What problem does it solve? Turning a raw product idea or a proposed change to an existing system into a well-structured PRD is hard: ideas arrive vague, scope creeps, and critical decisions go unrecorded. This Skill runs a guided, six-phase discovery conversation that captures vision, personas, access control, MVP scope, functional requirements, and business logic into a resumable shape-notes.md file that feeds directly into PRD generation. ## Core Features & Use Cases - Greenfield/brownfield auto-detection: Scans the working directory for git history, lockfiles, and manifests to detect whether you are starting from scratch or changing an existing system, then adapts all discovery phases accordingly. - Structured six-phase discovery: Walks through vision and problem, persona and access control, MVP discipline, functional requirements with a Socrates challenge round per FR, business logic with empty-CRUD anti-pattern detection, and quality cross-checks. - Checkpointed resume: Writes a checkpoint block into shape-notes.md frontmatter so interrupted sessions can resume from the exact phase where they left off. - Use Case: You have an idea for a recipe app that suggests meals from fridge contents. Invoke the skill with the idea inline, answer the facilitated questions phase by phase, and receive a complete shape-notes.md ready for /10x-prd to convert into a schema-conforming PRD. ## Quick Start Invoke the skill with your idea inline, for example "/10x-shape a recipe app that suggests meals from what's in your fridge", and answer the guided discovery questions.
