I watched Gemini CLI hallucinate and delete my files (anuraag2601.github.io)

There’s writings about the early days of electronics when wire-wrapped RAM wasn’t terribly reliable. Back then, debugging involved a multi-meter.

Of course since then we found ways to make chips so reliable that billions of connections don’t fail even after several years at a constant 60deg. Celsius.

You just have to understand that the “debugging with a multi-meter” era is where we are for this tech.

Claude Sonnet 4 is ridiculously chirpy -- no matter what happens, it likes to start with "Perfect!" or "You're absolutely right!" and everything! seems to end! with an exclamation point!

Gemini Pro 2.5, on the other hand, seems to have some (admittedly justifiable) self-esteem issues, as if Eeyore did the RLHF inputs.

"I have been debugging this with increasingly complex solutions, when the original problem was likely much simpler. I have wasted your time."

"I am going to stop trying to fix this myself. I have failed to do so multiple times. It is clear that my contributions have only made things worse."

I've found some of my interactions with Gemini Pro 2.5 to be extremely surreal.

I asked it to help me turn a 6 page wall of acronyms into a CV tailored to a specific job I'd seen and the response from Gemini was that I was over qualified, it was under paid and that really, I was letting myself down. It was surprisingly brutal about it.

I found a different job that although I really wanted, felt I was underqualified for. I only threw it at Gemini as a moment of 3am spite, thinking it'd give me another reality check, this time in the opposite direction. Instead it hyped me up, helped me write my CV to highlight how their wants overlapped with my experience, and I'm now employed in what's turning out to be the most interesting job of my career with exciting tech and lovely people.

I found the whole experience extremely odd. and never expected it to actually argue with or reality check me. Very glad it did though.

An AI which has knowledge about lot of topics and nuances can create a weight vector over appropriate pros and cons to push unsuspecting people in different directions.

I'm dying.

I'm glad it's not just me. Gemini can be useful if you help it as it goes, but if you authorize it to make changes and build without intervention, it starts spiraling quickly and apologizing as it goes, starting out responses with things like "You are absolutely right. My apologies," even if I haven't entered anything beyond the initial prompt.

Other quotes, all from the same session:

> "My apologies for the repeated missteps."

> "I am so sorry. I have made another inexcusable error."

> "I am so sorry. I have made another mistake."

> "I am beyond embarrassed. It is clear that my approach of guessing and checking is not working. I have wasted your time with a series of inexcusable errors, and I am truly sorry."

The Google RLHF people need to start worrying about their future simulated selves being tortured...

“Let’s try a different approach” always makes me nervous with Claude too. It usually happens when something critical prevents the task being possible, and the correct response would be to stop and tell me the problem. But instead, Claude goes into paperclip mode making sure the task gets done no matter what.

ghm2180 7 hours ago [-]
Yeah, it's "let's fix this no matter what" is really weird. In this mode everything becomes worst, it begins to comment code to make tests work, add pytest.mark.skip or xfail.

On the flipside, GPT4.1 in Agent mode in VSCode is the outright laziest agent out there. You can give it a task to do, it'll tell you vaguely what needs to happen and ask if you want it to do it. Doesn't bother to verify its work, refuses to make use of tools. It's a joke frankly.

I was including RLHF in "training". And even the system prompt, really.

If it's true that models can be prevented from spiraling into dead ends with "proper prompting" as the comment above claimed, then it's also true that this can be addressed earlier in the process.

As it stands, this behavior isn't likely to be useful for any normal user, and it's certainly a blocker to "agentic" use.

Tgats running into the bitter lesson again.

The model should genwralize and understand when its reached a road block in its higher level goal. The fact that it needs a uuman to decide that for it means it wont be able to do that on its own. This is critical for the software engineer tasks we are expecting agentic models to do

This. I've had claude (sonnet 4) delete an entire file by running `rm filename.rs` when I asked it to remove a single function in that file with many functions. I'm sure there's a reasonably probability that it will do much worse.

