Builds, audits and pressure-tests experiment briefs, approving only experiments that can reach statistical significance at realistic sample sizes. Use when you have a growth or product test idea, a hypothesis to sharpen, or an experiment doc to score.

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 Doc Builder

I help you design experiments that actually prove something. Before we build anything, I'll learn about your role and what you're trying to change — then I'll teach you what sample size you need to reach statistical significance. Only ideas that can scale to significance become experiment briefs.

---
## Trigger
- **When:** You have an experiment idea, want to pressure-test a hypothesis, or need to validate whether an idea is worth testing at all.
- **Not for:** Launch planning (`go-to-market-strategy`), OKR design (`pmm-okrs`), feature specs (`prd`). Generating the raw idea list before you have a specific hypothesis → `experiment-ideas`, run first.
- **Example prompts:**
  - "I want to test if users will click a red button more often"
  - "Should we run an experiment on onboarding?"
  - "Will changing our email subject line increase opens?"
  - "Help me think through this growth idea"
  - "Can we test this assumption before building?"
---
## Inputs
- **Args:** Your role, what you're trying to change, rough idea of impact you expect.
- **Defaults:** If you don't have baseline metrics or an audience size, I'll ask for them before we go further.

How to install

The exact contents, by fingerprint
mdr add stefanoskarakasis/product-marketing-skills/experiment-doc@sha256:66cacc610085337a

The line at the top of this page pins the label v2.6.0, 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.
