I read that too, but couldn't fathom what they meant. Still, I'm not sure what they mean by "prefix argument." And why does (shell-command "uuidgen" t) produces two outputs? For other readers, this is what they look like in *scratch*

(shell-command "uuidgen" t)
2827
b5da7e0a-84c0-4db8-91f3-871b681f3022

(org-id-uuid)
"0bb7a4e1-9fc2-4428-b8de-a2d9ef5c56ab"

Also, does anyone know how I could have done this by "advise"-ing a function in org-mode tempo templates? I could never figure out what function was actually handling the <...-TAB.

Yes, thanks. That substring was a bad copy. Any insight why the (shell-command "uuidgen" t) wasn't working?

I hadn't looked at it yet, but the documentation for ="" gives the answer:

Execute string COMMAND in inferior shell; display output, if any.
With prefix argument, insert the COMMAND’s output at point.

So this function does not return a string that can be concatenated with others, it actually inserts the output in the buffer, so it's not guaranteed it will land where you need it.

To have the output of the command returned as a string, I think you should use =shell-command-to-string=.
