# JSON Canvas Skill ## 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 position (`x`, `y`) that avoids overlapping existing nodes (leave 50-100px spacing) 4. Append the new node object to the `nodes` array 5. Optionally add edges connecting the new node to existing nodes 6. **Validate**: Confirm all IDs are unique and all edge references resolve to existing nodes ### 3. Connect Two Nodes 1. Identify the source and target node IDs 2. Generate a unique edge ID 3. Set `fromNode` and `toNode` to the source and target IDs 4. Optionally set `fromSide`/`toSide` (top, right, bottom, left) for ancho
