There are no destructive operations, no code execution, no data modification, and no financial transactions involved. The blast radius of misuse is minimal — an agent could repeatedly query wars or access unnecessary data, but cannot harm the game state or commit resources. This is a straightforward Read operation.
From the tool's definition The tool description explicitly states 'Get an individual CWL war by warTag' — this is a retrieval operation with no side effects. It fetches existing data from the Clash of Clans API.
