Quality

Content

46%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 action-rich with executable code across most plot types, but it is noticeably verbose with explanation Claude already knows, and its progressive disclosure is undercut by references and scripts that do not exist in the bundle. Workflows are topical rather than sequenced with checkpoints.

Suggestions

Create the referenced bundle files (references/plot_types.md, references/styling_guide.md, references/api_reference.md, references/common_issues.md, scripts/plot_template.py, scripts/style_configurator.py) or remove the dangling references so navigation is not broken.

Trim concept explanations Claude already knows (the object hierarchy, pyplot-vs-OO basics) and the 'Additional Resources'/'Integration' padding to raise conciseness.

Provide a sequenced 'create -> style -> save' workflow with explicit validation steps (e.g., verify the figure rendered, check for overlapping elements) to lift workflow clarity.

DimensionReasoningScore

Conciseness

At ~350 lines it explains concepts Claude already knows (the Figure/Axes/Artist/Axis hierarchy, the pyplot-vs-OO distinction, generic best-practice prose) and pads with 'Additional Resources' and 'Integration' sections, matching 'noticeably verbose; several unnecessary explanations or padded sections'; not a 1 because the code blocks themselves are useful.

2 / 5

Actionability

It provides concrete, mostly copy-paste-ready code for plot types, subplots, styling, saving, and 3D plots, matching 'mostly executable guidance; concrete code with minor gaps'; only minor gaps (some examples reference undefined variables like x, y1) keep it from 5.

4 / 5

Workflow Clarity

Content is organized by topic with numbered subsections rather than as a sequenced end-to-end workflow, and there are no explicit validation checkpoints; plotting is non-destructive so the 3-cap for missing validation does not apply, but the absence of a clear task sequence lands it at the 'steps listed but checkpoints implicit' level.

3 / 5

Progressive Disclosure

The body signals one-level-deep references to references/*.md and scripts/*.py, but none of those bundle files actually exist in the skill directory, so the navigation is broken; per the rubric this is 'references present but not clearly signaled / buried' territory and warrants a low score.

Description

53%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 clear about what matplotlib is but entirely omits when Claude should invoke it, capping completeness. It is moderately specific and distinct but lacks synonym coverage and explicit trigger guidance.

Suggestions

Add an explicit 'Use when...' trigger clause naming concrete scenarios (e.g., 'Use when creating line, scatter, bar, or heatmap plots, or when the user mentions matplotlib, charts, or figures').

Broaden trigger terms with natural synonyms users say ('charts', 'figures', 'data viz') and file extensions where relevant.

List a few more concrete actions (saving to PNG/PDF/SVG, subplot layouts, styling) to lift specificity toward 4-5.

DimensionReasoningScore

Specificity

Names the domain ('Python's foundational visualization library') and one concrete capability ('creating static, animated, and interactive plots'), but does not enumerate multiple specific actions like saving, styling, or subplot layouts, so it stops at the 'domain + 1-2 actions' anchor rather than 4.

3 / 5

Completeness

It clearly answers 'what' (a foundational visualization library for static/animated/interactive plots) but contains no 'Use when...' trigger clause, which per the rubric caps completeness at 3.

3 / 5

Trigger Term Quality

It includes natural terms a user might say ('plots', 'visualization') but omits common synonyms and extensions users actually use ('charts', 'figures', 'heatmaps', file types), matching the 'some relevant keywords but missing common variations' anchor.

3 / 5

Distinctiveness Conflict Risk

The phrasing stakes out a clear niche ('Python's foundational visualization library') that is unlikely to fire for unrelated skills, with only minor overlap risk against other plotting skills; not a 5 because it lacks distinctive trigger phrasing.
