What problem does it solve? Teams often commit to building large initiatives before validating demand, wasting engineering effort on features nobody wants. This Skill frames epics as falsifiable hypotheses with lightweight experiments and measurable success criteria before any build commitment. ## Core Features & Use Cases - If/Then Hypothesis Framing: Structure an epic around the action, target persona, and expected outcome using the Lean UX hypothesis format. - Tiny Acts of Discovery: Design fast, low-cost experiments such as prototypes, concierge tests, and landing page tests to validate assumptions. - Validation Measures: Define quantitative and qualitative success criteria with realistic timeframes so weak ideas can be killed early. - Use Case: Before adding a Google Calendar integration to the roadmap, draft a hypothesis, run a Figma prototype test with 10 trial users, and only proceed if activation metrics hit the defined threshold. ## Quick Start Use the epic-hypothesis skill to frame my proposed Slack notifications epic as a testable hypothesis with experiments and validation measures.
