ab-test-plan
Design A/B and multivariate tests. Use when: sample size calculation, testing hypothesis, CRO experimentation.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# /digital-marketing-pro:ab-test-plan ## Purpose Dedicated A/B test planning with a structured hypothesis framework, statistical sample size calculation, variant design, and monitoring plan. Produces a complete experiment specification with statistical rigor and clear decision criteria. ## Input Required The user must provide (or will be prompted for): - **Element to test**: The specific page, component, or experience being tested (landing page headline, CTA button, pricing page layout, email subject line, checkout flow, form design, etc.) - **Current conversion rate**: Baseline conversion rate for the metric being tested (or best estimate) - **Desired minimum detectable effect (MDE)**: The smallest improvement worth detecting. **MDE is ABSOLUTE by default** — expressed in the same units as the baseline (baseline 5.0% and you want to catch a +1.0 percentage-point lift, i.e. 5.0% → 6.0% ⇒ `--mde 0.01 --mde-type absolute`). To express it as a **relative** lift instead (a 10% relative improvement on a 5% baseline = 5.5% ⇒ `--mde 0.10 --mde-type relative`), pass `--mde-type relative`. This distinction is the single most common sample-size error: the same "10%" read as absolute vs. rela

Design A/B and multivariate tests. Use when: sample size calculation, testing hypothesis, CRO experimentation.
How do I install it?
Run `npx skills add indranilbanerjee/digital-marketing-pro --skill ab-test-plan --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From indranilbanerjee/digital-marketing-pro, a repository with 700 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
