63%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The content is highly actionable with executable examples and a clear workflow, but it is over-long, inlines material that belongs in its existing reference files, and ships broken asset references. Tightening the body and fixing the missing assets would lift the structure and token-efficiency scores.
Suggestions
Move the per-chart-type implementations (chord, heatmap, pie, force) and the full 'Scales reference' into references/d3-patterns.md and scale-reference.md, leaving concise overviews and links in SKILL.md to cut length and padding.
Either create the referenced assets/chart-template.js, interactive-template.js, and sample-data.json, or remove those bullet points from the Resources section so no broken references remain.
Trim definitional asides ('A chord diagram shows relationships...', 'A heatmap uses colour to encode values...') that restate concepts Claude already knows; keep only the actionable code and integration notes.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is very long (~810 lines) with many full chart implementations inlined and explanatory asides ('A chord diagram shows relationships...', 'A heatmap uses colour to encode values...') that restate concepts Claude already knows; mostly efficient but noticeably padded. | 3 / 5 |
Actionability | Extensive copy-paste-ready functions covering common patterns (bar, line, scatter, chord, heatmap, pie, force, tooltips, zoom, transitions); minor gaps where snippets reference undefined `g`/`svg`/`circles` selections. | 4 / 5 |
Workflow Clarity | A clear numbered core workflow (set up → choose pattern → structure → responsive) is present with a 'Common issues' troubleshooting section; not a destructive/batch skill so the validation cap does not apply, but explicit checkpoints inside steps are only implicit. | 4 / 5 |
Progressive Disclosure | A Resources section signals real references/*.md files, but the body also references assets/chart-template.js, interactive-template.js, and sample-data.json that do not exist, and large reference-style content (scales reference, all chart patterns) is fully inlined rather than delegated to the dedicated reference files that exist. | 3 / 5 |
