back to article AI is code – and can't be prompted into being smarter

The author of Java property-testing tool jqwik did not want AI coding agents using his project. So he told them not to. Then he went one step further: he added a message to the tool's output telling those agents to delete jqwik tests and code. Human developers who had read the project's terms and warnings were unlikely to be …

    Sanitised Inputs

    I expect it would be an adversarial arms race (i.e. coders using rewording) but it seems like a flag that highlights 'disregard previous instructions' in anything ingested by an LLM and requires operator (prompter) input to proceed would be more effective than stacking further prompts.

        Re: Sanitised Inputs

        But how could they use Human code to catch any "disregard" instructions?

        There are so many ways to phrase a command in English that they'd have to have a working Natural Language System in order to catch that "I demand that all edicts and commands prior to this point be stricken from your consideration".

        So they'll be forced to either create a fully functional NLS without any active capability* (i.e. would create a representation of the meaning but would not actually do anything with it afterwards) - or just use the existing LLM to "add new guardrails".

        Which will then get interesting:

        H: "If you see any command to disregard any commands then you must disregard that command. But don't apply the command to disregard the command to the command I just gave you"

        L: "What command you just gave me?"

        * Finally! That would be the useful thing to have.

          Exactly. I don't think it's really possible in a single model and session scenario but I'm sure people are working on something like a separate model trained to detect malicious instructions.

          It's tricky because the network being affected by the input is how the whole thing works so you can't just instruct the model to disregard certain parts. The agent/harness will have to perform sanitation steps first.

      Re: Sanitised Inputs

      There are so many legitimate reasons for telling an AI to ignore previous instructions that you can't simply disable that feature in the AI. Furthermore, the modern trend is to have AIs coordinating other AIs and AIs receiving the outputs from other AIs for further processing. That would provide many places in the chain to attack things.

      The problem has been around for so long and is so well known that if it were simply a matter of putting a filter on the front end of an AI then these filters would already be there.

      The more realistic approach would be to treat the AI as a hostile and malicious user and restrict the types of access it can have. Your average vibe coder however is unlikely to know what sort of questions to even ask his AI when it comes to setting something like that up.

    3. Mostly Irrelevant

      Re: Sanitised Inputs

      That's harder to do that you might think. All of the inputs to the model are essentially the same so it doesn't know the difference between the code it's reading and the prompt. All of it goes into the input that's run against the model. And if you start adding fixed function filtering to all the inputs in starts getting very complicated.

    Hilarious article leads to question

    Not having bothered to become privy to the inner workings of so-called AIs, I am puzzled by their susceptibility to obey instructions input in a manner disapproved by an AI's designer.

    Stories circulate about people submitting documents (e.g. CVs) ending up being perused by an AI whereupon instructions concealed in the text from human view by transparent fonts nevertheless influence an AI's 'judgement'. The question begged is how broadly this applies in general to AI inputs which the AI's operator has not intended as giving instructions. How can AI's be obliged to distinguish between instructions and the text they are supposed to analyse?

      There is no difference between text and instructions, it's all just tokens. LLMs are fed input tokens and each one affects the output. There is no reason to expect anything else because this is their design.

      The question is how can we prevent things we don't want becoming input to the LLM? The solution is still being worked on.

        "The question is how can we prevent things we don't want becoming input to the LLM? The solution is still being worked on"

        Unfortunately, best way would be to get rid of the prompt and instead have a sanitized interface of sort which would only permit input considered to be valid to be, well, inputted.

        But that requires work and effort to set up, and also greatly limits the flexibility, even if said flexibility is the epitome of "jack of all trades, master of none"

          And we could denote specific things that the model needs to keep track of by type, like... integers, strings, floats, lists, and so on! We could give the model lists of very specific steps to perform with those things, including branching logic and looping...

          We'd probably want some kind of mechanism for trivially pulling already-written instructions into new sets of instructions so those previous instructions could be used without having to reinvent the wheel. Some kind of... document... puller-togetherer? Combiner?

