What problem does it solve? PRDs often reach engineering with vague requirements, hidden contradictions, missing scope decisions, and untestable acceptance logic, causing rework and delivery confusion. This Skill performs a structured final quality review of an existing PRD draft from the perspectives of product, design, engineering, QA, and operations. ## Core Features & Use Cases - Multi-dimensional review: Checks problem clarity, target users, release scope, workflows, functional and non-functional requirements, metrics, dependencies, risks, and cross-section consistency. - Failure-mode detection: Identifies common PRD problems such as untestable requirements, duplicated or conflicting requirements, vague metrics, and unresolved decisions hidden inside requirements. - Structured Russian-language report: Produces a verdict (strong / workable / weak), key ambiguities with recommended clarifications, missing decisions, prioritized edits, and a final readiness checklist. - Use Case: Before handing a PRD to engineering, paste the draft and ask for a final red-team review to surface the points where the team would still need to guess. ## Quick Start Use the prd-quality-review skill to red-team this PRD draft and tell me whether it is ready for engineering handoff.
