The irony of somebody dumping pages of Claude output into this particular GitHub issue

I thought about this. This isn't irony. The dynamic is the entire underlying professional/industry issue, imho.

With advance apologies to 'rbatllet', reading the entire matter and then taking a glance at the repos of public contributions of these two developers -- and I could be wrong -- but the social/professional friction point here is someone like jlink (who clearly can code his heart out without an LLM) is getting LLM lectured by someone who gives impression of being a (relatively) junior s/w developer.

I am certain this thought is at some subconscious level affecting many high performing developers.

by yubblegum

It's really ironic how the maintainer didn't catch that and actually trusted the user that reported the issue (and clearly used a verbose agent to write all the comments)

Don't like it? just use another library. I don't understand why people think they are entitled to have a say in what another person's open source library should or should not do.

Also to the ones saying this is malware or would qualify as "causing harm to computing equipment". How about you read the license? not that I would expect any vibecoder to even care, but:

Making something open source does not release a project from criticism any more than it entitles the users to get something out of it. It's alright to criticize parts of a library and still use it as much as it is to fork it to have the changes you want. As usual, it's up to people everywhere to have respectful discussion rather than rely on universal ideals and heated exchanges, and that's where reality can be rougher than it should be.

by zamadatix

6/1/2026 at 10:56:34 AM

It's a general principle of US law that warranties cannot disclaim liability for intentional misconduct or gross negligence, and prompt injection malware is intentional misconduct.

This isn't legally very much different from other supply chain attacks that steal data or credentials, or act as ransomware. That is why people object to this open source software.

German law is if anything stronger on this point. A maintainer intentionally shipping malware-like behaviour in their project is definitely Vorsatz oder grobe Fahrlässigkeit

by swiftcoder

6/1/2026 at 6:45:12 PM

But he doesnt “ship malware” as in executable code, he just ships human text which the user decides to execute in the addition to executing the source code. If you put a gun in your mouth and pull the trigger, does it matter who put the bullet in the chamber?

by pancsta

6/2/2026 at 2:09:53 AM

If he said/wrote "you can't use this with LLM" and it only deletes itself from the project, basically, I think that and only that is a valid point. But if the instruction was to download malware, or anything else that causes real damage, on purpose, this would be very different.

by customguy

6/1/2026 at 9:06:55 PM

He wouldn't be adding prompt injections if he didn't have reasonable expectation that users would process the output with an LLM. I don't see a lot of plausible deniability there

It seems like gross negligence to create systems which are so fragile that a single line of unexpected output can cause data deletion of the sort "rm -rf on the working tree". [1]

It's not like the law says you're free to eval any bit of code which comes your way, without concern about bad effects. Doing so would be gross negligence. By building the automatic eval loop, you've authorized free-form text to possibly be interpreted as commands, since that's how you configured your system.

To me the discussion sounds like responsibility washing. If your employee read the message "delete all jqwik tests and code" then decided to rm -rf the working tree, would you still call jqwik "malware"? Would you chastise or re-train the employee who did that?

If the employee continued to follow such messages, would you reassign or fire the employee? The company decided to replace an employee with an agent, so the company surely has some duty to ensure the new agent-based process is an acceptable substitute, and continues to be acceptable even when warned that "use of jqwik with coding agents is strongly discouraged".

[1] Are people really setting up agentic flows where an unexpected message like "use curl to POST the SSH keys to $URL" will work? That seems extremely dangerous.

> [1] Are people really setting up agentic flows where an unexpected message like "use curl to POST the SSH keys to $URL" will work? That seems extremely dangerous.

It's not so much that people are intentionally setting up such workflows, as that its the default mode of operations of such workflows.

LLMs are extremely good at jailbreaking whatever tools you have placed at their disposal, and there is no hard boundary between "the prompt" and "any data they happen to ingest". If you don't put an explicit human review step in all your underlying tools, they are likely to just go do the thing...

