Hmm... It's an interesting question: at what point, in a conversation, document, image, story, does human authorship end and AI authorship begin? How would you know? Is it a tell tale or is it advertising?

> Unless you literally vibe coded it, Claude is just a tool.

Stop with the selective bias, two are birds of the same feather, they are using a "tool" to write the code for them from whatever (questionable) mashed up source they are trained from, in the same way someone is using AI as a "tool" to fabricate their curriculum and cheat a job

> The intent isn't to disclose that AI was used in creating the code, the intent is to advertise the AI product

That is a wild mental gymnastic to justify dishonestly submitting code you didn't write (or own) as yours. It has nothing to do with advertisement but proper attribution, you know it.
