FYI, I’ve just tried using this Shortcut and I’m getting the error message below:
The operation couldn't be completed. (InterchangeCallbackErrorDomain error 0.)
EDIT: I got it working after changing the project name in the Shortcut from “Snippets” to a project that I have in my copy of Agenda. You said on Jan 2 that you updated the script to prompt for project name, but I’m guessing you didn’t edit your original post to include a link to the new script. (Annoyingly, any iCloud link to a Shortcut seems to only go to the original version of that shortcut, it won’t get you any subsequent updates.) I’ve gone ahead and added my own prompt, that version of the Shortcut is here: Shortcuts
