What problem does it solve? Founders and product teams often commit resources to ideas based on optimism rather than evidence. This Skill pressure-tests a product or business idea by identifying the assumption most likely to kill it and designing the cheapest credible test before any building begins. ## Core Features & Use Cases - Structured Viability Assessment: Walks through problem severity, competitive landscape, demand signals, differentiation, and execution risk in a fixed six-step workflow. - Evidence Discipline: Distinguishes evidence from inference and speculation, refuses to endorse ideas without support, and names fatal flaws plainly. - Actionable Verdict Output: Delivers a Go / No-Go / Pivot verdict with ranked risks, a minimal MVP definition, and one falsifiable, time-boxed validation experiment with a success threshold. - Use Case: A founder asks whether a meal-planning app for diabetics is worth building. The Skill maps competitors and substitutes, checks demand signals like search intent and community discussions, then recommends a two-week landing-page test with a signup threshold before writing any code. ## Quick Start Ask the assistant to validate whether your product or business idea is worth building, describing the target customer, problem, and proposed solution.