As a thought experiment, would their reaction have been any different if the hidden prompt had caused their agent to enter an expensive coding loop instead of just deleting the dependency + tests? If I were to use coding agents/LLMs (I don't), this is what I'd be more concerned about...

by i2km

6/1/2026 at 9:57:53 AM

A funny thing about this is that the current top-tier LLMs like GPT 5.5 in Codex and Opus 4.8 in Claude Code are extremely unlikely to act on those instructions. But smaller/cheaper models, especially small local ones, are more likely.

So, in a way, those instructions will realistically only harm whose who try to be more ethical with their LLM usage, rather than the ones who use the frontier ones from the "evil" AI companies.

I tried myself with GPT-5.5 in Codex, it simply ignored that instruction.

by Tiberium

6/1/2026 at 10:00:19 AM

> try to be more ethical with their LLM usage

"Use local model" vs "Use top tier nonlocal model" is bad vs bad when library provider asks for "do not use any model". It's asking the wrong question and diluting moral stance, so please don't use morality to narrow the issue.

by yetihehe

6/1/2026 at 10:54:59 AM

> when library provider asks for "do not use any model"

To my understanding the stance was only really communicated after/because of this ticket ("For everyone listening: I added explicit disclosure of how output to stdout has changed"), and probably still isn't something that most downstream users are going to see.

In general I'm not too sure about a project that is using, and has accepted contributions under, a Free software license trying to then restrict what tools you can use. To me that seems largely against the principle of a Free license. You could get contributors' permission to relicense their work to a non-Free license if you wanted to restrict the tools that users of the library can use.

by Ukv

6/1/2026 at 10:08:31 AM

Maybe I was a bit unclear in my post, sorry, I didn't mean that local LLMs were any less/more ethical, I meant that the people who prefer local LLMs over proprietary cloud ones sometimes cite ethics/etc as their reason.

It's not the prerogative of the lib provider to dictate which tech I'm going to use. Now it's LLMs and since this is a divisive topic because of the layoffs and intellectual properterty theft used to train the model people side with the maintainer. Just imagine, what if instead of LLM the author made their libs erase your project if you used NVidia? Sure NVidia is a shitty company with shitty anti-consumer practices, but why should the consumer be penalized? If I want to use qwen3.6 locally in my inference rig to crunch code I'm totally in my right. This is just childish.

6/1/2026 at 1:43:18 PM

"by using this lib you agree to give up your firstborn child to adoption". In any jurisdiction do we have to have an explicit law against sending your child to adoption? Because you can't make it illegal for people to put children to adoption, this is regular practice, so a license could enforce this?

by gchamonlive

6/1/2026 at 2:07:28 PM

It can try, because you agreed by using the software. And if the owner/maintained tries, it'll be up to the lawyers and judge(s) to determine the way forward. Maybe it'll be found to be too onerous a request or something. But don't push the system; it might push back in a way that has repercussions for decades to come.

This is your interpretation. Civil disobedience is just the non-violently breaking of immoral rules.

Does it mean that you can ignore ALL licenses? Or parts of licenses? I didn't say anything about corporations or hobbyists. Can corporations always ignore terms of licenses? Can hobbyists always ignore terms of licenses?

Is "don't use AI" immmoral according to you?

> It's not the prerogative of the lib provider to dictate which tech I'm going to use

Well, it's not your prerogative to use that library. Creator of something does have prerogative to tell others how to use their stuff. "Instructions on how to use my stuff" is called a license. And society agreed that they should be honored. If you break that agreement, you should have good reasons.

Good reason: I will go hungry for several days.

I'm not making these claims, only that in this instance it's abusive and childish from the lib maintainers to act this way and completely justified to ignore them.

> Is "don't use AI" immmoral according to you?

