If you go to a coffee shop and ask extra ice, less sugar, more vanilla - did you make the coffee or the barista make the coffe and you just gave some requests to him. Using an LLM is far more similar to ordering coffee from a barista than it is to actually making the coffee. Of course the barista didn’t make the seeds, the milk etc. This is not an exact lawyerly statement.
But intuitively, you didn’t make anything when Claude Code writes all your code.
Because it's a common experience of folks using LLMs to code (and other activities) that experts get better results than non-experts.
So it definitely suggests that the human is part of the making process, not just the recipient of the finished product as in your coffee example.
You are right, I did not solve the problem "how do I need to layout the editor so the chords appear directly above the correct bar".
I definitely solved the problem "I don't have a tool to quickly create guitar tabulature that I can use on my iPad"