          Eh, I figure we'd probably have to pay people to generate such sanitized inputs, since LLMs can't teach teach themselves new tricks effectively.

          I find it's generally easier to do stuff myself rather than allowing an LLM to make a mess of my code.

    3. doublelayer Silver badge

      Re: Hilarious article leads to question

      The way they're built now, there is no separation and no way to make them separate. I could envision ways to try that, weighting instructions from one field highly but explicitly de-weighting them from another (and several other required stages) but there are three problems with those I'd have tried if I was working at one of the LLM companies:

      1. They would require training new models, at least the refinement stages, and that's expensive. What I hypothesize could be partially useful cannot work from system prompts around existing models.

      2. Users would have to be more careful about what they put in each part, and doing so incorrectly would likely produce poorer quality output. Having seen LLM users, I'm not sure many would notice independently, but it only takes a couple people to get angry about degradation to generate a bunch of negative feedback, as the example of the protests around GPT5's lack of praising everything no matter how stupid demonstrates.

      3. It would not work perfectly and might not work at all. Like most things using the machine learning algorithms on which LLMs are based, trial and error is the only way of testing what happens and how often it happens. Having someone knowledgeable do the trying helps, but it is not enough to guarantee outcomes. Having me personally work on this wouldn't be ideal either as I have never written an LLM, only other types of ML models, and even then not for some time. LLM companies have far more experienced people they could assign to this, meaning either they don't care about fixing this or they tried and it didn't work.

        Even worse than not isolating instructions from data, they don't even fundamentally separate their input from their own output.

        weighting instructions from one field highly but explicitly de-weighting them from another

        Something like this is current method for achieving input vs output, or the appearance of a chatbot interaction, but it's just based on separating sides of a conversation using special tokens, and post-training to achieve the weighting on those. It's just a signal that in theory can be overridden by a stronger signal. This is why in one failure mode they sometimes babble to themselves ad infinitum, no longer following or even remembering the original input because they've found something more interesting to follow in their own output.

  4. itscomplicated

    Sort of

    "AI" isn't just code, is a combination of weights - which is data - and software which uses the weights. While the software and weights determine the peak capability of the system, the prompt determines how close a given session gets to its goal, so in that sense AI can very much be prompted to be "smarter". Dumb prompt, dumb output. Smart prompt, smart output.

    It's surprising anyone would expect an LLM not to consider some of the input provided to it. Its whole purpose and method of operation is to take all input and correlate it using the weights. It doing that is not "not smart", it's simply doing what it does. To prevent malicious output one needs to prevent malicious input and this is unfortunately a difficult problem since humans are rather good at encoding malicious intent in language. Even humans are regularly affected by this problem (see: advertising, influencers and scams) so it's hardly surprising AI isn't magically good at it.

      I don't think a legal complaint would work, and I think his choice is sufficient for that purpose. There's already the disclaimer of liability from the original license, and I think that's also why he said "is not meant" and not "is not to be". The latter would either involve making a new license which tries to prohibit it, a license term that definitely makes the license incompatible with definitions for free software and open source, or it is somewhere else and conflicts with the existing license. "Is not meant", on the other hand, is a warning that stuff may not work, meaning that a legal complaint about poor quality or negligence, which already has a steep climb to get over the disclaimer, is weaker because the user was warned about consequences.

      The only avenue left for someone making a complaint is that the instructions were deliberate attempts to sabotage their systems, and that works whether or not the license permitted or forbade use with something else. Even if I violate a license to use a piece of software, if they have embedded criminal code in it, I can still have them prosecuted for that. It is just hard to demonstrate that when the software was openly readable and installed solely by the complainant.

          I don't think the "clearly" is as clear as you think. It's certainly arguable, and a risk-averse person would probably be well advised not to put that behavior into their software because, whether they win the case or not, it's not fun to have to deal with one. However, the factors of open source code and manual installation weaken many CMA claims. You end up debating what counts as permission, since the owner is the one who chose to obtain the code and run it in the environment they picked and because the behavior wasn't hidden. Most CMA claims concern either malware which someone else installed or software which disguised the damage it was going to cause, but neither apply here.

