager needs a launch-grade PRD for a new consumer app. The Skill elicits user journeys with named protagonists, drafts grouped features with globally numbered FRs, runs rubric and adversarial reviewers, and finalizes a polished prd.md plus addendum. ## Quick Start Ask the assistant to help you create a PRD for your product idea and answer the discovery questions it asks.
