When a commute concern is buried in chat, remembering to check for a service disruption can be easy to miss.
- Use a lightweight reaction to signal that a travel detail needs attention.
- Bring service information into the workflow without opening another tool.
- Create a clear prompt for checking advisories on a specific concern.

- 2Create an automation in the portal or ask Notis to check BART advisories when you react to a travel message.
- 3Write one plain-language instruction saying to retrieve current advisories related to the message.
- 4Select the Slack message reaction trigger and choose where run reports should appear.
- 5Test by adding the chosen reaction to a real travel-related Slack message.
