Conciseness

The body is mostly efficient with tight bullet lists and concrete gates, but sections like 'Key Principles (Non-Negotiable)' and the motivational 'Final Reminder' restate earlier content and could be trimmed.

Actionability

Concrete gating questions, a 5-step tracking-verification checklist with specific thresholds (±5%, within 30 seconds, 5+ events), and a results decision table give mostly executable guidance; a few sections remain conceptual checklists rather than worked examples.

Workflow Clarity

A clearly numbered gate sequence (1-8) with explicit hard stops, a dedicated pre-Gate-8 verification checklist, and feedback loops ('stop and resolve it') match the anchor for clear sequencing with explicit validation and error-recovery checklists.

Progressive Disclosure

Two bundle files exist (test-templates.md, sample-size-guide.md) that map directly onto the sample-size and documentation sections, but the body never links or signals them, and content that belongs in those references is inlined.

Specificity

Names the A/B-test domain and a few concrete mechanisms ("mandatory gates for hypothesis, metrics, and execution readiness") but does not enumerate several specific concrete actions, so it is not comprehensive enough for a 4.

Completeness

It gives a clear "what" (a structured gated guide for A/B test setup) but provides no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the rubric guidelines.

Trigger Term Quality

"A/B tests" is a natural, relevant keyword, but synonyms and variations users say (split test, experiment, conversion optimization) are missing and there is no trigger clause.

Distinctiveness Conflict Risk

"A/B test setup" is a mostly-distinct niche unlikely to trigger for unrelated skills, though it could overlap slightly with general experimentation/analysis skills, keeping it below 5.
