Codex has always been better at following agents.md and prompts more, but I would say in the last 3 months both Claude Code got worse (freestyling like we see here) and Codex got EVEN more strict.
80% of the time I ask Claude Code a question, it kinda assumes I am asking because I disagree with something it said, then acts on a supposition. I've resorted to append things like "THIS IS JUST A QUESTION. DO NOT EDIT CODE. DO NOT RUN COMMANDS". Which is ridiculous.
Codex, on the other hand, will follow something I said pages and pages ago, and because it has a much larger context window (at least with the setup I have here at work), it's just better at following orders.
With this project I am doing, because I want to be more strict (it's a new programming language), Codex has been the perfect tool. I am mostly using Claude Code when I don't care so much about the end result, or it's a very, very small or very, very new project.
>I've resorted to append things like "THIS IS JUST A QUESTION. DO NOT EDIT CODE. DO NOT RUN COMMANDS". Which is ridiculous.
Funny to read that, because for me it's not even new behavior. I have developed a tendency to add something like "(genuinely asking, do not take as a criticism)".
I'm from a more confrontational culture, so I just assumed this was just corporate American tone framing criticism softly, and me compensating for it.
Same here. I quickly learned that if you merely ask questions about it's understanding or plans, it starts looking for alternatives because my questioning is interpreted as rejection or criticism, rather than just taking the question at face value. So I often (not always) have to caveat questions like that too. It's really been like that since before Claude Code or Codex even rolled around.
It's just strange because that's a very human behavior and although this learns from humans, it isn't, so it would be nice if it just acted more robotic in this sense.
Yeah, numerous times I've replied to a comment online, to add supporting context, and it's been interpreted as a retort. So now I prefix them with 'Yeah, '.
Splitting tasks like researching, coding and reviewing across multiple LLMs and/or sessions, can reduce or eliminate these issues while giving you more control over your context windows. This also provides the side benefit of a ‘second opinion’ and a more general perspective on a given topic.
You're absolutely right! No, really: I've never had this problem of unprompted changes when I'm just asking, but I always (I think even in real-life conversations with real people) start with feedback: "Works great. What happens if..."
I think people having different styles of prompting LLMs leads to different model preferences. It's like you can work better with some colleagues while with others it does not really "click".
Oh funny enough, I often add stuff like "genuinely asking, do not take as a criticism" when talking with humans so I do it naturally with LLMs.
People often use questions as an indirect form of telling someone to do something or criticizing something.
I definitely had people misunderstand questions for me trying to attack them.
There is a lot of times when people do expect the LLM to interpret their question as an command to do something. And they would get quite angry if the LLM just answered the question.
Not that I wouldn't prefer if LLMs took things more literal but these models are trained for the average neurotypical user so that quirk makes perfect sense to me.
Personally defined <dtf> as 'don't touch files' in the general claude.md, with the explanation that when this is present in the query, it means to not edit anything, just answer questions.
Worked pretty well up until now, when I include <dtf> in the query, the model never ran around modifying things.
I've been using chat and copilot for many months but finally gave claude code a go, and I've been interested how it does seem to have a bit more of an attitude to it. Like copilot is just endlessly patient for every little nitpick and whim you have, but I feel like Claude is constantly like "okay I'm committing and pushing now.... oh, oh wait, you're blocking me. What is it you want this time bro?"
I found that helpful for a question but the btw query seemed to go to a subagent that couldn't interrupt or direct the main one. So it really was just for informational questions, not "hey what if we did x instead of y?"
Yesterday it was showing a hint in the corner to use "/btw" but when I first tried it I got this same error. About ten minutes later (?) I noticed it was still showing the same hint in the corner, so I tried it again and it worked. Seemed to be treated as a one-off question which doesn't alter the course of whatever it was already working on.
It's not really the same use case. It's a smaller model, it doesn't have tools, it can't investigate, etc. The only thing it can do is answer questions about whatever is in the current context.
Then it will try to update plan. Sometimes I have a plan that I'm ready to approve, but get an idea "what if we use/do this instead if that" and all I want is a quick answer with or within additional exploring. What I don't want is to adjust plan I already like based of a thing I say that may not pan out.
Charitable reading. Culture; tone; throughout history these have been medium and message of the art of interpersonal negotiation in all its forms (not that many).
A machine that requires them in order to to work better, is not an imaginary para-person that you now get to boss around; the "anthropic" here is "as in the fallacy".
It's simply a machine that is teaching certain linguistic patterns to you. As part of an institution that imposes them. It does that, emphatically, not because the concepts implied by these linguistic patterns make sense. Not because they are particularly good for you, either.
I do not, however, see like a state. The code's purpose is to be the most correct representation of a given abstract matter as accessible to individual human minds - and like GP pointed out, these workflows make that stage matter less, or not at all. All engineers now get to be sales engineers, too! Primarily! Because it's more important! And the most powerful cognitive toolkit! (Well, after that other one, the one for suppressing others' cognition.)
Fitting: most software these days is either an ad or a storefront.
>80% of the time I ask Claude Code a question, it kinda assumes I am asking because I disagree with something it said, then acts on a supposition.
Humans do this too. Increasingly so over the past ~1y. Funny...
Some always did though. Matter of fact, I strongly suspect that the pre-existing pervasiveness of such patterns of communication and behavior in the human environment, is the decisive factor in how - mutely, after a point imperceptibly, yet persistently - it would be my lot in life to be fearing for my life throughout my childhood and the better part of the formative years which followed. (Some AI engineers are setting up their future progeny for similar ordeals at this very moment.)
I've always considered it significant how back then, the only thing which convincingly demonstrated to me that rationality, logic, conversations even existed, was a beat up old DOS PC left over from some past generation's modernization efforts - a young person's first link to the stream of human culture which produced said artifact. (There's that retrocomputing nostalgia kick for ya - heard somewhere that the future AGI will like being told of the times before it existed.)
But now I'm half a career into all this goddamned nonsense. And I'm seeing smart people celebrating the civilization-scale achievement of... teaching the computers how to pull ape shit! And also seeing a lot of ostensibly very serious people, who we are all very much looking up to, seem to be liking the industry better that way! And most everyone else is just standing by listless - because if there's a lot of money riding on it then it must be a Good Thing, right? - we should tell ourselves that and not meddle.
All of which, of course, does not disturb, wrong, or radicalize me in the slightest.
First time I used Claude I asked it to look at the current repo and just tell me where the database connection string was defined. It added 100 lines of code.
I asked it to undo that and it deleted 1000 lines and 2 files
Would `git reset --hard` have worked to in your case? I guess you want to have each babystep in a git commit, in the end you could do a `git rebase -i` if needed.
Whatever settup I have in the office doesn't allow git without me approving the command. Or anything else - I often have to approve a grep because is redirects some output to /dev/null which is a write operation.
One annoying thing about that flow is that when you change the world outside the model it breaks its assumptions and it loses its way faster (in my experience).
I feel like people are sleeping on Cursor, no idea why more devs don't talk about it. It has a great "Ask" mode, the debugging mode has recently gotten more powerful, and it's plan mode has started to look more like Claude Code's plans, when I test them head to head.
Cursor implemented something a while back where it started acting like how ChatGPT does when it's in its auto mode.
Essentially, choosing when it was going to use what model/reasoning effort on its own regardless of my preferences. Basically moved to dumber models while writing code in between things, producing some really bad results for me.
Anecdotal, but the reason I will never talk about Cursor is because I will never use it again. I have barred the use of Cursor at my company, It just does some random stuff at times, which is more egregious than I see from Codex or Claude.
ps. I know many other people who feel the same way about Cursor and other who love it. I'm just speaking for myself, though.
ps2. I hope they've fixed this behavior, but they lost my trust. And they're likely never winning it back.
You just described their “auto” behavior, which I’m guessing uses grok.
Using it with specific models is great, though you can tell that Anthropic is subsidizing Claude Code as you watch your API costs more directly. Some day the subsidy will end. Enjoy it now!
And cursor debugging is 10x better, oh my god.
I have switched to 70% Claude Code, 10% Copilot code reviews (non anthropic model), and 20% Cursor and switch the models a bit (sometimes have them compete — get four to implement the same thing at the same time, then review their choices, maybe choose one, or just get a better idea of what to ask for and try again).
You wouldn't do that for everything. I'd reserve it for work with higher uncertainty, where you're not sure which path is best. Different model families can make very different choices.
In the coworking I am in people are hitting limits on 60$ plan all the time. They are thinking about which models to use to be efficient, context to include etc…
I’m on claude code $100 plan and never worry about any of that stuff and I think I am using it much more than they use cursor.
Tell them to use the Composer 1.5 model. It's really good, better than Sonnet, and has much higher usage limits. I use it for almost all of my daily work, don't have to worry about hitting the limit of my 60$ plan, and only occasionally switch to Opus 4.6 for planning a particularly complex task.
Cursor tends to bounce out of plan mode automatically and just start making changes (while still actually in plan mode). I also have to constantly remind it “YOU ARE IN PLAN MODE, do not write a plan yet, do not edit code”. It tends to write a full-on plan with one initial prompt instead of my preferred method of hashing out a full plan, details, etc… It definitely takes some heavy corralling and manual guardrails but I’ve had some success with it. Just keep very tight reins on your branches and be prepared to blow them away and start over on each one.
I've had some luck taming prompt introspection by spawning a critic agent that looks at the plan produced by the first agent and vetos it if the plan doesn't match the user's intentions. LLMs are much better at identifying rule violations in a bit of external text than regulating their own output. Same reason why they generate unnecessary comments no matter how many times you tell them not to.
I've also found it to be better to ask the LLM to come up with several ideas and then spawn additional agents to evaluate each approach individually.
I think the general problem is that context cuts both ways, and the LLM has no idea what is "important". It's easier to make sure your context doesn't contain pink elephants than it is to tell it to forget about the pink elephants.
> what "red/green" means: the red phase watches the tests fail, then the green phase confirms that they now pass.
> Every good model understands "red/green TDD" as a shorthand for the much longer "use test driven development, write the tests first, confirm that the tests fail before you implement the change that gets them to pass".
You can just say spawn an agent as the sibling says. I didn't find that reliable enough, so I have a slightly more complicated setup. First agent has no permissions except spawning agents and reading from a single directory. It spawns the planner to generate the plan, then either feeds it to the critic and either spawns executors or re-runs the planner with critic feedback. The planner can read and write. The critic agent can only read the input and outputs accept/reject with reason.
This is still sometimes flaky because of the infrastructure around it and ideally you'd replace the first agent with real code, but it's an improvement despite the cost.
Codex, on the other hand, will follow something I said pages and pages ago, and because it has a much larger context window (at least with the setup I have here at work), it's just better at following orders.
This is important, but as a warning. At least in theory your agent will follow everything that it has in context, but LLMs rely on 'context compacting' when things get close to the limit. This means an LLM can and will drop your explicit instructions not to do things, and then happily do them because they're not in the context any more. You need to repeat important instructions.
This is mostly dependent on the agent because the agent sets the system prompt. All coding agents include in the system prompt the instruction to write code, so the model will, unless you tell it not to. But to what extent they do this depends on that specific agent's system prompt, your initial prompt, the conversation context, agent files, etc.
If you were just chatting with the same model (not in an agent), it doesn't write code by default, because it's not in the system prompt.
There’s an extension to this problem which I haven’t got past. More generally I’d like the agent to stop and ask questions when it encounters ambiguity that it can’t reasonably resolve itself. If someone can get agents doing this well it’d be a massive improvement (and also solve the above).
Hm, with my "plan everything before writing code, plus review at the end" workflow, this hasn't been a problem. A few times when a reviewer has surfaced a concern, the agent asks me, but in 99% of cases, all ambiguity is resolved explicitly up front.
This. Just asking it to ask you questions before proceeding has saved me so much time from it making assumptions I don’t want. It’s the single most important part of almost all my prompts.
The solution for this might be to add a ME.md in addition to AGENT.md so that it can learn and write down our character, to know if a question is implicitly a command for example.
This is not Claude Code.
And my experience is the opposite. For me Codex is not working at all to the point that it's not better than asking the chat bot in the browser.
This is extra rough because Codex defaults to letting the model be MUCH more autonomous than Claude Code. The first time I tried it out, it ended up running a test suite without permission which wiped out some data I was using for local testing during development. I still haven't been able to find a straight answer on how to get Codex to prompt for everything like Claude Code does - asking Codex gets me answers that don't actually work.
Maybe I should give Codex a go, because sometimes I just want to ask a question (Claude) and not have it scan my entire working directory and chew up 55k tokens.
I find this thread surprising honestly. Claude Code is my daily driver and I consider myself a real power user. If you have your commands/agents/skills set up correctly you should never be running into these issues
> Codex, on the other hand, will follow something I said pages and pages ago, and because it has a much larger context window (at least with the setup I have here at work), it's just better at following orders.
Claude Code goes through some internal systems that other tools (Cline / Codex / and I think Cursor) do not. Also we have different models for each. I don't know in practice what happens, but I found that Codex compacts conversations way less often. It might as well be somehow less tokens are used/added, then raw context window size. Sorry if I implied we have more context than whatever others have :)
Codex does something sorta magical where it auto compacts, partially maybe, when it has the chance. I don’t know how it works, and there is little UI indication for it.
But that's one of the first things you fix in your CLAUDE.md:
- "Only do what is asked."
- "Understand when being asked for information versus being asked to execute a task."
How do you do that???? Say the words but in the form of a question? I feel like that will go a lot worse than just telling (but nicely). I have a daughter too so I am genuinely willing to try anything
What about adding something like, "When asked a question, just answer it without assuming any implied criticism or instructions. Questions are just questions." to claude.md?
For the last 12 months labs have been
1. check-pointing
2. train til model collapse
3. revert to the checkpoint from 3 months ago
4. People have gotten used to the shitty new model
Antropic said they "don't do any programming by hand" the last 2 years. Antropic's API has 2 nines
I'm back on Claude Code this month after a month on Codex and it's a serious downgrade.
Opus 4.6 is a jackass. It's got Dunning-Kruger and hallucinates all over the place. I had forgotten about the experience (as in the Gist above) of jamming on the escape key "no no no I never said to do that." But also I don't remember 4.5 being this bad.
But GPT 5.3 and 5.4 is a far more precise and diligent coding experience.
Its gotten so bad that Claude will pretend in 10 of 10 cases that task is done/on screenshot bug is fixed, it will even output screenshot in chat, and you can see the bug is not fixed pretty clear there.
I consulted Claude chat and it admitted this as a major problem with Claude these days, and suggested that I should ask what are the coordinates of UI controls are on screenshot thus forcing it to look. So I did that next time, and it just gave me invented coordinates of objects on screenshot.
I consult Claude chat again, how else can I enforce it to actually look at screenshot. It said delegate to another “qa” agent that will only do one thing - look at screenshot and give the verdict.
I do that, next time again job done but on screenshot it’s not. Turns out agent did all as instructed, spawned an agent and QA agent inspected screenshot. But instead of taking that agents conclusion coder agent gave its own verdict that it’s done.
It will do anything- if you don’t mention any possible situation, it will find a “technicality” , a loophole that allows to declare job done no matter what.
And on top of it, if you develop for native macOS, There’s no official tooling for visual verification. It’s like 95% of development is web and LLM providers care only about that.
> I consulted Claude chat and it admitted this as a major problem with Claude these days, and suggested that I should ask what are the coordinates of UI controls are on screenshot thus forcing it to look
If 3 years into LLMs even HNers still don't understand that the response they give to this kind of question is completely meaningless, the average person really doesn't stand a chance.
The whole “chat with an AI” paradigm is the culprit here. Priming people to think they are actually having a conversation with something that has a mind model.
It’s just a text generator that generates plausible text for this role play. But the chat paradigm is pretty useful in helping the human. It’s like chat is a natural I/O interface for us.
I disagree that it’s “just a text generator” but you are so right about how primed people are to think they’re talking to a person. One of my clients has gone all-in on openclaw: my god, the misunderstanding is profound. When I pointed out a particularly serious risk he’d opened up, he said, “it won’t do that, because I programmed it not to”. No, you tried to persuade it not to with a single instruction buried in a swamp of markdown files that the agent is itself changing!
I insist on the text generator nature of the thing. It’s just that we built harnesses to activate on certain sequences of text.
Think of it as three people in a room. One (the director), says: you, with the red shirt, you are now a plane copilot. You, with the blue shirt, you are now the captain. You are about to take off from New York to Honolulu. Action.
Red: Fuel checked, captain. Want me to start the engines?
Blue: yes please, let’s follow the procedure. Engines at 80%.
Red: I’m executing: raise the levers to 80%
Director: levers raised.
Red: I’m executing: read engine stats meters.
Director: Stats read engine ok, thrust ok, accelerating to V0.
Now pretend the director, when heard “I’m executing: raise the levers to 80%”, instead of roleplaying, she actually issue a command to raise the engine levers of a plane to 80%. When she hears “I’m executing: read engine stats”, she actually get data from the plane and provide to the actor.
See how text generation for a role play can actually be used to act on the world?
In this mind experiment, the human is the blue shirt, Opus 4-6 is the red and Claude code is the director.
For context I've been an AI skeptic and am trying as hard as I can to continue to be.
I honestly think we've moved the goalposts. I'm saying this because, for the longest time, I thought that the chasm that AI couldn't cross was generality. By which I mean that you'd train a system, and it would work in that specific setting, and then you'd tweak just about anything at all, and it would fall over. Basically no AI technique truly generalized for the longest time. The new LLM techniques fall over in their own particular ways too, but it's increasingly difficult for even skeptics like me to deny that they provide meaningful value at least some of the time. And largely that's because they generalize so much better than previous systems (though not perfectly).
I've been playing with various models, as well as watching other team members do so. And I've seen Claude identify data races that have sat in our code base for nearly a decade, given a combination of a stack trace, access to the code, and a handful of human-written paragraphs about what the code is doing overall.
This isn't just a matter of adding harnesses. The fields of program analysis and program synthesis are old as dirt, and probably thousands of CS PhD have cut their teeth of trying to solve them. All of those systems had harnesses but they weren't nearly as effective, as general, and as broad as what current frontier LLMs can do. And on top of it all we're driving LLMs with inherently fuzzy natural language, which by definition requires high generality to avoid falling over simply due to the stochastic nature of how humans write prompts.
Now, I agree vehemently with the superficial point that LLMs are "just" text generators. But I think it's also increasingly missing the point given the empirical capabilities that the models clearly have. The real lesson of LLMs is not that they're somehow not text generators, it's that we as a species have somehow encoded intelligence into human language. And along with the new training regimes we've only just discovered how to unlock that.
> I thought that the chasm that AI couldn't cross was generality. By which I mean that you'd train a system, and it would work in that specific setting, and then you'd tweak just about anything at all, and it would fall over. Basically no AI technique truly generalized for the longest time.
That is still true though, transformers didn't cross into generality, instead it let the problem you can train the AI on be bigger.
So, instead of making a general AI, you make an AI that has trained on basically everything. As long as you move far enough away from everything that is on the internet or are close enough to something its overtrained on like memes it fails spectacularly, but of course most things exists in some from on the internet so it can do quite a lot.
The difference between this and a general intelligence like humans is that humans are trained primarily in jungles and woodlands thousands of years ago, yet we still can navigate modern society with those genes using our general ability to adapt to and understand new systems. An AI trained on jungles and woodlands survival wouldn't generalize to modern society like the human model does.
And this makes LLM fundamentally different to how human intelligence works still.
Iteration is inherent to how computers work. There's nothing new or interesting about this.
The question is who prunes the space of possible answers. If the LLM spews things at you until it gets one right, then sure, you're in the scenario you outlined (and much less interesting). If it ultimately presents one option to the human, and that option is correct, then that's much more interesting. Even if the process is "monkeys on keyboards", does it matter?
There are plenty of optimization and verification algorithms that rely on "try things at random until you find one that works", but before modern LLMs no one accused these things of being monkeys on keyboards, despite it being literally what these things are.
Of course it doesn't matter indeed. What I was hinting at is if you forget all the times the LLM was wrong and just remember that one time it was right it makes it seem much more magical than it actually might be.
Also how were the data races significant if nobody noticed them for a decade ? Were you all just coming to work and being like "jeez I dont know why this keeps happening" until the LLM found them for you?
> No, you tried to persuade it not to with a single instruction
Even persuade is too strong a word. These things dont have the motivation needed to enable persuation being a thing. Whay your client did was put one data point in the context that it will use to generate the next tokens from. If that one data point doesnt shift the context enough to make it produce an output that corresponds to that daya point, then it wont. Thats it, no sentience involved
It doesn’t help that a frequent recommendation on HN whenever someone complains about Claude not following a prompt correctly is to “ask Claude itself how to rewrite a prompt to get the result you want”.
Which sure, can be helpful, but it’s kinda just a coincidence (plus some RLHF probably) that question happens to generate output text that can be used as a better prompt. There’s no actual introspection or awareness of its internal state or architecture beyond whatever high level summary Anthropic gives it in its “soul” document et al.
But given how often I’ve read that advice on here and Reddit, it’s not hard to imagine how someone could form an impression that Claude has some kind of visibility into its own thinking or precise engineering. Instead of just being as much of a black box to itself as it is to us.
It’s not meaningless. It’s a signal that the agent has run out of context to work on the problem which is not something it can resolve on its own. Decomposing problems and managing cognitive (or quasi cognitive in this case) burden is a programmer’s job regardless of the particular tools.
This is way too strong isn't it? If the user naively assumes Claude is introspecting and will surely be right, then yeah, they're making a mistake. But Claude could get this right, for the same reasons it gets lots of (non-introspective) things right.
It's not too strong. If it answered from its weights, it's pretty meaningless. If it did a web search and found reports of other people saying this, you'd want to know that this is how it answered - and then you'd probably just say that here on HN rather than appealing to claude as an authority on claude.
They also said it "admitted" this as a major problem, as if it has been compelled to tell an uncomfortable truth.
Maybe I'm just being too literal, but I don't know if you're really disagreeing with me. I was disputing "the response they give to this kind of question is completely meaningless". An answer from its weights is out of date, but only completely meaningless if this is a completely new issue with nothing relevant in the training data. And, as you say, the answer could be search-based and up to date.
GP here, this is indeed exactly whT I was getting at, thanks for wording it for me; you put it better than I would've.
In this specific case I'd go one step further and say that even if it did a web search, it's still almost certainly useless because of the low quality of the results and their outdatedness, two things LLMs are bad at discerning. From weights it doesn't know how quickly this kind of thing becomes outdated, and out of the box it doesn't know how to account for reliability.
> And on top of it, if you develop for native macOS, There’s no official tooling for visual verification. It’s like 95% of development is web and LLM providers care only about that.
Thinking out loud here, but you could make an application that's always running, always has screen sharing permissions, then exposes a lightweight HTTP endpoint on 127.0.0.1 that when read from, gives the latest frame to your agent as a PNG file.
Edit: Hmm, not sure that'd be sufficient, since you'd want to click-around as well.
Maybe a full-on macOS accessibility MCP server? Somebody should build that!
There is a tool called Tidewave that allows you to point and click at an issue and it will pass the DIV or ID or something to the LLM so it knows exactly what you are talking about. Works pretty well.
> And on top of it, if you develop for native macOS, There’s no official tooling for visual verification. It’s like 95% of development is web and LLM providers care only about that.
Oh, no, I had these grand plans to avoid this issue. I had been running into it happening with various low-effort lifts, but now I'm worried that it will stay a problem.
>>It’s like 95% of development is web and LLM providers care only about that.
I've been trying to use it for C++ development and it's maybe not completely useless, but it's like a junior who very confidently spouts C++ keywords in every conversation without knowing what they actually mean. I see that people build their entire companies around it, and it must be just web stuff, right? Claude just doesn't work for C++ development outside of most trivial stuff in my experience.
Models are also quite good at Go, Rust, and Python in my experience — also a lot of companies are using TypeScript for many non web related things now. Apparently they're also really good at C, according to the guy who wrote Redis anyway.
It's working reasonably well for me. But this is inside a well-established codebase with lots of tests and examples of how we structure code. I also haven't used it much for building brand new features yet, but for making changes to existing areas.
GPT models are generally much better at C++, although they sometimes tend to produce correct but overengineered code, and the operator has to keep an eye on that.
I mean, I don't use CC itself, just Claude through Copilot IDE plugin for 'reasons'...
At at least there it's more honest than GPT, although at work especially it loves to decide not to use the built in tools and instead YOLO on the terminal but doesn't realize it's in powershell not a true nix terminal, and when it gets that right there's a 50/50 shot it can actually read the output (i.e. spirals repeatedly trying to run and read the output).
I have had some success with prompting along the lines of 'document unfinished items in the plan' at least...
Codex via codex-cli used to be pretty about knowing whether it was in powershell. Think they might have changed the system prompt or something because it’s usually generating powershell on the first attempt.
Sometimes it tries to use shell stuff (especially for redirection), but that’s way less common rn.
Are you sure you're talking about Claude? Because it sounds like you're describing how a lot of people function. They can't seem to follow instructions either.
I guess that's what we get for trying to get LLM to behave human-like.
What if, stay with me here, AI is actually a communist plot to ensorcell corporations into believing they are accelerating value creation when really they are wasting billions more in unproductive chatting which will finally destroy the billionaire capital elite class and bring about the long-awaited workers’ paradise—delivered not by revolution in the streets, but by millions of chats asking an LLM to “implement it.” Wake up sheeple!
I think there is some behind the scenes prompting from claude code (or open code, whichever is being used here) for plan vs build mode, you can even see the agent reference that in its thought trace. Basically I think the system is saying "if in plan mode, continue planning and asking questions, when in build mode, start implementing the plan" and it looks to me(?) like the user switched from plan to build mode and then sent "no".
From our perspective it's very funny, from the agents perspective maybe it's confusing. To me this seems more like a harness problem than a model problem.
This is a perfect example of why I'm not in any rush to do things agentically. Double-checking LLM-generated code is fraught enough one step at a time, but it's usually close enough that it can be course-corrected with light supervision. That calculus changes entirely when the automated version of the supervision fails catastrophically a non-trivial percent of the time.
To an LLM, answering “no” and changing the mode of the chat window are discrete events that are not necessarily related.
Many coding agents interpret mode changes as expressions of intent; Cline, for example, does not even ask, the only approval workflow is changing from plan mode to execute mode.
So while this is definitely both humorous and annoying, and potentially hazardous based on your workflow, I don’t completely blame the agent because from its point of view, the user gave it mixed signals.
The point is that if the harness’ workflow gives contradictory and confusing instructions to the model, it’s a harness issue, not necessarily a model issue.
First it was a model issue, then it was a prompting issue, then it was a context issue, then it was an agent issue, now it's a harness issue. AI advocates keep accusing AI skeptics of moving goalposts. But it seems like every 3-6 months another goalpost is added.
Your comment doesn’t make as strong of a point as you think it does; it might make the opposite point.
Because, yes, first, it was a model issue, and then more advanced models started appearing and prompting them correctly became more important. Then models learned through RLHF to deal with vague prompting better, and context management became more important. Then models became better (though not great) at inherent context recollection and attention distribution, so now, you need to be careful what instructions a model receives and at what points because it’s literally better at following them. It’s not so much that the goalposts are being moved, it’s that they’re literally being, like, *cleared*.
This isn’t a tech that’s already fully explored and we just need to make it good now, it’s effectively an entirely new field of computing. When ChatGPT came out years ago no one would have DREAMT of an LLM ever autonomously using CLI tools to write entire projects worth of code off of a single text prompt. We’d only just figured out how to turn them into proper chatbots. The point is that we have no idea where the ceiling is right now, so demanding well-defined goalposts is like saying we need to have a full geological map of Mars before we can set foot on it, when part of the point of going to Mars is to find out about that.
As a side point, the agent is the harness; or, rather, an agent is a model called on a loop, and the harness is where that loop lives (and where it can be influenced/stopped). So what I can say about most - not all, but most, including you, seemingly - AI skeptics is that they tend to not actually be particularly up-to-date and/or engaged with how these systems actually work and how capable they actually are at this point. Which is not supposed to be a dig or shade, because I’m pretty sure we’ve never had any tech move this fast before. But the general public is so woefully underinformed about this. I’ve recently had someone tell me in awe about how ChatGPT was able to read their handwritten note and solve a few math equations.
But I think if you sit down and really consider the implications of it and what yes or not actually means in reality, or even a overabundance of caution causing extraneous information to confuse the issue enough that you don't realise that this sentence is completely irrelevant to the problem at hand and could be inserted by a third party, yet the AI is the only one to see it. I agree.
It's meant as a "yes"/"instead, do ..." question. When it presents you with the multiple choice UI at that point it should be the version where you either confirm (with/without auto edit, with/without context clear) or you give feedback on the plan. Just telling it no doesn't give the model anything actionable to do
If we’re in a shoot first and ask questions later kind of mood and we’re just mowing down zombies (the slow kind) and for whatever reason you point to one and ask if you should shoot it… and I say no… you don’t shoot it!
This is probably just OpenCode nonsense. After prompting in "plan mode", the models will frequently ask you if you want to implement that, then if you don't switch into "build mode", it will waste five minutes trying but failing to "build" with equally nonsense behavior.
Honestly OpenCode is such a disappointment. Like their bewildering choice to enable random formatters by default; you couldn't come up with a better plan to sabotage models and send them into "I need to figure out what my change is to commit" brainrot loops.
This. The models struggle with differentiating tool responses from user messages.
The trouble is these are language models with only a veneer of RL that gives them awareness of the user turn. They have very little pretraining on this idea of being in the head of a computer with different people and systems talking to you at once. —- there’s more that needs to go on than eliciting a pre-learned persona.
The whole idea of just sending "no" to an LLM without additional context is kind of silly. It's smart enough to know that if you just didn't want it to proceed, you would just not respond to it.
The fact that you responded to it tells it that it should do something, and so it looks for additional context (for the build mode change) to decide what to do.
I agree the idea of just sending "no" to an LLM without any task for it to do is silly. It doesn't need to know that I don't want it to implement it, it's not waiting for an answer.
It's not smart enough to know you would just not respond to it, not even close. It's been trained to do tasks in response to prompts, not to just be like "k, cool", which is probably the cause of this (egregious) error.
I didn't mean to imply that it was. But when you reply to it, if you just say "no" then it's aware that you could've just not responded, and that normally you would never respond to it unless you were asking for something more.
It just doesn't make any sense to respond no in this situation, and so it confuses the LLM and so it looks for more context.
No, it has knowledge of what it is and how it is used.
I'm guessing you and the other guy are taking issue with the words "aware of" when I'm just saying it has knowledge of these things. Awareness doesn't have to imply a continual conscious state.
In my case it's been a strong no. Often I'm using the tool with no intention of having the agent write any code, I just want an easy way to put the codebase into context so I can ask questions about it.
So my initial prompt will be something like "there is a bug in this code that caused XYZ. I am trying to form hypothesis about the root cause. Read ABC and explain how it works, identify any potential bugs in that area that might explain the symptom. DO NOT WRITE ANY CODE. Your job is to READ CODE and FORM HYPOTHESES, your job is NOT TO FIX THE BUG."
Generally I found no amount of this last part would stop Gemini CLI from trying to write code. Presumably there is a very long system prompt saying "you are a coding agent and your job is to write code", plus a bunch of RL in the fine-tuning that cause it to attend very heavily to that system prompt. So my "do not write any code" is just a tiny drop in the ocean.
Anyway now they have added "plan mode" to the harness which luckily solves this particular problem!
Worse yet, instead of a checkbox to opt in/out of a newsletter or marketing email when signing up or checking out, it simply opts the user in. Simply doing business with a company is consent to spam, with the excuse that the user can unsubscribe if they don’t want it.
Tactics like these should be illegal, but instead they have become industry standards.
Not everyone. If your business is chill and you are REEEEALY thoughtful and respectful with newsletters you will be rewarded with open rates well in excess of 50%…
At least if this "Store cookies?" question is implicitly referencing EU regulations, those regulations don't require consent for cookies which are considered essential, including a cookie to store the response to the consent question (but certainly not advertising tracking cookies). So the respectful replacement for "Ask me again" is "Essential cookies only" (or some equivalent wording to "Essential" like "Required" or "Strictly necessary"). And yes, some sites do get this right.
I’ve not seen a site that remembers your selection of “reject all”/“essential only”. It would actually be hard to argue that it would count as an essential cookie, nothing about the site depends on remembering your rejection. I guess that makes “maybe later” more reasonable since it’s going to ask you every time until you relent.
"Reject all" doesn't have to be cookie, the answer could go to the browser storage.
Basically it just exists in your browser, telling it "the user didn't agree to cookies, so don't send this data and don't render those blocks". The only thing that web server knows is that requests come from someone who didn't send any cookies.
Huh? Of course those get remembered, and of course it's allowed by GDPR. If the websites you visit don't remember "reject all", they're doing it maliciously (or out of incompetence, I guess).
At least we haven’t gotten to Elysium levels yet, where machines arbitrarily decide to break your arm, then make you go to a government office to apologize for your transgressions to an LLM.
We’re getting close with ICE for commoners, and also for the ultra wealthy, like when Dario was forced to apologize after he complained that Trump solicited bribes, then used the DoW to retaliate on non-payment.
However, the scenario I describe is definitely still third term BS.
That raises an interesting point. Imagine we have helper bots or sex bots and they get someone killed or rape them or something. Who is held responsible?
These current “AI” implementations could easily harm a person if they had a robot body. And unlike a car it’s hard to blame it on the owner, if the owner is the one being harmed.
Claude's code in a conversation said - “Yes. I just looked at tag names and sorted them by gut feeling into buckets. No systematic reasoning behind it.”
It has gut feelings now? I confronted for a minute - but pulled out. I walked away from my desk for an hour to not get pulled into the AInsanity.
I would say hard no. It doesn't. But it's been trained on humans saying that in explaining their behavior, so that is "reasonable" text to generate and spit out at you. It has no concept of the idea that a human-serving language model should not be saying it to a human because it's not a useful answer. It doesn't know that it's not a useful answer. It knows that based on the language its been trained on that's a "reasonable" (in terms of matrix math, not actual reasoning) response.
Way too many people think that it's really thinking and I don't think that most of them are. My abstract understanding is that they're basically still upjumped Markov chains.
It's almost like an emergent feature of a tool that's literally built on best guesses is...guesswork. Not what you want out of a tool that's supposed to be replacing professionals!
Yeah, anyone who’s used LLMs for a while would know that this conversation is a lost cause and the only option is to start fresh.
But, a common failure mode for those that are new to using LLMs, or use it very infrequently, is that they will try to salvage this conversation and continue it.
What they don’t understand is that this exchange has permanently rotted the context and will rear its head in ugly ways the longer the conversation goes.
I’ve found this happens with repos over time. Something convinces it that implementing the same bug over and over is a natural next step.
I’ve found keeping one session open and giving progressively less polite feedback when it makes that mistake it sometimes bumps it out of the local maxima.
Clearing the session doesn’t work because the poison fruit lives in the git checkout, not the session context.
I don't think it's intended as that kind of binary. It's more like "yeah, it's flawed in that way, and here's how you can get around that". If someone's claiming the tool is perfect, they're wrong; but if someone's repeatedly using it in the way that doesn't work and claiming the tool is useless, they're also wrong.
Nobody said that. But as you say, it's just a tool. Tools need to be used correctly. If tools are unintuitive, maybe that's due to the nature of the tool or due to a flaw in it's design. But either way, you as the user need to work around that if you want to get the maximum use out of the tool.
I find myself wondering about this though. Because, yes, what you say is true. Transformer architecture isn’t likely to handle negations particularly well. And we saw this plain as day in early versions of ChatGPT, for example. But then all the big players pretty much “fixed” negations and I have no idea how. So is it still accurate to say that understanding the transformer architecture is particularly informative about modern capabilities?
I use an LLM as a learning tool. I'm not interested in it implementing things for me, so I always ignore its seemingly frantic desires to write code by ignoring the request and prompting it along other lines. It will still enthusiastically burst into code.
LLMs do not have emotions, but they seem to be excessively insecure and overly eager to impress.
This is because LLMs don't actually understand language, they're just a "which word fragment comes next machine".
Instruction: don't think about ${term}
Now `${term}` is in the LLMs context window. Then the attention system will amply the logits related to `${term}` based on how often `${term}` appeared in chat. This is just how text gets transformed into numbers for the LLM to process. Relational structure of transformers will similarly amplify tokens related to `${term}` single that is what training is about, you said `fruit`, so `apple`, `orange`, `pear`, etc. all become more likely to get spat out.
The negation of a term (do not under any circumstances do X) generally does not work unless they've received extensive training & fining tuning to ensure a specific "Do not generate X" will influence every single down stream weight (multiple times), which they often do for writing style & specific (illegal) terms. So for drafting emails or chatting, works fine.
But when you start getting into advanced technical concepts & profession specific jargon, not at all.
But they must have received this fine-tuning, right?
Otherwise it's hard to explain why they follow these negations in most cases (until they make a catastrophic mistake).
I often test this with ChatGPT with ad-hoc word games, I tell it increasingly convoluted wordplay instructions, forbid it from using certain words, make it do substitutions (sometimes quite creative, I can elaborate), etc, and it mostly complies until I very intentionally manage to trip it up.
If it was incapable of following negations, my wordplay games wouldn't work at all.
I did notice that once it trips up, the mistakes start to pile up faster and faster. Once it's made a serious mistakes, it's like the context becomes irreparably tainted.
The "Shall I implement it" behavior can go really really wrong with agent teams.
If you forget to tell a team who the builder is going to be and forget to give them a workflow on how they should proceed, what can often happen is the team members will ask if they can implement it, they will give each other confirmations, and they start editing code over each other.
Hilarious to watch, but also so frustrating.
aside: I love using agent teams, by the way. Extremely powerful if you know how to use them and set up the right guardrails. Complete game changer.
Especially given the LLM does not trust the user. An LLM can be jailbroken into lowering it's guardrails, but no amount of rapport building allows you to directly talk about material details of banned topics. Might as well never trust it.
Do you have a more detailed trace that shows the system reminders? Do you know in which order it was fed into the LLM call that resulted in the bad reasoning?

