AI agents call maps_weather to retrieve information from 高德地图 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 weather data based on input parameters (city name or adcode). It performs a read-only lookup operation without modifying, deleting, or executing any code. The operation is purely informational and has no blast radius if misused by an AI agent—it simply returns weather information.
From the tool's definition Tool name 'maps_weather' and description '根据城市名称或者标准adcode查询指定城市的天气' (query weather for specified city by city name or standard adcode) indicate a data retrieval operation with no side effects.
