Turns vague feature requests into testable acceptance criteria before you write code. It inspects your repo first, asks minimal questions about things it can't infer, then produces observable criteria with verification methods. Choose Quick Capture for straightforward changes or Full Brief for anything touching auth, data migrations, or external APIs. It won't block you on trivial stuff, but it will flag when you're about to do something destructive without thinking it through. The real value is in how it separates technical facts it can discover from business constraints it can't, so you're not guessing what "done" means halfway through implementation.
