alt Hacker News> these are just bs to have people accept them, but is that actually the case?
I tried to outline that in my sibling comment[0], but I think the article also gives a good example in the "hidden searches" paragraph: There is really no good reason not to expose details about many of the builtin tools, or provide them as standalone services, other than protect their moat.
I don't think that "role confusion" attacks could be meaningful prevented by not showing reasoning traces. Prevention of reasoning traces is about as futile as prevention of system prompt leakage. And here you would just have to manage to exfiltrate a small number of reasoning traces per model family in order to distill the writing style of thinking traces.
