experimentation SKILL.md skillA
experimentation from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Design an A/B test that can answer its question — hypothesis, randomization unit, power, duration, pre-registered analysis — and read the result honestly, including a null. Use when someone proposes testing a change, asks how long a test must run or whether a result is real, when a test is about to be stopped early, or when a flat result is being read as "no difference". Not for defining the metric itself (product-analytics), not for a change too small or too rare to power, and not for…
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
# Experimentation Most experiments fail before they launch: an unmeasurable hypothesis, a unit that leaks between arms, or a sample that was never going to detect the effect anyone cared about. Reading results is the short part. The design is where the answer is won or lost. ## When this fires A change is about to be tested, a running test is about to be read or stopped, or a result is being turned into a decision. It also fires as a refusal: when the traffic cannot support a test worth running, saying that early is the valuable output. ## Five states, not one - **Designed** — hypothesis, unit, primary metric, power and duration written down. - **Launched** — assignment is live and exposures are being logged. - **Read** — analysed at the pre-registered time, after sanity checks pass. - **Conclusive** — the result distinguishes the hypothesis from its absence at the stated power. - **Shipped** — a human decided to roll it out. Never a consequence of the other four. ## Procedure 1. **Write a falsifiable hypothesis with a direction and a size.** "Moving the plan selector above the fold will increase trial starts by at least 5% relative, because users currently scroll past …

How to install
mdr add nahid-sparktales/agent-dispatcher/experimentation@sha256:e116b7f5fe59e4c6The line at the top of this page pins the label git:20260919.a0d4f55, 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.
