This skill enables Claude Code to create and edit valid JSON Canvas files (.canvas) used in Obsidian and other applications. JSON Canvas is an open file format for infinite canvas data. Canvas files use the .canvas extension and contain valid JSON following the JSON Canvas Spec 1.0. A canvas file contains two top-level arrays: nodes (optional): Array of node objects edges (optional): Array of edge objects connecting nodes Nodes are objects placed on the canvas. There are four node types: text - Text content with Markdown file - Reference to files/attachments link - External URL group - Visual container for other nodes Nodes are ordered by z-index in the array: First node = bottom layer (displayed below others) Last node = top layer (displayed above others) All nodes share these attributes: | Attribute | Required | Type | Description | |-----------|----------|------|-------------| | id | Yes | string | Unique identifier for the node | | type | Yes | string | Node type: text, file, link, or group | | x | Yes | integer | X position in pixels | | y | Yes | integer | Y position in pixels | | width | Yes | integer | Width in pixels | | height | Yes | integer | Height in pixels | | color
