About this exercise

Announce the new expense approval rule to your team in an email: plain text, subject line first, exactly 4 sentences in the body, under 90 words. Sentence 1 states the rule and the start date, sentence 2 gives the dollar thresholds, sentence 3 says what does not change, sentence 4 says where to ask. Use only the final policy.

Common mistakes when you ask AI for this

  • Old thresholds. The AI uses $300 and Jan 6. Try: Say: "Final policy: $500 and Dec 2."
  • Wrong sentence count. The AI writes a long email. Try: Say: "Exactly four sentences after the subject line."
  • Mentioning the card. The AI includes the card idea. Try: Say: "Don't mention the corporate card."
  • Markdown. The AI bolds amounts. Try: Say: "Plain text."
  • Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each sentence: "each under 22 words."
  • Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each part instead, for example: "each line under 12 words."
