This is a well-structured, concise decision-guide skill that excels at providing clear constraints and rules for Vizro chart/component selection. Its main weakness is the lack of executable code examples for key patterns like @capture('graph') custom charts and AG Grid setup, which are described but not demonstrated. The progressive disclosure is reasonable but relies on bundle files that weren't provided for verification.
Suggestions
Add a minimal executable code example for @capture('graph') showing pre-aggregation inside a custom chart function, since the skill emphasizes this is needed for 'most bar and line charts'.
Add a brief code snippet showing the canonical AG Grid pattern (vm.AgGrid with dash_ag_grid) rather than only pointing to an example file in another skill's bundle.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient throughout. It uses tables for chart selection, bullet points for rules, and avoids explaining concepts Claude already knows (e.g., what Plotly Express is, what a bar chart is). Every section delivers actionable constraints without padding. | 3 / 3 |
Actionability | The skill provides strong, specific guidance (e.g., 'never use vm.Table', color rules, when to use @capture) but lacks executable code examples. Key patterns like @capture('graph') aggregation functions, KPI card usage, and AG Grid setup are described but not shown with copy-paste ready code snippets. | 2 / 3 |
Workflow Clarity | For a decision-oriented skill (chart selection, color rules, component choice), the workflow is clear: the skill provides unambiguous decision criteria for chart type, color handling, custom charts vs inline, KPI cards, and tables. There are no destructive or batch operations requiring validation checkpoints, so the clear decision trees and explicit constraints are sufficient. | 3 / 3 |
Progressive Disclosure | The skill references chart-best-practices.md and an example_ag_grid.py in another skill's bundle, with clear signals for when to load the deep-dive file. However, no bundle files were provided, so we cannot verify the referenced paths exist. The cross-skill reference (../dashboard-build/references/examples/) is a potential fragility point, and the inline content is well-sized but could benefit from a clearer quick-start section. | 2 / 3 |
