WHAT IT DOES

What List_External_Event does on Files Com

AI agents call List_External_Event to retrieve information from Files Com without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why List_External_Event is rated Low

The tool performs a read-only query of external events from the Files.com platform. 'List' operations are inherently Read category as they retrieve data without side effects. The blast radius is minimal since no data is created, modified, or deleted, and no external systems are triggered.

From the tool's definition Tool name 'List_External_Event' and description 'List External Events' indicate a retrieval operation with no modification capability.
