Why this helps
Teams can lose track of whether a cleanup request still stands after a decision signal changes.
- Bring attention back to a changed cleanup signal.
- Reduce the risk of forgotten maintenance decisions.
- Keep the action tied to explicit team context.
Setup
Build it in a few focused steps.
- 1Connect Slack and Expofp to Notis once in the portal.
- 2Create an automation through the portal or ask Notis in plain language.
- 3Write one prompt instructing Notis to remove the identified category only when the message context confirms the final cleanup decision after the reaction is removed.
- 4Choose the Slack reaction-removed trigger and run-report channel, then test with one real reconsidered decision.
Questions about this workflow
