What problem does it solve? Founders waste months building products nobody wants. This Skill stops premature building by forcing evidence-based validation: it structures any raw idea into a Lean Canvas, identifies the Riskiest Assumption, designs honest customer tests, and produces a documented kill, pivot, or build decision before any code is written. ## Core Features & Use Cases - Lean Canvas Modeling: Drafts a one-page business model covering all 9 blocks, from Problem and Customer Segments to Revenue Streams and Unfair Advantage. - Riskiest Assumption Testing (RAT): Ranks assumptions by probability of being wrong times impact, then designs a test with a pass/fail threshold set before data collection. - Mom Test Interview Design: Generates past-behavior interview questions that avoid hypothetical "would you" phrasing, plus smoke tests and pre-order validation. - Pivot / Persevere Decisions: Applies pre-set kill criteria to test evidence and documents the decision with cited data. - Use Case: You have an idea for an AI finance app. Instead of asking "is this good?", the Skill drafts your Lean Canvas, flags the riskiest assumption, writes 5 Mom Test questions, and sets a kill threshold before you talk to a single customer. ## Quick Start Ask the assistant to validate your business idea by building a Lean Canvas and designing a riskiest assumption test with explicit kill criteria.
