What problem does it solve? Turning raw product notes into a structured Product Requirements Document is slow and error-prone, and hand-written PRDs often drift from the schema that downstream planning tools expect. This Skill converts shape-notes.md (or pasted raw notes) into a schema-locked prd.md, routing every gap to an Open Questions section instead of inventing content. ## Core Features & Use Cases - Automatic context routing: Detects greenfield vs brownfield from the input's context_type frontmatter or from cwd signals (git history, lockfiles, manifests), then emits the correct 10- or 11-section template. - Thin-input heuristic: Scores the input on a 0-4 signal checklist (checkpoint block, FR-NNN requirements, Given/When/Then stories, one-sentence business rule) and warns before generating a hollow PRD. - Schema self-review and leak lint: Validates section order, frontmatter keys, and scans for technical leak (vendor names, schema notation, transport protocols) before any disk write, aborting on drift. - Collision-safe writes: Offers versioned saves (prd-vN.md) instead of overwriting an existing prd.md. - Use Case: After running /10x-shape on a new product idea, invoke this Skill to produce context/foundation/prd.md with all unresolved decisions collected in Open Questions, ready for the tech-stack selection step. ## Quick Start Ask the assistant to generate the PRD from context/foundation/shape-notes.md using the 10x-prd skill.
