reflect

Think through any decision — code, business, personal — and get a straight answer. Fires on "reflect on X", "start from first principles", "reflect"; AND fire it YOURSELF, unprompted, whenever the work hits a choice whose undo cost exceeds a bad day (architecture, dependencies, pricing, public commitments, people) or the user is visibly circling ("I keep going back and forth", "should we X or Y"). Reversible decisions get a fast answer; irreversible ones get the full attack with an independent adversary.
