78%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a lean, well-structured instruction skill with a strong workflow and validation checklist, but it stops short of executable rendering examples. Adding a minimal concrete code or command snippet for the render step would lift actionability.
Suggestions
Add a short executable snippet (Matplotlib or inline SVG) for the render step so the most common case is copy-paste ready.
Make the QA feedback loop explicit (e.g., 'If recomputed values differ or the file fails to open, fix the encoding/render and re-run QA') to reach full workflow clarity.
Optionally split the chart-family decision table into a reference file if the skill grows, keeping SKILL.md as the overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean, assumes Claude's competence, and avoids explaining what charts are or how libraries work; every line is actionable guidance. It is not below 5 because there is no padded or unnecessary explanation, and 5 is the scale max. | 5 / 5 |
Actionability | The chart-family decision tree and the encoding/QA checklists are concrete guidance, but there is no executable rendering code or copy-paste example (e.g., a Matplotlib/SVG snippet), leaving the render step at a high level. It is not 4 because executable code or specific commands are absent, and not 2 because the decision framework and checklists go beyond minimal hints. | 3 / 5 |
Workflow Clarity | A clear six-step Workflow is followed by a QA section with validation checkpoints (recompute plotted values, confirm the file opens, check scales/labels). It is not 5 because there is no explicit error-recovery feedback loop (e.g., 'if QA fails, fix and re-render'), and not 3 because checkpoints are clearly present rather than implicit. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines, single-purpose, and organized into well-signaled sections (Workflow, Visual quality, QA) with no need for external references; no bundle files exist. Per the rubric's simple-skill note, this earns 5 on structure alone. | 5 / 5 |
