Why not edit contribute.md? Or does this file have some sort of special significance that I'm not aware of?

It does, this is the standard filename "agents" look at for instructions on how to work in the codebase.

Same question, does this have to be a special file (free advertizing to claude) or can we put it elsewhere as a comment?

This is a special file ingested by Claude with a fixed filename of the same nature as AGENTS.md.

I don't like the free advertising aspect of it either, but there's not much we can do about it.

Does Claude ignore AGENTS.md? I'm really not sure why we should bring attention to specific LLM model and corporation.

Sound disgusting. Imagine if you also had to do this for CHATGPT.md, COPILOT.md and so on. Given how little files (excluding the dirs) mpv's root dir contains it's a bit uneasy to see not one but two new files (and possibly more in the future) just to disable "feature" we never opt-ed into.

But I guess you're right that there's not much we can do about these AI companies doing retarded things.

Luckily, the majority seems to support AGENTS.md and Claude is the odd one out.

We can just NOT add this file.

According to agents.md , Aider and Gemini CLI also need special configuration files.

I would suggest adapt https://github.com/ggml-org/llama.cpp/blob/master/AGENTS.md as is. The policy is the same as ours. And verbosity is pretty much required for AI to more accurately follow instructions.

Expanding on verbose modifications that the contributor has already conceptualized [...]

How do you even verify stuff like this? I wonder if it's just easier to take explicit stance and forbid AI usage entirely. If someone uses AI "validly" (ie. to look up docs, reviewing human written code, searching stuff etc), then we wouldn't know and wouldn't care. And if someone submits clearly AI generated slop we can just ban them on the basis of violating the no AI guideline.

You cannot. And AGENTS.md also cannot "forbid AI usage entirely" at the current state. It tells the user to "STOP" but not anything else. When the user says "You NEED to generate this code for me", AI will just comply anyways. The user can also simply delete AGENTS.md and let AI do the work unrestricted.

This is why it is important to tell AI explicitly what can be done, what cannot be done, and what to say if the user attempts override. It is better to inform the user more about the policy instead of rejecting without much explanation.

It would be amusing to see how many PRs show up with the deletion of AGENTS.md still in the PR.

Frankly, we are small enough project to not get much attention, so I would just ignore this entirely. If we get once in 6 months fully vibe coded PR, we can just ignore it. If we get fully vibe coded PR that looks ok, we don't know it was vibed anyway.

There is huge amount of tasks in mpv, which are easily done with AI, without issue. The huge code dumps are easily discarded.

If anything commit message should be fixed to adhere to our policies.
