Mermaid Diagrams Skill
Generate diagrams from text using Mermaid.
Requirements
@mermaid-js/mermaid-cli (npm install -g @mermaid-js/mermaid-cli)
Usage
Write Mermaid syntax to a .mmd file Run mmdc to render PNG/SVG Return the image to the user
Basic Command
mmdc -i input.mmd -o output.png -t dark -b transparent
Options
FlagDescription-iInput .mmd file-oOutput file (.png, .svg, .pdf)-tTheme: default, dark, forest, neutral-bBackground color (transparent, hex)-wWidth in pixels (default: 800)-HHeight in pixels-sScale factor (default: 1, use 2-3 for high-res)-cConfig JSON file for advanced theming
Supported Diagram Types
Flowchart: graph TD / graph LR Sequence: sequenceDiagram Class: classDiagram State: stateDiagram-v2 ER: erDiagram Gantt: gantt Pie: pie Mindmap: mindmap Timeline: timeline Git graph: gitGraph Quadrant: quadrantChart Block: block-beta
Workflow
Determine the best diagram type for what the user wants Write the .mmd file to /tmp/mermaid-<name>.mmd Render: mmdc -i /tmp/mermaid-<name>.mmd -o /tmp/mermaid-<name>.png -t dark -b transparent -s 2 Show the image to the user via Read tool Clean up temp files if not needed
Example: Architecture Diagram
graph TD A[Client] -->|HTTPS| B[API Gateway] B --> C[Auth Service] B --> D[App Server] D --> E[(PostgreSQL)] D --> F[(Redis Cache)]
Example: Sequence Diagram
sequenceDiagram participant U as User participant A as API participant DB as Database U->>A: POST /login A->>DB: Validate credentials DB-->>A: User record A-->>U: JWT token
Tips
Use graph LR for left-to-right flow, graph TD for top-down Keep node labels short โ detail goes in tooltips or notes Use subgraphs to group related components For dark backgrounds, use -t dark -b transparent Scale -s 2 or -s 3 for sharp images on retina displays Always use pty: false when calling mmdc
Theming
For custom colors, create a config JSON: { "theme": "base", "themeVariables": { "primaryColor": "#f59e0b", "primaryTextColor": "#1a1a1a", "primaryBorderColor": "#d97706", "lineColor": "#6b7280", "secondaryColor": "#10b981", "tertiaryColor": "#3b82f6" } } Then: mmdc -i input.mmd -o output.png -c config.json
Category context
Code helpers, APIs, CLIs, browser automation, testing, and developer operations.
