Queries free/busy information for one or more calendars within a specified time range.
AI agents call query_calendar_freebusy to retrieve information from Pointsyeah without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves calendar availability status (free/busy times). It performs a passive query with no ability to modify, delete, or execute actions. The worst-case misuse (e.g., gathering scheduling information about targets) is low-severity reconnaissance with limited blast radius.
From the tool's definition Tool name is 'query_calendar_freebusy' and description states it 'Queries free/busy information' — a read-only retrieval operation with no data modification or side effects.
