Fix retries for Slack posting so finished work is not sent twice

You’re the ai / ml engineer. Your team is in the room. Printed Oct 13, 2026.

Slack retries are protecting task completion while duplicating completed updates.

The harness must recover from late tool responses without making colleagues clean up repeated messages.

Who you’d be doing this for

“I had three people ask whether the same update meant three separate changes.”

Ato Adekunle · Research Operations Manager

Coordinates internal research requests and depends on Slack updates to keep reviewers aligned.

What is at stake

Duplicate Slack posts now affect 3.8% of completed posting tasks. You must weigh fast recovery from real failures against the credibility lost when completed work repeats.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • task recovery vs duplicate outward actions
  • simple configuration vs action-aware state
  • release speed vs replayable evidence

Why Perplexity

Perplexity Computer turns research into actions across Slack, so a repeated post damages confidence in delegated work.
