Use this skill when you want to test what works in outbound instead of guessing: "A/B test my cold emails", "design an outbound experiment", "which variant won", "testing plan for our sequences". Picks the variable worth testing (list, angle, offer, first line, CTA, channel, timing), writes the hypothesis, splits the audience fairly, sets the sample size and decision rule, and reads the result honestly, including when it is a tie. Produces a test plan, a log entry and the decision.
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
Use this to run outbound tests that produce decisions. Most outbound "tests" compare 40 sends to 40 sends and crown a winner by noise. ## Inputs - The current campaign and its baseline numbers. - The metric to improve (usually positive reply rate or meetings per 100 contacts). - How many contacts per week the team can send to the test. ## The play ### 1. Test the biggest lever first Impact order, roughly: **list and segment** > **angle and offer** > **first line and personalization** > **CTA** > **subject line** > **send time**. Testing send time while the list is wrong wastes a month. ### 2. Write a hypothesis "Leading with the hiring trigger instead of the pain will raise positive replies for SDR leaders, because the trigger shows why now." One variable changes; everything else stays the same. ### 3. Size it Required contacts per variant depend on baseline and the lift you want to detect: | Baseline positive reply rate | Detect 2x lift | Detect 1.5x lift | | --- | --- | --- | | 1% | ~2,300 per variant | ~7,700 per variant | | 2% | ~1,150 | ~3,800 | | 4% | ~550 | ~1,900 | …

How to install
mdr add prosyo-ai/gtm-skill/outbound-ab-test@sha256:9fe333cf84e2ccbeThe 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.
