72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The content is a tight, well-organized template spec that captures non-obvious gotchas like the Chart.js ResizeObserver height trap and the requirement to parse real data. Its main gap is the lack of a complete executable HTML scaffold and explicit render-validation checkpoints.
Suggestions
Add a minimal complete HTML scaffold (doctype, CDN script tags, one canvas wrapper, one KPI card) so the guidance is copy-paste ready.
Include an explicit validation step, e.g. after rendering, confirm each chart parent has a fixed height and that parsed data is non-empty before drawing.
Show a concrete data-parsing snippet (e.g. parsing a CSV/JSON blob into the chart's datasets) to make the "parse actual data" requirement actionable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a lean bulleted spec with no padding and no explanation of concepts Claude already knows; even the longer ResizeObserver bullet is genuinely non-obvious critical knowledge that earns its tokens, matching the level-3 anchor. | 3 / 3 |
Actionability | It gives concrete specifics (Chart.js/ECharts, jsdelivr CDN, a div wrapper snippet with exact style, pixel ranges, table styling attributes), but there is no complete copy-paste executable HTML example, so it stops at the level-2 anchor of concrete but incomplete guidance. | 2 / 3 |
Workflow Clarity | Sections are ordered top-to-bottom (header, KPI grid, charts, table, insights, footer) with explicit constraints ("must parse actual data", fixed-height rule), but there is no validate→fix→retry checkpoint for rendering, fitting the level-2 anchor of sequenced steps with missing validation. | 2 / 3 |
Progressive Disclosure | The skill is under 50 lines with no external references needed and is organized as a clear bulleted template list, so per the simple-skills guideline progressive disclosure scores 3 on well-organized sections alone. | 3 / 3 |
