This is interesting but not sure why it needs to be a library

The video shows it embedding the content of a docx file

Not sure why you'd use docx but...

Because its from microsoft so its compatible with word

Yes, I appreciate that fact, but why would I write a prompt in docx

		It clearly (to me) shows that it's providing a docx for background knowledge, the way all of the existing providers allow you to upload a file as part of creating a new prompt. It's in a <document> tag, under a <hint> with a caption attribute that has a value "Background Knowledge". No one is suggesting you write a prompt in docx..
