This is a competent skill that provides actionable, executable guidance for using Plotly with good API choice framing and concrete examples. Its main weaknesses are moderate verbosity — particularly the chart type catalog and common workflows sections that could be offloaded to reference files — and the fact that referenced bundle files don't actually exist. The skill would benefit from being trimmed to a tighter overview that delegates more content to the referenced files.
Suggestions
Move the 'Common Workflows' section content into a reference file (e.g., workflows.md) and replace with a brief summary linking to it, keeping the main SKILL.md as a concise overview.
Remove or significantly condense the chart type catalog in 'Core Capabilities' — Claude already knows Plotly's chart types; a simple 'See reference/chart-types.md for the full catalog' suffices.
Ensure the referenced bundle files (plotly-express.md, graph-objects.md, etc.) actually exist in the bundle to support the progressive disclosure structure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary content. The 'Core Capabilities' section listing all 40+ chart types by category is largely a catalog that Claude already knows. The 'Common Workflows' section repeats patterns already shown or easily inferred. The 'Additional Resources' section with external URLs adds little value. However, the code examples themselves are tight and the API choice guidance is useful. | 3 / 5 |
Actionability | The skill provides concrete, executable code examples throughout — scatter plots, subplots, exports, hover templates, Dash integration. Code is copy-paste ready with proper imports. Minor gap: some examples reference undefined variables (e.g., `correlation_matrix`, `z_data`, `data`) without setup, which reduces immediate executability. | 4 / 5 |
Workflow Clarity | The skill clearly sequences the API choice decision (px vs go), shows how to combine them, and provides clear export workflows with install prerequisites. The workflows section provides good multi-step patterns. No destructive or batch operations are involved, so validation checkpoints aren't critical. Minor gap: no explicit guidance on debugging common issues (e.g., kaleido installation failures, figure not rendering). | 4 / 5 |
Progressive Disclosure | The skill references five separate reference files (plotly-express.md, graph-objects.md, chart-types.md, layouts-styling.md, export-interactivity.md) with clear signaling, which is good structure. However, no bundle files were provided, so these references are unverifiable. Additionally, the main SKILL.md inlines substantial content (the entire 'Common Workflows' section, the chart type catalog, the Dash integration) that would be better placed in reference files, making the overview longer than necessary. | 3 / 5 |
