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 definitions.
  • Documentation: Visualize system architecture, document code structure, model databases, and communicate technical concepts.
  • Use Case: You need to document the database schema for a new feature. Use this Skill to generate an Entity Relationship Diagram (ERD) directly from your table definitions.

Quick Start

Create a class diagram showing a User class with name and email attributes.

Frequently Asked Questions about mermaid-diagrams

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

FAQPage Schema
How do I generate sequence diagrams from text for documenting application flows?

Sequence diagrams can be generated directly from text definitions using Mermaid syntax to visualize application flows. This approach allows you to document interactions between system components without manual drawing tools.

Can I visualize database schemas with an ERD generated from table definitions?

Yes, database schemas can be visualized by generating Entity Relationship Diagrams (ERDs) directly from your table definitions. This text-based approach produces maintainable diagrams that can be version-controlled alongside your code.

What types of architecture diagrams can I create using text-based code modeling?

Text-based code modeling supports generating 9 types of diagrams including class diagrams, sequence diagrams, flowcharts, ERDs, C4 architecture diagrams, state diagrams, git graphs, gantt charts, and pie/bar charts.

How do I document system architecture so it can be version-controlled with my code?

System architecture can be documented using text-based Mermaid syntax to generate diagrams that are version-controlled alongside your code. This eliminates manual drawing tools and transforms complex technical concepts into clear, maintainable visual definitions.

Does this approach to diagram generation require manual drawing tools or external dependencies?

Text-based diagram generation eliminates the need for manual drawing tools and requires no external dependencies. Diagrams are created directly from simple text definitions, facilitating clear visualization and documentation of technical concepts.

What is the best way to model domain classes and code structure for technical documentation?

Modeling domain classes and code structure is best handled by generating class diagrams using Mermaid's text-based syntax. This method transforms complex technical concepts into clear, maintainable diagrams for version-controlled documentation.
