Takes a rough plan document and runs you through an adaptive interview to turn it into a complete spec. The interview adjusts its depth based on complexity, asking 10-15 questions for simple features or up to 28 for cross-system work. It covers foundations, technical architecture, UX, risks, and operationalization, focusing on non-obvious questions and edge cases rather than restating what's already clear. Includes a spec reviewer agent that scores output on completeness, consistency, clarity, and edge case handling. Honestly this is what you should probably do before building anything substantial, but most of us skip straight to code and regret it later.
