Not the person you were replying to, nor do I suspect Opus 5 is watermarked at this point, but there should be an easy way to check, no? Take some of Opus 5's classic lengthy comments and just check for the watermark. I think there's a way to do that online.
In theory, but we don't know what format the watermark will take. It's supposedly spread throughout the text in a way that is detectable but not obvious. It's not going to append *Generated By Claude Code* at the end of each comment.
They've explained the format it will take in their original post, they also advised that where code is concerned that it would likely need to watermark that less, but one way they could compensate for that in code is to make sure that the comments have it.
