AI agents call snow_get_event_queue to retrieve information from Serac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about event queue status and pending events. It has no side effects, does not modify data, does not execute external operations, and does not delete or move resources. It is a straightforward retrieval operation (Get) consistent with the Read category.
