What snow_emergency_broadcast does on Serac
AI agents use snow_emergency_broadcast to create or update resources in Serac, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Serac environment.
Why snow_emergency_broadcast is rated Medium
This tool sends notifications to all users or specific groups, which is a Write operation (creating/sending messages). The blast radius is high because a misconfigured or malicious invocation could spam every user in the organization with a false emergency alert, causing panic, operational disruption, or loss of trust — but it does not irreversibly delete data or move money.