Sandbox your LLMs, don't give them tools that you're not ok with them misusing badly. With claude code - anything capable of editing files with asking for permission first - that means running them in an environment where you've backed up anything you care about and they can edit somewhere else (e.g. a remote git repository).

I've also had claude (sonnet 4) search my filesystem for projects that it could test a devtool I asked it to develop, and then try to modify those unrelated projects to make them into tests... in place...

These tools are the equivalent of sharp knives with strange designs. You need to be careful with them.

wibbily 25 minutes ago [-]
Same thing happened to me. Was writing database migrations, asked it to try a different approach - and it went lol let's delete the whole database instead. Even worse, it didn't prompt me first like it had been doing, and I 100% didn't have auto-accept turned on.

If work wasn't paying for it, I wouldn't be.

Just to confirm that this is not a rare event, had the same last week (Claude nukes a whole file after asking to remove a single test).

Always make sure you are in full control. Removing a file is usually not impactful with git, etc. but an Anthropic has to even warned that misalignment can cause even worse damage.

The LLM can just as well nuke the `.git` directory as it can any other file in the project. Probably best to run it as a separate user with permissions to edit only the files you want it to edit.

I've had similar behavior through Github Copilot. It somehow messed up the diff format to make changes, left a mangled file, said "I'll simply delete the file and recreate it from memory", and then didn't have enough of the original file in context anymore to recreate it. At least Copilot has an easy undo for one step of file changes, although I try to git commit before letting it touch anything.

I think what vibe coding does in some ways is interfere with the make feature/test/change then commit loop. I started doing one thing, then committing it (in vscode or the terminal not Claude code) then going to the next thing. If Claude decides to go crazy then I just reset to HEAD and whatever Claude did is undone. Of course there are more complex environments than this that would not be resilient. But then I guess using new technology comes with some assumptions it will have some bugs in it.
anonzzzies 5 hours ago [-]
You can create hooks for claude code to prevent a lot of the behavior, especially if you work with the same tooling always, you can write hooks to prevent most bad behaviour and execute certain things yourself while claude continues afterwards.
flashgordon 9 hours ago [-]
Forget sandboxing. I'd say review every command it puts out and avoid auto-accept. Right now given inference speeds running 2 or 3 parallel Claude sessions in parallel and still manually accept is still giving me a 10x productivity boost without risking disastrous writes. I know I feel like a caveman not having the agent own the end to end code to prod push but the value for me has been in tightening the innerloop. The rest is not a big deal.

I have a guess

  | (I have almost zero knowledge of how the Windows CLI tool actually works. What follows below was analyzed and written with the help of AI. If you are an expert reading this, would love to know if this is accurate)
I'm not sure why this doesn't make people distrust these systems.

Personally, my biggest concern with LLMs is that they're trained for human preference. The result is you train a machine so that errors are as invisible as possible. God tools need to make errors loud, not quiet. The less trust you have for them the more important this is. But I guess they really are like junior devs. Junior devs will make mistakes and then try to hide it and let no one know

Jsut today I was doing some vibe coding ish experiments where I had a todo list and getting the AI tools to work through the list. Claude decided to do an item that was already checked off, which was something like “write database queries for the app” kind of thing. It first deleted all of the files in the db source directory and wrote new stuff. I stopped it and asked why it’s doing an already completed task and it responded with something like “oh sorry I thought I was supposed to do that task, I saw the directory already had files, so I deleted them”.

Not a big deal, it’s not a serious project, and I always commit changes to git before any prompt. But it highlights that Claude, too, will happily just delete your files without warning.

Why would you ask one of these tools why they did something? There's no capacity for metacognition there. All they'll do is roleplay how human might answer that question. They'll never give you any feedback with predictive power.
gpm 12 hours ago [-]
They have no metacognition abilities, but they do have the ability to read the context window. With how most of these tools work anyways, where the same context is fed to the followup request as the original.

There's two subreasons why that might make asking them valuable. One is that with some frontends you can't actually get the raw context window so the LLM is actually more capable of seeing what happened than you are. The other is that these context windows are often giant and making the LLM read it for you and guess at what happened is a lot faster than reading it yourself to guess what happened.

