Start with the outcome
Name what you want to have at the end. A useful request describes the result clearly enough that you can tell whether it succeeded.
Give relevant context
Include the intended audience, source material, and purpose. Relevant context helps a tool make fewer guesses. Extra information that has no bearing on the task can obscure what matters.
Make the constraints explicit
State the format, length, tone, and facts that must be preserved. Say which decisions the tool can make and which need your input.
Define how you will check it
Review factual claims, compare the output with the source, and check that it meets the actual purpose. A well-written response can still contain errors.