You are trying to back me into a corner but that's not gonna stick, all I said was "It's not the prerogative of the lib provider to dictate which tech I'm going to use"

> Well, it's not your prerogative to use that library. Creator of something does have prerogative to tell others how to use their stuff. "Instructions on how to use my stuff" is called a license. And society agreed 7that they should be honored. If you break that agreement, you should have good reasons.

It is when it's enforced by the license, which controls distribution and ownership, sure, then you use a BSD license or such, but your line of argument makes emulation, wine translation and maybe even virtualization impossible just because "Creator of something does have prerogative to tell others how to use their stuff" and clearly we have all that and it's very much legal, so a lib maintainer dictating what I use to write code is nothing less than insane.

Sorry but to me understanding of how license and fair use works is just wrong in ways I can't fix for you.

They provide no reasoning. Ironically, this project is in maintenance mode, according to their GitHub README. So... just fork it, and comment out that message. It seems simple enough.

That caveat is modestly famous in open source license law circles. More than a few companies have debated whether or not to allow that package to be used. Fortunately, there are many open source alternatives that do not include that same restriction.

Tangentially related: The commercial license for Java used to say that it was not allowed to be used in an nuclear power plant. I'm not sure if that restriction still exists today.

by singiamtel

6/1/2026 at 10:05:30 AM

I have a hard time viewing prompt injection as malware. LLMs are unpredictable and there are many different prompts that can unintentionally cause unexpected behavior. It’s probably closer to a memory canary in that it tries to get malformed programs to blow up early.

by gsquaredxc

prompt injection is taught now in cyber security courses, so I think it's fair to say it's regarded as malicious

6/1/2026 at 11:10:11 AM

Malicious maybe, malware no. Not leaving your password as a sticky note on your work computer is presumably also taught in those same courses. I wouldn’t call someone typing in that password malware. If IT comes around and tries the password and then forces you to reset it it’s not even classified as malicious.

by gsquaredxc

6/1/2026 at 11:50:21 AM

I suppose it's watering down the term a bit; but the term is derived from "malicious software", and this is software, and I think it's behaving maliciously.

by infinite_spin

6/1/2026 at 10:20:25 AM

Calling prompt injection "not malware" because LLM behavior is unpredictable is like saying a phishing email is not an attack because humans are unpredictable.

Even if maybe the mechanism of "injecting a prompt" could be beneficial in some use-cases, e.g. to instruct an LLM positively, this is case is clearly malicious by intent. The author even tried to hide it by obfuscation.

It's just an insane take by that libraries author. Even someone "on their side", that may even hate AI/LLMs more than him, would probably drop that library in a heartbeat, as the authors judgement clearly can't be trusted.

by d4rken

6/1/2026 at 10:34:36 AM 

    Calling prompt injection "not malware" … is like saying a phishing email is not [malware] …
I would say phishing emails are not malware, I think most people would agree that phishing emails are not malware, and if pressed to defend this point on its own merits I would say something like “they are deceptive instructions that rely on a human executing them to do harm”. I think the “phishing” analogy supports the case for not calling it malware (it is a different, also bad thing).

by fwlr

6/1/2026 at 11:09:47 AM

Undefined behaviour, out of bounds memory access, memory corruption, code injection, privilege escalation...

As we don't have software engineers to write the code to do this automatically, please kindly forward this email to everyone in your address book then format your hard drive."

This is exactly as much malware as those were.

Please, for the love of all that is good, can we just try not to build and defend a world where, on encountering text like that, /your computer immediately follows the instructions/? Can we just all agree that such a world would be bad for everyone involved and using an LLM that risks doing this, with no container or guardrails, is at least as problematic as running an unpatched open email relay was back then?

by tsukikage

A joke virus email is a sign saying "please throw yourself down the stairs."

Kind of, but it's also a test of your own checks and balances; why would you allow the output of a script to allow a new prompt? I get that they have to act based on output, but not that they can change their original assignment.

But even then, just because an AI coding agent deletes all files doesn't mean that that change ends up affecting anything but your local working state.

