Make task completion visible in Slack
Let a small signal mark progress where the work was discussed, without writing another status update.
Trigger
Task Details Changed
Triggers when a specific task's details change. This trigger monitors a single Google Task and fires when any of its details (title, notes, status, due date, completion, position) are modified.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Finished work may stay invisible in the conversation where teammates are waiting for it.
- Signal progress in the conversation tied to the work.
- Avoid composing a separate completion note.
- Make follow-through easier for collaborators to spot.
Setup
Build it in a few focused steps.
- 1Connect Google Tasks and Slack to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to set it up conversationally.
- 3Give Notis one instruction to react to the related Slack message when a task is marked complete, specifying a suitable reaction and how to identify the message.
- 4Select Task Details Changed as the trigger and choose a run-report channel.
- 5Complete a test task linked to a known Slack conversation and confirm the reaction is appropriate.
Questions about this workflow
Can the automation find the right Slack message?
Explain in the prompt how the related conversation can be recognized. Test with a clear example before relying on it for routine updates.
Does the reaction replace a written update?
It adds a lightweight progress signal. Use a different workflow when teammates need details or context.
