What problem does it solve? Writing a PRD that downstream teams can actually build from is hard: requirements end up vague, assumptions go untracked, and reviews happen too late. This Skill guides the full PRD lifecycle with structured discovery, a quality rubric, and an auditable decision log. ## 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 a Coaching path (Vision + Features or Journey-led entry points) calibrated to project stakes. - Reviewer gate and validation reports: Parallel reviewer subagents score the PRD and produce consolidated HTML and Markdown validation reports with severity-tiered findings. - Use Case: A product manager describes a new consumer app idea in plain language; the Skill elicits user journeys with named protagonists, drafts a PRD with numbered FRs and success metrics, runs adversarial reviewers, and finalizes a decision-ready document. ## Quick Start Ask the assistant to help you create a PRD for your product idea and answer its discovery questions.
