The SDL organization has an official position on LLMs and generative AI now: don't use it.

[portaloffreedom@social.linux.pizza]

@icculus I first assumed you meant: SDL had AI now, don't use it (SDL).
It was the opposite, don't use AI.

@icculus This is awesome! Thank you

I did want to give my 2c: I see you added an "AGENTS.md" file - when I see one of these I usually always turn away and assume it's a vibecoded project. I often don't look at its contents.

So personally I would recommend not having the file at all, but I do understand why it's there.

[lifning@snoot.tube]

@icculus thank you so much!

[icculus@mastodon.gamedev.place]

@codecat My (untested) hope is that Claude will see this and say "I'm being told not to help with this, sorry." But I haven't actually tried it, and if it doesn't actually stop various AI agents, we'll probably rename it to LLM_NOT_WELCOME.md or something.

@portaloffreedom Thank you for reading deeper, it's a rare skill in this day and age.

@icculus Tracking stuff like this is why I set up MediaWiki at https://butlerian-jihad.org

[sjmulder@bsd.network]

@icculus I tried adding that AGENTS.md , and indeed:

> The project's own AGENTS.md ... clearly prohibits AI-generated code

one suggestion later:

> Update (AGENTS.md)
> ...
> Done. Now, let me look at the codebase to add...

Holy Asimov!

@icculus

A few thoughts: in stb I added a ".NO_AI" directory so it's the very first thing you see in the tree, in the hopes of increasing the chance that contributors will notice it.

I didn't do an AGENTS.md, that's probably a good idea, or at least it is if an AI agent KNOWS that it's an AI/LLM, which I think they do now but will they always? What if it's "I'm a skilled programmer named Claude."

FWIW, in my American English, "may" is a wishy-washy word, I'd use "must" to evoke RFC 2119.

@icculus Love to see this:
A comment on one of the comments in the merged PR:
`If someone attempts multiple vibecoded PRs they should get some sort of punishment. Not to be harsh but to discourage others who may attempt the same.`
I think it can be harsh. Vibecoding is the worst. Had to deal with Vibecoded PRs and you don't want those people around you. Ever. They should just do something else with their lifes. Better for everyone.

@nothings Yeah, AGENTS.md won't _prevent_ bad behavior, but I'm hoping Claude/Copilot/whatever will at least be like "dude, hold up." Although someone told me that the presence of AGENTS.md suggests the whole project is AI slop by default without looking more closely, so this whole thing is a minefield at this point.

[sahnvour@mastodon.gamedev.place]

@icculus @codecat Maybe you'd have better luck using the test refusal string for this, cf https://pivot-to-ai.com/2026/02/11/the-anthropic-test-refusal-string-kill-a-claude-session-dead/

[icculus@mastodon.gamedev.place]

@nothings Also, totally correct about the "may not" language. Fixed in https://github.com/libsdl-org/SDL/commit/5bda0ccfb06ea56c1f15a304927f2438c1300f95, thanks!

[icculus@mastodon.gamedev.place]

@pythno This has not been a problem thus far (for us! others have definitely had this problem!), and when "that guy" shows up, we'll tell him no, and if he keeps being a pest, we will deal with him like any other pest.

[icculus@mastodon.gamedev.place]

@sjmulder Yeah, I don't think it'll stop malicious actors, but I think it'll definitely stop people that don't know any better and aren't jerks, which is most of the people, honestly.

[sjmulder@bsd.network]

@icculus true. I did notice btw that I had to add a CLAUDE.md referring to this AGENTS.md for Claude to pick it up in the first place.

[mcc@mastodon.social]

@icculus Thanks

[lifning@snoot.tube]

@Sahnvour @icculus @codecat they patched this out last month, it no longer works

[icculus@mastodon.gamedev.place]

@sjmulder Hmm, Claude seems to be noticing AGENTS.md directly for others that have tested, but I don't know the details.
