- 3Write one plain-language instruction to fetch recent Exist correlations when a reaction is removed and return a short context-review prompt.
- 4Choose the Slack reaction-removed trigger and the channel for run reports.
- 5Test by removing a reaction from one relevant message.
Questions about this workflow
Does reaction removal always mean disagreement?
No. Treat it only as a cue to review context, not as evidence of a person's intent.
Can I narrow which reaction matters?
Describe the relevant cue in the prompt and use available trigger filtering if desired.
