Script adding too many new works

[dosoe]

Hi all,
I recently encountered a user that used one of the scripts to automatically create lots of new works: https://musicbrainz.org/edit/112649307
The script leaves the following trace in the edit note:

—
MusicBrainz: Batch-add "performance of" relationships 2023.7.2
Relate to new work using recording title

The problem is that this script doesn't check if a work is already attached, or if a work already exists. This has led to countless new useless works added, with near-identical titles or to recordings where the correct work is already attached. Is there a way to give a warning when using the script, or at least check if a work is already linked before creating a new one? Also, the works it creates do not have any properties/relationships attached to them, making them pretty useless. Is this a case of lack of discernment of the user, or could the script be improved to make it less prone to this kind of behavior?
I haven't used the script, I just cleared up the mess when a user went nuts with it.
Thanks,
Dorian
