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.
# Experimentation & A/B Testing Skill ## When to Use - Validating new subject lines or creative. - Testing segmentation hypotheses (persona vs behavior). - Optimizing cadence, timing, or automation triggers. ## Framework 1. **Hypothesis** – define expected uplift + rationale. 2. **Metric Selection** – primary (open/click/conv) + guardrails (unsubs, spam). 3. **Sample Sizing** – ensure stat significance (min 500 recipients per variant or use power calculator). 4. **Execution** – randomize, keep variants isolated, limit simultaneous tests. 5. **Analysis** – use z-test or Bayesian uplift; document learnings. ## Templates - Experiment brief (hypothesis, segments, KPI, risk guardrails). - Variant table (control vs test inputs, creative asset links, owner). - Calculator sheet for minimum detectable effect + sample size. - Post-test debrief doc capturing learnings + rollout plan. ## Experiment Ideas - Subject line vs preview text combos. - CTA placement (hero vs footer). - Personalization depth (basic vs dynamic modules). - Wait times between touches. ## Tips - Run no more than two tests per journey simultaneously. - Recycle learnings into playbooks + automation templates. - Segment resul

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill ab-testing-gtmagents-gtm-agents-3 --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 majiayu000/claude-skill-registry, a repository with 534 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.
