Quality

Content

20%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The skill body is verbose and conceptual rather than instructional, with no executable code or references to the bundled scripts and assets that are present. It reads as a generic overview rather than actionable guidance.

Suggestions

Replace conceptual prose with concrete, executable examples: show how to invoke scripts/data_analyzer.py and generate a chart with a specific library (e.g. matplotlib) and sample code.

Link to the actual bundled resources — reference scripts/data_analyzer.py, the chart_templates/ and example_data/ directories — so Claude can navigate to them.

Cut filler sections (Overview, Integration, Resources) that restate what Claude already knows, and add validation checkpoints to the visualization workflow.

DimensionReasoningScore

Conciseness

The body is padded with high-level conceptual explanation Claude already knows (e.g. 'empowers Claude to transform raw data into compelling visual representations', 'helps users understand complex data') and generic filler sections that add no actionable value.

1 / 3

Actionability

Despite a bundled data_analyzer.py script, the body gives no executable code, commands, or concrete library guidance — it only describes steps abstractly ('Claude generates the visualization using appropriate libraries').

1 / 3

Workflow Clarity

A sequence exists (analyze, select, generate) but there are no validation checkpoints or error-recovery feedback loops, and the listed steps are vague rather than concrete commands.

2 / 3

Progressive Disclosure

Sections are organized, but the body never references the actual bundled files (scripts/data_analyzer.py, chart templates, example data) that exist, so navigation to supporting materials is missing.

Description

55%

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 covers a clear domain and includes a use-when clause, but it relies on generic trigger verbs and lists only one broad action rather than multiple specific capabilities. It is solid but not exemplary.

Suggestions

Replace generic trigger verbs (generate, create, scaffold) with concrete situational triggers users would actually say, e.g. 'Use when the user asks to plot data, visualize a dataset, or chart relationships between variables'.

Enumerate multiple specific actions beyond 'generate', such as 'select chart type, render plots, and export figures'.

Tighten the description to remove the trailing blank line and redundant phrasing for a cleaner, more specific statement.

DimensionReasoningScore

Specificity

Names the domain (plots, charts, graphs) and the single action of generation with automatic type selection, but does not list multiple distinct concrete actions like the score-3 anchor (e.g. fill, merge).

2 / 3

Completeness

It states what the skill does and includes a 'Use when...' clause, but the 'when' trigger guidance relies on generic verbs (generate/create/scaffold) rather than explicit situational conditions, leaving the when partly implied.

2 / 3

Trigger Term Quality

Includes natural terms (visualization, plot, chart, graph) but the listed triggers (generate, create, scaffold) are generic verbs rather than domain-specific variations users would say, missing common phrasings.

2 / 3

Distinctiveness Conflict Risk

The visualization domain is reasonably distinct, but generic trigger verbs (generate, create) could overlap with many other generation skills, so conflict risk remains moderate.
