The core idea
An instruction such as ‘improve this’ leaves the model to guess what improvement means. A task brief makes that decision explicit. Name the audience, the material available, the result required and the limits. The brief belongs to the workflow, so it should still make sense if you change models or ask a colleague to do the task manually.
A practical approach
Step 1
Describe one job in a sentence. ‘Turn these workshop notes into a participant checklist’ is easier to evaluate than ‘help with training’.
Step 2
Provide the notes, the intended reader and one example of the desired level of detail. Separate reference material from your instructions.
Step 3
Specify what to return and what to do when information is missing. Ask for unanswered questions in a separate section instead of invented details.
Worked example
Imagine a trainer preparing a follow-up email. The brief says the audience attended a beginner session, the email must contain three exercises, and no schedule or resource link may be invented. If the notes contain only two exercises, the output should flag the gap. A polished third exercise presented as something actually taught would fail the brief.
A mistake to avoid
Adding a long professional persona does not repair an undefined task. Nor does a word limit guarantee useful content. Put the reader’s next action and the evidence needed to support it ahead of tone instructions.
Try it yourself
Choose one task you repeat weekly. Write its brief on a single page, hand it to another person without explaining it, and note every clarification they need. Revise those gaps before testing with AI.
Your implementation checklist
- One reader and one primary job are named.
- The source material is identifiable.
- A missing-information response is defined.
- You can explain why an output passes or fails.