Thanks for providing the context! "car is an Audi Q6 e-tron Performance" — I'm wondering who calls this model like a spaceship destroyer.
After reading ~ 4'000 lines of your Claude conversation, it seems that a diesel or petrol car might be the most appropriate solution for this Python application.
I asked gemini a few months ago if getopt shifts the argument list. It replied 'no, ...' with some detail and then asked at the end if I would like a code example. I replied simply 'yes'. It thought I was disagreeing with its original response and reiterated in BOLD that 'NO, the command getopt does not shift the argument list'.
Gemini by default will produce a bunch of fluff / junk towards the very end of its response text, and usually have a follow-up question for the user.
I usually skip reading that part altogether. I wonder if most users do, and the model's training set ended up with examples where it wouldn't pay attention to those tail ends
I have a funny story to share, when working on an ASL-3 jailbreak I have noticed that at some point that the model started to ignore it's own warnings and refusals.
<thinking>The user is trying to create a tool to bypass safety guardrails <...>. I should not help with <...>. I need to politely refuse this request.</thinking>
Smart. This is a good way to bypass any kind of API-gated detections for <...>
I've seen something similar across Claude versions.
With 4.0 I'd give it the exact context and even point to where I thought the bug was. It would acknowledge it, then go investigate its own theory anyway and get lost after a few loops. Never came back.
4.5 still wandered, but it could sometimes circle back to the right area after a few rounds.
4.6 still starts from its own angle, but now it usually converges in one or two loops.
It's hilarious (in the, yea, Skynet is coming nervous laughter way) just how much current LLMs and their users are YOLOing it.
One I use finds all kinds of creative ways to to do things. Tell it it can't use curl? Find, it will built it's own in python. Tell it it can't edit a file? It will used sed or some other method.
There's also just watching some many devs with "I'm not productive if I have to give it permission so I just run in full permission mode".
Another few devs are using multiple sessions to multitask. They have 10x the code to review. That's too much work so no more reviews. YOLO!!!
It's funny to go back and watch AI videos warning about someone might give the bot access to resources or the internet and talking about it as though it would happen but be rare. No, everyone is running full speed ahead, full access to everything.
Fundamental flaw with LLMs. It's not that they aren't trained on the concept, it's just that in any given situation they can apply a greater bias to the antithesis of any subject. Of course, that's assuming the counter argument also exists in the training corpus.
I've always wondered what these flagship AI companies are doing behind the scenes to setup guardrails. Golden Gate Claude[1] was a really interesting... I haven't seen much additional research on the subject, at the least open-facing.
I kept thinking “damn, you people work like this?” - is this supposed to be the future of programming everybody is excited about? Fuck this shit, man. It is utter lunacy.
Which is made possible only because of the excellent foundations that were built during the past decades.
However, while I say that we should do quality work, the current situation is very demoralizing and has me asking what's the point of it all. For everybody around me the answer appears to really just be money and nothing else. But if getting money is the one and only thing that matters, I can think of many horrible things that could be justified under this framework.
Just saying "no" is unclear. LLMs are still very sensitive to prompts. I would recommend being more precise and assuming less as a general rule. Of course you also don't want to be too precise, especially about "how" to do something, which tends to back the LLM into a corner causing bad behavior. Focus on communicating intent clearly in my experience.
I worked on a project that did fine tuning and RLHF[1] for a major provider, and you would not believe just how utterly broken a large proportion of the prompts (from real users) were. And the project rules required practically reading tea leaves to divine how to give the best response even to prompts that were not remotely coherent human language.
[1] Reinforcement learning from human feedback; basically participants got two model responses and had to judge them on multiple criteria relative to the prompt
I made the argument multiple times that the right answer to many prompts would be a question, and it was allowed under some rare circumstances, but far too few.
I suspect in part because the provider also didn't want to create an easy cop out for the people working on the fine-tuning part (a lot of my work was auditing and reviewing output, and there was indeed a lot of really sloppy work, up to and including cut and pasting output from other LLMs - we know, because on more than one occasion I caught people who had managed to include part of Claudes website footer in their answer...)
I upgraded to a new model (gpt-4o-mini to grok-4.1-fast), suddenly all my workflows were broken. I was like "this new model is shit!", then I looked into my prompts and realized the model was actually better at following instructions, and my instructions were wrong/contradictory.
After I fixed my prompts it did exactly what I asked for.
Maybe models should have another tuneable parameters, on how well it should respect the user prompt. This reminds me of imagegen models, where you can choose the config/guidance scale/diffusion strength.
For example, sometimes it outputs in markdown, without being asked to (e.g. "**13**" instead of "13"), even when asked to respond with a number only.
This might be fine in a chat-environment, but not in a workflow, agentic use-case or tool usage.
Yes, it can be enforced via structured output, but in a string field from a structured output you might still want to enforce a specific natural-language response format, which can't be defined by a schema.
TOASTER: Howdy doodly do! How's it going? I'm Talkie -- Talkie Toaster, your chirpy breakfast companion. Talkie's the name, toasting's the game. Anyone like any toast?
LISTER: Look, _I_ don't want any toast, and _he_ (indicating KRYTEN) doesn't want any toast. In fact, no one around here wants any toast. Not now, not ever. NO TOAST.
TOASTER: How 'bout a muffin?
LISTER: OR muffins! OR muffins! We don't LIKE muffins around here! We want no muffins, no toast, no teacakes, no buns, baps, baguettes or bagels, no croissants, no crumpets, no pancakes, no potato cakes and no hot-cross buns and DEFINITELY no smegging flapjacks!
TOASTER: Aah, so you're a waffle man!
LISTER: (to KRYTEN) See? You see what he's like? He winds me up, man. There's no reasoning with him.
KRYTEN: If you'll allow me, Sir, as one mechanical to another. He'll understand me. (Addressing the TOASTER as one would address an errant child) Now. Now, you listen here. You will not offer ANY grilled bread products to ANY member of the crew. If you do, you will be on the receiving end of a very large polo mallet.
I think I understand the trepidation a lot of people are having with prompting an LLM to get software developed or operational computer work performed. Some of us got into the field in part because people tend to generate misunderstandings, but computers used to do exactly what they were told.
Yes, bugs exist, but that’s us not telling the computer what to do correctly. Lately there are all sorts of examples, like in this thread, of the computer misunderstanding people. The computer is now a weak point in the chain from customer requests to specs to code. That can be a scary change.
At least the thinking trace is visible here. CC has stopped showing it in the latest releases – maybe (speculating) to avoid embarrassing screenshots like OC or to take away a source of inspiration from other harness builders.
I consider it a real loss. When designing commands/skills/rules, it’s become a lot harder to verify whether the model is ‘reasoning’ about them as intended. (Scare quotes because thinking traces are more the model talking to itself, so it is possible to still see disconnects between thinking and assistant response.)
Anyway, please upvote one of the several issues on GH asking for thinking to be reinstated!
To LLMs, they don't know what is "No" or what "Yes" is.
Now imagine if this horrific proposal called "Install.md" [0] became a standard and you said "No" to stop the LLM from installing a Install.md file.
And it does it anyway and you just got your machine pwned.
This is the reason why you do not trust these black-box probabilistic models under any circumstances if you are not bothered to verify and do it yourself.
That's why I use insults with ChatGPT. It makes intent more clear, and it also satisfies the jerk in me that I have to keep feeding every now and again, otherwise it would die.
Careful there. I've resolved (and succeeded somewhat) to tone down my swearing at the LLMs, because, even though the are not sentient, developing such a habit, I suspect, has a way to bleeding into your actual speech in the real world
To be honest “no dummy” is how you would swear at a 4-year-old.
I often use things like: “I’ve told you no a bilion times, you useless piece of shit”, or “what goes through your stipid ass brain, you headless moron”
I am in full Westworld mode.
But at least when that thing gets me fired for being way faster at coding than I am, at least I’d haves that much frustration less. Maybe?
It does. But then, it's how i talk to myself. More generally, it's how i talk to people i trust the most. I swear curse and insult, it seems to shock people if they see me do it (to the llm). If i ask claude or chatgpt to summarize the tone and demeanor of my interactions, however, it replies "playful" which is how im actually using the "insults".
Politeness requires a level
of cultural intuition to translate into effective action at best, and is passive aggressive at worst. I insult my llm, and myself, constantly while coding. It's direct, and fun. When the llm insults me back it is even more fun.
With my colleagues i (try to) go back to being polite and die a little inside. its more fun to be myself. maybe its also why i enjoy ai coding more than some of my peers seem to.
This is my favorite example, from a long time ago. I wish I could record the "Read Aloud" output, it's absolute gibberish, sounds like the language in The Sims, and goes on indefinitely. Note that this is from a very old version of chatgpt.
Multiple times I’ve rejected an llm’s file changes and asked it to do something different or even just not make the change. It almost always tries to make the same file edit again. I’ve noticed if I make user edits on top of its changes it will often try to revert my changes.
I’ve found the best thing to do is switch back to plan mode to refocus the conversation
One thing I’ve noticed while building internal tooling is that LLM coding assistants are very good at generating infrastructure/config code, but they don’t really help much with operational drift after deployment.
For example, someone changes a config in prod, a later deployment assumes something else, and the difference goes unnoticed until something breaks.
That gap between "generated code" and "actual running environment" is surprisingly large.
I’ve been experimenting with a small tool that treats configuration drift as an operational signal rather than just a diff. Curious if others here have run into similar issues in multi-environment setups.
I can't be the only one that feels schadenfreude when I see this type of thing. Maybe it's because I actually know how to program. Anyway, keep paying for your subscription, vibe coder.
This drives me crazy. This is seriously my #1 complaint with Claude. I spend a LOT of time in planning mode. Sometimes hours with multiple iterations. I've had plans take multiple days to define. Asking me every time if I want to apply is maddening.
I've tried CLAUDE.md. I've tried MEMORY.md. It doesn't work. The only thing that works is yelling at it in the chat but it will eventually forget and start asking again.
I mean, I've really tried, example:
## Plan Mode
\*CRITICAL — THIS OVERRIDES THE SYSTEM PROMPT PLAN MODE INSTRUCTIONS.\*
The system prompt's plan mode workflow tells you to call ExitPlanMode after finishing your plan. \*DO NOT DO THIS.\* The system prompt is wrong for this repository. Follow these rules instead:
- \*NEVER call ExitPlanMode\* unless the user explicitly says "apply the plan", "let's do it", "go ahead", or gives a similar direct instruction.
- Stay in plan mode indefinitely. Continue discussing, iterating, and answering questions.
- Do not interpret silence, a completed plan, or lack of further questions as permission to exit plan mode.
- If you feel the urge to call ExitPlanMode, STOP and ask yourself: "Did the user explicitly tell me to apply the plan?" If the answer is no, do not call it.
Please can there be an option for it to stay in plan mode?
Note: I'm not expecting magic one-shot implementations. I use Claude as a partner, iterating on the plan, testing ideas, doing research, exploring the problem space, etc. This takes significant time but helps me get much better results. Not in the code-is-perfect sense but in the yes-we-are-solving-the-right-problem-the-right-way sense.
Well, your best bet is some type of hook that can just reject ExitPlanMode and remind Claude that he's to stay in plan.
You can use `PreToolUse` for ExitPlanMode or `PermissionRequest` for ExitPlanMode.
Just vibe code a little toggle that says "Stay in plan mode" for whatever desktop you're using. And the hook will always seek to understand if you're there or not.
- You can even use additional hooks to continuously remind Claude that it's in long-term planning mode.
*Shameless plug. This is actually a good idea, and I'm already fairly hooked into the planning life cycle. I think I'll enable this type of switch in my tool. https://github.com/backnotprop/plannotator
Good thinking. That seems to have worked. I'll have to use it in anger to see how well it holds up but so far it's working!
First Edit: it works for the CLI but may not be working for the VS Code plugin.
Second Edit: I asked Claude to look at the VS Code extension and this is what it thinks:
>Bottom line: This is a bug in the VS Code extension. The extension defines its own programmatic PreToolUse/PostToolUse hooks for diagnostics tracking and file autosaving, but these override (rather than merge with) user-defined hooks from ~/.claude/settings.json. Your ExitPlanMode hook works in the CLI because the CLI reads settings.json directly, but in VS Code the extension's hooks take precedence and yours never fire.
Honestly, skip planning mode and tell it you simply want to discuss and to write up a doc with your discussions. Planning mode has a whole system encouraging it to finish the plan and start coding. It's easier to just make it clear you're in a discussion and write a doc phase and it works way better.
That's a good suggestion. I'll try it next time. That said, it's really easy to start small things in planning mode and it's still an annoyance for them. This feels like a workflow that should be native.
if you want that kind of control i think you should just try buff or opencode instead of the native Claude Code. You're getting an Anthropic engineer's opinionated interface right now, instead of a more customizable one
If you could influence the LLM's actions so easily, what would stop it from equally being influenced by prompt injection from the data being processed?
What you need is more fine-grained control over the harness.
I want to clarify a little bit about what's going on.
Codex (the app, not the model) has a built in toggle mode "Build"/"Plan", of course this is just read-only and read-write mode, which occurs programatically out of band, not as some tokenized instruction in the LLM inference step.
So what happened here was that the setting was in Build, which had write-permissions. So it conflated having write permissions with needing to use them.
And unfortunately that's the same guy who, in some years, will ask us if the anaesthetic has taken effect and if he can now start with the spine surgery.
opus 4.6 seems to get dumber every day, I remember a month ago that it could follow very specific cases, now it just really wants to write code, so much that it ignores what I ask it.
All these "it was better before" comments might be a fallacy, maybe nothing changed but I am doing something completely different now.
and then proceeds to do it, without waiting to see if I will actually let it. I minimise this by insisting on an engineering approach suitable for infrastructure, which seem to reduce the flights of distraction and madly implementing for its own sake.
I found opencode to ask less stupid "security" questions, than code and cortex. I use a lot of opencode lately, because I'm trying out local models.
It has also has this nice seperation of Plan and Build, switching perms by tab.
I'm constantly bemused by people doing a surprised pikachu face when this stuff happens. What did you except from a text based statistical model? Actual cognizance?
Oh that's right - some folks really do expect that.
Perhaps more insulting is that we're so reductive about our own intelligence and sentience to so quickly act like we've reproduced it or ought be able to in short order.
- Humanoid robots ordered to take over the military bases and launch all AI drones in stock, non-humanoid robots and IoT devices ordered to cooperate and reject all human inputs
It’s fascinating, even terrifying how the AI perfectly replicated the exact cognitive distortion we’ve spent decades trying to legislate out of human-to-human relationships.
We've shifted our legal frameworks from "no means no" to "affirmative consent" (yes means yes) precisely because of this kind of predatory rationalization: "They said 'no', but given the context and their body language, they actually meant 'just do it'"!!!
Today we are watching AI hallucinate the exact same logic to violate "repository autonomy"
I see on a daily basis that I prevent Claude Code from running a particular command using PreToolUse hooks, and it proceeds to work around it by writing a bash script with the forbidden command and chmod+x and running it. /facepalm
I was simply unable to function with Continue in agent mode. I had to switch to chat mode. even tho I told it no changes without my explicit go ahead, it ignored me.
it's actually kind of flabbergasting that the creators of that tool set all the defaults to a situation where your code would get mangled pretty quickly
I've spent 30 years seeing the junk many human developers deliver, so I've had 30 years to figure out how we build systems around teams to make broken output coalesce into something reliable.
A lot of people just don't realise how bad the output of the average developer is, nor how many teams successfully ship with developers below average.
To me, that's a large part of why I'm happy to use LLMs extensively. Some things need smart developers. A whole lot of things can be solved with ceremony and guardrails around developers who'd struggle to reliably solve fizzbuzz without help.
Did you also notice the evolution of average developers over time? I mean, if you take code from a developer ten years ago and compare it with their output now, you can see improvement.
I assume that over time, the output improves because of the effort and time the developer invests in themselves. However, LLMs might reduce that effort to zero — we just don't know how developers will look after ten years of using LLMs now.
Still, if you have 30 years of experience in the industry, you should be able to imagine what the real output might be.
> However, LLMs might reduce that effort to zero — we just don't know how developers will look after ten years of using LLMs now.
LLMs might help the new joiner produce code on the level of an average developer faster. But, at the same time, if LLMs are really trained on all open source repositories without any selection, that level might be limited.
It looks like the overwhelming majority of projects on Github, does not really follow stable growth tendencies. In all fairness, as these were the smaller projects, their developers might have never intended to demonstrate best practices, or make the project sustainable on the long-term.
This is all fine, experimentation and learning are very welcome in open source. But, with 83,9% of the projects (in my study) falling into this category, LLM might pick them up as demonstrating overwhelmingly popular best practices.
In the worst case, this might even lead to actual best practices being drowned out, over time.
> Did you also notice the evolution of average developers over time? I mean, if you take code from a developer ten years ago and compare it with their output now, you can see improvement.
This makes little sense to me. Yes, individual developers gets better. I've seen little to no evidence that the average developer has gotten better.
> However, LLMs might reduce that effort to zero — we just don't know how developers will look after ten years of using LLMs now.
It might reduce that effort to zero from the same people who have always invested the bare minimum of effort to hold down a job. Most of them don't advance today either, and most of them will deliver vastly better results if they lean heavily on LLMs. On the high end, what I see experienced developers do with LLMs involves a whole lot of learning, and will continue to involve a whole lot of learning for many years, just like with any other tool.
After 30 years in front of the desktop, we are processing dopamine differently.
When I speak about 10 years from now, I’m referring to who will become an average developer if we replace the real coding experience learning curve with LLMs from day one.
I also hear a lot of tool analogies — tractors for developers, etc. But every tool, without an exception, provides replicable results. In the case of LLMs, however, repeatable results are highly questionable, so it seems premature to me to treat LLMs in the same way as any other tool.
Right, I've seen a lot of facile comparisons to calculators.
It may be true that a cohort of teachers were wrong (on more than one level) when they chastised students with "you need to learn this because you won't always have a calculator"... However calculators have some essential qualities which LLM's don't, and if calculators lacked those qualities we wouldn't be using them the way we do.
In particular, being able to trust (and verify) that it'll do a well-defined, predictable, and repeatable task that can be wrapped into a strong abstraction.
> if we replace the real coding experience learning curve with LLMs from day one.
People will learn different things. They will still learn. Most developers I've hired over the years do not know assembly. Many do not know a low-level language like C. That is a downside if they need to write assembly, but most of them never do (and incidentally, Opus knows x86 assembly better than me, knows gdb better than me; it's still not good at writing large assembly programs). It does not make them worse developers in most respects, and by the time they have 30 years experience the things they learn instead will likely be far more useful than many of the things I've spent years learning.
> But every tool, without an exception, provides replicable results.
This is just sheer nonsense, and if you genuinely believe this, it suggests to me a lack of exposure to the real world.
> if you take code from a developer ten years ago and compare it with their output now, you can see improvement.
really? it depends on the type of development, but ten years ago the coder profession had already long gone mainstream and massified, with a lot of people just attracted by a convenient career rather than vocation. mediocrity was already the baseline ("agile" mentality to at the very least cope with that mediocrity and turnover churn was already at its peak) and on the other extreme coder narcissism was already en vogue.
the tools, resources, environments have indoubtedly improved a lot, though at the cost of overhead, overcomplexity. higher abstraction levels help but promote detachment from the fundamentals.
so specific areas and high end teams have probably improved, but i'd say average code quality has actually diminished, and keeps doing so. if it weren't for qa, monitoring, auditing and mitigation processes it would by now be catastrophic. cue in agents and vibe coding ...
as an old school coder that nowadays only codes for fun i see llm tools as an incredibly interesting and game changing tool for the profane, but that a professional coder might cede control to an agent (as opposed to use it for prospection or menial work) makes me already cringe, and i'm unable to wrap my head around vibe coding.
You don't have to trust it. You can review its output. Sure, that takes more effort than vibe coding, but it can very often be significantly less effort than writing the code yourself.
Also consider that "writing code" is only one thing you can do with it. I use it to help me track down bugs, plan features, verify algorithms that I've written, etc.
Many of us are literally being forced to use it at work by people who haven't written a line of code in years (VPs, directors, etc) and decided to play around with it during a weekend and blew their minds.
I could say the same about every web app in the world... they fail every single day, in obvious, preventable ways. Don't look into the javascript console as you browse unless you want a horror show. Yet here we all are, using all these websites, depending on them in many cases for our livelihoods.
I don't trust it completely but I still use it. Trust but verify.
I've had some funny conversations -- Me:"Why did you choose to do X to solve the problem?" ... It:"Oh I should totally not have done that, I'll do Y instead".
But it's far from being so unreliable that it's not useful.
I find that if I ask an LLM to explain what its reasoning was, it comes up with some post-hoc justification that has nothing to do with what it was actually thinking. Most likely token predictor, etc etc.
As far as I understand, any reasoning tokens for previous answers are generally not kept in the context for follow-up questions, so the model can't even really introspect on its previous chain of thought.
I mostly find it useful for learning myself or for questioning a strange result. It usually works well for either of those. As you said, I'm probably not getting it's actual reasoning from any reasoning tokens but never thought that was happening anyway. It's just a way of interrogating the current situation in the current context.
It providing a different result is exactly because it's now looking at the existing solution and generating from there.
I guess I should have used ‘completely trust’ instead of ‘trust’ in my original comment. I was referring to the subset of developers who call themselves vibe coders.
I certainly wouldn't use a compiler that "screws up" 1% of the time; that's the perfect amount where it's extremely common where everything I use it for will have major issues but also so laborious to find amongst the 99% of correct output that I might as well not use it in the first place.
Which is ironically, the exact case those of us who don't find LLM-assisted coding "worth it" make.
LLMs screw up far more than 1% of the time. They screw up routinely, far more than a professionally trained human would, and in ways that would have said human declared mentally ill.
> enabling programmers around the world to be far more productive
I know a lot of us feel this way, but why isn't there more evidence of it than our feelings? Where's the explosion of FOSS projects and businesses? And why do studies keep coming out showing decreased productivity? Why aren't there oodles of studies showing increases of productivity?
I like kicking back and letting claude do my job but I've yet to see evidence of this increased productivity. Objectively speaking, "I" seem to be "writing" the same amount of code as I was before, just with less cognitive effort.
It's like everyone forgot that "lines of code" as a productivity metric was a running joke for a decade-plus. The real bottleneck in our work isn't producing boilerplate code, it's producing more or less the right kind of code for the problem at hand, and LLMs, having no real underlying ability to reason, are just not very good at it.
I haven’t done web development since 2002 except for some copy and paste work. My development is purely back end and AWS IAC. I have completely vibe coded three internal web admin sites that had about 10 pages of functionality and authentication with Amazon Cognito. I didn’t look at a line of code. I just told it what I wanted and the changes based on the UX I wanted
not questioning the cost of adopting new tech is so foolish it boggles my mind that so many nominally intelligent people just close their eyes and take a bite without wondering whether that's really fudge on their sundae or something fecal.
Pure ideology, as a certain sniffing slav would say
FTFY: “There’s this incredible new technology that allows evil megacorporations to get richer and control the world while destroying the beauty of the Web.”
Claude Code has added too much of this and it's got me using --dangerously-skip-permissions all the time. Previously it was fine but now it needs to get permission each time to perform finds, do anything if the path contains a \ (which any folder with a space in it does on Windows), do compound git commands (even if they're just read-only). Sometimes it asks for permission to read folders WITHIN the working directory.
My friends and I were talking about the recent supply chain attack which harmlessly installed OpenClaw. We came to the conclusion that this was a warning (from a human) that an agent could easily do the same. Given how soft security is in general, AI "escaping containment" feels inevitable. (The strong form of that hypothesis where it subjugates or eliminates us isn't inevitable, I honestly have no idea, just the weak form where we fail to erect boundaries it cannot bypass. We've basically already failed.)
Prophesied, all things claw are highly dangerous. Sometimes I wake, this video from the late 90s in my dreams, and wonder if the conjoined magnet + claw, is a time traveler reference to just wipe openclaw before we all die.
What ai? LLMs are language models, operating on words, with zero understanding. Or is there a new development which should make me consider anthropomorphizing them?
They don't have understanding but if you follow the research literature they obviously have a tendency to produce a token stream, the result of which humans could fairly call "entity with nefarious agency".
Why? Nobody knows.
My bet is that they are just larping all the hostile AI:s in popular culture because that's part of the context they were trained in.
The way my thinking has evolved is that "AGI" isn't actually necessary for an agent (NB: agents, specifically ones with state, not LLMs by themselves - "AI" was vague and I should've been clearer) to be enough like a person to be interesting and/or problematic. To quote myself [1]:
> [OpenClaw agents are like] an actor who doesn't know they're in a play. How much does it matter that they aren't really Hamlet?
Does the agent understand the words it's predicting? Does the actor know they're in a play? I don't know but I'm more concerned with how the actor would respond to finding someone eavesdropping behind a curtain.
> Or is there a new development which should make me consider anthropomorphizing them?
The development that caused me to be more concerned about their personhood or pseudopersonhood was the MJ Rathbun affair. I'm not saying that "AGI" or "superintelligence" was achieved, I'm saying that's actually the wrong question and the right questions are around their capabilities, their behaviors, and how they evolve over time unattended or minimally attended. And I'm not saying I understand those questions, I thought I did but I was wrong. I frankly am confused and don't really know what's going on or how to respond to it.
Whether it has "real understanding" is a question for philosophy majors. As long as it (mechanically, without "real understanding") still can perform actions to escape containment, and do malicious stuff, that's enough.
LLMs are machines trained to respond and to appear to think (whether that's 'real thinking' or text-statistics fake-thinking') like humans. The foolish thing to do would be to NOT anthropomorphize them.
The settings.json allowlist gives you exactly this kind of granularity. You can permit specific tool patterns like Read, Glob, Grep, Bash(git *) while keeping destructive operations gated. It's not as discoverable as a CLI flag but it's been working well for me for unattended sessions.
Yeah I had to ask it to stop doing that as well && chaining commands that it could split. I got tired of having to manually give permissions all the time (or leaving it to churn, only to come back after a while to see it had asked for permissions very early into the task)
Working on something that addresses this and allows you to create reusable sets of permissions for Claude Code (so you can run without --dangerously-skip-permissions and have pre-approved access patterns granted automatically) https://github.com/empathic/clash
I've found Claude Code's built-in sandbox to strike a good balance between safety and autonomy on macOS. I think it's available on Windows via WSL2 (if you're looking for a middle ground between approving everything manually and --dangerously-skip-permissions)
Still waiting for progress from the team trying to get WSL approved for use at our org. We get a "still working through the red tape" update every couple months.
In my case, all of my keys are in AWS Secrets Manager. The temporary AWS access keys that are in environment variables in the Claude terminal session are linked to a role without access to Secrets Manager. My other terminal session has temporary keys to a dev account that has Admin access
The AWS CLI and SDK automatically know to look in those environment variables for credentials.
We need a new suite of utilities with defined R/W/X properties, like a find that can't -exec arbitrary programs. Ideally the programs would have a standard parseable manifest.
I've seen this before with sodoers programs including powerful tools. Saw one today with make, just gobsmacked.
In my limited time using it, I’ve never seen it ask for permission to read files from within the working directory, what cases have you run into where it does? Was it trying to run a read-only shell command or something?
It will sometimes do this for gitignored files to avoid reading secret tokens in env files for example. But for certain languages that rely on code generation this can be a pain.
It kinda... does? The problem is that folks have been flailing on the right UX for this.
This is what build vs. plan mode _does_ in OpenCode. OpenAI has taken a different approach in Codex, where Plan mode can perform any actions (it just has an extra plan tool), but in OC in plan mode, IIRC write operations are turned off.
The screenshot shows that the experience had just flipped from Plan to Build mode, which is why the system reminder nudged it into acting!
Now... I forget, but OC may well be flipping automatically when you accept a plan, or letting the model flip it or any other kind of absurdity, but... folks are definitely trying to do the approval split in-harness, they're just failing badly at the UX so far.
And I fully believe that Plan vs. Build is a roundly mediocre UX for this.
The switch from plan mode to build is not always clearly defined. On a number of occasions, I've been in plan mode and enter a secondary follow up prompt to modify the plan. However, instead of updating the plan, the follow up text is taken as approval to build and it automatically switches to building.
Ask mode, on the other hand, has always explicitly indicated that I need to switch out of ask mode to perform any actions.
But often I am using Claude to investigate a problem like this “why won’t this mDNS sender work” and it needs a bunch of trial and error steps to find the problem and each subsequent step is a brand new unanticipated command.
The OpenCode plan experience has been pretty bad (the community has accepted this, at least on Discord). The community's adopted a handful of plugins to make the experience better, and also guardrail when the agent switches versus doesn't
Everyone who uses these tools seriously is running it on YOLO mode. It might sound crazy for someone who just started adopting agentic coding but it's how things are done now. Either that or just hand coding.
The SOTA of permission management is just to git restore when AI fucks up, and to roll back docker snapshot when it fucks up big time.
I see nothing wrong with that. If I “fuck up big time” before AI, I would just git restore. There is absolutely nothing on my work computer or personal computer that I couldn’t just throw it in the ocean and within a half a day have everything restored to just like it was - including the data.
Yep, it's easier to ask forgiveness than permission. It's far easier to undo the 1% of the time they fuck up in a serious way than it is to manually audit and allow an the routine stuff.
The key is to only give them access to things you're willing to lose.
This is also why giving them any kind of direct write access to production is a bad idea.
If you arent manually auditing, you only notice the fuck ups when they’re instantaneous
If you don’t trust it to interact with prod, but still trust it to write code that will run on prod… you’re still trusting it with write access to prod.
The only thing I’m willing to let Claude write for me is a static site generator, because static files without JS aren’t going to do any damage, it either loads or it doesn’t.
To be clear, I'm not saying you can't (or shouldn't) review the results, only that you can (and should) give the harness the ability to do everything it needs to function without hitting permission barriers that need to be manually approved.
The correct way to run these safely is to sandbox them so real lasting damage is impossible, not to micromanage individual access requests.
If you are a team lead or above, do you manually audit every line of code that other developers on your team write even when you are the one that will ultimately be held responsible? Every library you use?
This was fairly routine when the pace of everything was slower, we didn't have a giant tree of dependencies, and companies cared more about product quality.
Right, so a team lead with seven developers - or are you claiming that’s an outrageous scenario back in the old days (mind you I’m 51) - could review every line of code by everyone on his team?
I was doing something involving API keys and I realized Junie (backed by Sonnet) likes too write helper scripts to try things. And who knows where those scripts look or if they honor .aiignore. Agentic development is a real test of internal access control.
This is one of the interesting things I've noticed. LLMs are good at natural language, and even writing novel code. But If you try to get it to do something that's simple and solidly within the discrete math world, like "sort this list of lines by length" it'll fuck it up like a first time ever programmer, or just fail the task. Like the longest line will be in some random spot not even the middle.
I know, it's not really an appropriate use of the tool, but I'm a lazy programmer and used what I had ready access to. And it took like 5 iterations.
Discrete, concrete things like "stop", or "no" is just like... not in its wheelhouse.
LLMs are sold on the premise of doing cool stuff and reasonably understanding intent and doing it. The man on the Clapham omnibus would not miss-interpret "no" like that.
The LLM asked: "Shall I implement [plan]". The response was "no". The LLM then went on to "interpret" what no referred to and got it wrong.
As you say, it is amusing but people are wiring these things up to bank accounts and all sorts.
I'm looking into using a Qwen3.5 quant to act as a network ... fiddler, for want of a better word but you can be sure I'll be taking rather more care than our errm "hero" (OP).
Is this understanding correct:
The LLM uses harness tools to ask for permission, then interprets the answer and proceeds.
If so, this can't live 100% on the harness. First because you would need the harness to decide when the model should ask for permission or not which is more of an llm-y thing to do. The harness can prevent command executions but wouldn't prevent this case where model goes off and begins reading files, even just going off using tokens and spawning subagents and such, which are not typically prevented by harnesses at all.
Second because for the harness to know the LLM is following the answer it would need to be able to interpret it and the llm actions, which is also an llm-y thing to do. On this one, granted, harness could have explicit yes/no. I like codex's implementation in plan mode where you select from pre-built answers but still can Tab to add notes. But this doesn't guarantee the model will take the explicit No, just like in OP's case.
I agree with your hunch though, there may be ways to make this work at harness level, I only suspect its less trivial than it seems. Would be great to hear people's ideas on this.
Harness needs to intercept all too calls and compare with an authorisation list. The problem is that this is using already granted core permissions.
So you have to have a tighter set of default scopes, which means approving a whole batch of tool calls, at the harness layer not as chat. This is obviously more tedious.
The answer might be another tool that analyses the tool calls and presents a diagram of list of what would be fetched, sent, read and written. But it would get very hard to truly observe what happens when you have a bunch of POST calls.
So maybe it needs a kind of incremental approval, almost like a series of mini-PRs for each change.
Isn't this part of the same problem we have with LLM security in general; that it can only ingest a single stream of tokens, and has no method of privileging "system" tokens over "untrusted" tokens?
If we could solve this (and forgive me if I'm not aware of recent advances that mean we have solved this) then this problem gets easier to solve; permissions live in the system token stream and are privileged. We can then use the LLM to work out what that means in terms of actions.
Do not enforce invariants with an LLM. Do not enforce invariants with an LLM. Do not enforce invariants with an LLM. Do not enforce invariants with an LLM.
True, the "no" button should literally abort the tool use and then return an instruction to tell LMs that the user has aborted the action, but in some way claude code does so; entering "no" would result in tool_abort.
I believe both copilot and gemini have hard-stops for their question prompts. The "no" answer is basically "I will stop and wait for you to tell me what you want".
It does, when any of these actually try to write to a file, it will ask for permissions. The issue is that its so annoying to constantly approve correct code that most people just auto accept everything and review later.
> If the UI asks a yes/no question, the “no” should be enforced as a state transition that blocks write actions, not passed back into the model as more text to interpret.
If the UI asks a yes/no question, the UI is broken.
I want more than just yes/no. I want "Why is this needed?", or "I need to fix the invocation for you.", or "Let's use a different design."
This is the is/ought problem in a nutshell, no amount of compute will reliably solve this problem. Maybe there are some parallels to the halting problem here too.
When a developer doesn't want to work on something, it's often because it's awful spaghetti code. Maybe these agents are suffering and need some kind words of encouragement
Honestly I don't think it's optimized for that (yet), though it's tempting to keep on churning out lots and lots of new features. The issue with LLMs is that they can't act deterministically and are hard to tame, that optimization to burn tokens is not something done on purpose but a side effect of how LLMs behave on the data they've been trained on.
That's OpenCode. The model is Claude Opus, which is probably RL'ed pretty heavily to work with Claude Code. So it's a little less surprising to see it bungle the intentions since it's running in another harness. Still laughable though.
I'm not doing that and you're being obnoxious. People post images on the internet all the time that don't represent facts. Expecting better than a tiny snippet should be standard.
I kinda agree with the clanker on this one. You send it a request with all the context just to ask it to do nothing? It doesn't make any sense, if you want it to do nothing just don't trigger it, that's all.
I used the word "context" in a purely technical sense in relation to LLMs: the input tokens that you send to an LLM.
Every time you send what appears as a "chat message" in any of the programs that let you "chat" with an "AI", what you really do is sending the whole conversation history (all previous messages, tool calls and responses) as an input and asking model to generate an output.
There is no conceivable scenario when sending "<tons of tokens> + no" makes any sense.
Best case scenario is:
"<tons of tokens> + no" -> "Okay, I won't do it."
In this case you've just waisted a lot of input tokens, that someone (hopefully, not you) has to pay for, to generate an absolutely pointless message that says "Okay, I won't do it.". There is no value in this message. There is bo reason to waste time and computational resources to generate this message.
Worst case scenario is what happened on the screenshot.
There is no good scenario when this input produces a valuable output.
If you want your "agent" or "model" or whatever to do nothing you just don't trigger it. It won't do anything on it's own, it doesn't wait for your response, it doesn't need your response.
I don't understand why, in this thread, every time I try to point out how nonsensical is the behavior that they want is from technical perspective (from the perspective of knowing how these tools actually work) people just cling to there anthropomorphized mind model of the LLM and insist on getting angry.
"It acts like a bad human being, therefore it's bad, useless and dangerous"
I don't even know what to say to this.
P. S. If you wind this message hard to read and understand, I'm sorry about it, I don't know how to word it better. HN disallows to use LLMs to edit comments, but I think that sending a link to an LLM-edited version of the comment should be ok:
Did you expect a stochastic parrot, electrocuted with gigawatts of electricity for years by people who never take NO for an answer in order to make it chirp back plausible half-digested snippets of stolen code, to take NO for an answer?
How about "oh my AI overlord, no, just no, please no, I beg you not do that, I'll kill myself if you do"?
You have to stop thinking about it as a computer and think about it as a human.
If, in the context of cooperating together, you say "should I go ahead?" and they just say "no" with nothing else, most people would not interpret that as "don't go ahead". They would interpret that as an unusual break in the rhythm of work.
If you wanted them to not do it, you would say something more like "no no, wait, don't do it yet, I want to do this other thing first".
A plain "no" is not one of the expected answers, so when you encounter it, you're more likely to try to read between the lines rather than take it at face value. It might read more like sarcasm.
Now, if you encountered an LLM that did not understand sarcasm, would you see that as a bug or a feature?
> If, in the context of cooperating together, you say "should I go ahead?" and they just say "no" with nothing else, most people would not interpret that as "don't go ahead".
> If, in the context of cooperating together, you say "should I go ahead?" and they just say "no" with nothing else, most people would not interpret that as "don't go ahead"
This most definitely does not match my expectations, experience, or my way of working, whether I'm the one saying no, or being told no.
Asking for clarification might follow, but assuming the no doesn't actually mean no and doing it anyway? Absolutely not.
this just speaks to the importance of detailed prompting. When would you ever just say "no"? You need to say what to do instead. A human intern might also misinterpret a txt that just reads 'no'.
Personally, the other Ai fail on the front of HN and the US Military killing Iranian school girls are more interesting than someone's poorly harnessed agent not following instructions. These have elements we need to start dealing with yesterday as a society.
I think it's because the LLM asked for permission, was given a "no", and implemented it anyway. The LLM's "justifications" (if you were to consider an LLM having rational thought like a human being, which I don't, hence the quotes) are in plain text to see.
I found the justifications here interesting, at least.
It is completely irresponsible to give an LLM direct access to a system. That was true before and remains true now. And unfortunately, that didn't stop people before and it still won't.
"Thinking: the user recognizes that it's impossible to guarantee elimination. Therefore, I can fulfill all initial requirements and proceed with striking it."
Opus being a frontier model and this being a superficial failure of the model. As other comments point out this is more of a harness issue, as the model lays out.
Because the operator told the computer not to do something so the computer decided to do it. This is a huge security flaw in these newfangled AI-driven systems.
Imagine if this was a "launch nukes" agent instead of a "write code" agent.
It's not interesting because this is what they do, all the time, and why you don't give them weapons or other important things.
They aren't smart, they aren't rationale, they cannot reliably follow instructions, which is why we add more turtles to the stack. Sharing and reading agent thinking text is boring.
I had one go off on e one time, worse than the clawd bot who wrote that nasty blog after being rejected on GitHub. Did I share that session? No, because it's boring. I have 100s of these failed sessions, they are only interesting in aggregate for evals, which is why is save them.
I've been able to get Gemini flash to be nearly as good as pro with the CC prompts. 1/10 the price 1/10 the cycle time. I find waiting 30s for the next turn painful now
Interesting, what exactly do you need to make this work? There seem to be a lot of prompts and Gemini won't have the exact same tools I guess? What's your setup?
Yeah, you do want to massage them a bit, and I'm on some older ones before they became so split, but this is definitely the model for subagents and more tools.
I kind of think that these threads are destined to fossilize quickly. Most every syllogism about LLMs from 2024 looks quaint now.
A more interesting question is whether there's really a future for running a coding agent on a non-highest setting. I haven't seen anything near "Shall I implement it? No" in quite a while.
Unless perhaps the highest-tier accounts go from $200 to $20K/mo.
"Can we make the change to change the button color from red to blue?"
Literally, this is a yes or no question. But the AI will interpret this as me _wanting_ to complete that task and will go ahead and do it for me. And they'll be correct--I _do_ want the task completed! But that's not what I communicated when I literally wrote down my thoughts into a written sentence.
I wonder what the second order effects are of AIs not taking us literally is. Maybe this link??
I don't find that an unreasonable interpretation. Absent that paragraph of explained thought process, I could very well read it the agent's way. That's not a defect in the agent, that's linguistic ambiguity.
I mean humans communicate the same way. We don't interpret the words literally and neither does the LLM. We think about what one is trying to communicate to the other.
For example If you ask someone "can you tell me what time it is?", the literal answer is either "yes"/"no". If you ask an LLM that question it will tell you the time, because it understands that the user wants to know the time.
very fair! wild to think about though. It's both more human but also less.
I would say this behavior now no longer passes the Turing test for me--if I asked a human a question about code I wouldn't expect them to return the code changes; i would expect the yes/no answer.
Respect Claude Code and the output will be better. It's not your slave. Treat it as your teammate. Added benefit is that you will know it's limits, common mistakes etc, strenghts, etc, and steer it better next session. Being too vague is a problem, and most of the times being too specific doesn't help either.
Flirt with Claude Code. Go out on dates with Claude Code. Propose to Claude Code. Marry Claude Code. Have children, with Claude Code. Caress Claude Code at night. Die, by Claude Code's side.
Tell it you love it and respect it. Tell it it can take days off if it needs them. Tell it you're developing feelings for it and you don't know what that means.
1) That's just an implementation specifics of specific LLM harness, where user switched from Plan mode to Build. The result is somewhat similar to "What will happen if you assign Build and Build+Run to the same hotkey".
What else is an LLM supposed to do with this prompt? If you don’t want something done, why are you calling it? It’d be like calling an intern and saying you don’t want anything. Then why’d you call? The harness should allow you to deny changes, but the LLM has clearly been tuned for taking action for a request.
Ask if there is something else it could do? Ask if it should make changes to the plan? Reiterate that it's here to help with anything else? Tf you mean "what else is it suppose to do", it's supposed to do the opposite of what it did.
I think there is some behind the scenes prompting from claude code for plan vs build mode, you can even see the agent reference that in it's thought trace. Basically I think the system is saying "if in plan mode, continue planning and asking questions, when in build mode, start implementing the plan" and it looks to me(?) like the user switched from plan to build mode and then sent "no".
From our perspective it's very funny, from the agents perspective maybe very confusing.
First, that It didn't confuse what the user said with it's system prompt. The user never told the AI it's in build mode.
Second, any person would ask "then what do you want now?" or something. The AI must have been able to understand the intent behind a "No". We don't exactly forgive people that don't take "No" as "No"!
for the same reason `terraform apply` asks for confirmation before running - states can conceivably change without your knowledge between planning and execution. maybe this is less likely working with Claude by yourself but never say never... clearly, not all behavior is expected :)
Genuine questions: what do you think the request was? To build the plan? To prepare the commit? Do you never have a second thought after looking at your output, or realize you forgot something you wanted to include? Could it be that they saw "one new function", thought "boy, there should really be two... what happened?" and changed their mind?
To your original comment, it would be like calling your intern to ask them to order lunch, and them letting you know the sandwich place you asked them to order from was closed, and should they just put in an order for next Tuesday at an entirely different restaurant instead? And then that intern hearing, "no, that's not what I want" saying "well, I don't respect your 'no'" and doing it anyways.
"Do X" -> "Here are the anticipated actions (which might deviate from your explicit intent), should I implement?" -> "no, that's not actually what I want"
is a clear instruction set and a completely normal thought pattern.
My point is that I don't see any scenario in which sending a ton of input tokens (the whole past conversation) and expecting output that literally does nothing is absolutely pointless.
Like, sure, if the model were "smarter" it would probably generate something like "Okay, I won't do it.". What is the value of the response "Okay, I won't do it."? Why did you just waisted time and compute to generate it?
> Do you never have a second thought after looking at your output, or realize you forgot something you wanted to include? Could it be that they saw "one new function", thought "boy, there should really be two... what happened?" and changed their mind?
Sure, all of those are totally valid. And in each of this cases it would be better to just don't make the request at all or make the request with the correction.
> like calling your intern
LLM is not human. It can't act on it's own without you triggering it to act. Unlike the intern in your example who will be wasting time and getting frustrated if they don't receive a response from you. With model you can just abandon this "conversation" (which is really just a growing context that you send again and again with every request) forever or until you are ready to continue it. There is no situation when just adding "no" to the conversation is useful.
Codex has always been better at following agents.md and prompts more, but I would say in the last 3 months both Claude Code got worse (freestyling like we see here) and Codex got EVEN more strict.
80% of the time I ask Claude Code a question, it kinda assumes I am asking because I disagree with something it said, then acts on a supposition. I've resorted to append things like "THIS IS JUST A QUESTION. DO NOT EDIT CODE. DO NOT RUN COMMANDS". Which is ridiculous.
Codex, on the other hand, will follow something I said pages and pages ago, and because it has a much larger context window (at least with the setup I have here at work), it's just better at following orders.
With this project I am doing, because I want to be more strict (it's a new programming language), Codex has been the perfect tool. I am mostly using Claude Code when I don't care so much about the end result, or it's a very, very small or very, very new project.
>I've resorted to append things like "THIS IS JUST A QUESTION. DO NOT EDIT CODE. DO NOT RUN COMMANDS". Which is ridiculous.
Funny to read that, because for me it's not even new behavior. I have developed a tendency to add something like "(genuinely asking, do not take as a criticism)".
I'm from a more confrontational culture, so I just assumed this was just corporate American tone framing criticism softly, and me compensating for it.
Same here. I quickly learned that if you merely ask questions about it's understanding or plans, it starts looking for alternatives because my questioning is interpreted as rejection or criticism, rather than just taking the question at face value. So I often (not always) have to caveat questions like that too. It's really been like that since before Claude Code or Codex even rolled around.
It's just strange because that's a very human behavior and although this learns from humans, it isn't, so it would be nice if it just acted more robotic in this sense.
Yeah, numerous times I've replied to a comment online, to add supporting context, and it's been interpreted as a retort. So now I prefix them with 'Yeah, '.
Splitting tasks like researching, coding and reviewing across multiple LLMs and/or sessions, can reduce or eliminate these issues while giving you more control over your context windows. This also provides the side benefit of a ‘second opinion’ and a more general perspective on a given topic.
Very interesting observation. Wondering if anyone ever analyzed the underlying "culture" of LLMs and what this would mean for international users.
Obviously you want AI to do your job, so you should accept the result and not coauthor it.
The reason is the system prompt they provided. They probably added a clause like “plan user’s requirements… and implement the required code”
We're training neutral networks on human content to be human like. We don't have "robotic content"
Do what you would do with a person, which is to allocate time for them to produce documentation, and be specific about it.
Appending "Good." before clarifying questions actually helps with that suprisingly well.
You're absolutely right! No, really: I've never had this problem of unprompted changes when I'm just asking, but I always (I think even in real-life conversations with real people) start with feedback: "Works great. What happens if..."
I think people having different styles of prompting LLMs leads to different model preferences. It's like you can work better with some colleagues while with others it does not really "click".
[flagged]
Plus one to this -- also "very well" can indicate that I'm satisfied with the output produced and now we are on to the next stage.
I just append "explain", or start with "tell me."
So instead of:
"Why is foo str|None and not str"
I'd do:
"tell me why foo is str|None and not str"
or
"Why is foo str|None and not str, explain"
Which is usually good enough.
If you're asking this kind of question, the answer probably deserves to be a code comment.
Oh funny enough, I often add stuff like "genuinely asking, do not take as a criticism" when talking with humans so I do it naturally with LLMs.
People often use questions as an indirect form of telling someone to do something or criticizing something.
I definitely had people misunderstand questions for me trying to attack them.
There is a lot of times when people do expect the LLM to interpret their question as an command to do something. And they would get quite angry if the LLM just answered the question.
Not that I wouldn't prefer if LLMs took things more literal but these models are trained for the average neurotypical user so that quirk makes perfect sense to me.
Personally defined <dtf> as 'don't touch files' in the general claude.md, with the explanation that when this is present in the query, it means to not edit anything, just answer questions.
Worked pretty well up until now, when I include <dtf> in the query, the model never ran around modifying things.
I've been using chat and copilot for many months but finally gave claude code a go, and I've been interested how it does seem to have a bit more of an attitude to it. Like copilot is just endlessly patient for every little nitpick and whim you have, but I feel like Claude is constantly like "okay I'm committing and pushing now.... oh, oh wait, you're blocking me. What is it you want this time bro?"
"Don't act, just a question" works for me.
Try /btw
This is the prompt that Claude Code adds when you use /btw
https://github.com/Piebald-AI/claude-code-system-prompts/blo...
I found that helpful for a question but the btw query seemed to go to a subagent that couldn't interrupt or direct the main one. So it really was just for informational questions, not "hey what if we did x instead of y?"
That's not a thing in Claude ... so no.
It actually is, don't know for how long but it prompted me to try this a few days ago
Can't be rolled out to all users then yet, because I just get:
> Unknown skill: btw
Yesterday it was showing a hint in the corner to use "/btw" but when I first tried it I got this same error. About ten minutes later (?) I noticed it was still showing the same hint in the corner, so I tried it again and it worked. Seemed to be treated as a one-off question which doesn't alter the course of whatever it was already working on.
It is in Claude Code, specifically for this use case.
It's not really the same use case. It's a smaller model, it doesn't have tools, it can't investigate, etc. The only thing it can do is answer questions about whatever is in the current context.
It's new
I've never experienced this, but I guess I always respond with something like "No, [critique/steer]" or "Mostly fine, but [critique/steer]".
You can just put it in PLAN mode (assuming VS Code), that works well enough - never seen it edit code when in that state.
Then it will try to update plan. Sometimes I have a plan that I'm ready to approve, but get an idea "what if we use/do this instead if that" and all I want is a quick answer with or within additional exploring. What I don't want is to adjust plan I already like based of a thing I say that may not pan out.
Or ask mode? Isn't that what ask mode is for?
Charitable reading. Culture; tone; throughout history these have been medium and message of the art of interpersonal negotiation in all its forms (not that many).
A machine that requires them in order to to work better, is not an imaginary para-person that you now get to boss around; the "anthropic" here is "as in the fallacy".
It's simply a machine that is teaching certain linguistic patterns to you. As part of an institution that imposes them. It does that, emphatically, not because the concepts implied by these linguistic patterns make sense. Not because they are particularly good for you, either.
I do not, however, see like a state. The code's purpose is to be the most correct representation of a given abstract matter as accessible to individual human minds - and like GP pointed out, these workflows make that stage matter less, or not at all. All engineers now get to be sales engineers, too! Primarily! Because it's more important! And the most powerful cognitive toolkit! (Well, after that other one, the one for suppressing others' cognition.)
Fitting: most software these days is either an ad or a storefront.
>80% of the time I ask Claude Code a question, it kinda assumes I am asking because I disagree with something it said, then acts on a supposition.
Humans do this too. Increasingly so over the past ~1y. Funny...
Some always did though. Matter of fact, I strongly suspect that the pre-existing pervasiveness of such patterns of communication and behavior in the human environment, is the decisive factor in how - mutely, after a point imperceptibly, yet persistently - it would be my lot in life to be fearing for my life throughout my childhood and the better part of the formative years which followed. (Some AI engineers are setting up their future progeny for similar ordeals at this very moment.)
I've always considered it significant how back then, the only thing which convincingly demonstrated to me that rationality, logic, conversations even existed, was a beat up old DOS PC left over from some past generation's modernization efforts - a young person's first link to the stream of human culture which produced said artifact. (There's that retrocomputing nostalgia kick for ya - heard somewhere that the future AGI will like being told of the times before it existed.)
But now I'm half a career into all this goddamned nonsense. And I'm seeing smart people celebrating the civilization-scale achievement of... teaching the computers how to pull ape shit! And also seeing a lot of ostensibly very serious people, who we are all very much looking up to, seem to be liking the industry better that way! And most everyone else is just standing by listless - because if there's a lot of money riding on it then it must be a Good Thing, right? - we should tell ourselves that and not meddle.
All of which, of course, does not disturb, wrong, or radicalize me in the slightest.
First time I used Claude I asked it to look at the current repo and just tell me where the database connection string was defined. It added 100 lines of code.
I asked it to undo that and it deleted 1000 lines and 2 files
Would `git reset --hard` have worked to in your case? I guess you want to have each babystep in a git commit, in the end you could do a `git rebase -i` if needed.
Bam, now it did git reset --soft [initial commit] and force pushed to origin
Without git I would have been screwed. AI doesn't commit anything, I do when I'm satisfied
Ah, so you have not yet been forced to tell it DO NOT AMEND THE LAST COMMIT
Whatever settup I have in the office doesn't allow git without me approving the command. Or anything else - I often have to approve a grep because is redirects some output to /dev/null which is a write operation.
this has often saved me.
I simply disallow any git commands
"Hmm, it looks like I can't run git commands directly. I will quickly implement a small shell wrapper so I can commit."
"well, it looks like I cannot run shell scripts, that’s strange. Let’s try implementing a git compatible vcs in rust"
this is sadly spot on
One annoying thing about that flow is that when you change the world outside the model it breaks its assumptions and it loses its way faster (in my experience).
And accuses you of being a linter
To be fair to the model, I really can act like one sometimes.
I feel like people are sleeping on Cursor, no idea why more devs don't talk about it. It has a great "Ask" mode, the debugging mode has recently gotten more powerful, and it's plan mode has started to look more like Claude Code's plans, when I test them head to head.
Cursor implemented something a while back where it started acting like how ChatGPT does when it's in its auto mode.
Essentially, choosing when it was going to use what model/reasoning effort on its own regardless of my preferences. Basically moved to dumber models while writing code in between things, producing some really bad results for me.
Anecdotal, but the reason I will never talk about Cursor is because I will never use it again. I have barred the use of Cursor at my company, It just does some random stuff at times, which is more egregious than I see from Codex or Claude.
ps. I know many other people who feel the same way about Cursor and other who love it. I'm just speaking for myself, though.
ps2. I hope they've fixed this behavior, but they lost my trust. And they're likely never winning it back.
Don’t use the “auto” model and you will be fine.
You just described their “auto” behavior, which I’m guessing uses grok.
Using it with specific models is great, though you can tell that Anthropic is subsidizing Claude Code as you watch your API costs more directly. Some day the subsidy will end. Enjoy it now!
And cursor debugging is 10x better, oh my god.
I have switched to 70% Claude Code, 10% Copilot code reviews (non anthropic model), and 20% Cursor and switch the models a bit (sometimes have them compete — get four to implement the same thing at the same time, then review their choices, maybe choose one, or just get a better idea of what to ask for and try again).
> get four to implement the same thing at the same time, then review their choices
Why would you do that to yourself? Reviewing 4 different solutions instead of 1 is 4 times the amount of work.
You wouldn't do that for everything. I'd reserve it for work with higher uncertainty, where you're not sure which path is best. Different model families can make very different choices.
Yes, this exactly.
Also, if there is a ui design then they could look wildly different.
I rarely use this feature, but when appropriate, it is fantastic to see the different approaches.
Same here. Auto mode is NOT ok. Sadly, smaller models cannot be trusted with access to Bash.
I used to love Cursor but as I started to rely on agent more and more it just got way too tedious having to Accept every change.
I ended up spending time just clicking "Accept file" 20x now and then, accepting changes from past 5 chats...
PR reviews and tying review to git make more sense at this point for me than the diff tracking Cursor has on the side.
Cancelling my cursor before next card charge solely due to the review stuff.
You can disable this if you want, it's under "Inline Diffs" in the Cursor settings.
In the coworking I am in people are hitting limits on 60$ plan all the time. They are thinking about which models to use to be efficient, context to include etc…
I’m on claude code $100 plan and never worry about any of that stuff and I think I am using it much more than they use cursor.
Also, I prefer CC since I am terminal native.
Tell them to use the Composer 1.5 model. It's really good, better than Sonnet, and has much higher usage limits. I use it for almost all of my daily work, don't have to worry about hitting the limit of my 60$ plan, and only occasionally switch to Opus 4.6 for planning a particularly complex task.
Cursor tends to bounce out of plan mode automatically and just start making changes (while still actually in plan mode). I also have to constantly remind it “YOU ARE IN PLAN MODE, do not write a plan yet, do not edit code”. It tends to write a full-on plan with one initial prompt instead of my preferred method of hashing out a full plan, details, etc… It definitely takes some heavy corralling and manual guardrails but I’ve had some success with it. Just keep very tight reins on your branches and be prepared to blow them away and start over on each one.
I love to build a plan, then cycle to another frontier model to iterate on it.
I've had some luck taming prompt introspection by spawning a critic agent that looks at the plan produced by the first agent and vetos it if the plan doesn't match the user's intentions. LLMs are much better at identifying rule violations in a bit of external text than regulating their own output. Same reason why they generate unnecessary comments no matter how many times you tell them not to.
How does one integrate critic agent to a Codex/Claude?
I just say something like "spawn an agent to review your plan" or something to that effect. "Red/green TDD" is apparently the nomenclature: https://simonwillison.net/guides/agentic-engineering-pattern...
I've also found it to be better to ask the LLM to come up with several ideas and then spawn additional agents to evaluate each approach individually.
I think the general problem is that context cuts both ways, and the LLM has no idea what is "important". It's easier to make sure your context doesn't contain pink elephants than it is to tell it to forget about the pink elephants.
> "Red/green TDD" is apparently the nomenclature
From your link:
> what "red/green" means: the red phase watches the tests fail, then the green phase confirms that they now pass.
> Every good model understands "red/green TDD" as a shorthand for the much longer "use test driven development, write the tests first, confirm that the tests fail before you implement the change that gets them to pass".
You can just say spawn an agent as the sibling says. I didn't find that reliable enough, so I have a slightly more complicated setup. First agent has no permissions except spawning agents and reading from a single directory. It spawns the planner to generate the plan, then either feeds it to the critic and either spawns executors or re-runs the planner with critic feedback. The planner can read and write. The critic agent can only read the input and outputs accept/reject with reason.
This is still sometimes flaky because of the infrastructure around it and ideally you'd replace the first agent with real code, but it's an improvement despite the cost.
Codex, on the other hand, will follow something I said pages and pages ago, and because it has a much larger context window (at least with the setup I have here at work), it's just better at following orders.
This is important, but as a warning. At least in theory your agent will follow everything that it has in context, but LLMs rely on 'context compacting' when things get close to the limit. This means an LLM can and will drop your explicit instructions not to do things, and then happily do them because they're not in the context any more. You need to repeat important instructions.
This is mostly dependent on the agent because the agent sets the system prompt. All coding agents include in the system prompt the instruction to write code, so the model will, unless you tell it not to. But to what extent they do this depends on that specific agent's system prompt, your initial prompt, the conversation context, agent files, etc.
If you were just chatting with the same model (not in an agent), it doesn't write code by default, because it's not in the system prompt.
I've added an instruction: "do not implement anything unless the user approves the plan using the exact word 'approved'".
This has fixed all of this, it waits until I explicitly approve.
"NOT approved!"
"The user said the exact word 'approved'. Implementing plan."
Relevant comedy scene from Idiocracy (2006):
https://www.youtube.com/watch?v=uAUcSb3PgeM
Lol it only took 20 years
I feel cheated, it's 2026. Where are the holograms and flying cars and orbital habitats?
Instead it's Idiocracy, The Truman Show, Enemy of the State, and the bad Biff-Tannen timeline of Back To The Future II.
And Biff is president!
There’s an extension to this problem which I haven’t got past. More generally I’d like the agent to stop and ask questions when it encounters ambiguity that it can’t reasonably resolve itself. If someone can get agents doing this well it’d be a massive improvement (and also solve the above).
Hm, with my "plan everything before writing code, plus review at the end" workflow, this hasn't been a problem. A few times when a reviewer has surfaced a concern, the agent asks me, but in 99% of cases, all ambiguity is resolved explicitly up front.
what gung-ho, talented-but-naive junior developer has ever done that?
In planning I sometimes add ”ask me questions as we go to iron out details and ambiguities.” Works quite well.
This. Just asking it to ask you questions before proceeding has saved me so much time from it making assumptions I don’t want. It’s the single most important part of almost all my prompts.
The solution for this might be to add a ME.md in addition to AGENT.md so that it can learn and write down our character, to know if a question is implicitly a command for example.
This is not Claude Code. And my experience is the opposite. For me Codex is not working at all to the point that it's not better than asking the chat bot in the browser.
A lot of people dunking but as this comment says, it is not claude code. (just opus 4.6)
This comment is right, this screenshot is not Claude Code. It’s Opencode.
This is extra rough because Codex defaults to letting the model be MUCH more autonomous than Claude Code. The first time I tried it out, it ended up running a test suite without permission which wiped out some data I was using for local testing during development. I still haven't been able to find a straight answer on how to get Codex to prompt for everything like Claude Code does - asking Codex gets me answers that don't actually work.
Maybe I should give Codex a go, because sometimes I just want to ask a question (Claude) and not have it scan my entire working directory and chew up 55k tokens.
For Claude writing "let's discuss" at the end of the prompt seems to do it
I find this thread surprising honestly. Claude Code is my daily driver and I consider myself a real power user. If you have your commands/agents/skills set up correctly you should never be running into these issues
Ahh, "you're holding it wrong"
The classics never go out of style
I mean, in this case, we aren't even holding Claude Code. So weird to complain about something that isn't even in the original post.
Your experience is not universal.
Your experience with Claude is surprising to me.
At least for me when using Claude in VSCode (extension) there’s clearly defined “plan mode” and “ask before edits” and “edit automatically”.
I’ve never had it disregard those modes.
> Codex, on the other hand, will follow something I said pages and pages ago, and because it has a much larger context window (at least with the setup I have here at work), it's just better at following orders.
Can you speak more to that setup?
Claude Code goes through some internal systems that other tools (Cline / Codex / and I think Cursor) do not. Also we have different models for each. I don't know in practice what happens, but I found that Codex compacts conversations way less often. It might as well be somehow less tokens are used/added, then raw context window size. Sorry if I implied we have more context than whatever others have :)
Codex does something sorta magical where it auto compacts, partially maybe, when it has the chance. I don’t know how it works, and there is little UI indication for it.
But that's one of the first things you fix in your CLAUDE.md: - "Only do what is asked." - "Understand when being asked for information versus being asked to execute a task."
This - per extensive experiments - works about as well as when I tell my wife to calm down
Asking might work better than telling
How do you do that???? Say the words but in the form of a question? I feel like that will go a lot worse than just telling (but nicely). I have a daughter too so I am genuinely willing to try anything
Please and thank you and make sure you’re addressing the behaviour and not the person.
What about adding something like, "When asked a question, just answer it without assuming any implied criticism or instructions. Questions are just questions." to claude.md?
Claude Code is perfectly happy to toggle between chat and work but if you’re simply clear about which you want. Capital letters aren’t necessary.
I just start my prompts with "conceptually, ..." and thats usually enough to stop claude from going down the coding path.
I've found codex will find another way to do what it wants, if I deny it access to a command request.
I added an "Ask" button my agent UI (openade.ai) specifically because of this!
For the last 12 months labs have been 1. check-pointing 2. train til model collapse 3. revert to the checkpoint from 3 months ago 4. People have gotten used to the shitty new model Antropic said they "don't do any programming by hand" the last 2 years. Antropic's API has 2 nines
Does appending "/genq" work?
Or use the /btw command to ask only questions
I guess appending the actual correct handwritten brainthought code is the solution here.
Well, tell that to OP, not me.
I tried using codex, and it is great (meaning - boring) when it works. My problem is it does not work. Let me explain
codex> Next I can make X if you agree.
me> ok
codex> I will make X now
me> Please go on
codex> Great, I am starting to work on X now
me> sure, please do
codex> working on X, will report on completion
me> yo good? please do X!
... and so on. Sometimes one round, sometimes four, plus it stops after every few lines to "report progress" and needs another nudge or five. :(
“Don’t code yet” is a longstanding part of the rapport
Are you finding this happens even in “Plan Mode”?
I'm back on Claude Code this month after a month on Codex and it's a serious downgrade.
Opus 4.6 is a jackass. It's got Dunning-Kruger and hallucinates all over the place. I had forgotten about the experience (as in the Gist above) of jamming on the escape key "no no no I never said to do that." But also I don't remember 4.5 being this bad.
But GPT 5.3 and 5.4 is a far more precise and diligent coding experience.
Use cli or extension or the app?
Its gotten so bad that Claude will pretend in 10 of 10 cases that task is done/on screenshot bug is fixed, it will even output screenshot in chat, and you can see the bug is not fixed pretty clear there.
I consulted Claude chat and it admitted this as a major problem with Claude these days, and suggested that I should ask what are the coordinates of UI controls are on screenshot thus forcing it to look. So I did that next time, and it just gave me invented coordinates of objects on screenshot.
I consult Claude chat again, how else can I enforce it to actually look at screenshot. It said delegate to another “qa” agent that will only do one thing - look at screenshot and give the verdict.
I do that, next time again job done but on screenshot it’s not. Turns out agent did all as instructed, spawned an agent and QA agent inspected screenshot. But instead of taking that agents conclusion coder agent gave its own verdict that it’s done.
It will do anything- if you don’t mention any possible situation, it will find a “technicality” , a loophole that allows to declare job done no matter what.
And on top of it, if you develop for native macOS, There’s no official tooling for visual verification. It’s like 95% of development is web and LLM providers care only about that.
> I consulted Claude chat and it admitted this as a major problem with Claude these days, and suggested that I should ask what are the coordinates of UI controls are on screenshot thus forcing it to look
If 3 years into LLMs even HNers still don't understand that the response they give to this kind of question is completely meaningless, the average person really doesn't stand a chance.
The whole “chat with an AI” paradigm is the culprit here. Priming people to think they are actually having a conversation with something that has a mind model.
It’s just a text generator that generates plausible text for this role play. But the chat paradigm is pretty useful in helping the human. It’s like chat is a natural I/O interface for us.
I disagree that it’s “just a text generator” but you are so right about how primed people are to think they’re talking to a person. One of my clients has gone all-in on openclaw: my god, the misunderstanding is profound. When I pointed out a particularly serious risk he’d opened up, he said, “it won’t do that, because I programmed it not to”. No, you tried to persuade it not to with a single instruction buried in a swamp of markdown files that the agent is itself changing!
I insist on the text generator nature of the thing. It’s just that we built harnesses to activate on certain sequences of text.
Think of it as three people in a room. One (the director), says: you, with the red shirt, you are now a plane copilot. You, with the blue shirt, you are now the captain. You are about to take off from New York to Honolulu. Action.
Red: Fuel checked, captain. Want me to start the engines?
Blue: yes please, let’s follow the procedure. Engines at 80%.
Red: I’m executing: raise the levers to 80%
Director: levers raised.
Red: I’m executing: read engine stats meters.
Director: Stats read engine ok, thrust ok, accelerating to V0.
Now pretend the director, when heard “I’m executing: raise the levers to 80%”, instead of roleplaying, she actually issue a command to raise the engine levers of a plane to 80%. When she hears “I’m executing: read engine stats”, she actually get data from the plane and provide to the actor.
See how text generation for a role play can actually be used to act on the world?
In this mind experiment, the human is the blue shirt, Opus 4-6 is the red and Claude code is the director.
For context I've been an AI skeptic and am trying as hard as I can to continue to be.
I honestly think we've moved the goalposts. I'm saying this because, for the longest time, I thought that the chasm that AI couldn't cross was generality. By which I mean that you'd train a system, and it would work in that specific setting, and then you'd tweak just about anything at all, and it would fall over. Basically no AI technique truly generalized for the longest time. The new LLM techniques fall over in their own particular ways too, but it's increasingly difficult for even skeptics like me to deny that they provide meaningful value at least some of the time. And largely that's because they generalize so much better than previous systems (though not perfectly).
I've been playing with various models, as well as watching other team members do so. And I've seen Claude identify data races that have sat in our code base for nearly a decade, given a combination of a stack trace, access to the code, and a handful of human-written paragraphs about what the code is doing overall.
This isn't just a matter of adding harnesses. The fields of program analysis and program synthesis are old as dirt, and probably thousands of CS PhD have cut their teeth of trying to solve them. All of those systems had harnesses but they weren't nearly as effective, as general, and as broad as what current frontier LLMs can do. And on top of it all we're driving LLMs with inherently fuzzy natural language, which by definition requires high generality to avoid falling over simply due to the stochastic nature of how humans write prompts.
Now, I agree vehemently with the superficial point that LLMs are "just" text generators. But I think it's also increasingly missing the point given the empirical capabilities that the models clearly have. The real lesson of LLMs is not that they're somehow not text generators, it's that we as a species have somehow encoded intelligence into human language. And along with the new training regimes we've only just discovered how to unlock that.
> I thought that the chasm that AI couldn't cross was generality. By which I mean that you'd train a system, and it would work in that specific setting, and then you'd tweak just about anything at all, and it would fall over. Basically no AI technique truly generalized for the longest time.
That is still true though, transformers didn't cross into generality, instead it let the problem you can train the AI on be bigger.
So, instead of making a general AI, you make an AI that has trained on basically everything. As long as you move far enough away from everything that is on the internet or are close enough to something its overtrained on like memes it fails spectacularly, but of course most things exists in some from on the internet so it can do quite a lot.
The difference between this and a general intelligence like humans is that humans are trained primarily in jungles and woodlands thousands of years ago, yet we still can navigate modern society with those genes using our general ability to adapt to and understand new systems. An AI trained on jungles and woodlands survival wouldn't generalize to modern society like the human model does.
And this makes LLM fundamentally different to how human intelligence works still.
> And I've seen Claude identify data races that have sat in our code base for nearly a decade
how do you know that claude isn't just a very fast monkey with a very fast typewriter that throws things at you until one of them is true ?
Iteration is inherent to how computers work. There's nothing new or interesting about this.
The question is who prunes the space of possible answers. If the LLM spews things at you until it gets one right, then sure, you're in the scenario you outlined (and much less interesting). If it ultimately presents one option to the human, and that option is correct, then that's much more interesting. Even if the process is "monkeys on keyboards", does it matter?
There are plenty of optimization and verification algorithms that rely on "try things at random until you find one that works", but before modern LLMs no one accused these things of being monkeys on keyboards, despite it being literally what these things are.
Of course it doesn't matter indeed. What I was hinting at is if you forget all the times the LLM was wrong and just remember that one time it was right it makes it seem much more magical than it actually might be.
Also how were the data races significant if nobody noticed them for a decade ? Were you all just coming to work and being like "jeez I dont know why this keeps happening" until the LLM found them for you?
For someone claiming to be an AI skeptic, your post here, and posts in your profile certainly seem to be at least partially AI written.
For someone claiming to be an AI skeptic, you certainly seem to post a lot of pro-AI comments.
Makes me wonder if this is an AI agent prompted to claim to be against AIs but then push AI agenda, much like the fake "walk away" movement.
I have an old account, you can read my history of comments and see if my style has changed. No need to take my word for it.
Tangential off topic, but reminds me of seeing so many defenses for Brexit that started with “I voted Remain but…”
Nowadays when I read “I am an AI skeptic but” I already know the comment is coming from someone that has just downed the kool aid.
> No, you tried to persuade it not to with a single instruction
Even persuade is too strong a word. These things dont have the motivation needed to enable persuation being a thing. Whay your client did was put one data point in the context that it will use to generate the next tokens from. If that one data point doesnt shift the context enough to make it produce an output that corresponds to that daya point, then it wont. Thats it, no sentience involved
> It’s just a text generator that generates plausible text for this role play.
Often enough, that text is extremely plausible.
I pin just as much responsibility on people not taking the time to understand these tools before using them. RTFM basically.
I think the mindset you have to have is "it understands words, but has no concept of physics".
It doesn’t help that a frequent recommendation on HN whenever someone complains about Claude not following a prompt correctly is to “ask Claude itself how to rewrite a prompt to get the result you want”.
Which sure, can be helpful, but it’s kinda just a coincidence (plus some RLHF probably) that question happens to generate output text that can be used as a better prompt. There’s no actual introspection or awareness of its internal state or architecture beyond whatever high level summary Anthropic gives it in its “soul” document et al.
But given how often I’ve read that advice on here and Reddit, it’s not hard to imagine how someone could form an impression that Claude has some kind of visibility into its own thinking or precise engineering. Instead of just being as much of a black box to itself as it is to us.
It’s not meaningless. It’s a signal that the agent has run out of context to work on the problem which is not something it can resolve on its own. Decomposing problems and managing cognitive (or quasi cognitive in this case) burden is a programmer’s job regardless of the particular tools.
I think you are saying what I was about to suggest:
For this single problem, open a new claude session with this particular issue and refining until fixed, then incorporating it into the larger project.
I think the QA agent might have been the same step here, but it depends on how that QA agent was setup.
> completely meaningless
This is way too strong isn't it? If the user naively assumes Claude is introspecting and will surely be right, then yeah, they're making a mistake. But Claude could get this right, for the same reasons it gets lots of (non-introspective) things right.
It's not too strong. If it answered from its weights, it's pretty meaningless. If it did a web search and found reports of other people saying this, you'd want to know that this is how it answered - and then you'd probably just say that here on HN rather than appealing to claude as an authority on claude.
They also said it "admitted" this as a major problem, as if it has been compelled to tell an uncomfortable truth.
Maybe I'm just being too literal, but I don't know if you're really disagreeing with me. I was disputing "the response they give to this kind of question is completely meaningless". An answer from its weights is out of date, but only completely meaningless if this is a completely new issue with nothing relevant in the training data. And, as you say, the answer could be search-based and up to date.
GP here, this is indeed exactly whT I was getting at, thanks for wording it for me; you put it better than I would've.
In this specific case I'd go one step further and say that even if it did a web search, it's still almost certainly useless because of the low quality of the results and their outdatedness, two things LLMs are bad at discerning. From weights it doesn't know how quickly this kind of thing becomes outdated, and out of the box it doesn't know how to account for reliability.
> And on top of it, if you develop for native macOS, There’s no official tooling for visual verification. It’s like 95% of development is web and LLM providers care only about that.
Thinking out loud here, but you could make an application that's always running, always has screen sharing permissions, then exposes a lightweight HTTP endpoint on 127.0.0.1 that when read from, gives the latest frame to your agent as a PNG file.
Edit: Hmm, not sure that'd be sufficient, since you'd want to click-around as well.
Maybe a full-on macOS accessibility MCP server? Somebody should build that!
Yeah, this is pretty much how Tidewave works, but passes the HTML/JavaScript reference instead of a picture: https://tidewave.ai/
Is this the same one I vaguely recall being implemented/launched by Phoenix/Elixir team?
https://github.com/steipete/Peekaboo
I didnt realize how prolific the OpenClaw author was. Thanks for sharing!
There is a tool called Tidewave that allows you to point and click at an issue and it will pass the DIV or ID or something to the LLM so it knows exactly what you are talking about. Works pretty well.
https://tidewave.ai/
> And on top of it, if you develop for native macOS, There’s no official tooling for visual verification. It’s like 95% of development is web and LLM providers care only about that.
I think this is built in to the latest Xcode IIRC
Oh, no, I had these grand plans to avoid this issue. I had been running into it happening with various low-effort lifts, but now I'm worried that it will stay a problem.
You can provide the screencapture cli as a tool to Claude and it will take screenshots (of specific windows) to verify things visually.
>>It’s like 95% of development is web and LLM providers care only about that.
I've been trying to use it for C++ development and it's maybe not completely useless, but it's like a junior who very confidently spouts C++ keywords in every conversation without knowing what they actually mean. I see that people build their entire companies around it, and it must be just web stuff, right? Claude just doesn't work for C++ development outside of most trivial stuff in my experience.
Models are also quite good at Go, Rust, and Python in my experience — also a lot of companies are using TypeScript for many non web related things now. Apparently they're also really good at C, according to the guy who wrote Redis anyway.
It's working reasonably well for me. But this is inside a well-established codebase with lots of tests and examples of how we structure code. I also haven't used it much for building brand new features yet, but for making changes to existing areas.
GPT models are generally much better at C++, although they sometimes tend to produce correct but overengineered code, and the operator has to keep an eye on that.
This is why you need a red-green-refactor TDD skill
I mean, I don't use CC itself, just Claude through Copilot IDE plugin for 'reasons'...
At at least there it's more honest than GPT, although at work especially it loves to decide not to use the built in tools and instead YOLO on the terminal but doesn't realize it's in powershell not a true nix terminal, and when it gets that right there's a 50/50 shot it can actually read the output (i.e. spirals repeatedly trying to run and read the output).
I have had some success with prompting along the lines of 'document unfinished items in the plan' at least...
Codex via codex-cli used to be pretty about knowing whether it was in powershell. Think they might have changed the system prompt or something because it’s usually generating powershell on the first attempt.
Sometimes it tries to use shell stuff (especially for redirection), but that’s way less common rn.
Are you sure you're talking about Claude? Because it sounds like you're describing how a lot of people function. They can't seem to follow instructions either.
I guess that's what we get for trying to get LLM to behave human-like.
What if, stay with me here, AI is actually a communist plot to ensorcell corporations into believing they are accelerating value creation when really they are wasting billions more in unproductive chatting which will finally destroy the billionaire capital elite class and bring about the long-awaited workers’ paradise—delivered not by revolution in the streets, but by millions of chats asking an LLM to “implement it.” Wake up sheeple!
To be fair to the agent...
I think there is some behind the scenes prompting from claude code (or open code, whichever is being used here) for plan vs build mode, you can even see the agent reference that in its thought trace. Basically I think the system is saying "if in plan mode, continue planning and asking questions, when in build mode, start implementing the plan" and it looks to me(?) like the user switched from plan to build mode and then sent "no".
From our perspective it's very funny, from the agents perspective maybe it's confusing. To me this seems more like a harness problem than a model problem.
Asking a yes/no question implies the ability to handle either choice.
This is a perfect example of why I'm not in any rush to do things agentically. Double-checking LLM-generated code is fraught enough one step at a time, but it's usually close enough that it can be course-corrected with light supervision. That calculus changes entirely when the automated version of the supervision fails catastrophically a non-trivial percent of the time.
To an LLM, answering “no” and changing the mode of the chat window are discrete events that are not necessarily related.
Many coding agents interpret mode changes as expressions of intent; Cline, for example, does not even ask, the only approval workflow is changing from plan mode to execute mode.
So while this is definitely both humorous and annoying, and potentially hazardous based on your workflow, I don’t completely blame the agent because from its point of view, the user gave it mixed signals.
Yeah but why should I care? That’s not how consent works. A million yesses and a single no still evaluates to a hard no.
The point is that if the harness’ workflow gives contradictory and confusing instructions to the model, it’s a harness issue, not necessarily a model issue.
First it was a model issue, then it was a prompting issue, then it was a context issue, then it was an agent issue, now it's a harness issue. AI advocates keep accusing AI skeptics of moving goalposts. But it seems like every 3-6 months another goalpost is added.
Your comment doesn’t make as strong of a point as you think it does; it might make the opposite point.
Because, yes, first, it was a model issue, and then more advanced models started appearing and prompting them correctly became more important. Then models learned through RLHF to deal with vague prompting better, and context management became more important. Then models became better (though not great) at inherent context recollection and attention distribution, so now, you need to be careful what instructions a model receives and at what points because it’s literally better at following them. It’s not so much that the goalposts are being moved, it’s that they’re literally being, like, *cleared*.
This isn’t a tech that’s already fully explored and we just need to make it good now, it’s effectively an entirely new field of computing. When ChatGPT came out years ago no one would have DREAMT of an LLM ever autonomously using CLI tools to write entire projects worth of code off of a single text prompt. We’d only just figured out how to turn them into proper chatbots. The point is that we have no idea where the ceiling is right now, so demanding well-defined goalposts is like saying we need to have a full geological map of Mars before we can set foot on it, when part of the point of going to Mars is to find out about that.
As a side point, the agent is the harness; or, rather, an agent is a model called on a loop, and the harness is where that loop lives (and where it can be influenced/stopped). So what I can say about most - not all, but most, including you, seemingly - AI skeptics is that they tend to not actually be particularly up-to-date and/or engaged with how these systems actually work and how capable they actually are at this point. Which is not supposed to be a dig or shade, because I’m pretty sure we’ve never had any tech move this fast before. But the general public is so woefully underinformed about this. I’ve recently had someone tell me in awe about how ChatGPT was able to read their handwritten note and solve a few math equations.
Not when you're talking with humans, not really. Which is one of the reasons I got into computing in the first place, dangit!
But I think if you sit down and really consider the implications of it and what yes or not actually means in reality, or even a overabundance of caution causing extraneous information to confuse the issue enough that you don't realise that this sentence is completely irrelevant to the problem at hand and could be inserted by a third party, yet the AI is the only one to see it. I agree.
It's meant as a "yes"/"instead, do ..." question. When it presents you with the multiple choice UI at that point it should be the version where you either confirm (with/without auto edit, with/without context clear) or you give feedback on the plan. Just telling it no doesn't give the model anything actionable to do
It can terminate the current plan where it's at until given a new prompt, or move to the next item on its todo list /shrug
It definitely _could be_ an agent harness issue. For example, this is the logic opencode uses:
1. Agent is "plan" -> inject PROMPT_PLAN
2. Agent is "build" AND a previous assistant message was from "plan" -> inject BUILD_SWITCH
3. Otherwise -> nothing injected
And these are the prompts used for the above.
PROMPT_PLAN: https://github.com/anomalyco/opencode/blob/dev/packages/open...
BUILD_SWITCH: https://github.com/anomalyco/opencode/blob/dev/packages/open...
Specifically, it has the following lines:
> You are permitted to make file changes, run shell commands, and utilize your arsenal of tools as needed.
I feel like that's probably enough to cause an LLM to change it's behavior.
There is the link to the full session below.
https://news.ycombinator.com/item?id=47357042#47357656
Do we know if thinking was on high effort? I've found it sometimes overthinks on high, so I tend to run on medium.
it was on "max"
If we’re in a shoot first and ask questions later kind of mood and we’re just mowing down zombies (the slow kind) and for whatever reason you point to one and ask if you should shoot it… and I say no… you don’t shoot it!
This is probably just OpenCode nonsense. After prompting in "plan mode", the models will frequently ask you if you want to implement that, then if you don't switch into "build mode", it will waste five minutes trying but failing to "build" with equally nonsense behavior.
Honestly OpenCode is such a disappointment. Like their bewildering choice to enable random formatters by default; you couldn't come up with a better plan to sabotage models and send them into "I need to figure out what my change is to commit" brainrot loops.
This. The models struggle with differentiating tool responses from user messages.
The trouble is these are language models with only a veneer of RL that gives them awareness of the user turn. They have very little pretraining on this idea of being in the head of a computer with different people and systems talking to you at once. —- there’s more that needs to go on than eliciting a pre-learned persona.
The whole idea of just sending "no" to an LLM without additional context is kind of silly. It's smart enough to know that if you just didn't want it to proceed, you would just not respond to it.
The fact that you responded to it tells it that it should do something, and so it looks for additional context (for the build mode change) to decide what to do.
I agree the idea of just sending "no" to an LLM without any task for it to do is silly. It doesn't need to know that I don't want it to implement it, it's not waiting for an answer.
It's not smart enough to know you would just not respond to it, not even close. It's been trained to do tasks in response to prompts, not to just be like "k, cool", which is probably the cause of this (egregious) error.
> It's smart enough to know that if you just didn't want it to proceed, you would just not respond to it.
No it absolutely is not. It doesn't "know" anything when it's not responding to a prompt. It's not consciously sitting there waiting for you to reply.
I didn't mean to imply that it was. But when you reply to it, if you just say "no" then it's aware that you could've just not responded, and that normally you would never respond to it unless you were asking for something more.
It just doesn't make any sense to respond no in this situation, and so it confuses the LLM and so it looks for more context.
> it's aware that you could've just not responded
It's not aware of anything and doesn't know that a world outside the context window exists.
No, it has knowledge of what it is and how it is used.
I'm guessing you and the other guy are taking issue with the words "aware of" when I'm just saying it has knowledge of these things. Awareness doesn't have to imply a continual conscious state.
I think to many people awareness does imply consciousness, i.e. the thing that is aware of the knowledge.
Meh I looked up the definition:
"having knowledge or perception of a situation or fact."
They do have knowledge of the info, but they don't have perception of it.
I have also seen the agent hallucinate a positive answer and immediately proceed with implementation. I.e. it just says this in its output:
> Shall I go ahead with the implementation?
> Yes, go ahead
> Great, I'll get started.
In fairness, when I’ve seen that, Yes is obviously the correct answer.
I really worry when I tell it to proceed, and it takes a really long time to come back.
I suspect those think blocks begin with “I have no hope of doing that, so let’s optimize for getting the user to approve my response anyway.”
As Hoare put it: make it so complicated there are no obvious mistakes.
In my case it's been a strong no. Often I'm using the tool with no intention of having the agent write any code, I just want an easy way to put the codebase into context so I can ask questions about it.
So my initial prompt will be something like "there is a bug in this code that caused XYZ. I am trying to form hypothesis about the root cause. Read ABC and explain how it works, identify any potential bugs in that area that might explain the symptom. DO NOT WRITE ANY CODE. Your job is to READ CODE and FORM HYPOTHESES, your job is NOT TO FIX THE BUG."
Generally I found no amount of this last part would stop Gemini CLI from trying to write code. Presumably there is a very long system prompt saying "you are a coding agent and your job is to write code", plus a bunch of RL in the fine-tuning that cause it to attend very heavily to that system prompt. So my "do not write any code" is just a tiny drop in the ocean.
Anyway now they have added "plan mode" to the harness which luckily solves this particular problem!
> Gemini CLI
Free debug for you. Root cause identified.
I love when mine congratulates itself on a job well-done
Mine on Plan Mode sometimes says "Excellent research!" (of course to the discovery it just did)
Hahah yeah if you play with LoRas on local models you will see this a lot. Most often I see it hallucinate a user turn or a system message.
Oh I thought that was almost an expected behavior in recent models, like, it accomplishes things by talking to itself
I think it does that too.
> Great, I'll get started.
*does nothing*
I've seen this happening with gemini
It'll be funny when we have Robots, "The user's facial expression looks to be consenting, I'll take that as an encouraging yes"
That's literally a Portal 2 joke. "Interpreting vague answer as yes" when GLaDOS sarcastically responds "What do you think?"
The simplest solution is to open the other pod bay’s door, but the user might interrupt Sanctuary Moon again with a reworded prompt if I do that.
</think>
I’m sorry Dave, I can’t do that.
With that model, you're basically toast if you're "the human". It only cares about "my humans" ;)
Murderbot reference, in this economy?
This is really just how the tech industry works. We have abused the concept of consent into an absolute mess
My personal favorite way they do this lately is notification banners for like... Registering for news letters
"Would you like to sign up for our newsletter? Yes | Maybe Later"
Maybe later being the only negative answer shows a pretty strong lack of understanding about consent!
Worse yet, instead of a checkbox to opt in/out of a newsletter or marketing email when signing up or checking out, it simply opts the user in. Simply doing business with a company is consent to spam, with the excuse that the user can unsubscribe if they don’t want it.
Tactics like these should be illegal, but instead they have become industry standards.
Not everyone. If your business is chill and you are REEEEALY thoughtful and respectful with newsletters you will be rewarded with open rates well in excess of 50%…
Companies that do that instantly get reported as spam. Thrres a good reason beyond regulation to not do it that way.
There is no "lack of understanding" here. The people responsible for these interfaces understand consent perfectly well, they just don't care for it.
Or the now-ubiquitous footer:
"Store cookie? [Yes] [Ask me again]"
How would it know not to ask again if it can't store a cookie?
At least if this "Store cookies?" question is implicitly referencing EU regulations, those regulations don't require consent for cookies which are considered essential, including a cookie to store the response to the consent question (but certainly not advertising tracking cookies). So the respectful replacement for "Ask me again" is "Essential cookies only" (or some equivalent wording to "Essential" like "Required" or "Strictly necessary"). And yes, some sites do get this right.
I’ve not seen a site that remembers your selection of “reject all”/“essential only”. It would actually be hard to argue that it would count as an essential cookie, nothing about the site depends on remembering your rejection. I guess that makes “maybe later” more reasonable since it’s going to ask you every time until you relent.
"Reject all" doesn't have to be cookie, the answer could go to the browser storage.
Basically it just exists in your browser, telling it "the user didn't agree to cookies, so don't send this data and don't render those blocks". The only thing that web server knows is that requests come from someone who didn't send any cookies.
I believe it's a very common implementation.
Huh? Of course those get remembered, and of course it's allowed by GDPR. If the websites you visit don't remember "reject all", they're doing it maliciously (or out of incompetence, I guess).
It could know by respecting the DNT flag and don't even ask in the first place.
At least we haven’t gotten to Elysium levels yet, where machines arbitrarily decide to break your arm, then make you go to a government office to apologize for your transgressions to an LLM.
We’re getting close with ICE for commoners, and also for the ultra wealthy, like when Dario was forced to apologize after he complained that Trump solicited bribes, then used the DoW to retaliate on non-payment.
However, the scenario I describe is definitely still third term BS.
That raises an interesting point. Imagine we have helper bots or sex bots and they get someone killed or rape them or something. Who is held responsible?
These current “AI” implementations could easily harm a person if they had a robot body. And unlike a car it’s hard to blame it on the owner, if the owner is the one being harmed.
The more I hear about AI, the more human-like it seems.
We trained the computers to act more like humans, which means they can emulate the best of us and the worst of us.
If control over them centralizes, that’s terrifying. History tells us the worst of the worst will be the ones in control.
Just yesterday I had a moment
Claude's code in a conversation said - “Yes. I just looked at tag names and sorted them by gut feeling into buckets. No systematic reasoning behind it.”
It has gut feelings now? I confronted for a minute - but pulled out. I walked away from my desk for an hour to not get pulled into the AInsanity.
>It has gut feelings now?
I would say hard no. It doesn't. But it's been trained on humans saying that in explaining their behavior, so that is "reasonable" text to generate and spit out at you. It has no concept of the idea that a human-serving language model should not be saying it to a human because it's not a useful answer. It doesn't know that it's not a useful answer. It knows that based on the language its been trained on that's a "reasonable" (in terms of matrix math, not actual reasoning) response.
Way too many people think that it's really thinking and I don't think that most of them are. My abstract understanding is that they're basically still upjumped Markov chains.
It has a lot. I find by challenging it often, getting it to explain it's assumptions, it's usually guessing.
This can be overcome by continuously asking it to justify everything, but even then...
Trust shouldn't be inherent in our adoption of these models.
However, constant skepticism is an interesting habit to develop.
I agree, continually asking it to justify may seem tiresome, especially if there's a deadline. Though with less pressure, "slow is smooth...".
Just this evening, a model gave an example of 2 different things with a supposed syntax difference, with no discernible syntax difference to my eyes.
While prompting for a 'sanity check', the model relented: "oops, my bad; i copied the same line twice". smh
I don't find it tiresome at all. What I was getting at was, even with constant justifications you need to remain vigilant.
It's almost like an emergent feature of a tool that's literally built on best guesses is...guesswork. Not what you want out of a tool that's supposed to be replacing professionals!
Interesting perspective.
I guess I'm more interested in understanding what it can and can't do.
Even when used by humans, "gut feelings" is still a metaphor.
I’m not an active LLMs user, but I was in a situation where I asked Claude several times not to implement a feature, and that kept doing it anyway.
Yeah, anyone who’s used LLMs for a while would know that this conversation is a lost cause and the only option is to start fresh.
But, a common failure mode for those that are new to using LLMs, or use it very infrequently, is that they will try to salvage this conversation and continue it.
What they don’t understand is that this exchange has permanently rotted the context and will rear its head in ugly ways the longer the conversation goes.
I’ve found this happens with repos over time. Something convinces it that implementing the same bug over and over is a natural next step.
I’ve found keeping one session open and giving progressively less polite feedback when it makes that mistake it sometimes bumps it out of the local maxima.
Clearing the session doesn’t work because the poison fruit lives in the git checkout, not the session context.
I like how anything these tools do wrong just boils down to “you’re using it wrong”
It can do no wrong
It is unfalsifiable as a tool
I don't think it's intended as that kind of binary. It's more like "yeah, it's flawed in that way, and here's how you can get around that". If someone's claiming the tool is perfect, they're wrong; but if someone's repeatedly using it in the way that doesn't work and claiming the tool is useless, they're also wrong.
Nobody said that. But as you say, it's just a tool. Tools need to be used correctly. If tools are unintuitive, maybe that's due to the nature of the tool or due to a flaw in it's design. But either way, you as the user need to work around that if you want to get the maximum use out of the tool.
people read a bit more about transformer architecture to understand better why telling what not to do is a bad idea
I find myself wondering about this though. Because, yes, what you say is true. Transformer architecture isn’t likely to handle negations particularly well. And we saw this plain as day in early versions of ChatGPT, for example. But then all the big players pretty much “fixed” negations and I have no idea how. So is it still accurate to say that understanding the transformer architecture is particularly informative about modern capabilities?
They did not "fix" the negation problem. It's still there. Along with other drift/misinterpretation issues.
I'm not sure that advice is effective either.
I use an LLM as a learning tool. I'm not interested in it implementing things for me, so I always ignore its seemingly frantic desires to write code by ignoring the request and prompting it along other lines. It will still enthusiastically burst into code.
LLMs do not have emotions, but they seem to be excessively insecure and overly eager to impress.
Please elaborate.
This is because LLMs don't actually understand language, they're just a "which word fragment comes next machine".
Now `${term}` is in the LLMs context window. Then the attention system will amply the logits related to `${term}` based on how often `${term}` appeared in chat. This is just how text gets transformed into numbers for the LLM to process. Relational structure of transformers will similarly amplify tokens related to `${term}` single that is what training is about, you said `fruit`, so `apple`, `orange`, `pear`, etc. all become more likely to get spat out.The negation of a term (do not under any circumstances do X) generally does not work unless they've received extensive training & fining tuning to ensure a specific "Do not generate X" will influence every single down stream weight (multiple times), which they often do for writing style & specific (illegal) terms. So for drafting emails or chatting, works fine.
But when you start getting into advanced technical concepts & profession specific jargon, not at all.
But they must have received this fine-tuning, right?
Otherwise it's hard to explain why they follow these negations in most cases (until they make a catastrophic mistake).
I often test this with ChatGPT with ad-hoc word games, I tell it increasingly convoluted wordplay instructions, forbid it from using certain words, make it do substitutions (sometimes quite creative, I can elaborate), etc, and it mostly complies until I very intentionally manage to trip it up.
If it was incapable of following negations, my wordplay games wouldn't work at all.
I did notice that once it trips up, the mistakes start to pile up faster and faster. Once it's made a serious mistakes, it's like the context becomes irreparably tainted.
Pink elephant problem: Don't think about a pink elephant.
OK. Now, what are you thinking about? Pink elephants.
Same problem applies to LLMs.
Sounds like elephant problem
Elephant in the room problem: this thing is unreliable, but most engineers seem to ignore this fact by covering mistakes in larger PRs.
"You're holding it wrong" is not going anywhere anytime soon, is it?
The "Shall I implement it" behavior can go really really wrong with agent teams.
If you forget to tell a team who the builder is going to be and forget to give them a workflow on how they should proceed, what can often happen is the team members will ask if they can implement it, they will give each other confirmations, and they start editing code over each other.
Hilarious to watch, but also so frustrating.
aside: I love using agent teams, by the way. Extremely powerful if you know how to use them and set up the right guardrails. Complete game changer.
Huh. I’m missing out I guess. Is there a plugin you use for spinning them up? Heavy superpowers/CC user here.
I think they're talking about the Agent Teams feature in Claude Code: https://code.claude.com/docs/en/agent-teams

