WHAT IT DOES

What disk_smart_test_list does on Nasbridge

AI agents call disk_smart_test_list to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why disk_smart_test_list is rated Low

This tool retrieves and displays existing SMART test result data from TrueNAS storage devices. It performs a read-only query operation with no side effects, no data modification, and no irreversible actions. The optional filtering parameter does not change the non-destructive nature of the operation. Severity is low as misuse would only expose diagnostic information already available on the system.

From the tool's definition Tool name includes 'list' and description states 'List SMART test results'. The verb 'list' indicates data retrieval with optional filtering by disk name, with no modification or deletion of data.
