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.

Frequently Asked Questions about functional-design-creator

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.
