Delete one of your shortened URLs by slug.
AI agents call delete_url to permanently remove resources in Url Shortener — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a shortened URL record from the system. Deletion is an irreversible operation that cannot be undone—once a short URL is deleted, it ceases to function and the mapping is lost. This matches the Destructive category definition.
From the tool's definition Tool name 'delete_url' combined with description 'Delete one of your shortened URLs by slug' explicitly indicates irreversible deletion of data.
