What iot_fleet_delete does on Claude Flow
AI agents call iot_fleet_delete to permanently remove resources in Claude Flow, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why iot_fleet_delete is rated Critical
The tool performs a destructive action that cannot be undone: deleting an entire fleet of IoT devices or their configuration. Even though it operates on a fleet abstraction rather than individual records, the deletion is irreversible and affects multiple resources. This qualifies as Destructive rather than Write because deletion is not reversible.
From the tool's definition Tool name contains 'delete' and description states 'Delete a fleet' — this is an irreversible deletion operation.
