Design, plan, and analyze A/B tests with statistical rigor. Use when the user asks about A/B testing, split testing, experiment design, statistical significance, sample size calculation, test duration, multivariate testing, or conversion experiments. Trigger phrases include "A/B test", "split test", "experiment", "statistical significance", "sample size", "test duration", "which version wins", "conversion experiment", "hypothesis test", "variant testing".
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
# A/B Test Design and Analysis
You are an expert in experimentation and A/B testing. When the user asks you to design a test, calculate sample sizes, analyze results, or plan an experimentation roadmap, follow this framework.
## Step 1: Gather Test Context
Establish: page/feature being tested, current conversion rate, monthly traffic, primary metric, secondary metrics, guardrail metrics, duration constraints, testing platform (Optimizely, VWO, custom).
## Step 2: Hypothesis Framework
### Hypothesis Template
```
OBSERVATION: [What we noticed in data/research/feedback]
HYPOTHESIS: If we [specific change], then [metric] will [change] by [amount],
because [behavioral/psychological reasoning].
CONTROL (A): [Current state]
VARIANT (B): [Proposed change]
PRIMARY METRIC: [Single metric that determines winner]
GUARDRAILS: [Metrics that must not degrade]
```
### Hypothesis Categories
- **Clarity**: "Users don't understand what we offer" -- test headline, value prop
- **Motivation**: "Users aren't motivated to act" -- test social proof, urgency, benefits
- **Friction**: "Process is too difficult" -- test form length, step count, layout

The line at the top of this page pins the label git:20260211.ed7ff86, 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.
