Get full details of a calendar event
AI agents call get_event to retrieve information from Mail Cal Drive without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves calendar event information with no side effects. It queries existing data and returns details without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker could only access calendar data they have permission to view, not alter it or cause financial harm.
From the tool's definition Tool name 'get_event' and description 'Get full details of a calendar event' indicate data retrieval without modification. The verb 'Get' and the absence of any language suggesting mutation, deletion, or execution confirms this is a read-only operation.
