86%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 an exemplary lean, instruction-only skill: a clear decision workflow for chart-family selection, concrete visual-quality rules, and a genuine QA checklist, all with zero token waste. The only gaps are the lack of a worked example and an explicit error-recovery loop after QA checks fail.
Suggestions
Add one compact worked example (e.g. a sample answer-oriented title with subtitle and annotation pattern) to make guidance copy-paste-ready for common cases.
Specify what to do when a QA check fails (e.g. 'if recomputed values disagree, fix aggregation and re-render before presenting') to close the feedback loop.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean and prescriptive throughout — every line instructs ("Verify the data grain, measures, dimensions, units...", "Recompute plotted values from the reviewed rows") with zero padding or explanation of concepts Claude already knows. Matches the 'lean and efficient; every token earns its place' anchor. | 5 / 5 |
Actionability | Highly concrete guidance: a relationship-to-chart-family mapping ("Relationship between numeric measures: scatter plot", "Contribution to change: waterfall") and explicit checks ("Recompute plotted values from the reviewed rows"). Falls short of fully executable/copy-paste-ready level 5 because it provides no worked example (e.g. a sample title, encoding spec, or rendered pattern). | 4 / 5 |
Workflow Clarity | A clear 6-step sequence (question → verify data → choose family → define encodings → render → inspect) plus a QA section serving as a validation checklist. Not a 5 because there is no explicit fix-and-retry feedback loop and some checkpoints (e.g. what to do when inspection reveals a problem) are left implicit. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines with well-organized sections (Workflow, Visual quality, QA) and no bundle files to disclose. Per the rubric's simple-skill guideline, this organization alone earns a 5 — no content belongs in separate reference files. | 5 / 5 |