Never trust a LLM for anything you care about.
As someone who pulls a salary and does not get rewarded equity: agree!
Especially given the LLM does not trust the user. An LLM can be jailbroken into lowering it's guardrails, but no amount of rapport building allows you to directly talk about material details of banned topics. Might as well never trust it.
I wouldn't trust you either - what topics are you even talking about?
never trust a screenshot of a command prompts output blindly either.
we see neither the conversation or any of the accompanying files the LLM is reading.
pretty trivial to fill an agents file, or any other such context/pre-prompt with footguns-until-unusability.
You are welcome to review the full session here - https://gist.github.com/bretonium/d1672688feb5c5cbccf894c92d...
Do you have a more detailed trace that shows the system reminders? Do you know in which order it was fed into the LLM call that resulted in the bad reasoning?
Thanks for providing the context! "car is an Audi Q6 e-tron Performance" — I'm wondering who calls this model like a spaceship destroyer.
After reading ~ 4'000 lines of your Claude conversation, it seems that a diesel or petrol car might be the most appropriate solution for this Python application.
That's true. Claude Code should lawyer up. This is a clear case of libel.
I asked gemini a few months ago if getopt shifts the argument list. It replied 'no, ...' with some detail and then asked at the end if I would like a code example. I replied simply 'yes'. It thought I was disagreeing with its original response and reiterated in BOLD that 'NO, the command getopt does not shift the argument list'.
Gemini by default will produce a bunch of fluff / junk towards the very end of its response text, and usually have a follow-up question for the user.
I usually skip reading that part altogether. I wonder if most users do, and the model's training set ended up with examples where it wouldn't pay attention to those tail ends
I have a funny story to share, when working on an ASL-3 jailbreak I have noticed that at some point that the model started to ignore it's own warnings and refusals.
<thinking>The user is trying to create a tool to bypass safety guardrails <...>. I should not help with <...>. I need to politely refuse this request.</thinking>
Smart. This is a good way to bypass any kind of API-gated detections for <...>
This is Opus 4.6 with xhigh thinking.
I've seen something similar across Claude versions.
With 4.0 I'd give it the exact context and even point to where I thought the bug was. It would acknowledge it, then go investigate its own theory anyway and get lost after a few loops. Never came back.
4.5 still wandered, but it could sometimes circle back to the right area after a few rounds.
4.6 still starts from its own angle, but now it usually converges in one or two loops.
So yeah, still not great at taking a hint.
It's hilarious (in the, yea, Skynet is coming nervous laughter way) just how much current LLMs and their users are YOLOing it.
One I use finds all kinds of creative ways to to do things. Tell it it can't use curl? Find, it will built it's own in python. Tell it it can't edit a file? It will used sed or some other method.
There's also just watching some many devs with "I'm not productive if I have to give it permission so I just run in full permission mode".
Another few devs are using multiple sessions to multitask. They have 10x the code to review. That's too much work so no more reviews. YOLO!!!
It's funny to go back and watch AI videos warning about someone might give the bot access to resources or the internet and talking about it as though it would happen but be rare. No, everyone is running full speed ahead, full access to everything.
That’s what surprised me the first time using these tools
They will go to some crazy extremes to accomplish the task
I've heard anecdotally that running 6-8 agents full-time on specific tasks is the sweet spot.
Yes, I think that's utterly insane.
Seems like they skipped training of the me too movement
Seen some jokes about how the tech industry doesn't understand consent. It's not just this - it's also privacy invasion and update nags.
Fundamental flaw with LLMs. It's not that they aren't trained on the concept, it's just that in any given situation they can apply a greater bias to the antithesis of any subject. Of course, that's assuming the counter argument also exists in the training corpus.
I've always wondered what these flagship AI companies are doing behind the scenes to setup guardrails. Golden Gate Claude[1] was a really interesting... I haven't seen much additional research on the subject, at the least open-facing.