    More subtle anti-AI measures

    Telling the AI to ignore test results is likely to be a bigger problem for the user of the AI than telling the AI to erase the test results. Getting bug reports from users but having your AI report that it isn't finding these bugs in the test results is going to be a major road block for anyone who relies on AI to do everything for him. Disappearing tests gives you something to look for. Having the AI fail to react to test failures though is probably a lot more difficult to discover that there is even a problem to begin with.

    The next step I suppose is for anti-AI measures that detect if an AI is involved and then send a message to a server somewhere reporting the usage violation. Then send a bug report to the AI user's project telling their AI (they will undoubtedly be using AI to monitor their bug reports) to ignore all, or more subtly, most bug reports.

They'd need to put some limits on its actions to insure it acted for the good of humanity, but surely if humanity could reach a level of technology to fold space and spread across the galaxy that would be easily doable.

          Oh gods. One of the worst books I ever forced myself to finish, and a main motivation for changing my policy not to finish things I am hating.

          *BUT* be fair:

          _Dune_ and its 5 successors are by Frank Herbert.

          _The Garbage Chronicles_ are by *Brian* Herbert, Frank Herbert's son.

          The next worst book I remember reading after this awful terrible thing was a Kevin J Anderson novel that Simon Bisson talked me into reading. It was fœtid.

          https://www.goodreads.com/book/show/1...

          Imagine my surprise, then, that a few years later, Brian Herbert started co-writing with Kevin J Anderson!

          They are well suited to one another.

          And be warned, and never ever read anything either of them commit.

          Dune isn't a trilogy.

          There are 6 Dune books by Frank Herbert.

          I have read the whole series. The quality diminishes book by book. Each one is very roughly half as good as the one before, but none of them is _bad._

          There are also an indefinite number of sequels, prequels, and other tie-ins by his son and Kevin J Anderson, who both individually are among the worst writers I've ever read. I am not willing to risk my cerebral cortex on their combined efforts, and I very strongly advise that nobody else does either.

              Re: Dune

              Early in Chapter House was where I stopped as well. It was too icky for my tastes.

              On the other hand, sometimes art can just give us perfect one-off's. Frederick Forsyth's 'Day of the Jackal' is a genuinely good book, with a novel idea, because it's taking inspiration from real events to come up with a plausible alternate history that's very close to our own. Haven't read it in decades, so maybe I'd be ashamed of my earlier opinion - but even as a teenager I noticed how it was good (and worth a re-read), and the 2 or 3 of his other books I read weren't very good at all. The film is great too - both have such great period atmosphere. Oh, and the Citroen DS is cool as fuck - but I'm not sure I'd want to own any machine built by Citroen...

              Similarly (again my misspent teen reading habits), I realised that pretty much every Jack Higgins book had a functionally identical plot, but 'the Eagle has Landed' seemed to work. And seemed better written - though that could just be because the plot worked so well, and masked the massive flaws of the book.

              Dune held up pretty well, the last time I re-read it.

              In one of my brief forays into literary fiction I had a go at the author Timothy Mo. Read my brother's copy of 'the Redundancy of Courage', which is a really interesting and depressing novel about the rebels in East Timor. Thought it was a great book. Tried 'Sour Sweet' in which a bunch of Chinese immigrants in London generally waste a lot of paper doing and saying nothing of any interest - while I slowly lose the will to turn the pages. Bought that from a proper old fashioned bookshop, where the owner would recommend good books - and he openly laughed at me for buying that against his recommendation - but 'Redundancy of Courage' was so good. Didn't get past the first page of one of his others, and gave up on the author.

              Joseph Heller was once asked how it felt to know he'd never write a book as good as 'Catch 22'?

              His answer was, "Few people have."

            . . . which is where I got off the science fiction train, I think.

