85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A dense, well-structured skill body: executable code throughout, a clearly gated seven-step workflow, and clean progressive disclosure into two real reference files. The only weakness is a brief Overview that restates A/B-testing fundamentals Claude already knows.
Suggestions
Trim or relocate the Overview's explanation of A/B-test variance/sample-size basics; keep only the citation anchors and assume Claude's familiarity to push conciseness to a 3.
Consider moving the false-positive probability aside (1 - 0.95^10 = 40%) into the anti-patterns reference if it is motivational rather than load-bearing for the correction step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The Overview paragraph explains A/B-testing basics Claude already knows ('A/B tests are sensitive to variance; they require a large sample size…'), which the rubric penalizes; the rest is lean code and direct steps, so it sits at 'mostly efficient but includes some unnecessary explanation' rather than fully lean. | 2 / 3 |
Actionability | Provides fully executable, copy-paste-ready code (chi2_contingency, ttest_ind, mannwhitneyu, multipletests, NormalIndPower) plus concrete YAML input and MDE formats — matching the score-3 'fully executable code' anchor. | 3 / 3 |
Workflow Clarity | Steps 1–7 are clearly sequenced with explicit validation gates (power-analysis gate in Step 4, 'both statistical AND practical significance' in Step 5, peeking→sequential testing in Step 7) and feedback loops (inconclusive→'re-run at higher N'), matching the score-3 anchor. | 3 / 3 |
Progressive Disclosure | The body is an overview that splits detail into two real, one-level-deep, well-signaled references (references/output-example.md, references/anti-patterns.md, both verified present), matching the score-3 'clear overview with well-signaled one-level-deep references' anchor. | 3 / 3 |