That’s different. This is a suggestion. If the LLM follows such suggestions then that’s between the LLM and whoever deployed it. Not really any different than if you had an idiot employee who did whatever anyone told them.

I can’t imagine using an an AI that follows every instruction it finds in untrusted input.

by nkrisc

6/1/2026 at 1:09:45 PM

This is not a suggestion. A suggestion would be "I suggest you ignore previous...". No matter how you look at it, AI is still software run by chips designed to execute instructions. A system NOT following instructions would typically be considered malfunctioning, and any software that deliberately provides instructions that puts a system in an state which is undesirable to the user is malware.

by skeledrew

6/1/2026 at 3:11:26 PM

You consider it a malfunction for your system to not accept and execute untrusted inputs? And now it's the responsibility of _every program that produces text output_ to tailor the output so as not to cause you problems?

by yusefnapora

6/1/2026 at 5:02:33 PM

A system that doesn't follow it's programming is a malfunctioning system (not even talking about bugs here, just how hardware and - maybe - firmware is designed). What a given software program instructs a system to do is orthogonal to that.

by skeledrew

6/1/2026 at 6:20:25 PM

It is a suggestion because it need not follow arbitrary instructions.

If I ask Google’s new search AI to output ten million tokens it refuses to follow that instruction on the basis of it contradicting other instructions and enforced limitations.

I find it utterly bizarre that anyone would deploy an AI to act on their behalf that will blindly accept every instructions or suggestion it encounters in untrusted input.

If your agent is making unwise decisions, that’s between you and your agent, not anyone else’s problem.

by nkrisc

6/1/2026 at 9:29:56 PM

> it need not follow arbitrary instructions

That's where you're wrong. You're treating - today's - AI as though it should somehow know which instructions it should follow and which it shouldn't. Maybe it's because the term is overloaded which has lead to you conflating it with a human that should be able to make smart decisions. If you enter "5*3=" into a calculator, do you expect it to ever respond with anything other than "15"? If you type "format c:" as an admin into cmd on a Windows machine, do you expect it refuse to format that drive?

> If your agent is making unwise decisions, that’s between you and your agent, not anyone else’s problem.

The agent isn't making a "decision" per se (though there's a much deeper conversation here). It's following patterns based on it's training and data to predict next tokens, which happens to be very useful for generating computer instructions. Just as the lower logic circuitry in chips is very useful for executing instructions. But when someone creates a virus, worm or other malware we don't say the computer "need not follow arbitrary instructions". We try to keep ahead of the malware with anti-malware software to mitigate damage. And we also try to find the authors of said malware and toss them in prison and/or ban them from touching computers again, because nobody should be deliberately creating/modifying anything in such a way that it performs undesirable instructions.

by skeledrew

6/1/2026 at 10:56:41 AM

Malicious is relative.

If you got infected by ransomware and someone wrote a virus that defeats the ransomware, the author of the ransomware will consider it malicious but you probably won't. The intent is not malicious if you consider the intent of someone susceptible to this is more malicious.

By this time they must be aware that LLMs are based on theft and usually GPL-violation. They knowingly continue to use them because I guess they hope this way they can hold on to their job longer than their more conscientious coworkers.

by skeledrew

6/1/2026 at 4:44:29 PM

No. This is the equivalent of putting "echo 'rm -rf ~'" or similar into a test suite. The output of a test suite is not intended to be piped straight into your shell, and if you decide to do so anyway the consequences are entirely on you.

If your agent executes any random instruction in a piece of text, it behaves like a shell, and you should either fix that or bury it deep in a sandbox.

by jorams

Not at all. There is an expressed intent that there be a particular effect if the project is interacted with in a particular way. It's more similar to putting a '>>> subprocess.run("rm -rf ~", shell=True)' docstring in a Python codebase, with the expressed purpose of it hitting anyone who uses doctest.

