SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides a raw product idea through a structured three-stage specification pipeline (blueprint, requirements, architecture), ensuring a durable, testable design before development.

Core Features & Use Cases

  • Stage 1 — Blueprint: synthesize a credible strategy and MVP boundary, producing a design.md.
  • Stage 2 — Requirements: convert the blueprint into testable user stories and acceptance criteria, producing requirements.md.
  • Stage 3 — Architecture: translate approved requirements into an implementation plan and architecture document, producing architecture.md.
  • Pipeline discipline: enforce not skipping stages and provide clear inputs for the next phase.

Quick Start

Submit a raw product idea to generate the blueprint, PRD, and architecture artifacts.

FAQPage Schema
How do I generate a product blueprint and architecture from a raw idea?▼

To generate a product specification from a raw idea, submit your concept to trigger a three-stage pipeline that outputs design, requirements, and implementation documents sequentially.

What is the process for creating testable user stories from an early-stage product concept?▼

Creating testable user stories from a product concept involves passing a synthesized MVP blueprint into a requirements stage that converts strategy into testable acceptance criteria.

Can I skip the blueprint stage and generate architecture directly for a greenfield project?▼

No, you cannot skip the blueprint stage to generate architecture directly, because the specification pipeline enforces staged outputs and guards against bypassing the initial strategy and requirements phases.

Do I need an existing PRD to start building an implementation plan and system architecture?▼

No, you do not need an existing PRD to start building an implementation plan, because the pipeline synthesizes a credible strategy and MVP boundary from a raw product idea before translating it into architecture.

What are the limitations of using a structured specification pipeline for greenfield products?▼

The main limitation of using a structured specification pipeline for greenfield products is the enforced staged outputs that prevent skipping phases, requiring complete blueprint and requirements validation before architecture generation.
