json-canvas

Quick Review

Excellent comprehensive skill for creating and editing JSON Canvas files. The description clearly indicates when to use this skill (working with .canvas files, visual canvases, mind maps, flowcharts, Obsidian). The documentation is exceptionally thorough with complete spec coverage, multiple detailed examples (simple canvas, project board, research canvas, flowchart), validation rules, and layout guidelines. The structure is well-organized with clear sections progressing from basics to advanced examples. The skill provides meaningful value by encapsulating the entire JSON Canvas spec (nodes, edges, colors, positioning) into a reusable format, saving significant tokens when a CLI agent would otherwise need to generate canvas files from scratch or reference external documentation repeatedly. Minor improvement possible: could add a quick-reference command summary at the top for common operations.
