SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill transforms complex technical concepts into clear, maintainable diagrams that can be version-controlled alongside your code, eliminating the need for manual drawing tools.

Core Features & Use Cases

Diagram Generation: Create 9 types of diagrams (Class, Sequence, Flowchart, ERD, C4, State, Git, Gantt, Pie/Bar) from simple text.
Version Control Friendly: Diagrams are text-based, making them easy to update, review in pull requests, and store with code.
Use Case: Document your system's architecture using a C4 diagram or model your database schema with an ERD, all within your documentation files.

Quick Start

Generate a sequence diagram showing a user login flow.

FAQPage Schema

How do I generate architecture diagrams from text for version control?▼

You generate version-controllable architecture diagrams by writing text-based syntax that renders into C4 diagrams, flowcharts, and class diagrams. This approach stores diagrams as text files alongside your code, eliminating manual drawing tools and enabling pull request reviews.

What diagram types can I create using Mermaid syntax?▼

Mermaid syntax supports generating nine diagram types: class diagrams, sequence diagrams, flowcharts, ERDs, C4 diagrams, state diagrams, Git graphs, Gantt charts, and pie or bar charts. These cover domain modeling, application flows, database schemas, and process documentation.

Can I document database schemas with ERDs generated from text?▼

Yes, you can document database schemas by generating Entity Relationship Diagrams from text-based syntax. These ERDs are created as text files, making them easy to update and store with your code for version-controlled database schema documentation.

What is the best way to visualize application flows without manual drawing?▼

The best way to visualize application flows is using text-based sequence diagrams that generate flow documentation automatically. This method replaces manual drawing tools by converting simple text syntax into clear, maintainable diagrams reviewable in version control.

Do I need any external dependencies to create C4 architecture diagrams?▼

No external dependencies are required to create C4 architecture diagrams. The Skill operates independently using text-based syntax to generate architecture visualizations, allowing you to model system architecture directly within your documentation files.
