I agree on the face of it, but it's just as unenforceable as the Assisted-by tag was. :( My own recent commit logs are, like the code, a combination of work from me and the LLM. I trim and edit and reorganize and add/remove stuff all the time (code or commit log). And all the while, tweaking its rules for how to write prose, so I do less and less editing. (And maybe my commit logs are now too verbose? I'm not sure; I've regularly been told I was too terse before, so hopefully there will be a balance found.) And as far as spotting this kind of thing, I've already failed the Reverse Turing Test[1], where I thought some of Lorenzo's (justifiably) verbose commit logs were all LLM generated, so the inflection point for clearly distinguishing is here or fast approaching. -Kees [1] https://lore.kernel.org/all/202609150943.000EC9277@keescook/ -- Kees Cook
