Scripting "Add Link..."

I think there is an ambiguity in this question, which perhaps other people will face as well: are you asking

1. can you perform the “add link” option using AppleScript?
2. can you use “add link” to link to AppleScript code displayed in a document?

If it’s #2, it would be useful to know what kind of document contains the AppleScript code you would like to link to. Is it, for example, a Markdown document containing a code block with AppleScript inside the code block?
