What problem does it solve? Founders and builders often jump straight to writing code before validating whether an idea has real demand, a specific user, or a viable wedge. This Skill forces structured thinking before any implementation, producing a design document instead of code. ## Core Features & Use Cases - Startup Mode: Runs a YC-style diagnostic with six forcing questions covering demand reality, status quo workarounds, desperate specificity, narrowest wedge, user observation, and future-fit, with smart routing based on product stage. - Builder Mode: Acts as an enthusiastic design partner for hackathons, side projects, open source, and learning projects, helping find the most exciting version of an idea. - Design Doc Output: Saves the session outcome as a design document, with a hard gate preventing any code writing or implementation. - Use Case: A founder says "I have an idea for an AI tool for developers." The Skill asks what evidence proves someone would be upset if it disappeared, pushes past vague answers like "enterprises in healthcare," and ends with one concrete next action. ## Quick Start Ask the assistant to run office hours on your new product idea before writing any code.
