Curator delete command

How can I know which command is being used in Curator to delete indexes.
Suppose User A has deleted indexes using a command rule of deleting after every 30 days. How will User B know what commands are being used by User A??

Thanks,

There is no way for this to be the case, at least not directly. User B may run show commands to see which indices are present, but would only be able to guess or infer what commands were used.

This is why it's best practices to have one client run curator commands.
