  • Paste it in, tell the assistant who the summary is for, and ask for a specific format.
  • bullet points, one paragraph, or an executive brief.

Bad prompt: "Summarize this."

Good prompt: "Summarize this 40-page report for a CFO who has 90 seconds. Return: (1) the headline finding, (2) three numbers that matter, (3) one recommended action. Under 150 words."

The specificity is what makes the summary useful.
