Start each new channel with a file readiness check
New project channel, same reliable start. Have Notis inspect the designated onboarding file and return its properties when the channel is created.
Trigger
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Action
Get File Properties
Tool to retrieve properties of a file. Attempts multiple Encodian Filer endpoints and fallbacks.
Why this helps
New channels often launch before anyone confirms that the shared starter document is present and usable.
- Add a lightweight file check to new channel setup.
- Spot missing or unexpected document properties early.
- Avoid a separate manual checklist for each channel.
Setup
Build it in a few focused steps.
- 1Connect Slack and Encodian to Notis once in the portal.
- 2Create an automation with one plain-language prompt naming the onboarding file location to inspect and the properties to report.
- 3Pick the New Channel Created trigger and choose where run reports should appear.
- 4Test by creating a real test channel with the designated file available.
Questions about this workflow
Will this automatically create an onboarding document?
No. The selected Encodian action retrieves properties for a file; it does not create one.
What if a new channel has no matching file?
Tell Notis in the prompt to report that the designated file could not be checked, rather than implying it is ready.
