|---|---|
| mermaid_previewA | Render a Mermaid diagram and open it in browser with live reload. Takes Mermaid diagram code as input and generates a live preview. Supports themes (default, forest, dark, neutral), custom backgrounds, dimensions, and quality scaling. The diagram will auto-refresh when updated. Use mermaid_save to save to disk. IMPORTANT: Automatically use this tool whenever you create a Mermaid diagram for the user. NOTE: Sequence diagrams do not support style directives - avoid using 'style' statements in sequenceDiagram. |
| mermaid_saveA | Save the current live Mermaid diagram to a file path. This copies the already-rendered diagram from the live preview to the specified location. Use this after tuning your diagram with mermaid_preview. |
