Use when the user asks to "design an A/B test", "set up a creative/landing test", "run an incrementality test", or "is this result statistically and practically material?"; produces a hypothesis, variant matrix, sample-size/duration/power plan, and a documented effect/uncertainty read from own exported results. It applies only a precommitted owner-approved action rule; the statistical helper never chooses a business action. Not for producing variants — use ad-creative-builder; not for reading…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Ad Test Designer Designs paid-ad creative/landing A/B/n and incrementality tests and reads them out: hypothesis, variant matrix, sample-size/duration/power plan, effect size, uncertainty, practical-effect status, and guardrail state. This skill owns **experiment design + statistical interpretation**. It may apply an owner-approved, precommitted action rule, but it never treats a p-value or helper output as an automatic business decision. It does not produce variants (`ad-creative-builder`), read back one already-shipped change (`paid-measurement-loop`), or do cross-channel reporting (`performance-analyzer`). ## Quick Start ```text Design an A/B test for two landing-page hero variants. Baseline CVR is 3%, I want to detect a 15% lift. Goal is DR. ``` ```text I have 4 RSA creative variants to test on a prospecting set. Build the variant matrix, sample size, and run duration. ``` ```text Here's my finished test results CSV (variant, sessions, conversions). Is the winner significant — promote or kill? ``` ## Skill Contract …

How to install
mdr add aaron-he-zhu/aaron-marketing-skills/ad-test-designer@sha256:7160f23c77de20dfThe line at the top of this page pins the label v20.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
