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 review happens too late. This Skill guides a structured PRD workflow with persistent decision logging, calibrated rigor, and multi-reviewer validation. ## Core Features & Use Cases - Three intent modes: Create a new PRD through facilitated discovery, Update an existing PRD against a change signal, or Validate a PRD against a seven-dimension quality rubric without modifying it. - Persistent run workspace: Every decision, change, and assumption is appended to a memlog, with an addendum capturing depth that belongs downstream, so sessions can stop and resume without losing context. - Reviewer gate and synthesis: Parallel reviewer subagents critique the PRD and their findings are consolidated into an HTML and Markdown validation report with severity-tiered findings. - Use Case: A product manager needs a launch-grade PRD for a new consumer feature. The Skill runs a brain dump, calibrates stakes, drafts the PRD with tagged assumptions, runs reviewer subagents, and finalizes a polished document with an assumptions index. ## Quick Start Ask the assistant to help you create a PRD for your product idea and answer the discovery questions it asks.
