json-canvas
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 sickn33/agentic-awesome-skills --skill json-canvas --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# JSON Canvas Skill ## When to Use - Use when creating or editing `.canvas` files for Obsidian. - Use for mind maps, flowcharts, visual note structures, or connected canvases. - Use when the user explicitly mentions JSON Canvas or Obsidian Canvas files. ## File Structure A canvas file (`.canvas`) contains two top-level arrays following the [JSON Canvas Spec 1.0](https://jsoncanvas.org/spec/1.0/): ```json { "nodes": [], "edges": [] } ``` - `nodes` (optional): Array of node objects - `edges` (optional): Array of edge objects connecting nodes ## Common Workflows ### 1. Create a New Canvas 1. Create a `.canvas` file with the base structure `{"nodes": [], "edges": []}` 2. Generate unique 16-character hex IDs for each node (e.g., `"6f0ad84f44ce9c17"`) 3. Add nodes with required fields: `id`, `type`, `x`, `y`, `width`, `height` 4. Add edges referencing valid node IDs via `fromNode` and `toNode` 5. **Validate**: Parse the JSON to confirm it is valid. Verify all `fromNode`/`toNode` values exist in the nodes array ### 2. Add a Node to an Existing Canvas 1. Read and parse the existing `.canvas` file 2. Generate a unique ID that does not collide with existing node or edge IDs 3. Choose positio

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --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.

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.
