This diagnostic helps you stop thrashing during revision by enforcing the hierarchy that matters: fix structure before polishing sentences. It identifies six revision states like "can't see problems anymore" or "editing never ends" and gives you concrete interventions for each. The six-pass system keeps you from wasting time on prose in scenes you'll cut later. Most useful when you're paralyzed by competing feedback or knee-deep in line edits before confirming your story actually works. The "darlings folder" advice for delete-phobic writers is solid. Basically stops you from optimizing the wrong level at the wrong time.
