About this exercise

Start with the line "SEAT CREDIT - Blue Fern". Then write three lines starting "Per seat:", "Credit:" and "Applied to:" showing the arithmetic. The credit is account credit on the next invoice, not a refund to the card. Plain text, under 50 words.

Common mistakes when you ask AI for this

  • Giving the full month. The AI credits $36. Try: Say: "Prorate by the 18 remaining days of 30."
  • Refunding to the card. The AI says the credit goes back to the card. Try: Say: "Account credit on the next invoice only."
  • Missing the title. The AI starts with the math. Try: Quote the title.
  • Getting markdown back. AI adds bold and headings by default, which show up as stray symbols where this is pasted. Try: Say "plain text, no bold, no headings, no asterisks".
  • Trusting the AI to count words. AI is bad at counting and usually runs long, so a vague "keep it short" lands well over the limit. Try: Cap each part instead of the total, for example "each line under 15 words".

What a strong prompt includes

  • Quotes the title
  • Names the three lines
  • Asks to show the arithmetic
  • Asks for plain text
  • Sets a length limit