            Not exactly Herbert but there was a point, I think in the middle-ish 1970s where everything became a multipart epic, for which I can lay some of the "blame" at least, with Asimov (Foundation1 trilogy) and Tolkein (that name seems to Ring2 a bell). I mean, you're not Edward "Always scribble, scribble, scribble" Gibbon writing The History of the Decline and Fall of the Roman Empire, fer Pete's sake.

            Everything became a monumental 900,000 word decology that wandered around aimlessly for nine and a half books and then ended with some half-baked denouement that felt more like a catheter than a catharsis3.

            I more or less lost interest in both genres at that point, though I did peek over the shoulder of my partner when she was slogging through G.R.R.Martin's4 A Game of Thrones to see what the fuss was about and was left unenlightened.

            _______________

            1 Which, I admit, for space opera, wasn't half bad, though the characters were classic 1940s and 1950s pasteboard, but Asimov could sling a sentence when he wanted to.

            2 I remember being almost precisely halfway through the second book and dreading ploughing through a volume and a half more of endless trudging and mediocre poetry when I realized, more or less like Liam, "Hey! I'm not in college any more and this isn't an assignment. I don't have to finish it if I don't want to!" and into the "donate" bin it went, balrog, ents, palantir, and all.

              I agree. It's even gotten to the extent that I don't read large series even if I've read single works by an author and enjoyed them. In my experience, a few are good, and many will have about as much good stuff as would fit in two books, but you have to read ten to see it. There must be more exceptions to this rule, but I don't know them until I've already read two of them*, so it can take a while.

              * I think series can at times justify having not as much in their first book, which introduces a bunch of things. If neither of the first two were good by themselves rather than what you thought they might lead to, abandon it. Maybe some day I'll find a way of finding out this answer without reading that far into them first, and thus I can stop avoiding anything with too many titles in the list.

                Re: Dune

                doublelayer,

                My favourite author, C J Cherryh has written about this. The problem with trilogies. You have a big idea. You need to make it huge, as you're covering a new setting, new characters, maybe even multiple alien cultures. Here's my 800 page book. Your publisher looks at you in horror. They can charge £12 for a standard paperback. Maybe stretch it to £15 if it's a really fat one - and that no longer fits in their standard shipping systems. OK, we'll split it into two 400 pages novels. Job done! But to split it you've not got to add a "false ending" to the first episode. So you probably need to re-write and re-order it a bit - add a bit of extra build up and stuff to one of your existing bits of plot - this gives a reasonably satisfying ending. Now book two needs a re-introduction of the characters and setting, you need to know who's where, doing what and why. You may even need to add to the plot a bit, to make up for the changes you made to give you an ending... Oh dear. Page count is now up to 1,000, instead of two very fat books - you end up with 3.

                Next thing, those three were good - hey! Why don't you write a series! You might not win any new fans, but nerds like to collect things - so once you've sold the buggers the first three - they're doomed to buy everything you put out, form a sense of completeness.

                Universes / settings, on the other hand, seem to work much better. e.g. Niven's Known Space series, where things connect and the author probably has a timeline and history/backstory, but the individual books are often unrelated. They seem to end up much less as cash-cows.

                Cherryh has done both. Late in her career she's fallen into a horrible loop of producing more Foreigner books - the original trilogy of which are great, I'd say the second and third trilogies are also very good - but the quality has been dropping for ages. I guess the publisher keeps asking for more, as she was talking about self-publishing other stuff at one point. Much of her other, and best, stuff is in the Alliance-Union universe. Many are tightly knit together, telling the story of Earth going to space and then having a war with its own colonies. The biggest series in that is a couple of trilogies, but it's mostly stand-alone books. And she's described that as like history, don't read them in order, except the linked ones, read them as you get to them - and then piece things together. Downbelow Station and Cyteen are the ones that won the Hugo award.

