Design or critique an A/B test or controlled product experiment with statistical rigor — pre-registered falsifiable hypothesis, sample-size/power up front, a full business cycle, one primary metric plus guardrails, segment + long-term reads, and a pre-set iterate/pivot/persevere decision. Catches the defaults Claude misses: peeking/early stopping, tiny samples, no guardrails, vanity metrics, "it won" with no learning loop. Trigger when asked to set up or review an A/B test, design an experiment…

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'pm-experimentation-ab' ] || [ -L ~/.agents/skills/'pm-experimentation-ab' ]; then echo 'A skill folder named pm-experimentation-ab already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Uxcel-Lab/product-skills' "$d" && git -C "$d" checkout --quiet '5007cd0241ccaa51ae2e4681f9618912dc10e239' -- 'pm/processes/experimentation-ab' && mkdir -p ~/.agents/skills && cp -R "$d"/'pm/processes/experimentation-ab' ~/.agents/skills/'pm-experimentation-ab' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'pm-experimentation-ab' ~/.claude/skills/'pm-experimentation-ab' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
