What problem does it solve? Writing a high-quality PRD requires structured discovery, honest scoping, and rigorous review. This Skill guides users through creating, updating, or validating a PRD with calibrated rigor, decision logging, 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. - Structured discovery and templates: Elicitation-based discovery, stakes calibration, user journey capture, an Essential Spine template, and an Adapt-In Menu for domain-specific sections like compliance or API contracts. - Reviewer gate and reporting: Parallel reviewer subagents produce findings that are synthesized into HTML and Markdown validation reports, with a decision log and addendum tracking every choice. - Use Case: A product manager needs a launch-grade PRD for a new consumer app feature. The Skill runs discovery, drafts the PRD with numbered FRs and user journeys, runs rubric and adversarial reviews, and finalizes the document with an assumptions index. ## Quick Start Ask the assistant to help you create a PRD for your product idea and answer its discovery questions.
