Why this helps
New project setup can scatter essential links and leave nobody sure whether the starting page works.
- Add a small check to an otherwise busy project kickoff.
- Keep the page review connected to the new channel's setup.
- Catch obvious access or loading issues early.
Setup
Build it in a few focused steps.
- 1Connect Slack and Browserless to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Write one instruction asking Notis to watch a newly created project channel for an onboarding URL and safely check whether the page loads.
- 4Select the Slack new channel created trigger and a channel for run reports.
- 5Test with a new project channel and one accessible onboarding URL.
Questions about this workflow

The prompt should describe where the URL will appear, such as a setup message in the new channel.
Does it update the onboarding page?
