Delete a custom format from Sonarr by name. Also removes its score from all quality profiles automatically.
AI agents call sonarr_delete_custom_format 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 permanently deletes a custom format configuration and cascades the removal to all quality profiles, which cannot be undone. The plural 'profiles' indicates a wide blast radius (affects multiple quality profiles). While not as critical as data loss, deletion of system configurations that affect downstream quality rules is a destructive operation.
From the tool's definition Tool description explicitly uses 'Delete a custom format from Sonarr by name' and 'removes its score from all quality profiles automatically' — these are irreversible operations that modify multiple system configurations.
