03 Have it ask you questions one at a time

What people usually ask

Help me plan a corrosion coupon test program for a cooling water loop.

What comes back

A full plan with assumed durations, materials and sampling points, and ten questions listed at the bottom after everything was already decided.

Ask this instead

I want to plan a corrosion coupon test program for a cooling
water loop. Here is what I know about the loop: <one paragraph
on the water, the metals, the flow and the history>.
Write no plan yet. Ask me the questions a new colleague would
ask in their first week, one at a time. After each answer,
say in one line what it changes, then ask the next question.
At least eight questions. When you know enough, say so,
summarize what you have learned in ten lines, and wait for me
to say go before you write any plan.

Attach: a paragraph on the loop in the prompt; nothing else until the questions are done.

Why it works: the questions come before the assumptions, so the plan is built on answers rather than on guesses that have to be undone later.