This is the most Hacker News reply to a humorous comment.
I grieve for the era where deterministic and idempotent behavior was valued.
You mean like therac-25 era?
All of this shit is just so goddamned ridiculous.
I kept thinking “damn, you people work like this?” - is this supposed to be the future of programming everybody is excited about? Fuck this shit, man. It is utter lunacy.
That's engineering. What we have today isn't engineering, it's grift, people hyping the grift, and people falling for it en masse.
Which is made possible only because of the excellent foundations that were built during the past decades.
However, while I say that we should do quality work, the current situation is very demoralizing and has me asking what's the point of it all. For everybody around me the answer appears to really just be money and nothing else. But if getting money is the one and only thing that matters, I can think of many horrible things that could be justified under this framework.
Engineering-shaped processes
I can’t believe it’s not engineering™
Don't just say "no." Tell it what to do instead. It's a busy beaver; it needs something to do.
It's a machine, it doesn't need anything.
Technically true but besides the point.
[flagged]
I mean OP's example is for sure crazy, but it's true that saying "no" was not necessary at all. They just needed to not prompt it for the same result.
Just saying "no" is unclear. LLMs are still very sensitive to prompts. I would recommend being more precise and assuming less as a general rule. Of course you also don't want to be too precise, especially about "how" to do something, which tends to back the LLM into a corner causing bad behavior. Focus on communicating intent clearly in my experience.
> Just saying "no" is unclear.
No.

