Purpose

How to Use This Skill

Understand the concept being visualized by reviewing the user's description
Select the appropriate diagram type from the diagram type options below
Reference the Mermaid syntax guide in references/mermaid-syntax.md for correct syntax
Create the diagram using Mermaid markdown syntax
Embed the diagram in the response using markdown code fence with mermaid language identifier
Follow best practices from references/mermaid-syntax.md to ensure clarity and correctness

Diagram Types Supported

Flowcharts: Decision trees, process flows, control flows
Sequence Diagrams: Interactions between components or systems over time
State Diagrams: State transitions and triggers
Class Diagrams: Object-oriented relationships and hierarchies
Entity Relationship Diagrams: Database schemas and data relationships
System Architecture Diagrams: Component relationships and service interactions

Key Mermaid Concepts

Node Syntax: Use NodeID[Label] for rectangular nodes, {Decision} for diamonds, (Rounded) for rounded nodes.

Edge Syntax: Connect nodes with --> for arrows, -.-> for dotted lines, and |Label| for edge descriptions.

Prohibited Symbols: Avoid unescaped quotes, pipes, brackets, colons, and semicolons in node IDs. Use underscores or hyphens for spaces in IDs, and quoted strings for complex labels.

For detailed syntax guidance, refer to references/mermaid-syntax.md.
