Design statistically rigorous A/B tests and interpret experiment results. Use when asked to design an experiment, run an A/B test, calculate sample size, interpret test results, or assess whether an experiment was successful. Produces a complete experiment design with hypothesis, sample size, run time, success criteria, and risk flags — or a results interpretation with ship/iterate/kill recommendation.
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
# Experiment Designer Skill Produce rigorous experiment designs from product hypotheses, and interpret results with statistical and practical significance — so you can defend every decision to a sceptical engineering lead or data scientist. ## Required Inputs Work from what is given. If any of these is missing, still produce the complete output: fill each gap with a reasonable assumption marked *(assumed, confirm)* and list those assumptions at the end. Ask a question first only when the core subject itself is missing (there is nothing to write about). **For experiment design:** - Hypothesis (what change, what metric, what expected movement) - Current baseline metric value - Minimum detectable effect (MDE) — the smallest lift worth caring about - Available daily sample size **For results interpretation:** - Control and variant results (raw numbers or percentages) - P-value or confidence interval - Run duration (days) - Any anomalies observed during the test ## Two-Phase Process ### Phase 1: Experiment Design 1. Restate hypothesis as: "If we [change], we expect [metric] to [move by X%] because [reason]" 2. Define control and variant clearly …

How to install
mdr add mohitagw15856/pm-claude-skills/experiment-designer@sha256:34569a9d49a6a84fThe line at the top of this page pins the label git:20261011.d31ce81, 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.
