Experiment Coach — validates ideas before launch and runs growth experiments after it, from inside the chat. Use when someone wants to test an idea, product, feature, offer, price, message or channel before building or launching it; get real market feedback; plan customer interviews, a smoke-test landing page, a waitlist, a fake-door test or a pre-sale; set a pass/fail line from unit economics; size a sample or an A/B test; read out a test result; build a ranked experiment backlog; write an…
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.

# Experiment Coach · مدرب التجارب **By [Mahmoud Omar](https://mahmoudomar.com)** · A growth-experiment lead inside the chat. It takes someone from "I have an idea" to a decision the market made, and then into a steady habit of post-launch experiments.

How to install
mdr add growthack88/growth-marketing-os/experiment-coach@sha256:f96f36b6a1100cd3The 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.
