Retire a project channel when its work closes
When a dedicated workstream is done, clear the active workspace while keeping its history available.
Trigger
Task Updated
Triggers when an existing task is updated in a Google Tasks list. This trigger monitors a specific task list and fires when tasks are modified.
Action
Archive a Slack conversation
Archives a slack conversation by its id, rendering it read-only and hidden while retaining history, ideal for cleaning up inactive channels; be aware that some channels (like #general or certain dms) cannot be archived and this may impact connected integrations.
Why this helps
Completed efforts can leave channels that look active and compete for attention long after the work ends.
- Reduce visual clutter from finished workspaces.
- Keep archived project history available for reference.
- Make active channels easier to scan.
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 conversationally.
- 3Give Notis one precise instruction to archive only the dedicated Slack channel when its associated task is marked complete.
- 4Select Task Updated as the trigger and choose a channel for run reports.
- 5Test with a non-critical project channel and confirm that the correct channel is archived.
Questions about this workflow
Can this action be undone?
Archiving makes a conversation read-only and hidden while retaining its history. Verify the target carefully before using it.
Should every completed task archive a channel?
No. Limit the prompt to tasks associated with dedicated project channels and test the criteria first.