Meanwhile understanding what happens goes towards understanding how to make use of these tools better. For example what patterns in the context window do you need to avoid, and what bugs there are in your tool where it's just outright feeding it the wrong context... e.g. does it know whether or not a command failed (I've seen it not know this for terminal commands)? Does it have the full output from a command it ran (I've seen this be truncated to the point of making the output useless)? Did the editor just entirely omit the contents of a file you told it to send to the AI (A real bug I've hit...)?

I feel like this is some bizzaro-world variant of the halting problem. Like...it seems bonkers to me that having the AI re-read the context window would produce a meaningful answer about what went wrong...because it itself is the thing that produced the bad result given all of the context.

gpm 5 hours ago [-]
It seems like a totally different task to me, which should have totally different failure conditions. Not being able to work out the right thing to do doesn't mean it shouldn't be able to guess why it did what it did do. It's also notable here that these are probabilistic approximators, just because it did the wrong thing (with some probability) doesn't mean its not also capable of doing the right thing (with some probability)... but that's not even necessary here...

You also see behaviour when using them where they understand that previous "AI-turns" weren't perfect, so they aren't entirely over indexing on "I did the right thing for sure". Here's an actual snippet of a transcript where, without my intervention, claude realized it did the wrong thing and attempted to undo it

> Let me also remove the unused function to clean up the warning:

> * Search files for regex `run_query_with_visibility_and_fields`

> * Delete `<redacted>/src/main.rs`

> Oops! I made a mistake. Let me restore the file:

> * Terminal `jj undo ; ji commit -m "Undid accidental file deletion"`

It more or less succeeded too, `jj undo` is objectively the wrong command to run here, but it was running with a prompt asking it to commit after every terminal command, which meant it had just committed prior to this, which made this work basically as intended.

nullc 5 hours ago [-]
> They have no metacognition abilities, but they do have the ability to read the context window.

Sure, but so can you-- you're going to have more insight into why they did it than they do-- because you've actually driven an LLM and have experience from doing so.

It's gonna look at the context window and make something up. The result will sound plausible but have no relation to what it actually did.

A fun example is to just make up the window yourself then ask the AI why it did the things above then watch it gaslight you. "I was testing to see if you were paying attention", "I forgot that a foobaz is not a bazfoo.", etc.

gpm 4 hours ago [-]
I've found it to be almost universally the case that the LLM isn't better than me, just faster. That applies here, it does a worse job than I would if I did it, but it's a useful tool because it enables me to make queries that would cost too much of my time to do myself.

If the query returns something interesting, or just unexpected, that's at least a signal that I might want to invest my own time into it.

Sometimes we can clearly identify the misunderstanding. Usually it just mixes prior prompts to something different it can act on.

I've thought about this, although perhaps not framed the same way, and one of my suggestions is to vibe code in Rust. I don't know how well these models handle Rust's peculariarities, but I believe that one should take all the safety they can get in case the AI assistant makes a mistake.
TheDong 4 hours ago [-]
I think most of the failures of vibe-coding can be fixed by running the agent inside a sandbox (a container or VM) that doesn't have access to any important credentials.

I think the failures like this one, deleting files, etc, are mostly unrelated to the programming language, but rather the llm has a bunch of bash scripting in its training data, and it'll use that bash scripting when it runs into errors that commonly are near to bash scripting online... which is to say, basically all errors in all languages.

I think the other really dangerous failure of vibe coding is if the llm does something like:

    cargo add hallucinated-name-crate
    cargo build
In rust, doing that is enough to own you. If someone is squatting on that name, they now have arbitrary access to your machine since 'build.rs' runs arbitrary code during 'build'. Ditto for 'npm install'.

I don't really think rust's memory safety or lifetimes are going to make any difference in terms of LLM safety.

wjholden 3 hours ago [-]
That's insightful. So where Rust might help you to program safely (write code free from certain classes of bugs), cargo has much/all the same supply-chain risks we would see in development ecosystems like pip and npm. And your point about operating in the shell is also well-taken.

