Growth experiments are the activity teams do most carelessly. Hypothesis is implicit; metric is improvised; kill conditions are not defined. The result is experiments that run forever waiting for significance and decisions made by intuition rather than data.

The /surge-experiment skill designs a single experiment with rigor: testable hypothesis, exact metric and measurement, baseline, MDE, required run time, explicit kill conditions. One unambiguous design per experiment.

Tonone's /surge-experiment skill designs single growth experiments with hypothesis, metric, baseline, MDE, run time, and kill conditions.
