Quality

Content

67%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.

The body is an actionable, well-structured matplotlib reference with strong code examples and a real bundle, but it is verbose in its explanatory prose and inlines content that overlaps with the reference files.

Suggestions

Trim overview and concept paragraphs (Figure/Axes hierarchy, interface rationale) that restate what Claude already knows about matplotlib.

Move the inlined styling and plot-type catalogs into references/ and leave brief pointers, reducing duplication with styling_guide.md and plot_types.md.

Make code examples self-contained so variables like x, y1, matrix, X/Y/Z are defined or noted as assumed inputs.

DimensionReasoningScore

Conciseness

Mostly code-driven and useful, but several prose sections explain concepts Claude already knows (the Figure/Axes/Artist hierarchy, interface rationale, overview paragraphs) and could be tightened.

3 / 5

Actionability

Abundant concrete, executable code across plot types, styling, saving, and 3D with real parameters; minor gaps where examples reference undefined variables (x, y1).

4 / 5

Workflow Clarity

Well-organized into numbered workflows (1-6) with clear sequencing; no validation checkpoints, but plotting is non-destructive so they are not critical, fitting the simple-skill allowance.

4 / 5

Progressive Disclosure

Real references/ (4 files) and scripts/ (2 files) are clearly signaled one level deep, but a fair amount of styling/plot-type content that duplicates the reference files is inlined in the body.

Description

71%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.

The description is specific and action-dense with good trigger-term coverage, but lacks an explicit 'Use when...' trigger clause, capping completeness. It is mostly distinct from sibling visualization skills.

Suggestions

Add an explicit trigger clause such as 'Use when creating plots, charts, or figures for scientific visualization or publication.'

Include common synonyms users say ('charts', 'graphs', 'figures') to broaden trigger-term coverage.

Tighten 'Foundational plotting library.' to avoid generic framing that overlaps with other viz skills.

DimensionReasoningScore

Specificity

Lists multiple concrete plotting actions (line, scatter, bar, histograms, heatmaps, 3D, subplots) plus export formats PNG/PDF/SVG, giving comprehensive coverage of the library's capabilities.

5 / 5

Completeness

A clear 'what' is present via the action list, but there is no explicit 'Use when...' clause; the trailing 'for scientific visualization and publication figures' only weakly implies when, which caps completeness at 3 per the missing-trigger guideline.

3 / 5

Trigger Term Quality

Strong natural terms (line plots, scatter, histograms, heatmaps, subplots, publication figures) and file extensions, but missing common synonyms like 'charts' or 'graphs' and no 'Use when...' phrasing.

4 / 5

Distinctiveness Conflict Risk

Matplotlib-specific extensions (PNG/PDF/SVG) and concrete plot types carve a clear niche, but 'scientific visualization'/plotting still overlaps with seaborn or plotly skills.
