Get a patient
AI agents call get_patient_whoop_activity_data to retrieve information from Intelligent Medical Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves patient WHOOP activity data (biometrics/physiological data) without modifying or deleting it. It is a Read operation. Severity is medium because patient medical data is sensitive and could inform harmful decisions if an AI agent retrieves unauthorized records, but the tool itself only queries existing data with no direct destructive capability.
From the tool's definition Tool name contains 'get_patient' and description states 'Get a patient'; sibling tools (get_patient_overview, get_patient_visits, get_patient_whoop_journal_data, etc.) are all read-only data retrieval operations.
