Build JSON Canvas Diagrams
JSON Canvas files are hard to edit by hand without breaking IDs or links. This skill guides creation, updates, and validation for Obsidian-compatible canvases.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "json-canvas" from https://skillstore.io/skills/kepano-json-canvas.md and its manifest at https://skillstore.io/api/skills/kepano-json-canvas/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "json-canvas". Create a mind map for a product launch plan.
Expected outcome:
The skill returns a ready-to-save canvas with a central launch node, grouped workstreams, milestone nodes, and labeled dependency edges.
Using "json-canvas". Add three research sources to my existing canvas.
Expected outcome:
The skill adds file and link nodes, places them near the research summary, connects each source, and preserves existing IDs.
Using "json-canvas". Validate this canvas before I open it in Obsidian.
Expected outcome:
The skill reports duplicate IDs, missing target nodes, invalid side values, and unescaped text issues, then proposes corrected entries.
Security Audit
SafeAll static findings are false positives caused by Markdown backticks, JSON examples, documentation URLs, and ordinary canvas validation terms. The skill is documentation-only and provides guidance for creating JSON Canvas files; no executable scripts, network requests, system reconnaissance, or prompt injection attempts were found.

Why this score Evidence Confidence: HighWhat You Can Build
Plan a Knowledge Map
Create a connected canvas that organizes ideas, notes, and relationships for a new topic.
Build a Project Board
Generate grouped sections for tasks, status lanes, and dependencies in an Obsidian canvas.
Organize Research Sources
Map papers, meeting notes, diagrams, and web references into a connected research workspace.
Try These Prompts
Create a JSON Canvas mind map for this topic: [topic]. Include one central idea, three supporting ideas, and clear connecting labels.
Open my existing .canvas file and add these items as new nodes: [items]. Place them without overlap and connect them to related nodes.
Convert this outline into a JSON Canvas layout: [outline]. Use groups for major sections and edges for dependencies or sequence.
Review this .canvas file for duplicate IDs, dangling edges, invalid node fields, malformed text strings, and layout collisions. Fix issues and summarize changes.
Best Practices
- Describe the desired layout, node types, and relationships before generating a large canvas.
- Validate IDs and edge references after every edit to avoid broken connections.
- Use consistent spacing and group bounds so the canvas remains readable in Obsidian.
Avoid
- Do not paste multiline text without escaping line breaks for JSON strings.
- Do not create edges before confirming both node IDs exist.
- Do not reuse example IDs when adding multiple nodes or edges.
