Write a Prompt You Can Reuse
Write a prompt with a role, a task, constraints and an example, test it on five real inputs, improve it one change at a time, and tell an unclear instruction from missing information, so a weekly task gives the same clean result every time.
Outcome: One saved prompt improved across three revisions on the same five inputs, with a one-line note per revision, which passes when a colleague can see what each change did and every missing field reads "not stated" instead of a guess.
