I've noticed this as well. "Now you should stop X and go do Y" is a phrase I see repeated a lot. Claude seems primed to instruct me to stop using it.
glm and kimi in particular, they can't stop writing... seriously very eager to please. always finishing with fireworks emoji and saying how pleased it is with the test working.
i have to say to write less documentation and simplify their code.
You need to train them on a special "stop token" to get them to act more human. (Whether explicitly in post-training or with system prompt hacks.)
This isn't a general solution to the problem and likely there will never be one.
