Outputs

After the message is sent, this Tool step returns two values you can reference in later steps: Wire these outputs into a subsequent Slack - Update Message step to edit the same message in place — for example, to show progress as a multi-step task completes.
This pattern sends one status message at the start of a run, then edits it as each task completes.Send Message step — posts the initial checklist:
  • Message: Task progress:\n⬜ Step 1\n⬜ Step 2\n⬜ Step 3
  • Outputs: ts and channel are saved for use in later steps
Update Message step (after Step 1 completes):
  • Channel: reference the channel output from the Send Message step
  • Timestamp: reference the ts output from the Send Message step
  • Text: Task progress:\n✅ Step 1\n⬜ Step 2\n⬜ Step 3
Update Message step (after Step 2 completes):
  • Text: Task progress:\n✅ Step 1\n✅ Step 2\n⬜ Step 3
Each Update Message step edits the same original message rather than posting new replies, keeping the Slack channel tidy.
