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

@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.

@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!

@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.

[seanmiddleditch@hachyderm.io]

@icculus @nothings I've seen a few other projects put something like an AGENTS_NOT_PERMITTED.md file with a link to the policy next to the regular agents file, so it's at least more obvious at a glance why the agents file is there.

No, the tools don't actually recognize that file in anyway. It's just a signal for humans to reduce knee jerk reactions to the agents file presence without having read it.

@icculus Really glad to see this!

@icculus Hell yeah SDL

@icculus Thank you!
