Get the Cloud Resource Name (CRN) of the currently active instance.
AI agents call active_instance_info_tool to retrieve information from Qiskit Gym 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 metadata about the currently active instance (its Cloud Resource Name). It performs a query/lookup operation with no data modification, creation, deletion, or execution of external operations. The information returned is configuration/status data. This is a straightforward Read operation with minimal risk if misused by an AI agent.
From the tool's definition Tool description: 'Get the Cloud Resource Name (CRN) of the currently active instance.' The verb 'Get' indicates a retrieval operation with no side effects.
