A polished draft is useful only if it serves the task and preserves the evidence. The same tool can help with one job and fail at another; method, task difficulty, source quality and model capability all matter.
Start with a modest deliverable you can inspect: an event notice, a short update or a comparison of supplied options. Decide what it must achieve and how you will check it before asking for a draft.
The examples below let you practise judging a draft against its sources without opening another service or sharing real work information.
