What zernio_send_broadcast does on Zernio
AI agents invoke zernio_send_broadcast to trigger actions in Zernio. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why zernio_send_broadcast is rated High
Sending a broadcast triggers an immediate external operation — dispatching messages to potentially large audiences across social/messaging platforms. This is an Execute-category action (triggering external operations), with high severity because misuse could result in mass unsolicited messages being sent to many recipients at once, with significant reputational and operational blast radius.
