You came here searching for an answer. The problem is you wanted one specific answer, one that validates your own stance. So now if someone gives you an answer that doesn't sit well with you, you will try to convince them that you're right anyway for whatever reason you want.

Discussing this seems useless.

fair point, but it is because the discussion drifted to legal while I wanted to discuss more "how do you feel about sharing your AI moat"

In terms of legal, f* no, I am not going to consider my tool adjustments as part of companies properties :)

We can discuss but I will stand my ground: my AI skills - even written on a disc - belongs to me. Same, if I go to car paint garage to have my paint fixed I am not expecting the painter will reveal his method to get the perfect color or give me his notes where he self-described "how to paint".

Before "AI era" we all had our own system scripts, manually crafted in bash/python, to make repeating task automated. And then it was never a question to share it: the scripts are the way how I configure/tune my computer and how I get advantage over other developers. The .cloude/.cursor directory is the same.
