37%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is concise and well-organized as a decision guide (when to use, boundaries, integration), but it fails as execution guidance: it contains no code or commands, never references the bundled scripts, and provides no sequenced workflow with validation. The skill ships a toolchain the body never teaches Claude to use.
Suggestions
Add concrete, executable guidance: name the libraries (matplotlib/seaborn/plotly) and show how to invoke the bundled scripts (data_validator.py, data_analyzer.py, chart_generator.py) with example commands.
Add a short sequenced workflow with a validation checkpoint (e.g., 1. validate data with data_validator.py, 2. analyze with data_analyzer.py, 3. generate with chart_generator.py), re-validating on errors.
Link the overview to the bundled materials so progressive disclosure is explicit (e.g., 'See references/visualization_best_practices.md for chart-type selection').
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean, assumes Claude's competence, and avoids explaining concepts Claude already knows; it never pads with library tutorials or basic definitions, so every token earns its place. | 3 / 3 |
Actionability | The body gives only abstract guidance ("Plotting trends...", "Choosing a sensible chart type and axis treatment") with no executable code, commands, or library names, and it never references the shipped scripts (chart_generator.py, data_analyzer.py), so it describes rather than instructs. | 1 / 3 |
Workflow Clarity | There is no sequenced workflow in the body, only categorical sections, and the bundled data_validator.py is never mentioned despite data validation being part of the toolchain, matching 'steps unclear or missing; no validation mentioned'. | 1 / 3 |
Progressive Disclosure | The body is cleanly sectioned (not a wall of text), but it never signals or links to the bundled scripts, reference docs, or assets, so the overview-to-detail navigation the rubric rewards is missing even though a bundle ships with the skill. | 2 / 3 |
