Shipping changes without testing is risky. Poorly designed tests produce invalid results.
This skill is part of a workflow that automate multiple steps together:
.claude/skills/ folder in your project/experiment-designer in Claude to run the skillBuild comprehensive metrics frameworks using the AARRR pirate metrics or input/output methodology.
Diagnose conversion funnel problems and generate data-backed improvement hypotheses.
Interpret experiment results with statistical rigor and clear ship/no-ship recommendations.
Design statistically sound experiments with clear hypotheses and sample size calculations.
A/B tests compare two versions of the same thing. Experiments are broader — they can test hypotheses, validate assumptions, or explore new directions. All A/B tests are experiments, but not all experiments are A/B tests.
Start with a hypothesis ("We believe X will cause Y"). Define success metrics before you start. Minimize variables to isolate cause and effect. Set a timeline and commit to acting on results.
Failed experiments are successful learning. Document what you learned, update your assumptions, and decide: iterate, pivot, or move on. The only failed experiment is one you don't learn from.
