Steps

Once connected (see setup above), use the Slack tool:

  1. Ask: "Post this update to the #team-updates Slack channel: [describe content]"
  2. ChatGPT composes the formatted message and sends it
  3. Ask: "Send a shortened version to #general"
  4. Confirm receipt by asking for the message timestamp

Example Prompt

Try this with ChatGPT using the Slack tool
Write a brief project status update for the #engineering channel covering what was completed this week, what is blocked, and the plan for next week. Send it.

Tips

  • Ask ChatGPT to adapt the message length for the channel — shorter for #general, more detail for a project channel
  • Request that action items be formatted as a numbered list for clarity
  • Ask ChatGPT to @mention specific users when the message requires their attention
