Recheck the context when a research flag changes
When someone removes a research reaction, use that change as a prompt to check whether public context has shifted before closing the loop.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Search
Performs a web search using the exa engine, useful for queries requiring advanced filtering, specific content categories, or ai-optimized prompting.
Why this helps
Research priorities can change, but teams may not know whether a topic became irrelevant or simply needs a refreshed check.
- Turn a changed signal into a quick context check.
- Find public developments that may affect the topic.
- Help the team close or reprioritize an open research thread.
Setup
Build it in a few focused steps.
- 1Connect Slack and Exa to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to search for recent public context when a research reaction is removed from a Slack message.
- 3Use one plain-language instruction to identify the message topic and return relevant current sources for review.
- 4Select Message Reaction Removed as the trigger, optionally filter to the research emoji, and choose a report channel.
- 5Test by removing the agreed reaction from a message with a clear topic.
Questions about this workflow
Does removing a reaction prove a topic is no longer important?
No. It is only a signal to check context; the team decides whether to close or continue the research.
Can this find recent information?
Exa Search can search the web; ask for current public sources and review publication dates.
