Delete an item from the SABnzbd queue by its NZO ID. Optionally also deletes downloaded files.
AI agents call sabnzbd_delete_item to permanently remove resources in Homelab — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes data (queue items and optionally downloaded files) from the system. Deletion is inherently irreversible and destructive. The optional file deletion amplifies the risk. While the blast radius is somewhat contained to the SABnzbd service, the data loss is permanent, justifying the Destructive category and high severity.
From the tool's definition The tool name includes 'delete' and the description explicitly states it 'Delete[s] an item from the SABnzbd queue' and 'Optionally also deletes downloaded files.' Deletion of files and queue items cannot be undone.
