Choose by one rule
Use when you keep comparing options and want to apply one clear decision rule.
I am choosing between [OPTIONS WITH KNOWN FACTS]. I need this for [PURPOSE]. My decision rule is [ONE REQUIREMENT OR THRESHOLD]. Apply that rule step by step using only the facts supplied. Give one short line per option showing pass, fail, or unknown and why. If exactly one passes, recommend it in one sentence. If several pass, ask me for one tie-breaker and wait. If none passes or a fact is unknown, ask for the single fact or rule change needed next and wait. Do not invent product features, return policies, or urgency.

Sample input For my rainy bike commute, I am choosing a $60 backpack with a laptop sleeve and a $95 backpack described as waterproof. My rule is that it must cost no more than $100 and be explicitly described as waterproof; no waterproof description is supplied for the $60 bag.
Sample AI reply $60 bag: unknown; it is within budget, but its waterproof status is not supplied. $95 bag: pass; it is within budget and described as waterproof. What does the $60 bag’s listing say about waterproofing?
