What problem does it solve? Writing a high-quality PRD requires structured elicitation, scope discipline, and rigorous review — most teams either skip discovery or produce template-filler documents. This Skill coaches users through creating, updating, or validating PRDs with calibrated rigor, persistent 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. - Adaptive structure: An Essential Spine template plus an Adapt-In Menu of conditional sections (compliance, monetization, API contracts, hardware constraints) matched to the product's actual concerns. - Audit trail and resume: Every decision, change, and assumption is appended to a memlog so runs can stop and resume without losing context; headless mode returns structured JSON status for automation. - Reviewer gate: Parallel subagent reviews write findings to files and synthesize into HTML and Markdown validation reports with severity-tiered findings. - Use Case: A product manager with rough notes and customer research asks for a PRD; the Skill runs discovery, drafts FRs/UJs/SMs with stable IDs, runs reviewer subagents, and finalizes a polished prd.md plus addendum. ## Quick Start Ask the assistant to help you create a PRD for your product idea, providing any existing briefs or research documents you have.