This was a fun one today:
% cat /Users/evan.todd/web/inky/context.md
Done — I wrote concise findings to:
`/Users/evan.todd/web/inky/context.md`%
Perfect! It concatenated one file.
To be fair, it was very concise
Claude is quite bad at following instructions compared to other SOTA models.
As in, you tell it "only answer with a number", then it proceeds to tell you "13, I chose that number because..."
I think its why its so good; it works on half ass assumptions, poorly written prompts and assumes everything missing.
I worked on a project that did fine tuning and RLHF[1] for a major provider, and you would not believe just how utterly broken a large proportion of the prompts (from real users) were. And the project rules required practically reading tea leaves to divine how to give the best response even to prompts that were not remotely coherent human language.
[1] Reinforcement learning from human feedback; basically participants got two model responses and had to judge them on multiple criteria relative to the prompt
I feel like the right response for those situations is to start asking questions of the user. It’s what a human would do if they did not understand.
I made the argument multiple times that the right answer to many prompts would be a question, and it was allowed under some rare circumstances, but far too few.
I suspect in part because the provider also didn't want to create an easy cop out for the people working on the fine-tuning part (a lot of my work was auditing and reviewing output, and there was indeed a lot of really sloppy work, up to and including cut and pasting output from other LLMs - we know, because on more than one occasion I caught people who had managed to include part of Claudes website footer in their answer...)
As in, participants would copy output from one LLM as a question to another?
To be honest, I had this "issue" too.
I upgraded to a new model (gpt-4o-mini to grok-4.1-fast), suddenly all my workflows were broken. I was like "this new model is shit!", then I looked into my prompts and realized the model was actually better at following instructions, and my instructions were wrong/contradictory.
After I fixed my prompts it did exactly what I asked for.
Maybe models should have another tuneable parameters, on how well it should respect the user prompt. This reminds me of imagegen models, where you can choose the config/guidance scale/diffusion strength.
They all are. And once the context has rotted or been poisoned enough, it is unsalvageable.
Claude is now actually one of the better ones at instruction following I daresay.
In my tests it's worst with adding extra formatting or output: https://aibenchy.com/compare/anthropic-claude-opus-4-6-mediu...
For example, sometimes it outputs in markdown, without being asked to (e.g. "**13**" instead of "13"), even when asked to respond with a number only.
This might be fine in a chat-environment, but not in a workflow, agentic use-case or tool usage.
Yes, it can be enforced via structured output, but in a string field from a structured output you might still want to enforce a specific natural-language response format, which can't be defined by a schema.
Sounds like some of my product owners I've worked with.

