Two words left the tool guessing. Answer what a colleague would have asked, and the first draft is nearly right.
Who it's for
What good looks like
What to leave out
One example
Dispatch wants a list of tomorrow's early collections every afternoon, drafted by the tool from the booking export. Which brief gets you something usable first time?
"For the dispatch lead, read at 7 a.m. on a phone. One line per collection: time, depot, van. Leave out anything after 10 a.m. and cancelled bookings. Example: 07:30, depot B, van 2."
"Make a clear, well-organised and accurate list of tomorrow's early collections. Be thorough."
"You are a logistics expert with twenty years' experience. List tomorrow's early collections."
The first brief answers all four questions: the dispatch lead at 7 a.m. on a phone, one line per collection with three fields, nothing after 10 a.m. or cancelled, and an example line to copy. The second asks for quality without saying what quality looks like, so the tool guesses. The third gives the tool a job title, which still tells it nothing about who reads the list, what goes in each line or what to leave out.