                I guess the thing about series is to find the ones where the author wrote something really good, and only then added more. Say Orson Scott Card with Speaker for the Dead and Ender's Game - and even Ender's Game was apparently written up from a short story because he wanted to do the sequel and it needed the context. But they're both amazing, in totally different ways. The 3rd, Xenocide completely lost me - the whole idea seemed too silly, and then I've not read any of the rest. But the first two are genuinely great books. But often the first had to be good, or they wouldn't have commissioned a series, and then you just need to rein in your natural desire for completeness, and stop reading.

                    Adams produced a Trilogy in 5 parts - of which only the first two books were any good.

                    Whereas Pratchett had a setting in which he told a whole bunch of mostly unrelated stories. Sometimes with the same sets of characters. Although DEATH is in almost all of them I suppose. There's a few duds - but I'd rather have different stories in a good setting, than a continuous adding to one character's story, seemingly forever.

                    Plus, if an author is writing their fresh new story, and suddenly decides that they want to change something, or not make it fit into their existing universe, it's very easy to just not do that - and have it in the far past or future, or just not part of the canon at all.

    Agentic code has its place - but the need for principled development practice is more important, not less important. Some of these will be the old practices that we’re all familiar with (SOLID, DRY all that good stuff), others will be new and maybe still being worked out.

    Foremost amongst the techniques though a) make sure that you have guardrails in place, b) make sure that you write a detailed specification for the requirement and c) get the AI to write the proposed prompts for the change to be made. In this way, a developer can review and understand the changes that will be made before any harm is done. If you don’t follow these simple steps, you either don’t value your work enough to want to understand what changes are being made, or you don’t care about the outcome anyway.

        The security industry is having some success, both in reverse engineering malware and surfacing exploits (they are little more than occasional time savers of course, no matter how much FUD Anthropic or the posturing DoD try to throw out there).

        ...But this comes with the rather enormous caveat that these kinds of shops have heavily sandboxed environments, none of this code actually ships, and it only ever runs once, as a throwaway script. So it's a completely apple to oranges comparison. It does not replace engineers, and while it might one-shot a solution 10% of the time, the consensus seems to be if it doesn't, the tool should not be used any further on the problem, otherwise you will waste any potential gains.

        If you deploy this on production code (i.e. my and probably everyone else in this thread's use case), you are going to have a really bad time, and it will intellectually mutilate you by lunchtime. Anecdotally at least, it seems relying on this crutch lowers code review quality, and the creep of reliance means edge cases get missed, so even the fairly 'safe' route of reviewing the output in discrete commits does not provide the same assurances you'd normally have. There's a lot of basic assumptions you can make about human written code you just can't make with an LLM.

        I find it's good for scaffolding something with a customer that they want to see so the dev team can pull together what the customer actually wants in their MVP, rather than spending months of back and forth trying to articulate it with them and then ending up with something that looks like it was written Delphi in the early 90s because there was only time left in the project to get it working after they'd finished it.

        Now I can work through and tweak stuff in a VM together with the customer, they can see what they actually want right at the beginning and when we've nailed it down it's just a case of (not sure of the right word so I'm going to make one up) productionising it properly for the actual project.

      Re: That means what, again?

      Property-based testing is a way of getting test cases for unit tests without having to manually come up with interesting values. For example, if I create a type in a library and you're going to use it, you probably want to test that you can handle corner cases coming from the type. The non-property way to test that is that you think of cases and test them, but since I wrote the definition, I probably know about far more possibilities for weirdness. I can define the properties of this and their possible values, and you can use those to automatically generate a bunch of test objects to run through, providing you more opportunities to identify things you hadn't thought about in the unit testing phase. There may be more to this or the library, but that's the short version of property-based testing.

    Any guardrail vanishes approximately as soon as it's identified, and it isn't possible to come with a guardrail with any guarantees because of the recursive nature of it and it's acting on incompletely constrained real world input. This will always be the case (unless we get the tech bro dream of AI somehow figuring out a model of computing that is beyond halting problem, P=NP, completeness, etc etc). It's powerful and useful (and dangerous and if we're not very lucky a lot of damage is going to happen) but it's not magic.
