86%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 well-structured, opinionated, and highly actionable skill body that delegates detail to real reference files and includes pre-query validation and result-interpretation feedback loops. The only slack is a small amount of definitional over-explanation in the Calculated Fields section.
Suggestions
Trim or remove the definitional sentence "Calculated fields are per-event expressions evaluated at query time. They transform, classify, and combine existing fields without re-instrumenting code." — the patterns and guardrails already convey the purpose.
Consider consolidating the query workflow into one explicit numbered sequence (find_queries → find_columns → broad COUNT/GROUP BY → add filters → interpret with heuristics) so the end-to-end flow with checkpoints is unambiguous.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Largely lean and assumes competence, but the two-sentence opener "Calculated fields are per-event expressions evaluated at query time. They transform, classify, and combine existing fields without re-instrumenting code." explains a concept Claude already knows and could be trimmed; fits the efficient-with-minor-over-explanation anchor rather than the fully-lean one. | 4 / 5 |
Actionability | Fully executable, copy-paste-ready patterns throughout — `COUNT, P99(duration_ms), HEATMAP(duration_ms)`, `MUL(IF($error, 1, 0), 100)`, `IF(GTE($http.status_code, 500), "5xx", ...)`, `BUCKET($duration_ms, 500, 0, 3000)`, plus concrete tool calls like `find_columns`, `find_queries`, `query_result_json`, and `run_bubbleup`. | 5 / 5 |
Workflow Clarity | A "Before Every Query" pre-flight checklist with explicit validation (`Validate columns with find_columns before querying`) plus result-driven feedback loops (P99/P50 > 10x → run HEATMAP; large OTHER → increase limit), but there is no single numbered end-to-end sequence with validate-fix-retry, so it sits below the 5 anchor. | 4 / 5 |
Progressive Disclosure | Concise overview that keeps syntax/bulk detail out of SKILL.md and points to five well-signaled one-level-deep reference files (all verified present in references/) plus cross-references to sibling skills; navigation is easy and references are not nested. | 5 / 5 |
