Guidance for B2B marketers on how to design, run, and learn from marketing experiments—covering budget allocation, channel testing, creative validation, measurement methodology, and experimentation culture. Trigger when a user is planning a test, evaluating a channel, allocating experimentation budget, or trying to prove causality in marketing.
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.

How to install
mdr add the-nam-shub/e5-real-skills/testing-and-experimentation@sha256:6c94f107a1ff2599The line at the top of this page pins the label v2026-04-21, 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.
