Q: Are there libraries of Zerowork Taskbots that are already written, that I can simply import and customize ...
rather than create everything from scratch?

The subflow-library, which I mentioned I my original answer (see below), has grown to over 50 free-for-all TaskBot templates. đĽ

Recently, our community started a subflow-library on our Discord where you can pull a copy of any TaskBot shared there. The initiative is recent. There are about 15 subflows at the moment, but the amount is growing fast.
There is also a template website here: https://automatorsanonymous.club/ started by one of ZeroWork's most advanced and helpful users. (Note: Most templates are paid but of premium quality. We do not get any commission).
