Evaluation
AI-evaluated 2026-09-03: Solid step-by-step experiment design with a clear per-experiment output schema (assumption, experiment, metric, success threshold) and a varied method list. Includes explicit responsible-testing principles like risk mitigation for production A/B tests, though the skill only designs experiments rather than runs them.