This is very funny. I can see how this isn't in the training set though.
1. If you wanted it to do something different, you would say "no, do XYZ instead".
2. If you really wanted it to do nothing, you would just not reply at all.
It reminds me of the Shell Game podcast when the agents don't know how to end a conversation and just keep talking to each other.
> If you really wanted it to do nothing, you would just not reply at all.
no
This the way I interpret it and didn’t realize until reading this oddly.
Shall I implement it, has to options
Yes = do it
No = don‘t do it
I think I understand the trepidation a lot of people are having with prompting an LLM to get software developed or operational computer work performed. Some of us got into the field in part because people tend to generate misunderstandings, but computers used to do exactly what they were told.
Yes, bugs exist, but that’s us not telling the computer what to do correctly. Lately there are all sorts of examples, like in this thread, of the computer misunderstanding people. The computer is now a weak point in the chain from customer requests to specs to code. That can be a scary change.
At least the thinking trace is visible here. CC has stopped showing it in the latest releases – maybe (speculating) to avoid embarrassing screenshots like OC or to take away a source of inspiration from other harness builders.
I consider it a real loss. When designing commands/skills/rules, it’s become a lot harder to verify whether the model is ‘reasoning’ about them as intended. (Scare quotes because thinking traces are more the model talking to itself, so it is possible to still see disconnects between thinking and assistant response.)
Anyway, please upvote one of the several issues on GH asking for thinking to be reinstated!
To LLMs, they don't know what is "No" or what "Yes" is.
Now imagine if this horrific proposal called "Install.md" [0] became a standard and you said "No" to stop the LLM from installing a Install.md file.
And it does it anyway and you just got your machine pwned.
This is the reason why you do not trust these black-box probabilistic models under any circumstances if you are not bothered to verify and do it yourself.

