What problem does it solve? Product teams struggle to identify the exact first moment users feel core value, making onboarding optimization guesswork. This Skill structures the discovery and validation of your product's Aha Moment through a hypothesis-experiment-data-refine cycle. ## Core Features & Use Cases - Hypothesis Generation: Analyzes retained vs churned user behavior, user interviews, and competitor onboarding to produce ranked Aha Moment hypotheses in a standardized format. - Experiment Design: Produces A/B test plans with control/treatment variants, metrics (D7 Retention, Activation Rate), sample sizes, and durations. - Data Verification & Iteration: Applies correlation, causation, and threshold analysis to confirm or reject hypotheses, then loops back with refined variants. - Use Case: A SaaS team suspects "creating a project within 24 hours" drives retention. The Skill drafts the hypothesis, designs a 14-day A/B test with 500 users per variant, and defines how to verify the result and update onboarding. ## Quick Start Ask the AI to find your product's Aha Moment and design an onboarding experiment to improve activation and reduce time to first value.
