Quick Review

Excellent comprehensive skill for A/B testing. The description clearly covers when to invoke the skill with multiple keyword triggers. The task knowledge is outstanding—provides detailed frameworks for hypothesis formation, sample size calculation, metrics selection, variant design, and analysis methodology that would be difficult for a CLI agent to reproduce efficiently. Structure is very clear with logical sections and helpful tables/templates. Novelty is good: while A/B testing concepts are established, synthesizing best practices, avoiding common mistakes, and providing decision frameworks in a conversational guide meaningfully reduces token cost versus a CLI agent researching these topics. Minor opportunity: could be slightly more prescriptive about the exact interaction flow, but the 'Questions to Ask' section addresses this well. Strong skill overall.
