Create and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections. Use when working with .canvas files, creating visual canvases, mind maps, flowcharts, or when the user mentions Canvas files in Obsidian.
npx skills add anbeime/skill --skill json-canvas --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# JSON Canvas Skill This skill enables skills-compatible agents to create and edit valid JSON Canvas files (`.canvas`) used in Obsidian and other applications. ## Overview 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](https://jsoncanvas.org/spec/1.0/). ## File Structure A canvas file contains two top-level arrays: ```json { "nodes": [], "edges": [] } ``` - `nodes` (optional): Array of node objects - `edges` (optional): Array of edge objects connecting nodes ## 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 ### Z-Index Ordering Nodes are ordered by z-index in the array: - First node = bottom layer (displayed below others) - Last node = top layer (displayed above others) ### Generic Node Attributes All nodes share these attributes: | Attribute | Required | Type | Description | |-----------|----------|------|-------------| | `id` | Yes | string | Unique identifier for the node | | `type` | Yes | str

What does the json-canvas skill do?
Create and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections. Use when working with .canvas files, creating visual canvases, mind maps, flowcharts, or when the user mentions Canvas files in Obsidian.
How do I install it?
Run `npx skills add anbeime/skill --skill json-canvas --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From anbeime/skill, a repository with 4,714 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
