Create Obsidian Canvas (.canvas) files to visualize information, create mind maps, or organize notes spatially. Use this skill when the user wants to "see" their data, map out relationships, brainstorm topics, or convert text outlines into visual diagrams, even if they don't explicitly mention "Canvas."

Canvas Creator

Generate valid Obsidian .canvas JSON from text content. Read references/canvas-spec.md first for node/edge schema and a complete example.

Workflow

1. Analyze: Identify Root, Branches, Leaves from input.
2. Layout: MindMap (single root → radial) or Freeform (zones). Read references/layout-algorithms.md for positioning formulas.
3. Validate: All IDs unique · no overlaps (min gap: 400px H, 250px V) · all edge refs valid · groups before children in array.
4. Output: Raw JSON only — {"nodes": [...], "edges": [...]}. No wrapping text or code fences.

Gotchas

Chinese quotes: Double → 『』, Single → 「」, Standard double → \". Failing this breaks JSON.
Z-index: Groups → sub-groups → content nodes, in that order in the nodes array.
No emoji: Use color presets "1"–"6" instead.
Overlap: Node A at (0,0) with width=250 → Node B must start at x≥650 (250 + 400 gap).

Use this skill when the user wants to digest notes or articles into a structured wiki, ask questions answered from compiled knowledge, check wiki health, produce polished deliverables (blog posts, reports, slides), or verify whether wiki content is still up-to-date. Activate even if the user doesn't say "wiki" — phrases like "organize this", "digest this article", "look this up for me", "write a blog post", "check the knowledge base" all qualify.
