a-b-testing from leadmagic/gtm-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add leadmagic/gtm-skills/a-b-testing@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Design statistically sound GTM experiments for copy, channels, landing pages, sequencing, pricing, and funnel conversion. Produces hypothesis, sample-size logic, success metrics, test plan, analysis method, and scale/stop/kill recommendation. Use when planning A/B tests, split tests, or experiment roadmaps.
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
# A/B Testing ## Overview A/B Testing brings experimental rigor to GTM optimization. The core principle: most "optimizations" are guesswork dressed as strategy. Teams change subject lines because someone "feels" they're better, rewrite copy based on a single positive reply, or abandon channels because of one bad week. This skill prevents the waste of optimizing based on noise rather than signal. The non-obvious rule: statistical significance is necessary but insufficient. A statistically significant 10% improvement in open rate that produces 0% more meetings is a distraction. Optimize for downstream revenue metrics — reply rate, meeting rate, conversion rate — not vanity metrics. Every test must trace its impact through the full funnel. This skill produces: an Experiment Design Document with hypothesis, success metrics, power analysis, and methodology; a prioritized ICE/PIE test backlog; a 30/60/90-day testing roadmap; and a Results Analysis Report with statistical tests, confidence intervals, and scale/stop/kill recommendations. ## When to Use - User says "A/B test" or "split test" → activate this skill …

How to install
mdr add leadmagic/gtm-skills/a-b-testing@sha256:8b9a245d5b1fecafThe line at the top of this page pins the label v1.0.0, 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.
