AI agents call events_of_today to retrieve information from Tick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves scheduled events/tasks for a specific day. It performs a read-only operation that does not create, modify, delete, or execute any actions. The retrieval of calendar or task data carries minimal risk as it simply surfaces information already owned by the user.
From the tool's definition Tool description states 'Return timed scheduled items for a given local day.' The verb 'return' indicates data retrieval with no modification or side effects.
