SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quick ideation for product ideas by turning fuzzy scenarios into a concrete, editable draft PRD sketch, saved as a scratch artifact and never committed to history.

Core Features & Use Cases

  • One-shot generation of a spec sketch from a scenario, written to .claude/specs/<slug>/spec.md
  • Includes a mermaid diagram to visualize the envisioned flow
  • Designed to be edited locally and then passed via /ship-spec --plan <path> to the existing formalization pipeline
  • Works with the slug derivation rules used by the /prd skill to ensure consistent naming

Quick Start

Provide a fuzzy scenario as input and let the tool generate a draft PRD sketch at .claude/specs/<slug>/spec.md

FAQPage Schema
How do I generate a draft PRD from a fuzzy product scenario?

To generate a draft PRD from a fuzzy product scenario, provide your scenario text to the imagine skill. It writes an editable spec sketch with a mermaid diagram to .claude/specs/<slug>/spec.md for immediate product-management use.

What is the best way to sketch out product requirements before formalizing a spec?

Sketching product requirements before formalizing a spec is best handled by turning fuzzy ideas into a tangible artifact. The tool outputs a draft PRD sketch locally, ensuring your ideation phase remains a scratch file that is never committed to history.

Can I use the generated spec sketch with the ship-spec planning flow?

Yes, you can use the generated spec sketch with the ship-spec planning flow. After editing your draft locally, pass the file path via the /ship-spec --plan command to transition your sketch into the formalization pipeline.

Does the generated PRD sketch include visual diagrams for workflow mapping?

Yes, the generated PRD sketch includes visual diagrams for workflow mapping. Each output spec.md file contains a mermaid diagram designed to help you visualize the envisioned product flow alongside the written requirements.

How are spec files named and structured in the local directory?

Spec files are named and structured using slug derivation rules to ensure consistent naming across your product-management workflow. The draft PRD sketch is written directly to the .claude/specs/<slug>/spec.md directory path.

When should I avoid using an automated PRD draft generator?

You should avoid using an automated PRD draft generator when your requirements are already formalized or if you need a committed historical record. This tool targets quick ideation, producing scratch artifacts designed to be heavily edited before formal planning.
