Obsidian Viz Skill

Generate Obsidian-compatible visualization files from text descriptions or image inputs.

Processing Flow

Step 0 - Input Type Detection

If user sends an image:

1. Load modules/image-reader.md
2. Execute image type recognition and content extraction
3. Output structured Markdown summary
4. If image contains diagrams, proceed to Step 1
5. If image is text/screenshot only, end process

If user provides text description:

• Proceed directly to Step 1

Step 1 - Tool Selection

Load modules/chart-router.md and select the most appropriate tool based on content type:

• Excalidraw: Hand-drawn style, architecture diagrams, free layout, concept maps
• Mermaid: Technical documentation, flowcharts, sequence diagrams, state diagrams, ER diagrams
• Canvas: Large knowledge networks, interactive exploration, data visualization

Step 2 - Format Specification Loading

Load the corresponding reference file based on the selected tool:

• mermaid → references/mermaid.md
• excalidraw → references/excalidraw.md
• canvas → references/canvas.md

Important: Must read the corresponding reference file before generating any content.

Step 3 - Output Format Selection

Standard Format (when user explicitly requests "standard format" or "excalidraw.com"):

• Mermaid → .mmd file
• Excalidraw → .excalidraw file
• Canvas → .html file

Obsidian Format (default):

• Mermaid → .md file (with mermaid code block)
• Excalidraw → .md file (with Excalidraw JSON)
• Canvas → .canvas file

Step 4 - Generate File

1. Strictly follow format specifications in reference file
2. Output to ~/.openclaw/workspace/outputs/<filename>.<ext>
3. Explain to user how to open the file in Obsidian

Usage Instructions

Excalidraw Files

Obsidian Mode (.md):

• Place in any vault folder

• Supports import to any Excalidraw instance

Mermaid Files

Obsidian Mode (.md):

• Place anywhere in vault

Notes

1. Must load reference first: Skipping this step will produce incorrectly formatted files
2. Chinese support: All tools natively support Chinese, no escaping needed
3. File path: Output files are uniformly placed in ~/.openclaw/workspace/outputs/ directory
4. Fallback strategy: If primary tool fails, automatically try alternative tool
5. Node count limit: For more than 30 nodes, recommend user to split or use Canvas
