The One-Paragraph Brief
Reach for this when you know what you want done but not how to explain it to a machine.
I'm handing you a whole task, not a single question. Here's the brief. What done looks like: [describe the finished thing, e.g. a short list of three good options with prices]. What I'm working with: [paste your details, budget, deadline, anything relevant]. What matters most to me: [the one or two things you really care about]. Before you start, tell me in two lines how you'll go about it, so I can correct you early.
The order matters: outcome first, then your stuff, then what you care about. It's how you'd brief a capable friend, and it stops the AI from solving the wrong problem beautifully.
