mermaid-diagrams
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes, algorithms, user journeys), entity relationship diagrams (database schemas), C4 architecture diagrams (system context, containers, components), state diagrams, git graphs, pie charts, gantt charts, or any other diagram type. Triggers include requests to "diagram", "visualize", "model", "map out", "show the flow", or when explaining system architecture, database design, code structure, or user/application flows.

Create professional software diagrams using Mermaid's text-based syntax. Mermaid renders diagrams from simple text definitions, making diagrams version-controllable, easy to update, and maintainable alongside code. All Mermaid diagrams follow this pattern: Key principles: First line declares diagram type (e.g., classDiagram, sequenceDiagram, flowchart) Use %% for comments Line breaks and indentation improve readability but aren't required Unknown words break diagrams; parameters fail silently Choose the right diagram type: 1. Class Diagrams - Domain modeling, OOP design, entity relationships Domain-driven design documentation Object-oriented class structures Entity relationships and dependencies 2. Sequence Diagrams - Temporal interactions, message flows API request/response flows User authentication flows System component interactions Method call sequences 3. Flowcharts - Processes, algorithms, decision trees User journeys and workflows Business processes Algorithm logic Deployment pipelines 4. Entity Relationship Diagrams (ERD) - Database schemas Table relationships Data modeling Schema design 5. C4 Diagrams - Software architecture at multiple levels System Context (systems and u
