获取某天的压力数据（全天压力均值、峰值等）
AI agents call get_stress to retrieve information from Garmin Connect China MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical stress measurements from a health tracking service. It performs a read-only query of user health metrics with no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could only access existing stress data the user is already entitled to view. No financial, destructive, or system-level impacts are possible.
From the tool's definition Tool name 'get_stress' and description '获取某天的压力数据（全天压力均值、峰值等）' (retrieve daily stress data including average and peak values) indicate data retrieval with no modification or side effects.