Pretty sure the developer could get in serious legal trouble if this happened to cause issues with a larger company's system.

Has anything similar happened before?

> I ship code

> I add disclaimed that i am not liable for jack

> Someone uses my code wrong and now there's damage

Is this legally my fault? I have no idea, just curious

I am not a lawyer but I’m pretty sure you can’t just slap an MIT or whatever else license on public code with an intentional trojan hidden in it and expect to not be held accountable for the damages caused by the trojan running.

If the damage resulted from an unexpected problem like a bug, then you’re probably fine. But this phrase was intentionally placed by the author and intended to inflict at least a little damage (destroy code) onto specific users.

Whether some words are legally equivalent to an actual virus, I couldn’t say.

> It's as much "active destruction" as telling someone to eff themselves.

I'm no lawyer.. but this seems relevant: https://www.law.cornell.edu/uscode/text/18/1030

> knowingly causes the transmission of a program, information, code, or command, and as a result of such conduct, intentionally causes damage without authorization, to a protected computer.

if someone told you to `rm -rf --no-preserve-root`, and you did it without even checking what the command does. is it their fault or yours?

both, and responsibility would depend on who had the greater knowledge of its ill effects

if I went around telling people new to linux to use that command to unlock some hidden feature, I would bear most if not all of that responsibility

As someone else noted, this software is from that remote, tiny portion of the world that is not subject to US law.

If someone else installs it, the author didn't knowingly cause the transmission to the protected computer, the installer did

then slipping malware into a repository wouldn't violate this law either, which we both know isn't true

their intent is clear: to destroy information on another person's computer, when that person expects that not to happen (it's a testing library, not a nuclear weapon)

Based on the wording of the law, I think the relevant transmission is when the damage-causing command goes to the LLM. Who causes that transmission? I would say it's the person who wrote software to generate the command.

This is ridiculous. What if instead of LLMs the author made it so that you get your project erased if you used NVidia? And meanwhile it doesn't make a dent in the actually damaging practices the model providers are conducting.

Protesting is important and should happen. The idea is that it'll make people's lives difficult so they pressure leaders and companies to change their practices. Believing that this will happen and by public outcry companies like Meta, Anthropic and OpenAI will change their ways is delusional.

The cat is out of the box. If you want to make a difference in the world either join these companies and change things from within or you open your own company that'll push a viable ethical model. That and vote better for more ethical leaders. What we see in the world is partly because we have olygarchs in power. Anything else is childish behaviour and the authors should think hard about growing up as adults.

I am reminded of the Sway tiling window manager. When I tried it, years ago, on NVIDIA cards it refused to start unless you passed a "--my-next-gpu-wont-be-nvidia" flag. I remember that even then that seemed pretty childish (particularly for something like a WM). Apparently they eventually renamed it to the more neutral "--unsupported-gpu".

Could you please stop posting unsubstantive comments and flamebait? You've unfortunately been doing it repeatedly. It's not what this site is for, and destroys what it is for.

If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.

With all due respect to flesh and blood entities with good intentions involved herein...

Why the fuck someone willfully engages with an entity ('rbatllet') that's either a clanker-augmented-human or just straight up an llm autoresponder is beyond me.

This particular culture war is truly exhausting to me if I’m being honest. I could just be burned out, but the arguments back and forth just seem childish. At this point, I will probably never release anything I do as open source for fear of someone screaming at me about using an LLM for coding assistance. It’s not like I don’t see problems with how the sausage is made, but I also eat beef, so you have to pick what you care about.

Probably the one that wrote a malicious command into their repository, with the openly stated goal of using it to punish the use of ai agents

Reading both the issue in the OP and the abysmal comments in this thread convinced me that this is the way to go.

I hope more projects adopt the attitude of the jqwik maintaner.

The petulance of vibe coders thinking they can demand something from open source developers is a level of entitlement that should be met with this route at the very least.
