AI agents call iot_fleet_list to retrieve information from Ruflo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about IoT fleets without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval function with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'iot_fleet_list' and description 'List all fleets' indicate a retrieval operation with no side effects. The verb 'list' is explicitly enumerated in the Read category definition.
