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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# JSON Canvas Skill
## Mindset
JSON Canvas is a minimal open standard: nodes positioned on an infinite grid, connected by edges. The entire spec fits in two arrays. Design with this simplicity in mind — when a layout feels complex, it is usually a positioning or ID-management problem, not a schema problem.
**When to apply:** Creating or editing `.canvas` files, building visual mind maps or flowcharts in Obsidian, or generating canvas files programmatically.
**When NOT to apply:** The user wants a Markdown note, a database view (use Bases), or a diagram format that outputs to image/PDF — JSON Canvas is a live interactive format, not a rendering target.
## 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"`)
…Read the whole file at its exact version.
How to install
mdr add pantheon-org/tekhne/json-canvas@sha256:187283b1235ecf4eThe line at the top of this page pins the label git:20260316.13efaab, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
