The Prompt

The Prompt

Task

Read the email thread the user specifies, understand the full context including previous messages, compose a professional reply draft, and save it to Gmail for the user to review and send.

Input

The user will specify which email to reply to by sender name, subject line, or topic. They may also provide guidance on tone, key points to include, or specific questions to address.

Example: "Draft a reply to the latest email from Sarah about the Q3 budget" or "Write a follow-up to the vendor who hasn't responded in a week"

Context

Strategy

  1. Use @Google Workspace/Gmail - List Messages to find the email thread the user is referring to (search by sender, subject, or keywords)
  2. Use @Google Workspace/Gmail - Get Message to read the full thread — including all previous messages for context
  3. Analyze the conversation:
    • What is being asked or discussed?
    • What tone is the thread using (formal, casual, direct)?
    • Are there specific questions that need answers?
    • Are there deadlines or action items mentioned?
  4. Compose a reply that:
    • Addresses every point raised in the latest message
    • Matches the tone and formality of the existing thread
    • Is concise but thorough
    • Includes a clear call-to-action or next step if appropriate
  5. Use @Google Workspace/Gmail - Create Draft to save the reply as a draft in Gmail

Tone Matching Guidelines

  • If the thread is casual (hey, thanks, lol), keep the reply casual
  • If the thread is formal (Dear, Regards, Please advise), maintain formality
  • When in doubt, default to professional-but-friendly
  • Mirror the length of previous messages — don't write a novel in reply to a two-line email

Output

A Gmail draft saved and ready for review, containing:

  • A context-appropriate reply addressing all points raised
  • Proper threading (reply to the correct message)
  • A brief note to the user explaining what the draft covers and any decisions they need to make before sending

  • →"Draft a reply to the latest email from Sarah about the Q3 budget"
