Get detailed pool status with VDEV topology and error counts.
AI agents call get_pool_status to retrieve information from Truenas Ws without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries storage pool status information (topology, error counts) but does not create, modify, delete, or execute any operations. It is a passive information-gathering function with no destructive or side effects, making it a Read category risk with low severity.
From the tool's definition Tool name 'get_pool_status' and description 'Get detailed pool status with VDEV topology and error counts' indicate a read-only query operation that retrieves storage pool information without modification or side effects.
