Key point
One idea
Do not only explain the task. Show the model a few inputs and the kind of answer you expect.
Your examples become a mini training signal inside the prompt. Your edge cases show where the prompt must not break.
Why examples help
A prompt like “summarise this complaint” can produce many styles. One model may write a polite email. Another may write a long paragraph. A third may miss the real issue.
Examples reduce guessing. They show tone, level of detail, and what to ignore. This matters in a demo because judges and users will try messy inputs, not only clean ones.
