What problem does it solve? High-stakes product and design decisions often suffer from unchallenged requirements, hidden assumptions, and unclear priorities. This Skill gives you a structured, read-only second opinion that questions requirements, separates facts from assumptions, and produces one unified verdict with a reversible experiment plan. ## Core Features & Use Cases - Requirement Challenge and Subtraction: Classifies each candidate requirement as keep, delete, or defer based on whether it directly supports a one-sentence product promise. - Fixed-Priority Conflict Resolution: Adjudicates trade-offs in a fixed order: safety and truthfulness, core user value, technical feasibility, end-to-end experience consistency, then speed and cost. - Reversible Experiment Design: Outputs a minimal prototype with target users, timebox, pass criteria, and stop conditions for the next validation step. - Use Case: Before committing to an expensive, hard-to-reverse architecture or brand decision, ask for a second opinion to get a unified verdict, one engineering objection, one experience objection, and the smallest experiment to de-risk the direction. ## Quick Start Ask the agent to review your product direction with first-principles and product taste, and return a unified decision, objections, and the next reversible experiment.
