Transforms vague or ill-defined questions into clear, structured, and actionable "good problems" by extracting the core objective, identifying comparison dimensions, and applying structured reasoning. Use when a user wants to compare multiple options, evaluate trade-offs, make a decision between alternatives, or asks questions like "which is better", "pros and cons", "help me decide", "how should I choose", or "what are the trade-offs". Produces a rewritten problem statement with explicit comparison dimensions, a structured evaluation framework, and a decision-ready output format.
