88%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 highly actionable with concrete tool calls, complete chart-spec examples, and a well-sequenced workflow featuring explicit validation and retry feedback loops; its only weaknesses are minor redundancy in the closing recap and a dangling reference to a non-existent bundle file.
Suggestions
Remove or merge the trailing ✅/❌ recap list, since it restates the a–d workflow and the execute_sql prohibition already covered above.
Resolve the references/system-query-log.md reference — either add the file to a references/ bundle or clarify that it belongs to the clickhouse-system-queries skill.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient and assumes Claude's competence (no explaining what charts are), but the trailing ✅/❌ checklist recap and the repeated execute_sql prohibition in steps (c) and (d) duplicate content already stated in the workflow, leaving minor trimmable redundancy. | 4 / 5 |
Actionability | It gives fully executable, copy-paste-ready guidance: exact tool calls (validate_sql, skill with ['sql-expert'], skill_resource), exact legendOption/values rules, and two complete chart-spec JSON examples covering line/bar and pie cases. | 5 / 5 |
Workflow Clarity | The mandatory ordered workflow (a–d) has an explicit validation checkpoint (validate_sql before the spec), a feedback loop (retry up to 3 times by fixing SQL and re-validating), and a gating condition ('Only proceed if success: true'), with a closing checklist. | 5 / 5 |
Progressive Disclosure | Content is well-organized into clear sections (WORKFLOW, CHART TYPE RULES, CRITICAL RULES, OUTPUT FORMAT) and appropriately inline for an ~80-line skill, but the reference to references/system-query-log.md points to a file absent from the bundle, a minor navigation gap. | 4 / 5 |
