65%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is highly actionable with abundant executable code and a clear core workflow, but it is over-long for a SKILL.md, duplicates material already held in the reference bundle files, and lacks explicit validation feedback loops in its workflow.
Suggestions
Move the inline Scales reference section and the detailed pattern implementations (chord, heatmap, pie, force-directed) into the existing references/d3-patterns.md and references/scale-reference.md, keeping SKILL.md as an overview that links to them.
Trim the Overview's explanation of what D3.js is — Claude already knows this — and lead instead with the When-to-use guidance and the core workflow.
Add explicit validation checkpoints to the core workflow (e.g., verify data is parsed/clean before scaling, confirm axes render before binding data) with a fix-and-retry loop rather than relying on the reactive Common issues list.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | At ~820 lines the body explains what D3 is ("D3.js (Data-Driven Documents) excels at binding data to DOM elements...") which Claude already knows, and inlines a full Scales reference section that duplicates references/scale-reference.md — mostly efficient but could be tightened and de-duplicated. | 2 / 3 |
Actionability | Provides fully executable, copy-paste-ready implementations (bar, chord, heatmap, pie, force-directed, tooltips, zoom) with concrete specifics rather than pseudocode. | 3 / 3 |
Workflow Clarity | A clear 4-step numbered Core workflow with input guards exists, but there are no explicit validate→fix→retry feedback loops or checklists; error recovery is a reactive Common issues list rather than workflow-integrated checkpoints. | 2 / 3 |
Progressive Disclosure | References are well-signaled (Resources section), one level deep, and all referenced files exist, but the SKILL.md inlines reference-grade content (full Scales reference, complete pattern implementations) that overlaps d3-patterns.md and scale-reference.md — content that should be separate is inline. | 2 / 3 |
