Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, highly actionable reference for the JSON Canvas format with concrete examples, explicit validation checkpoints in every workflow, and appropriate offloading of full examples to a single reference file. The only minor lever is overall length, which is justified by the spec detail but keeps conciseness at 4.

Dimension	Reasoning	Score
Conciseness	The body is dense with useful, non-obvious reference material (field tables, color presets, ID format, newline pitfall) and avoids explaining concepts Claude already knows, but the full per-node-type attribute tables and layout tables make it somewhat extensive rather than lean.	4 / 5
Actionability	Copy-paste-ready JSON examples cover every node type and edges, plus concrete ID-generation format, color presets, and suggested dimensions, fully covering the common cases for this data-format skill.	5 / 5
Workflow Clarity	Four numbered workflows each include an explicit "Validate" checkpoint, a dedicated Validation Checklist section, and an error-recovery note ("If validation fails, check for duplicate IDs, dangling edge references..."), matching the score-5 anchor with feedback loops and a checklist.	5 / 5
Progressive Disclosure	SKILL.md serves as a well-organized overview/spec while full canvas examples are correctly offloaded to a single one-level-deep, clearly signaled reference (references/EXAMPLES.md), with external spec links kept separate.	5 / 5

Description

83%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that clearly states both capabilities and trigger conditions with concrete, natural-sounding terms. Its only weakness is a slightly limited action vocabulary and minor overlap risk from generic visual-canvas trigger words.

Dimension	Reasoning	Score
Specificity	"Create and edit" names two concrete actions and the description enumerates the manipulated components (nodes, edges, groups, and connections), giving more concrete detail than the score-3 anchor though it stops short of the multiple distinct verbs in the score-5 example.	4 / 5
Completeness	Explicitly answers what ("Create and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections") and when ("Use when working with .canvas files, creating visual canvases, mind maps, flowcharts, or when the user mentions Canvas files in Obsidian"), matching the score-5 anchor with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural user terms — ".canvas files", "visual canvases", "mind maps", "flowcharts", and "Canvas files in Obsidian" — with good coverage of the file extension, but misses common synonyms like "diagrams" or "knowledge graphs" that would push it to 5.	4 / 5
Distinctiveness Conflict Risk	The .canvas extension and Obsidian anchoring carve a clear niche, but the mind maps/flowcharts triggers create minor overlap risk with general diagramming skills, keeping it just below 5.	4 / 5
