Why this helps

Reaction changes can erase useful visibility into what needed attention.

  • Preserve useful context
  • Clarify current status
  • Reduce lost follow-up

Setup

Build it in a few focused steps.

  • 1Connect Slackbot and DeepSeek once in Notis.
  • 2Create an automation named Reaction context recovery.
  • 3Describe that a message with a removed reaction should be restated with context, likely status, and any remaining action.
  • 4Pick the Message Reaction Removed trigger.
  • 5Choose the report destination, then test by removing one reaction.

Questions about this workflow

Can it know the previous reaction?

Only if that context is included by the event or supplied in the instruction.

Can it recommend whether to restore the reaction?

Yes. Ask it to recommend that when the available context supports it.
