92%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.
A high-quality methodology skill body: executable SQL and a precise column table, a well-sequenced 9-step workflow with explicit validation checkpoints, and clean one-level-deep references to real bundle files. The only mild weakness is verbosity in the step-9 delta and grounding-recommendations prose.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and information-rich, assuming Claude's competence about ClickHouse rather than explaining basics, and every section earns its place; a few explanatory passages (notably the long step-9 delta guidance and the grounding-recommendations prose) could be tightened without losing clarity. | 4 / 5 |
Actionability | It provides copy-paste-ready SQL predicates ('query_duration_ms > 30000 OR exception_code IN (159, 160, 241)'), a concrete typed-column table, exact file references, and a fully specified numbered report structure covering the common cases. | 5 / 5 |
Workflow Clarity | The 9-step workflow is clearly sequenced with explicit validation checkpoints — step 1 confirms retention covers the window before trusting it, and step 9 forces comparable windows before quoting a delta — plus feedback loops like re-running until retention checks pass. | 5 / 5 |
Progressive Disclosure | SKILL.md is a clear methodology overview with well-signaled, one-level-deep references to three real files (query-patterns.md, materialization-analysis.md, hogql-deep-dive.md), each described in a dedicated References section, with bulk SQL patterns appropriately split out of the main file. | 5 / 5 |
