The body is lean: a single prompt template with a numbered structure and four short tips, with no padding explaining concepts Claude already knows. Every section earns its place.

The prompt template is copy-paste ready with concrete numbered sections, explicit instructions ("Call out statistical significance", "Ship, iterate, or kill"), and clear input placeholders, giving executable guidance rather than abstract direction.

A clear 10-step sequence covers the readout (1-7) then the stakeholder comms (8-10), and includes an input-validation checkpoint ("If the above is blank, ask the user"). This is not a destructive or batch operation, so missing retry feedback loops do not cap the score.

This is a simple single-purpose skill under 50 lines with no bundle files, and the body is organized into clear Prompt Template and Tips sections, which satisfies the rubric's allowance for well-organized simple skills to score 3 without external references.

"Summarize experiment results, call a winner, and draft a stakeholder-ready recommendation" lists multiple concrete actions, matching the anchor for listing several specific actions rather than naming a domain alone.

It states both what the skill does (summarize, call a winner, draft a recommendation) and an explicit "Use when an A/B test is complete and you need to communicate results" trigger, clearly answering what and when.

"A/B test" and "communicate results" are natural phrases, but the description omits common variations users would say like "experiment readout", "analyze this test", or "did it win", so coverage is partial rather than strong.

"Experiment results" and "A/B test" scoped with stakeholder communication define a clear niche with distinct triggers that would not commonly conflict with other skills.
