What problem does it solve? Writing a PRD from scratch is hard: requirements end up vague, unmeasurable, or missing domain compliance needs, which causes rework in UX, architecture, and development. This Skill guides a structured, step-by-step workflow that produces a dense, traceable PRD optimized for both human stakeholders and downstream AI agents. ## Core Features & Use Cases - Guided 13-Step Workflow: Sequentially covers initialization, project classification, vision, executive summary, success criteria, user journeys, domain requirements, innovation, project-type specifics, scoping, and functional/non-functional requirements. - State Tracking & Resumption: Tracks progress in document frontmatter (stepsCompleted) so an interrupted PRD session can be resumed exactly where it left off. - Quality Enforcement: Applies SMART criteria, anti-pattern elimination (vague adjectives, implementation leakage), and domain-specific compliance checks (HIPAA, PCI-DSS, GDPR) via classification CSVs. - Use Case: A product manager says "let's create a PRD for our new SaaS feature" and is walked through discovery, journey mapping, and measurable FR/NFR definition, producing a complete prd.md ready to feed UX design and architecture workflows. ## Quick Start Ask the assistant to create a new product requirements document from scratch and follow the guided step-by-step workflow.
