Write a reusable prompt and compare its results against a small checklist.
Start with the outcome
A useful prompt begins with the job you need done. First, describe the reader and the decision your output should support.
The task boundary keeps the request manageable. For example, ask for three options with trade-offs before asking for a complete strategy.
A success check makes the result easier to judge. Specify which facts, sections, or unresolved questions must appear.
Choose the right context
Relevant context includes the facts and constraints needed for this particular task. However, a large pile of documents can hide the useful details.
Clear instructions explain what to produce, while source material provides evidence. Label those parts separately so their roles remain visible.
An example can show the expected shape of an answer. Use fictional details, and make clear which features should carry across.
Worked example: an editorial brief
Fictional scenario: an editor asks, “Write something interesting about AI.” The answer sounds polished, but lacks a defined audience and purpose.
A better request: “Draft a 150-word brief for small-business owners using only the supplied notes.” Then add: “Include one opportunity, one limitation, and one unresolved question.”
The review step compares every factual sentence with the notes. If the draft invents a statistic, remove it and clarify the evidence boundary.
Improve one variable at a time
A controlled comparison uses the same input with two prompt versions. First change the output format, then inspect whether the required information survives.
Repeated examples reveal whether an improvement carries beyond one convenient case. Include a sparse input where the correct answer admits missing information.
A prompt limit matters as much as a prompt technique. Better wording cannot supply missing evidence or guarantee a correct answer.
Try it yourself
Your exercise is to create a reusable briefing prompt with five fields. Include task, audience, evidence, format, and quality checks.
A stress test uses notes containing an unresolved contradiction. Ask the model to flag the conflict instead of silently choosing a convenient answer.
Success looks like a prompt another person can reuse with different notes. Keep a before-and-after comparison and record one remaining limitation.
What to carry forward
Write a reusable prompt and compare its results against a small checklist.
Show your reasoning with the exercise above. Keep the evidence, the decision, and the remaining uncertainty together.
