Content
22%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This SKILL.md functions almost entirely as a table of contents with no substantive content in the body itself. It lacks any executable code, concrete examples, or actual workflow steps, making it essentially an index page rather than a useful skill document. The progressive disclosure approach of linking to sub-skills is reasonable in concept but poorly organized and unverifiable without bundle files.
Suggestions
Add a concrete quick-start example showing a minimal D3 visualization (e.g., a simple bar chart in ~15 lines) so the skill body itself is actionable without requiring sub-skill navigation.
Fill in the empty 'Core workflow' section with a clear numbered sequence (e.g., 1. Set up → 2. Choose pattern → 3. Structure code → 4. Add interactivity → 5. Test responsiveness) with brief inline guidance at each step.
Organize the 23 sub-skill links into logical groups (Setup, Chart Types, Interactions, Scales, Data & Performance, Accessibility & Styling) with brief one-line descriptions of when to use each.
Remove the explanatory sentence about what D3.js is ('D3.js (Data-Driven Documents) excels at binding data to DOM elements...') since Claude already knows this.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The overview paragraph explains what D3.js is, which Claude already knows. The 'When to use d3.js' section adds some value but is somewhat verbose. The bulk of the file is a link list, which is efficient, but the introductory text could be tightened. | 2 / 3 |
Actionability | The SKILL.md contains zero executable code, no concrete commands, and no specific examples. It is entirely a table of contents pointing to sub-skills with no actionable guidance in the body itself—not even a quick-start snippet or minimal working example. | 1 / 3 |
Workflow Clarity | The 'Core workflow' heading is empty with no actual workflow steps described. The numbered sub-skill links (1-4) hint at a sequence but provide no inline guidance, validation checkpoints, or sequencing logic. There is no feedback loop or error recovery guidance. | 1 / 3 |
Progressive Disclosure | The skill does attempt progressive disclosure by linking to 23 sub-skills, which is a reasonable structure. However, the links are not well-categorized (setup, chart types, interactions, scales, and meta-concerns are all in one flat list), the section headers are redundant with the link text, and without bundle files we cannot verify the references resolve. The organization could be significantly improved with grouping. | 2 / 3 |
