Why this helps
Cleanup decisions often stall when the action is separate from the conversation where the team agreed.
- Connect an approval signal to a clear cleanup action.
- Reduce lingering outdated categories.
- Make small maintenance tasks easier to finish.
Setup
Build it in a few focused steps.
- 1Connect Slack and Expofp to Notis once in the portal.
- 2Create the automation in the portal or ask Notis conversationally.
- 3Write a single prompt requiring the designated reaction and an explicit decision before removing the identified Expofp category.
- 4Select the Slack reaction-added trigger and run-report channel, then test with one real cleanup approval.
Questions about this workflow
Can a reaction alone identify the category?
The context must clearly identify the category to remove; the action requires its category ID.
Can this be used for uncertain cleanup suggestions?
Set the prompt to act only on a clear decision, not a tentative suggestion.
