Auto-Archive Slack Channels When Tasks Complete
Your Asana task moves to Done. The temporary Slack channel closes automatically. No clutter, full history preserved, clean workspace.
Trigger
Task Moved to Section
Triggers when a task is moved to a section in a project.
Action
Close conversation channel
Closes a slack direct message (dm) or multi-person direct message (mpdm) channel, removing it from the user's sidebar without deleting history; this action affects only the calling user's view.
Why this helps
Slack workspace sprawl overwhelms neurodivergent founders. Temporary project channels pile up, cluttering the sidebar and creating decision fatigue about which channel is active.
- Automatic cleanup: Completed tasks trigger channel closure, keeping your workspace tidy.
- Reduced sidebar clutter: Closed channels disappear from the sidebar, so your active work is more visible.
- History preserved: Closing a channel doesn't delete messages; they're archived and searchable.
- Prevents context loss: Even though the channel is closed, the conversation is still there if needed later.
Setup
Build it in a few focused steps.
- 1Connect Asana and Slack to Notis.
- 2Tell Notis: 'When a task in [Project] is marked Done, close the related Slack channel.'
- 3Notis asks which Asana section marks completion (usually 'Done' or 'Completed').
- 4Select 'Task Moved to Section' as your trigger.
- 5Test by moving a task to your completion section; the related Slack channel should close.
Questions about this workflow
What if the channel is still being used after the task is completed?
Notis closes the channel regardless. Team members can reopen it from archives if needed, or you can exclude channels that are still active.
Can I choose which channels to auto-archive?
Yes. You can configure Notis to archive only channels matching certain naming patterns or tags.
Are messages deleted when a channel closes?
No. Slack archives the channel, preserving all messages and files. The channel is read-only and searchable but removed from the active sidebar.
