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.
This is a strong, highly actionable reference: complete executable YAML for every component, explicit field rules and pitfalls, and a recommended composition workflow. Its main weaknesses are inlined content that belongs in reference files (progressive disclosure) and some duplication between per-component examples and the final complete example.
Suggestions
Move the Custom Chart section (metrics_sql query language, Vega-Lite rules, and its three full examples) into a references/ file (e.g. references/custom-charts.md) and keep a short pointer plus one inline example in SKILL.md.
Consider splitting the per-component API sections (or at least the rarer chart types like funnel, scatter, and combo) into a reference file, keeping the structure, layout, and composition guidance in the main body.
Trim the Complete Example or reduce it to a skeleton (rows + one or two representative components), since it repeats configurations already shown in full above.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and almost entirely product-specific configuration Claude would not know: YAML blocks, field rules ("Expressions reference dimension and measure names... not the underlying table columns"), and gotchas ("Required filters are implicitly pinned — do not also list them under pinned"). It stays at 4 rather than 5 because there is real duplication that could be trimmed — e.g. the ~135-line Complete Example re-assembles components already shown, and stacked_bar/stacked_bar_normalized/area_chart examples repeat near-identical x/y blocks. | 4 / 5 |
Actionability | Every component type ships complete, copy-paste-ready YAML covering the common cases — kpi_grid, leaderboard, line/bar/stacked/donut/heatmap/combo/scatter/funnel charts, pivot, table, image, and custom_chart with full metrics_sql queries and a valid Vega-Lite v5 spec. Horizontal-bar axis semantics are given as concrete rules ("put the measure on x and the dimension on y... sort: -x"), not vague direction. | 5 / 5 |
Workflow Clarity | "Dashboard Composition Best Practices" gives an explicit build sequence (Row 1 markdown context → Row 2 KPI grid → Row 3 leaderboard + time-series → additional rows) plus a chart-type selection guide, and "When to use canvas dashboards" vs explore dashboards orients the authoring decision. This is config authoring, not a destructive/batch operation, so no validation cap applies; it falls short of 5 only because there is no guidance on verifying the dashboard renders or recovering from schema errors. | 4 / 5 |
Progressive Disclosure | There are no bundle files at all (no references/, scripts/, or assets/), so ~1,540 lines of component API reference are inlined in SKILL.md. Section headers and structure are good, but clearly separable material — the ~200-line Custom Chart / metrics_sql / Vega-Lite guide and the per-component reference — stays inline with no one-level-deep references, matching "Some structure but could be better organized; content that should be separate is inline." | 3 / 5 |
