mermaid-diagrams

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.

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.

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.

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.

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.
