Write the prompt you would actually use for the situation below and score it. The move behind this lesson, with a worked example, opens after your first score. You will remember it better for having tried.

Your turn

You're a painter who charges by the room plus extra for high ceilings and a fixed trip fee. Write a prompt that turns those rules into a calculator where you enter the room count and get a price on the spot.

Remember: the AI sees only your prompt โ€” not this page. If the situation isn't in your prompt, it doesn't exist.
