This seems wrong at least at two points:

1. The automatic assumption that any support of AI makes a contributor not read his contribution, not understand his contribution, and the whole thing ununderstandable to a degree which can not be remedied in the same way as hand written code is completely irrational. AI code can be bad. Manual code can be bad. I produced both kinds. Reasonable people read their code before submitting, or, say, try to put it in shape. Assuming people lose their reasonable minds by using an AI  summary of a local MR index is, sorry, ridiculous.

2. What you wrote basically means, that code can be trusted blindly once it was written by hand. This is but a joke.

Hi Dan,

thanks for bringing this up.

Now, I want to ask whether anyone sees any issue with merging AI-generated program code.
I think there are all sorts of issues, and I won't go into the broader issues regarding the copyright status of AI-generated code (which might contain copyrighted bits of training material), the environmental impact of AI data centers etc. Instead, I'll focus on the question of quality of code contributions, but these of course automatically pertain to how that quality gets assessed.
This is somewhat urgent in the sense that we have such an MR in draft, though of course we could delay it until there is certainty.  I just wouldn't want the uncertainty to last so long that a capable contributor gets frustrated and leaves.

To my knowledge (and I have been paying only minimal attention), the FSF views AI-assisted contributions to GNU projects as potentially problematic but has not established a policy.

As a reviewer, I strongly desire two things:

1. openness about the origin of the code I'm reviewing
2. accountability of the human submitter (not reviewers)
   for the code that is merged

For the MR that is in draft now, there were tells in the patch, but I had to ask the submitter twice before he confirmed that it was "AI-assisted."

In my opinion, LilyPond should only contain code that a human understands. It is essential that the creator of a MR understands their code, and it is desirable that a code reviewer understands the code as well (the latter, of course, depending very much on the time and generosity of people willing to do reviews). This is not just a question about AI contributions: It means that LilyPond also shouldn't contain human-written code of the "I added that line and then the problem somehow went away, knock on wood" type. It's of course hard to enforce this, but a thorough review where questions can be raised and must be dealt with makes it more probable.

To streamline this in the future, I propose configuring a template for default MR descriptions something like this:

    ##### Description

    <!-- Describe your motivation and your work briefly
    to orient reviewers.  If you have not described
    your commits well, go back and do that first. -->

    ##### Question

    What percentage of this work is AI-generated?  <!-- 0-100 -->

Do you think that would effectively address that specific concern?

Of course, since the number given will (according to your proposal) influence how the MR is dealt with, we depend on getting an honest answer to that question. I don't want to seem paranoid, but maybe it would be wise to add - somewhere in the CG - a statement along the lines of: Commits with non-disclosed AI-generated code get refused (or may get reverted later).

In the discussions of the current MR I noticed the term "AI-assisted". Maybe it would we a good idea to distinguish various kinds and degrees of AI assistance: IIUC, not every way of using an LLM during development leads to longer, coherent blocks of AI generated code.

Therefore, I suggest adopting a new policy: AI-generated program code does not automatically move forward without a human reviewer's acknowledgment.  It should be full acknowledgment, not, for example, "C++ LGTM; don't know about Scheme."

It would fall to the "patch meister" to help people follow this policy and to allow sensible exceptions, such as if a contributor with a good record vouches for the quality of his own AI-generated submission in an area where he has developed expertise.

I support this. This basically means that you either have to motivate reviewers to look at your code, or you have to build a reputation by smaller patches that both show and increase your familiarity with the codebase.
