Quality

Content

87%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a lean, highly actionable reference with executable code, decision tables, and APA templates, well-organized into clear sections. Its main gap is workflow clarity: the worked example does not enforce assumption checks as explicit validation branches.

Suggestions

Turn the analysis flow into an explicit validation-gated workflow: after the normality/variance check, branch to the non-parametric alternative when assumptions fail, rather than printing the t-test unconditionally.

Add a brief "if p is non-significant, report effect size and CI; do not claim no effect" checkpoint in the worked example to close the implicit feedback loop.

DimensionReasoningScore

Conciseness

The body is lean reference material — decision tables, executable code, effect-size thresholds, and APA templates — with no padding explaining basic concepts Claude already knows.

3 / 3

Actionability

Provides copy-paste-ready executable Python (scipy, pingouin), concrete test-selection tables, effect-size cutoffs, and filled-in APA report templates — fully actionable rather than descriptive.

3 / 3

Workflow Clarity

A sequence exists (descriptives → normality → test) and a checklist is present, but validation checkpoints are implicit: the example runs the t-test regardless of the normality result, with no explicit branch or feedback loop.

2 / 3

Progressive Disclosure

Content is organized into eight clearly headed sections with no nested or multi-level references; as a self-contained reference skill with no bundle files, well-organized sections satisfy progressive disclosure.

Description

77%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description cleanly states what the skill does and when to use it with concrete capabilities, but its trigger vocabulary is narrow and the domain is broad enough to risk overlap with general data-analysis skills. Adding natural trigger variations would lift the weaker dimensions.

Suggestions

Broaden trigger terms to include natural phrasings users actually say, e.g. "Use when choosing a statistical test, running t-tests/ANOVA/correlation, computing effect sizes, or writing APA-style results."

Sharpen distinctiveness by foregrounding the academic/APA-reporting angle, e.g. "for academic papers and APA-formatted statistical reporting," to reduce overlap with general data-analysis skills.

DimensionReasoningScore

Specificity

Lists three concrete capabilities — "test selection, execution code, and APA format guidelines" — matching the multi-action anchor rather than the single-domain anchor at 2.

3 / 3

Completeness

Explicitly answers both: "Use when planning or reporting statistical analysis" (when) and "provides test selection, execution code, and APA format guidelines" (what), in third person.

3 / 3

Trigger Term Quality

"statistical analysis" is a natural term a user would say, but common variations (stats, p-value, hypothesis test, t-test/ANOVA, APA report) are absent, so coverage is partial.

2 / 3

Distinctiveness Conflict Risk

The APA-reporting niche is fairly distinct, but the broad trigger "statistical analysis" could overlap with generic data-analysis or data-science skills, so it is not a clear isolated niche.
