Describing the style or rules you want is hard. Showing a couple of examples is easy, and models copy patterns very well. This is called few-shot prompting.
Classification with examples
“`text
Classify each expense into Travel, Office, Meals or Other.
“Uber to client office” -> Travel
“Printer cartridge” -> Office
Now classify: “Team lunch”, “Train ticket Delhi-Jaipur”, “Stapler”, “Gift for client”
“`
Two examples define the format and the categories better than a paragraph of rules.
Copying your style
Paste two emails or reports you wrote that you like, then: “Write a reply to the message below in the same style and length.” The result sounds like you, not like a generic AI.
Templates
“`text
Write a payment reminder.
Customer: [CUSTOMER] Invoice: [INVOICE] Amount: [AMOUNT] Days overdue: [DAYS]
Tone: [friendly/firm]. Under 120 words.
“`
Save templates for tasks you repeat; fill the brackets each time (Lesson 8 builds a library).
💡 Use varied examples. If all your examples are short or all are positive, the model will assume every answer should be short or positive.