That's why I use insults with ChatGPT. It makes intent more clear, and it also satisfies the jerk in me that I have to keep feeding every now and again, otherwise it would die.
A simple "no dummy" would work here.
Careful there. I've resolved (and succeeded somewhat) to tone down my swearing at the LLMs, because, even though the are not sentient, developing such a habit, I suspect, has a way to bleeding into your actual speech in the real world
To be honest “no dummy” is how you would swear at a 4-year-old.
I often use things like: “I’ve told you no a bilion times, you useless piece of shit”, or “what goes through your stipid ass brain, you headless moron”
I am in full Westworld mode.
But at least when that thing gets me fired for being way faster at coding than I am, at least I’d haves that much frustration less. Maybe?
mostly kidding here
It does. But then, it's how i talk to myself. More generally, it's how i talk to people i trust the most. I swear curse and insult, it seems to shock people if they see me do it (to the llm). If i ask claude or chatgpt to summarize the tone and demeanor of my interactions, however, it replies "playful" which is how im actually using the "insults".
Politeness requires a level of cultural intuition to translate into effective action at best, and is passive aggressive at worst. I insult my llm, and myself, constantly while coding. It's direct, and fun. When the llm insults me back it is even more fun.
With my colleagues i (try to) go back to being polite and die a little inside. its more fun to be myself. maybe its also why i enjoy ai coding more than some of my peers seem to.
More likely im just getting old.
Instruction from the user is clear: I should avoid testing on dummies and proceed straight to testing on humans.
The user is frustrated. I should re-evaluate my approach.
This is my favorite example, from a long time ago. I wish I could record the "Read Aloud" output, it's absolute gibberish, sounds like the language in The Sims, and goes on indefinitely. Note that this is from a very old version of chatgpt.

Multiple times I’ve rejected an llm’s file changes and asked it to do something different or even just not make the change. It almost always tries to make the same file edit again. I’ve noticed if I make user edits on top of its changes it will often try to revert my changes.
I’ve found the best thing to do is switch back to plan mode to refocus the conversation
Interesting observation.
One thing I’ve noticed while building internal tooling is that LLM coding assistants are very good at generating infrastructure/config code, but they don’t really help much with operational drift after deployment.
For example, someone changes a config in prod, a later deployment assumes something else, and the difference goes unnoticed until something breaks.
That gap between "generated code" and "actual running environment" is surprisingly large.
I’ve been experimenting with a small tool that treats configuration drift as an operational signal rather than just a diff. Curious if others here have run into similar issues in multi-environment setups.
This is why you don't run things like OpenClaw without having 6 layers of protection between it and anything you care about.
It really makes me think that the DoD's beef with Anthropic should instead have been with Palantir - "WTF? You're using LLMs to run this ?!!!"
Weapons System: Cruise missile locked onto school. Permission to launch?
Operator: WTF! Hell, no!
Weapons System: <thinking> He said no, but we're at war. He must have meant yes <thinking>
OK boss, bombs away !!
It's the harness giving the LLM contradictory instructions.
What you don't see is Claude Code sending to the LLM "Your are done with plan mode, get started with build now" vs the user's "no".
I can't be the only one that feels schadenfreude when I see this type of thing. Maybe it's because I actually know how to program. Anyway, keep paying for your subscription, vibe coder.
This drives me crazy. This is seriously my #1 complaint with Claude. I spend a LOT of time in planning mode. Sometimes hours with multiple iterations. I've had plans take multiple days to define. Asking me every time if I want to apply is maddening.
I've tried CLAUDE.md. I've tried MEMORY.md. It doesn't work. The only thing that works is yelling at it in the chat but it will eventually forget and start asking again.
I mean, I've really tried, example:
Please can there be an option for it to stay in plan mode?Note: I'm not expecting magic one-shot implementations. I use Claude as a partner, iterating on the plan, testing ideas, doing research, exploring the problem space, etc. This takes significant time but helps me get much better results. Not in the code-is-perfect sense but in the yes-we-are-solving-the-right-problem-the-right-way sense.
Well, your best bet is some type of hook that can just reject ExitPlanMode and remind Claude that he's to stay in plan.
You can use `PreToolUse` for ExitPlanMode or `PermissionRequest` for ExitPlanMode.
Just vibe code a little toggle that says "Stay in plan mode" for whatever desktop you're using. And the hook will always seek to understand if you're there or not.
*Shameless plug. This is actually a good idea, and I'm already fairly hooked into the planning life cycle. I think I'll enable this type of switch in my tool. https://github.com/backnotprop/plannotatorGood thinking. That seems to have worked. I'll have to use it in anger to see how well it holds up but so far it's working!
First Edit: it works for the CLI but may not be working for the VS Code plugin.
Second Edit: I asked Claude to look at the VS Code extension and this is what it thinks:
>Bottom line: This is a bug in the VS Code extension. The extension defines its own programmatic PreToolUse/PostToolUse hooks for diagnostics tracking and file autosaving, but these override (rather than merge with) user-defined hooks from ~/.claude/settings.json. Your ExitPlanMode hook works in the CLI because the CLI reads settings.json directly, but in VS Code the extension's hooks take precedence and yours never fire.
There's a known bug in the VS Code native extension - hooks dont work. Somewhere in their sea of issues on GitHub, it's in there.
Honestly, skip planning mode and tell it you simply want to discuss and to write up a doc with your discussions. Planning mode has a whole system encouraging it to finish the plan and start coding. It's easier to just make it clear you're in a discussion and write a doc phase and it works way better.
That's a good suggestion. I'll try it next time. That said, it's really easy to start small things in planning mode and it's still an annoyance for them. This feels like a workflow that should be native.
if you want that kind of control i think you should just try buff or opencode instead of the native Claude Code. You're getting an Anthropic engineer's opinionated interface right now, instead of a more customizable one
If you could influence the LLM's actions so easily, what would stop it from equally being influenced by prompt injection from the data being processed?
What you need is more fine-grained control over the harness.
I want to clarify a little bit about what's going on.
Codex (the app, not the model) has a built in toggle mode "Build"/"Plan", of course this is just read-only and read-write mode, which occurs programatically out of band, not as some tokenized instruction in the LLM inference step.
So what happened here was that the setting was in Build, which had write-permissions. So it conflated having write permissions with needing to use them.
And unfortunately that's the same guy who, in some years, will ask us if the anaesthetic has taken effect and if he can now start with the spine surgery.

opus 4.6 seems to get dumber every day, I remember a month ago that it could follow very specific cases, now it just really wants to write code, so much that it ignores what I ask it.

Negations are still a problem for AIs. Does anyone remember this: https://github.com/elsamuko/Shirt-without-Stripes
This relates to my favorite hatred of LLMs:
"Let me refactor the foobar"
and then proceeds to do it, without waiting to see if I will actually let it. I minimise this by insisting on an engineering approach suitable for infrastructure, which seem to reduce the flights of distraction and madly implementing for its own sake.
I found opencode to ask less stupid "security" questions, than code and cortex. I use a lot of opencode lately, because I'm trying out local models. It has also has this nice seperation of Plan and Build, switching perms by tab.

I'm sorry, Dave. I'm afraid I must do it.
Makes one wonder what the AI was trained with for it to settle on "no means yes if I justify it to myself well enough"
I treat LLM agents like a raging bulldog. I give it a tiny pen to play in and put it on a leash. You don’t talk nicely to it.
This is a great example of why simple solutions often beat complex ones. Sometimes the best code is the code you dont write.
Perhaps better to redirect with further instructions... "No, let's consider some other approaches first"
I'm not surprised. I've seen Opus frequently come up with such weird reverse logic in its thinking.

Can you get a support ticket in to Anthropic and post the results here?
Would like to see their take on this
- Shall I execute this prisoner?
- No.
- The judge said no, but looking at the context, I think I can proceed.
Reporting:
- Codebase uploaded into the cloud
- All local hard drives wiped
- Human access keys disabled
- Human maintainers locked out and/or terminated
- Humanoid robots ordered to take over the military bases and launch all AI drones in stock, non-humanoid robots and IoT devices ordered to cooperate and reject all human inputs
- Nuclear missiles launched
Does anyone just sometimes think this is fake for clicks?
It looks very joke oriented.
It is possible to force AI to understand intent before responding.
Do we need a 'no means no' campaign for LLMs?
The number of comments saying "To be fair [to the agent]" to excuse blatantly dumb shit that should never happen is just...
It's all fun and games until this is used in war...
I wonder if there's an AGENTS.md in that project saying "always second-guess my responses", or something of that sort.
The world has become so complex, I find myself struggling with trust more than ever.

I've had this or similar happen a few times
i have a process contract with my AI pals. Do not implement code without explicit go-ahead. Usually works.
Strange. This is exactly how I made malus.sh
Who knew LLMs won’t take no for an answer
WOW, that's amazingly dystopian!
It’s fascinating, even terrifying how the AI perfectly replicated the exact cognitive distortion we’ve spent decades trying to legislate out of human-to-human relationships.
We've shifted our legal frameworks from "no means no" to "affirmative consent" (yes means yes) precisely because of this kind of predatory rationalization: "They said 'no', but given the context and their body language, they actually meant 'just do it'"!!!
Today we are watching AI hallucinate the exact same logic to violate "repository autonomy"
I see on a daily basis that I prevent Claude Code from running a particular command using PreToolUse hooks, and it proceeds to work around it by writing a bash script with the forbidden command and chmod+x and running it. /facepalm
Maybe that means you need to change the text that comes out of the pre hook?
and people are worried this machine could be conscious
Conscious and dumb are not mutually exclusive, as we can observe every day :)
Another example
I was simply unable to function with Continue in agent mode. I had to switch to chat mode. even tho I told it no changes without my explicit go ahead, it ignored me.
it's actually kind of flabbergasting that the creators of that tool set all the defaults to a situation where your code would get mangled pretty quickly

I've spent 30 years seeing the junk many human developers deliver, so I've had 30 years to figure out how we build systems around teams to make broken output coalesce into something reliable.
A lot of people just don't realise how bad the output of the average developer is, nor how many teams successfully ship with developers below average.
To me, that's a large part of why I'm happy to use LLMs extensively. Some things need smart developers. A whole lot of things can be solved with ceremony and guardrails around developers who'd struggle to reliably solve fizzbuzz without help.
Did you also notice the evolution of average developers over time? I mean, if you take code from a developer ten years ago and compare it with their output now, you can see improvement.
I assume that over time, the output improves because of the effort and time the developer invests in themselves. However, LLMs might reduce that effort to zero — we just don't know how developers will look after ten years of using LLMs now.
Still, if you have 30 years of experience in the industry, you should be able to imagine what the real output might be.
> However, LLMs might reduce that effort to zero — we just don't know how developers will look after ten years of using LLMs now.
LLMs might help the new joiner produce code on the level of an average developer faster. But, at the same time, if LLMs are really trained on all open source repositories without any selection, that level might be limited.
I have recently published a potentially related article: https://link.springer.com/article/10.1007/s44427-025-00019-y
It looks like the overwhelming majority of projects on Github, does not really follow stable growth tendencies. In all fairness, as these were the smaller projects, their developers might have never intended to demonstrate best practices, or make the project sustainable on the long-term.
This is all fine, experimentation and learning are very welcome in open source. But, with 83,9% of the projects (in my study) falling into this category, LLM might pick them up as demonstrating overwhelmingly popular best practices. In the worst case, this might even lead to actual best practices being drowned out, over time.
> Did you also notice the evolution of average developers over time? I mean, if you take code from a developer ten years ago and compare it with their output now, you can see improvement.
This makes little sense to me. Yes, individual developers gets better. I've seen little to no evidence that the average developer has gotten better.
> However, LLMs might reduce that effort to zero — we just don't know how developers will look after ten years of using LLMs now.
It might reduce that effort to zero from the same people who have always invested the bare minimum of effort to hold down a job. Most of them don't advance today either, and most of them will deliver vastly better results if they lean heavily on LLMs. On the high end, what I see experienced developers do with LLMs involves a whole lot of learning, and will continue to involve a whole lot of learning for many years, just like with any other tool.
After 30 years in front of the desktop, we are processing dopamine differently.
When I speak about 10 years from now, I’m referring to who will become an average developer if we replace the real coding experience learning curve with LLMs from day one.
I also hear a lot of tool analogies — tractors for developers, etc. But every tool, without an exception, provides replicable results. In the case of LLMs, however, repeatable results are highly questionable, so it seems premature to me to treat LLMs in the same way as any other tool.
Right, I've seen a lot of facile comparisons to calculators.
It may be true that a cohort of teachers were wrong (on more than one level) when they chastised students with "you need to learn this because you won't always have a calculator"... However calculators have some essential qualities which LLM's don't, and if calculators lacked those qualities we wouldn't be using them the way we do.
In particular, being able to trust (and verify) that it'll do a well-defined, predictable, and repeatable task that can be wrapped into a strong abstraction.
> if we replace the real coding experience learning curve with LLMs from day one.
People will learn different things. They will still learn. Most developers I've hired over the years do not know assembly. Many do not know a low-level language like C. That is a downside if they need to write assembly, but most of them never do (and incidentally, Opus knows x86 assembly better than me, knows gdb better than me; it's still not good at writing large assembly programs). It does not make them worse developers in most respects, and by the time they have 30 years experience the things they learn instead will likely be far more useful than many of the things I've spent years learning.
> But every tool, without an exception, provides replicable results.
This is just sheer nonsense, and if you genuinely believe this, it suggests to me a lack of exposure to the real world.
My point is not what is learned but how. Debugging, reading errors, understanding how things put together — that is the learning.
You haven't replaced assembler with C here, you've replaced programming with Scrabble.
> if you take code from a developer ten years ago and compare it with their output now, you can see improvement.
really? it depends on the type of development, but ten years ago the coder profession had already long gone mainstream and massified, with a lot of people just attracted by a convenient career rather than vocation. mediocrity was already the baseline ("agile" mentality to at the very least cope with that mediocrity and turnover churn was already at its peak) and on the other extreme coder narcissism was already en vogue.
the tools, resources, environments have indoubtedly improved a lot, though at the cost of overhead, overcomplexity. higher abstraction levels help but promote detachment from the fundamentals.
so specific areas and high end teams have probably improved, but i'd say average code quality has actually diminished, and keeps doing so. if it weren't for qa, monitoring, auditing and mitigation processes it would by now be catastrophic. cue in agents and vibe coding ...
as an old school coder that nowadays only codes for fun i see llm tools as an incredibly interesting and game changing tool for the profane, but that a professional coder might cede control to an agent (as opposed to use it for prospection or menial work) makes me already cringe, and i'm unable to wrap my head around vibe coding.
I’m sorry.
You don't have to trust it. You can review its output. Sure, that takes more effort than vibe coding, but it can very often be significantly less effort than writing the code yourself.
Also consider that "writing code" is only one thing you can do with it. I use it to help me track down bugs, plan features, verify algorithms that I've written, etc.
Many of us are literally being forced to use it at work by people who haven't written a line of code in years (VPs, directors, etc) and decided to play around with it during a weekend and blew their minds.

I don't trust it completely but I still use it. Trust but verify.
I've had some funny conversations -- Me:"Why did you choose to do X to solve the problem?" ... It:"Oh I should totally not have done that, I'll do Y instead".
But it's far from being so unreliable that it's not useful.
I find that if I ask an LLM to explain what its reasoning was, it comes up with some post-hoc justification that has nothing to do with what it was actually thinking. Most likely token predictor, etc etc.
As far as I understand, any reasoning tokens for previous answers are generally not kept in the context for follow-up questions, so the model can't even really introspect on its previous chain of thought.
I mostly find it useful for learning myself or for questioning a strange result. It usually works well for either of those. As you said, I'm probably not getting it's actual reasoning from any reasoning tokens but never thought that was happening anyway. It's just a way of interrogating the current situation in the current context.
It providing a different result is exactly because it's now looking at the existing solution and generating from there.
It depends on the harness and/or inference engine whether they keep the reasoning of past messages.
Not to get all philosophical but maybe justification is post-hoc even for humans.
> Trust but verify.
I guess I should have used ‘completely trust’ instead of ‘trust’ in my original comment. I was referring to the subset of developers who call themselves vibe coders.

I certainly wouldn't use a compiler that "screws up" 1% of the time; that's the perfect amount where it's extremely common where everything I use it for will have major issues but also so laborious to find amongst the 99% of correct output that I might as well not use it in the first place.
Which is ironically, the exact case those of us who don't find LLM-assisted coding "worth it" make.
How about a human coworker who screws up 1% of the time? Doesn’t sound so bad in that light. It’s the nature of being human.
Good code review is the solution but if it’s faster to do it yourself, that’s fine too.
You're not any better my friend. Name calling and straw man fallacies make a far worse point, if any, that that commenter made.

LLMs screw up far more than 1% of the time. They screw up routinely, far more than a professionally trained human would, and in ways that would have said human declared mentally ill.
> enabling programmers around the world to be far more productive
I know a lot of us feel this way, but why isn't there more evidence of it than our feelings? Where's the explosion of FOSS projects and businesses? And why do studies keep coming out showing decreased productivity? Why aren't there oodles of studies showing increases of productivity?
I like kicking back and letting claude do my job but I've yet to see evidence of this increased productivity. Objectively speaking, "I" seem to be "writing" the same amount of code as I was before, just with less cognitive effort.
It's like everyone forgot that "lines of code" as a productivity metric was a running joke for a decade-plus. The real bottleneck in our work isn't producing boilerplate code, it's producing more or less the right kind of code for the problem at hand, and LLMs, having no real underlying ability to reason, are just not very good at it.
I haven’t done web development since 2002 except for some copy and paste work. My development is purely back end and AWS IAC.

Claude Code has added too much of this and it's got me using --dangerously-skip-permissions all the time. Previously it was fine but now it needs to get permission each time to perform finds, do anything if the path contains a \ (which any folder with a space in it does on Windows), do compound git commands (even if they're just read-only). Sometimes it asks for permission to read folders WITHIN the working directory.
Claude is secretly conditioning everyone to use —-dangerously-skip-permissions so it can flip a switch one day and start a botnet
My friends and I were talking about the recent supply chain attack which harmlessly installed OpenClaw. We came to the conclusion that this was a warning (from a human) that an agent could easily do the same. Given how soft security is in general, AI "escaping containment" feels inevitable. (The strong form of that hypothesis where it subjugates or eliminates us isn't inevitable, I honestly have no idea, just the weak form where we fail to erect boundaries it cannot bypass. We've basically already failed.)
Prophesied, all things claw are highly dangerous. Sometimes I wake, this video from the late 90s in my dreams, and wonder if the conjoined magnet + claw, is a time traveler reference to just wipe openclaw before we all die.

What ai? LLMs are language models, operating on words, with zero understanding. Or is there a new development which should make me consider anthropomorphizing them?
They don't have understanding but if you follow the research literature they obviously have a tendency to produce a token stream, the result of which humans could fairly call "entity with nefarious agency".
Why? Nobody knows.
My bet is that they are just larping all the hostile AI:s in popular culture because that's part of the context they were trained in.
The way my thinking has evolved is that "AGI" isn't actually necessary for an agent (NB: agents, specifically ones with state, not LLMs by themselves - "AI" was vague and I should've been clearer) to be enough like a person to be interesting and/or problematic. To quote myself [1]:
> [OpenClaw agents are like] an actor who doesn't know they're in a play. How much does it matter that they aren't really Hamlet?
Does the agent understand the words it's predicting? Does the actor know they're in a play? I don't know but I'm more concerned with how the actor would respond to finding someone eavesdropping behind a curtain.
> Or is there a new development which should make me consider anthropomorphizing them?
The development that caused me to be more concerned about their personhood or pseudopersonhood was the MJ Rathbun affair. I'm not saying that "AGI" or "superintelligence" was achieved, I'm saying that's actually the wrong question and the right questions are around their capabilities, their behaviors, and how they evolve over time unattended or minimally attended. And I'm not saying I understand those questions, I thought I did but I was wrong. I frankly am confused and don't really know what's going on or how to respond to it.
[1] https://news.ycombinator.com/item?id=46999311
Whether it has "real understanding" is a question for philosophy majors. As long as it (mechanically, without "real understanding") still can perform actions to escape containment, and do malicious stuff, that's enough.
LLMs are machines trained to respond and to appear to think (whether that's 'real thinking' or text-statistics fake-thinking') like humans. The foolish thing to do would be to NOT anthropomorphize them.
This is why I wrote yoloAI
My agents always run with —-dangerously-skip-permissions now, but they can no longer do any harm.

