Use a Slack reaction to coordinate browser work
A reaction can mark the moment to signal a browser workflow that another process should pick up.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Signal Event
Tool to signal a specific event to be received by other processes or sessions. use when you need real-time coordination across browser sessions after verifying session is active.
Why this helps
Coordination cues can get lost when the team relies on separate messages to tell browser processes that work is ready.
- Turn a designated reaction into a coordination signal.
- Keep the handoff cue attached to the original Slack message.
- Check for an active session before signaling.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anchor browser to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to signal a browser coordination event after a designated reaction is added to a Slack message.
- 3Describe the reaction meaning and the relevant active browser session in one plain-language instruction.
- 4Pick the Slack Message Reaction Added trigger, then choose the channel for run reports.
- 5Test by adding the designated reaction to a real coordination message for an active session.
Questions about this workflow
Does this signal without checking the session?
The prompt should direct Notis to verify the relevant session is active before using the signal action, which is intended for coordination across active sessions.
Does it act on every reaction?
Use the trigger's optional channel and emoji filters where available, and state the intended reaction in the prompt.
