prompt-test

A/B test content variations by quality score: create a named test, log each variant (scored via eval-runner.py on hallucination, content quality, and readability), and get a winner declaration with margin of victory, confidence level, per-dimension trade-offs, and auto-reject flags. Produces a decision-ready recommendation plus reusable insights about which approach wins for this brand. Triggers on "/digital-marketing-pro:prompt-test", "which headline style works better", "A/B test these subject lines", "compare two versions of this copy", "show the results of my content test". Reads the brand profile and guidelines for evaluation context; compares eval scores, not live audience performance — pair with /digital-marketing-pro:ab-test-plan for real-traffic experiments.
