SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PRD requirements are frequently scattered, ambiguous, and hard to translate into actionable design, leading to mismatches between planning and implementation.

Core Features & Use Cases

  • Expand FRs and NFRs from PRD into formal, testable requirements with acceptance criteria and traceability.
  • Generate concise user stories (Given/When/Then) aligned to major features and technical constraints.
  • Produce a complete specification document ready for downstream design and planning steps, alongside a PRD-aligned design footprint.

Quick Start

Provide the PRD in the current directory and run the /specify trigger to generate the detailed specification.

FAQPage Schema
How do I turn PRD requirements into testable specifications?

To turn PRD requirements into testable specifications, you can automate the extraction of functional and non-functional requirements, attach acceptance criteria, and generate aligned user stories. This ensures traceability and formalizes ambiguous product requirements.

How do I generate user stories from a PRD?

Generating user stories from a PRD involves extracting major features and technical constraints to produce concise Given/When/Then formats. This translates scattered product requirements into actionable development tasks aligned with architecture planning.

What is the best way to expand functional and non-functional requirements from a PRD?

The best way to expand functional and non-functional requirements from a PRD is to automate the extraction process, appending formal acceptance criteria and error handling guidance. This creates a complete specification document ready for downstream design.

Can I use a PRD to create architecture planning and design footprints?

Yes, you can use a PRD to create architecture planning and design footprints by aligning extracted requirements with technical constraints. This produces a PRD-aligned design footprint alongside a complete specification for downstream planning steps.

How do I add acceptance criteria to ambiguous product requirements?

Adding acceptance criteria to ambiguous product requirements requires formalizing them into testable specifications. By expanding functional and non-functional requirements, you attach specific criteria that ensures traceability and validates implementation against the original PRD.

Why does translating a PRD into design planning often lead to implementation mismatches?

Translating a PRD into design planning often leads to implementation mismatches because PRD requirements are frequently scattered and ambiguous. Automating the generation of detailed, testable specifications with acceptance criteria bridges this gap between planning and implementation.
