What problem does it solve? Founders and builders often start coding before confirming anyone actually wants the product. This Skill runs a structured office-hours session that stress-tests demand, target users, and the narrowest paid wedge before any code is written, producing a design document as the only output. ## Core Features & Use Cases - Startup Mode Diagnostic: Six forcing questions covering demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit, with smart routing based on product stage (pre-product, has users, has paying customers). - Builder Mode Brainstorming: Design-thinking collaboration for hackathons, side projects, learning, and open source ideas. - GO / KILL / PIVOT Decision: Ends with a concrete verdict and one actionable assignment, saved as a design doc for the project. - Use Case: A solo founder with a new SaaS idea runs the session before writing code, gets pushed to name a specific paying customer and a one-week wedge, and walks away with a validated (or killed) concept and a design doc. ## Quick Start Ask the assistant to run the validate skill to pressure-test your new product idea before building anything.