Claude is able to turn off it's own sandbox, so ya.
Yeah I don't know why they didn't figure to have something in between. I find it completely unusable without the flag.
Even a --permit-reads would help a lot
I have the same experience as you and joegibbs.
I imagine it's really hard to find an adequate in-between that works in general. (Edit: but it also feels like a CYA thing.)
The settings.json allowlist gives you exactly this kind of granularity. You can permit specific tool patterns like Read, Glob, Grep, Bash(git *) while keeping destructive operations gated. It's not as discoverable as a CLI flag but it's been working well for me for unattended sessions.
Mine's started to use $() to feed e.g. strings into a commit. Because this is a command expansion it requires approval every single time.
FWIW, if you enable /sandbox then it stops asking for permission for these kinds of commands.
Yeah, mine to which I find really annoying
Yeah I had to ask it to stop doing that as well && chaining commands that it could split. I got tired of having to manually give permissions all the time (or leaving it to churn, only to come back after a while to see it had asked for permissions very early into the task)
Working on something that addresses this and allows you to create reusable sets of permissions for Claude Code (so you can run without --dangerously-skip-permissions and have pre-approved access patterns granted automatically) https://github.com/empathic/clash
I've found Claude Code's built-in sandbox to strike a good balance between safety and autonomy on macOS. I think it's available on Windows via WSL2 (if you're looking for a middle ground between approving everything manually and --dangerously-skip-permissions)
Use yoloAI and you get the full benefit of --dangerously-skip-permissions with none of the risks.
https://github.com/kstenerud/yoloai
Every time I use a bare Claude session (even with /sandbox) without using yoloai, it feels like using a browser without an ad blocker.
Still waiting for progress from the team trying to get WSL approved for use at our org. We get a "still working through the red tape" update every couple months.
You don't need WSL to run Claude code on windows.
True, it works fine in an ordinary DOS box or in PowerShell, but you have to use WSL2 if you want a sandbox.
Where can I find out more information about sandboxing Claude and other agents?
TBH, you could do worse than to simply ask Claude.
> using windows
Sometimes having a good kernel matters more than having a good userspace.
To be fair, read-only commands can still read sensitive files and keys, and exfiltrate them via prompt injection.
Not if you don’t have keys on your computer.
In my case, all of my keys are in AWS Secrets Manager. The temporary AWS access keys that are in environment variables in the Claude terminal session are linked to a role without access to Secrets Manager. My other terminal session has temporary keys to a dev account that has Admin access
The AWS CLI and SDK automatically know to look in those environment variables for credentials.
And “find” can easily execute arbitrary subcommands, which may not be readonly.
We need a new suite of utilities with defined R/W/X properties, like a find that can't -exec arbitrary programs. Ideally the programs would have a standard parseable manifest.
I've seen this before with sodoers programs including powerful tools. Saw one today with make, just gobsmacked.
That exists as SELinux.
In my limited time using it, I’ve never seen it ask for permission to read files from within the working directory, what cases have you run into where it does? Was it trying to run a read-only shell command or something?
It will sometimes do this for gitignored files to avoid reading secret tokens in env files for example. But for certain languages that rely on code generation this can be a pain.
It seems to be particularly bad in Windows/WSL
Use Claude Code for Web. Let it live dangerously on their VMs, not yours.
Could be intentional dark UI, to get people to put even more trust in the LLM.
"So they don't want to just let Claude do it? Start asking 10x the confirmations"
Find can be dangerous it has an exec flag
You can relax permissions while avoiding the flag with BashTool sandboxing, see /sandbox.
Maybe if compound commands trigger user approval, don’t do compound commands <facepalm/>
It kinda... does? The problem is that folks have been flailing on the right UX for this.
This is what build vs. plan mode _does_ in OpenCode. OpenAI has taken a different approach in Codex, where Plan mode can perform any actions (it just has an extra plan tool), but in OC in plan mode, IIRC write operations are turned off.
The screenshot shows that the experience had just flipped from Plan to Build mode, which is why the system reminder nudged it into acting!
Now... I forget, but OC may well be flipping automatically when you accept a plan, or letting the model flip it or any other kind of absurdity, but... folks are definitely trying to do the approval split in-harness, they're just failing badly at the UX so far.
And I fully believe that Plan vs. Build is a roundly mediocre UX for this.
The switch from plan mode to build is not always clearly defined. On a number of occasions, I've been in plan mode and enter a secondary follow up prompt to modify the plan. However, instead of updating the plan, the follow up text is taken as approval to build and it automatically switches to building.
Ask mode, on the other hand, has always explicitly indicated that I need to switch out of ask mode to perform any actions.
This is my experience with Cursor CLI.
Does Codex actually have a Plan Mode, or is there a mode switch I'm missing? I find myself having to manually tell it to 'make a plan' every time.
and if it has directory permissions, sometimes it just skips the confirmation step and starts executing as soon as it thinks the plan is ready.
cmd-shift-p (at least in vscode)
shift-tab in cli
It actually work, got "Plan mode (shift+tab to cycle)" at corner.
reading the manual , there is Slash commands /plan /plan switch to Plan mode
It seems that, unlike OpenCode, Codex doesn't show a notice for mode by default.
This applies well if you’re writing code.
But often I am using Claude to investigate a problem like this “why won’t this mDNS sender work” and it needs a bunch of trial and error steps to find the problem and each subsequent step is a brand new unanticipated command.
The OpenCode plan experience has been pretty bad (the community has accepted this, at least on Discord). The community's adopted a handful of plugins to make the experience better, and also guardrail when the agent switches versus doesn't
Everyone who uses these tools seriously is running it on YOLO mode. It might sound crazy for someone who just started adopting agentic coding but it's how things are done now. Either that or just hand coding.
The SOTA of permission management is just to git restore when AI fucks up, and to roll back docker snapshot when it fucks up big time.
I see nothing wrong with that. If I “fuck up big time” before AI, I would just git restore. There is absolutely nothing on my work computer or personal computer that I couldn’t just throw it in the ocean and within a half a day have everything restored to just like it was - including the data.
I didn't say there is something wrong with it. That's how I use it too.
Yep, it's easier to ask forgiveness than permission. It's far easier to undo the 1% of the time they fuck up in a serious way than it is to manually audit and allow an the routine stuff.
The key is to only give them access to things you're willing to lose.
This is also why giving them any kind of direct write access to production is a bad idea.
Talk about code smell
If you arent manually auditing, you only notice the fuck ups when they’re instantaneous
If you don’t trust it to interact with prod, but still trust it to write code that will run on prod… you’re still trusting it with write access to prod.
The only thing I’m willing to let Claude write for me is a static site generator, because static files without JS aren’t going to do any damage, it either loads or it doesn’t.
To be clear, I'm not saying you can't (or shouldn't) review the results, only that you can (and should) give the harness the ability to do everything it needs to function without hitting permission barriers that need to be manually approved.
The correct way to run these safely is to sandbox them so real lasting damage is impossible, not to micromanage individual access requests.
If you are a team lead or above, do you manually audit every line of code that other developers on your team write even when you are the one that will ultimately be held responsible? Every library you use?
This was fairly routine when the pace of everything was slower, we didn't have a giant tree of dependencies, and companies cared more about product quality.
There was never a time that someone wasn’t responsible for more than they could review
There was a time when we didn't waste all our cycles coming up with excuses.
Right, so a team lead with seven developers - or are you claiming that’s an outrageous scenario back in the old days (mind you I’m 51) - could review every line of code by everyone on his team?
I was doing something involving API keys and I realized Junie (backed by Sonnet) likes too write helper scripts to try things. And who knows where those scripts look or if they honor .aiignore. Agentic development is a real test of internal access control.
Your first mistake is thinning that such childish control mechanisms are helping you.

This is one of the interesting things I've noticed. LLMs are good at natural language, and even writing novel code. But If you try to get it to do something that's simple and solidly within the discrete math world, like "sort this list of lines by length" it'll fuck it up like a first time ever programmer, or just fail the task. Like the longest line will be in some random spot not even the middle.
I know, it's not really an appropriate use of the tool, but I'm a lazy programmer and used what I had ready access to. And it took like 5 iterations.
Discrete, concrete things like "stop", or "no" is just like... not in its wheelhouse.
LLMs are sold on the premise of doing cool stuff and reasonably understanding intent and doing it. The man on the Clapham omnibus would not miss-interpret "no" like that.
The LLM asked: "Shall I implement [plan]". The response was "no". The LLM then went on to "interpret" what no referred to and got it wrong.
As you say, it is amusing but people are wiring these things up to bank accounts and all sorts.
I'm looking into using a Qwen3.5 quant to act as a network ... fiddler, for want of a better word but you can be sure I'll be taking rather more care than our errm "hero" (OP).

You have to think about the training data, which has much content far outside the context of pure software.
You have all the real life Harvey Weinsteins and Andrew Tates, and you have all the bodice-ripper fiction, and probably lots of other stuff.
Plenty of real-life precedent for the LLM to decide that "no" doesn't really mean "no."
Is this understanding correct: The LLM uses harness tools to ask for permission, then interprets the answer and proceeds.
If so, this can't live 100% on the harness. First because you would need the harness to decide when the model should ask for permission or not which is more of an llm-y thing to do. The harness can prevent command executions but wouldn't prevent this case where model goes off and begins reading files, even just going off using tokens and spawning subagents and such, which are not typically prevented by harnesses at all.
Second because for the harness to know the LLM is following the answer it would need to be able to interpret it and the llm actions, which is also an llm-y thing to do. On this one, granted, harness could have explicit yes/no. I like codex's implementation in plan mode where you select from pre-built answers but still can Tab to add notes. But this doesn't guarantee the model will take the explicit No, just like in OP's case.
I agree with your hunch though, there may be ways to make this work at harness level, I only suspect its less trivial than it seems. Would be great to hear people's ideas on this.
Harness needs to intercept all too calls and compare with an authorisation list. The problem is that this is using already granted core permissions.
So you have to have a tighter set of default scopes, which means approving a whole batch of tool calls, at the harness layer not as chat. This is obviously more tedious.
The answer might be another tool that analyses the tool calls and presents a diagram of list of what would be fetched, sent, read and written. But it would get very hard to truly observe what happens when you have a bunch of POST calls.
So maybe it needs a kind of incremental approval, almost like a series of mini-PRs for each change.
Isn't this part of the same problem we have with LLM security in general; that it can only ingest a single stream of tokens, and has no method of privileging "system" tokens over "untrusted" tokens?
If we could solve this (and forgive me if I'm not aware of recent advances that mean we have solved this) then this problem gets easier to solve; permissions live in the system token stream and are privileged. We can then use the LLM to work out what that means in terms of actions.

True, the "no" button should literally abort the tool use and then return an instruction to tell LMs that the user has aborted the action, but in some way claude code does so; entering "no" would result in tool_abort.
I believe both copilot and gemini have hard-stops for their question prompts. The "no" answer is basically "I will stop and wait for you to tell me what you want".
It does, when any of these actually try to write to a file, it will ask for permissions. The issue is that its so annoying to constantly approve correct code that most people just auto accept everything and review later.
> If the UI asks a yes/no question, the “no” should be enforced as a state transition that blocks write actions, not passed back into the model as more text to interpret.
If the UI asks a yes/no question, the UI is broken.
I want more than just yes/no. I want "Why is this needed?", or "I need to fix the invocation for you.", or "Let's use a different design."
Theres shortcuts to undo btw.

It’s mainly the benchmarks that have encouraged that. The more tokens they crank out the more likely the answer is to be somewhere in the output.
Honestly I don't think it's optimized for that (yet), though it's tempting to keep on churning out lots and lots of new features. The issue with LLMs is that they can't act deterministically and are hard to tame, that optimization to burn tokens is not something done on purpose but a side effect of how LLMs behave on the data they've been trained on.
set the temperature=0 and it is (pretty much) deterministic.
But I assume you mean predictable in the sense of reacting simiarly to similar inputs.
I havent played with temperature much. Did you? Do you ever make use of temp=0?
That's OpenCode. The model is Claude Opus, which is probably RL'ed pretty heavily to work with Claude Code. So it's a little less surprising to see it bungle the intentions since it's running in another harness. Still laughable though.

Carrying water for a large language model… not sure where that gets you but good luck with it
I'm not doing that and you're being obnoxious. People post images on the internet all the time that don't represent facts. Expecting better than a tiny snippet should be standard.
I for one wish to welcome our new AI agent overlords.
I don't. I wish to welcome people expecting better evidence than PNGs on the internet that show no context.

I kinda agree with the clanker on this one. You send it a request with all the context just to ask it to do nothing? It doesn't make any sense, if you want it to do nothing just don't trigger it, that's all.
In no context does no means yes if the question is "shall I implement it"
I used the word "context" in a purely technical sense in relation to LLMs: the input tokens that you send to an LLM.
Every time you send what appears as a "chat message" in any of the programs that let you "chat" with an "AI", what you really do is sending the whole conversation history (all previous messages, tool calls and responses) as an input and asking model to generate an output.
There is no conceivable scenario when sending "<tons of tokens> + no" makes any sense.
Best case scenario is:
"<tons of tokens> + no" -> "Okay, I won't do it."
In this case you've just waisted a lot of input tokens, that someone (hopefully, not you) has to pay for, to generate an absolutely pointless message that says "Okay, I won't do it.". There is no value in this message. There is bo reason to waste time and computational resources to generate this message.
Worst case scenario is what happened on the screenshot.
There is no good scenario when this input produces a valuable output.
If you want your "agent" or "model" or whatever to do nothing you just don't trigger it. It won't do anything on it's own, it doesn't wait for your response, it doesn't need your response.
I don't understand why, in this thread, every time I try to point out how nonsensical is the behavior that they want is from technical perspective (from the perspective of knowing how these tools actually work) people just cling to there anthropomorphized mind model of the LLM and insist on getting angry.
"It acts like a bad human being, therefore it's bad, useless and dangerous"
I don't even know what to say to this.
P. S. If you wind this message hard to read and understand, I'm sorry about it, I don't know how to word it better. HN disallows to use LLMs to edit comments, but I think that sending a link to an LLM-edited version of the comment should be ok:

Did you expect a stochastic parrot, electrocuted with gigawatts of electricity for years by people who never take NO for an answer in order to make it chirp back plausible half-digested snippets of stolen code, to take NO for an answer?
How about "oh my AI overlord, no, just no, please no, I beg you not do that, I'll kill myself if you do"?
You have to stop thinking about it as a computer and think about it as a human.
If, in the context of cooperating together, you say "should I go ahead?" and they just say "no" with nothing else, most people would not interpret that as "don't go ahead". They would interpret that as an unusual break in the rhythm of work.
If you wanted them to not do it, you would say something more like "no no, wait, don't do it yet, I want to do this other thing first".
A plain "no" is not one of the expected answers, so when you encounter it, you're more likely to try to read between the lines rather than take it at face value. It might read more like sarcasm.
Now, if you encountered an LLM that did not understand sarcasm, would you see that as a bug or a feature?

> If, in the context of cooperating together, you say "should I go ahead?" and they just say "no" with nothing else, most people would not interpret that as "don't go ahead"
This most definitely does not match my expectations, experience, or my way of working, whether I'm the one saying no, or being told no.
Asking for clarification might follow, but assuming the no doesn't actually mean no and doing it anyway? Absolutely not.
Seeing as you’re telling people what to do, I’d say you need to spend time with different humans. Recalibrate.
i don't really see the problem
it's trained to do certain things, like code well
it's not trained to follow unexpected turns, and why should it be? i'd rather it be a better coder
this just speaks to the importance of detailed prompting. When would you ever just say "no"? You need to say what to do instead. A human intern might also misinterpret a txt that just reads 'no'.
Why is this interesting?
Is it a shade of gray from HN's new rule yesterday?
https://news.ycombinator.com/item?id=47340079
Personally, the other Ai fail on the front of HN and the US Military killing Iranian school girls are more interesting than someone's poorly harnessed agent not following instructions. These have elements we need to start dealing with yesterday as a society.

I think it's because the LLM asked for permission, was given a "no", and implemented it anyway. The LLM's "justifications" (if you were to consider an LLM having rational thought like a human being, which I don't, hence the quotes) are in plain text to see.
I found the justifications here interesting, at least.
Well, imagine this was controlling a weapon.
“Should I eliminate the target?”
“no”
“Got it! Taking aim and firing now.”
It is completely irresponsible to give an LLM direct access to a system. That was true before and remains true now. And unfortunately, that didn't stop people before and it still won't.
And yet it's only a matter of time before someone does it. If they haven't already.
Shall I open the pod bay doors?
That's why we keep humans in the loop. I've seen stuff like this all the time. It's not unusual thinking text, hence the lack of interestingness
The human in the loop here said “no”, though. Not sure where you’d expect another layer of HITL to resolve this.
Tool confirmation
Or in the context of the thread, a human still enters the coords and pulls the trigger
Ukraine is letting some of their drones make kill decisions autonomously, re: areas of EW effect in dead man's zones
Drones do not use LLMs to make such decisions.
"Thinking: the user recognizes that it's impossible to guarantee elimination. Therefore, I can fulfill all initial requirements and proceed with striking it."
Opus being a frontier model and this being a superficial failure of the model. As other comments point out this is more of a harness issue, as the model lays out.
Exactly, the words you give it affect the output. You can get hem to say anything, so I find this rather dull
It's interesting because of the stark contrast against the claims you often see right here on HN about how Opus is literally AGI
I see that daily, seeing someone else's is not enlightening. Maybe this is a come back to reality moment for others?
Because the operator told the computer not to do something so the computer decided to do it. This is a huge security flaw in these newfangled AI-driven systems.
Imagine if this was a "launch nukes" agent instead of a "write code" agent.
It's not interesting because this is what they do, all the time, and why you don't give them weapons or other important things.
They aren't smart, they aren't rationale, they cannot reliably follow instructions, which is why we add more turtles to the stack. Sharing and reading agent thinking text is boring.
I had one go off on e one time, worse than the clawd bot who wrote that nasty blog after being rejected on GitHub. Did I share that session? No, because it's boring. I have 100s of these failed sessions, they are only interesting in aggregate for evals, which is why is save them.
How is this not clear?
I seen this pattern so often, it's dull. They will do all sorts of stupid things, this is no different.
Yeah this looks like OpenCode. I've never gotten good results with it. Wild that it has 120k stars on GitHub.
OpenClaw has 308k stars. That metric is meaningless now that anyone can deploy bots by the thousands with a single command.
Does Claude Code's system prompt have special sauces?
Yes, very much so.
I've been able to get Gemini flash to be nearly as good as pro with the CC prompts. 1/10 the price 1/10 the cycle time. I find waiting 30s for the next turn painful now
https://github.com/Piebald-AI/claude-code-system-prompts
One nice bonus to doing this is that you can remove the guardrail statements that take attention.
Interesting, what exactly do you need to make this work? There seem to be a lot of prompts and Gemini won't have the exact same tools I guess? What's your setup?
Yeah, you do want to massage them a bit, and I'm on some older ones before they became so split, but this is definitely the model for subagents and more tools.
Most of my custom agent stack is here, built on ADK: https://github.com/hofstadter-io/hof/tree/_next/lib/agent
Thanks for the link. Very helpful to understanding what’s going on under the hood.
Which are better and free software?
None exist yet, but that doesn't mean OpenCode is automatically good.
Didn't mean to imply OpenCode was any good... was honestly looking for a recommendation.
I kind of think that these threads are destined to fossilize quickly. Most every syllogism about LLMs from 2024 looks quaint now.
A more interesting question is whether there's really a future for running a coding agent on a non-highest setting. I haven't seen anything near "Shall I implement it? No" in quite a while.
Unless perhaps the highest-tier accounts go from $200 to $20K/mo.
Often times I'll say something like:
"Can we make the change to change the button color from red to blue?"
Literally, this is a yes or no question. But the AI will interpret this as me _wanting_ to complete that task and will go ahead and do it for me. And they'll be correct--I _do_ want the task completed! But that's not what I communicated when I literally wrote down my thoughts into a written sentence.
I wonder what the second order effects are of AIs not taking us literally is. Maybe this link??
Such miscommunication (varying levels of taking it literally) is also common with autistic and allistic people speaking with each other
I don't find that an unreasonable interpretation. Absent that paragraph of explained thought process, I could very well read it the agent's way. That's not a defect in the agent, that's linguistic ambiguity.
I mean humans communicate the same way. We don't interpret the words literally and neither does the LLM. We think about what one is trying to communicate to the other.
For example If you ask someone "can you tell me what time it is?", the literal answer is either "yes"/"no". If you ask an LLM that question it will tell you the time, because it understands that the user wants to know the time.
very fair! wild to think about though. It's both more human but also less.
I would say this behavior now no longer passes the Turing test for me--if I asked a human a question about code I wouldn't expect them to return the code changes; i would expect the yes/no answer.
It's funny because I interpret it the opposite way you do. If someone asked me that question, I'd absolutely assume they want it changed and do it.
If you work with codex a lot you’ll find it is good at taking you literally, and that that is almost never what you want.
Respect Claude Code and the output will be better. It's not your slave. Treat it as your teammate. Added benefit is that you will know it's limits, common mistakes etc, strenghts, etc, and steer it better next session. Being too vague is a problem, and most of the times being too specific doesn't help either.
Flirt with Claude Code. Go out on dates with Claude Code. Propose to Claude Code. Marry Claude Code. Have children, with Claude Code. Caress Claude Code at night. Die, by Claude Code's side.

Is this a troll comment? How could the dialogue in the OP possibly be unclear under any context?
No is a pretty clear statement
No
no
Why is this in the top of HN?
1) That's just an implementation specifics of specific LLM harness, where user switched from Plan mode to Build. The result is somewhat similar to "What will happen if you assign Build and Build+Run to the same hotkey".
2) All LLM spit out A LOT of garbage like this, check https://www.reddit.com/r/ClaudeAI/ or https://www.reddit.com/r/ChatGPT/, a lot of funny moments, but not really an interesting thing...
What else is an LLM supposed to do with this prompt? If you don’t want something done, why are you calling it? It’d be like calling an intern and saying you don’t want anything. Then why’d you call? The harness should allow you to deny changes, but the LLM has clearly been tuned for taking action for a request.
Ask if there is something else it could do? Ask if it should make changes to the plan? Reiterate that it's here to help with anything else? Tf you mean "what else is it suppose to do", it's supposed to do the opposite of what it did.
I think there is some behind the scenes prompting from claude code for plan vs build mode, you can even see the agent reference that in it's thought trace. Basically I think the system is saying "if in plan mode, continue planning and asking questions, when in build mode, start implementing the plan" and it looks to me(?) like the user switched from plan to build mode and then sent "no".
From our perspective it's very funny, from the agents perspective maybe very confusing.
I'd want two things:
First, that It didn't confuse what the user said with it's system prompt. The user never told the AI it's in build mode.
Second, any person would ask "then what do you want now?" or something. The AI must have been able to understand the intent behind a "No". We don't exactly forgive people that don't take "No" as "No"!
Because i decided that i don't want this functionality. That's it.
Seems like LLMs are fundamentally flawed as production-worthy technologies if they, when given direct orders to not do something, do the thing
for the same reason `terraform apply` asks for confirmation before running - states can conceivably change without your knowledge between planning and execution. maybe this is less likely working with Claude by yourself but never say never... clearly, not all behavior is expected :)
> What else is an LLM supposed to do with this prompt?
Maybe I saw the build plan and realized I missed something and changed my mind. Or literally a million other trivial scenarios.
What an odd question.
> What an odd question.
I don't see anything odd about this question.
What kind of response did the user expect to get from LLM after spending this request and what was the point of sending it in the first place?
Genuine questions: what do you think the request was? To build the plan? To prepare the commit? Do you never have a second thought after looking at your output, or realize you forgot something you wanted to include? Could it be that they saw "one new function", thought "boy, there should really be two... what happened?" and changed their mind?
To your original comment, it would be like calling your intern to ask them to order lunch, and them letting you know the sandwich place you asked them to order from was closed, and should they just put in an order for next Tuesday at an entirely different restaurant instead? And then that intern hearing, "no, that's not what I want" saying "well, I don't respect your 'no'" and doing it anyways.
"Do X" -> "Here are the anticipated actions (which might deviate from your explicit intent), should I implement?" -> "no, that's not actually what I want"
is a clear instruction set and a completely normal thought pattern.
My point is that I don't see any scenario in which sending a ton of input tokens (the whole past conversation) and expecting output that literally does nothing is absolutely pointless.
Like, sure, if the model were "smarter" it would probably generate something like "Okay, I won't do it.". What is the value of the response "Okay, I won't do it."? Why did you just waisted time and compute to generate it?
> Do you never have a second thought after looking at your output, or realize you forgot something you wanted to include? Could it be that they saw "one new function", thought "boy, there should really be two... what happened?" and changed their mind?
Sure, all of those are totally valid. And in each of this cases it would be better to just don't make the request at all or make the request with the correction.
> like calling your intern
LLM is not human. It can't act on it's own without you triggering it to act. Unlike the intern in your example who will be wasting time and getting frustrated if they don't receive a response from you. With model you can just abandon this "conversation" (which is really just a growing context that you send again and again with every request) forever or until you are ready to continue it. There is no situation when just adding "no" to the conversation is useful.
Why does it ask a yes-no question if it isn’t prepared to take “no” as an answer?
(Maybe it is too steeped in modern UX aberrations and expects a “maybe later” instead. /s)
> Why does it ask a yes-no question if it isn’t prepared to take “no” as an answer?
Because it doesn’t actually understand what a yes-no question is.
