SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill bridges the gap between a Product Requirements Document (PRD) and a detailed functional design, ensuring that "what to build" is clearly translated into "how to build it."

Core Features & Use Cases

  • Automated Design Generation: Creates comprehensive functional design documents based on existing PRDs.
  • Structured Output: Generates key sections like system architecture, data models, component designs, and algorithms.
  • Use Case: After defining product requirements in docs/prd.md, use this Skill to automatically generate a detailed docs/functional-design.md that engineers can use for implementation.

Quick Start

Use the functional-design-creator skill to generate a functional design document from the PRD.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert a PRD into a functional design document?

To convert a PRD into a functional design document, you need an existing 'docs/prd.md' file. The skill translates product requirements into system architecture, data models, and component designs, outputting a structured 'docs/functional-design.md'.

What is functional design in software engineering?

Functional design in software engineering translates the 'what to build' from a Product Requirements Document into 'how to build it'. It details system architecture, data models, component designs, and algorithms for engineers to implement.

What sections are included in a generated technical specification?

A generated technical specification includes structured sections for system architecture, data models, component designs, and algorithms. It references templates and guides to ensure comprehensive functional design documentation.

Do I need an existing product requirements document to generate system architecture?

Yes, you need an existing product requirements document located at 'docs/prd.md' to generate system architecture. The functional design creation process depends entirely on parsing this input file to detail components and data models.

Can I automatically generate component designs from markdown requirements?

Yes, you can automatically generate component designs from markdown requirements. By processing your 'docs/prd.md' file, the skill creates a detailed 'docs/functional-design.md' covering algorithms and system architecture without manual formatting.

What is the best way to document software architecture for engineers?

The best way to document software architecture for engineers is to generate a functional design document from your PRD. This bridges product requirements and implementation by detailing data models, algorithms, and component designs in a structured markdown file.