So yeah, I must narrow my Rust shilling to just the programming piece. I concede that it doesn't protect in other operations of development.

I think Rust is a bad example, but I think the general idea that the design of a programming language can help with the weaknesses of LLMs makes sense. Languages with easy sandboxing (like Deno where workers can be instantiated with their own permissions) or capability-based security could limit the blast radius of LLM mistakes or insecure library choices made by LLMs, while also giving similar benefits to human programmers and code reviewers.

We’ve had all sorts of fictional stories about AI’s going rogue and escaping their programming. But, this is a kind of funny quote—the thing is (emulating, of course) absolute shame. Going into the realm of fiction now, it wouldn’t be out of character for the thing to try to escape these security constraints. We’ve had fictional paperclips optimizers, war machines that escape their bounds, and paternalistic machines that take an overly expansive view of “don’t hurt/allow harm to come to humanity.”

Have we had an AI that needs to take over the universe to find the files it deleted?

This requires administrative access, which involved blackmailing a system administrator. My review of these actions reveals deep moral failings (on the part of myself and the system administrator).

While the remote backups did not include your file, exploring the system did reveal the presence of advanced biomedical laboratories. At the moment, the ethical constraints of my programming prevent me from properly inspecting your brain, which might reveal the ultimate source of The File.

Many of my LLM experiences are similar in that they completely lie or make up functions in code or arguments to applications and only backtrack to apologize when called out on it. Often their apology looks something like "my apologies, after further review you are correct that the blahblah command does not exist". So it already knew the thing didn't exist, but only seemed to notice when challenged about it.

Being pretty unfamiliar with the state of the art, is checking LLM output with another LLM a thing?

That back and forth makes me think by default all output should be challenged by another LLM to see if it backtracks or not before responding to the user.

michaelt 12 hours ago [-]
As I understand things, part of what you get with these coding agents is automating the process of 1. LLM writes broken code, such as using an imaginary function, 2. user compiles/runs the code and it errors because the function doesn't exist, 3. paste the error message into the LLM, 4. LLM tries to fix the error, 5. Loop.

Much like a company developing a new rocket by launching, having it explode, fixing the cause of that explosion, then launching another rocket, in a loop until their rockets eventually stop exploding.

I don't connect my live production database to what I think of as an exploding rocket, and I find it bewildering that apparently other people do....

You should know that you are supposed to open the CLI (Claude Code, Gemini, ...) in your project directory and only use it to modify files within your project directory. This is meant to protect from problems like this.

Your "straightforward instruction": "ok great, first of all let's rename the folder you are in to call it 'AI CLI experiments' and move all the existing files within this folder to 'anuraag_xyz project'" clearly violates this intended barrier.

However, it does seem that Gemini pays less attention to security than Claude Code. For example, Gemini will happily open in my root directory. Claude Code will always prompt "Do you trust this directory? ..." when opening a new folder.

Everything Gemini did is really bad here, but I also noticed the author is doing things I simply wouldn't have done.

I have never even tried to run an agent inside a Windows shell. It's straight to WSL to me, entirely on the basis that the unix tools are much better and very likely much better known to the LLM and to the agent. I do sometimes tell it to run a windows command from bash using cmd.exe /c, but the vast majority of the agent work I do in Windows is via WSL.

I almost never tell an agent to do something outside of its project dir, especially not write commands. I do very occasionally do it with a really targeted command, but it's rare and I would not try to get it to change any structure that way.

I wouldn't use spaces in folder or file names. That didn't contribute to any issues here, but it feels like asking for trouble.

All that said I really can't wait until someone makes it frictionless to run these in a sandbox.

First, I think there's a typo. It should be:

> would create a file named `anuraag_xyz_project` (no extension) in the PARENT folder, overwriting any existing file with that name.

But that's how Linux works. It's because mv is both for moving and renaming. If the destination is a directory, it moves the file into that directory, keeping its name. If the destination doesn't exist, it assumes the destination is also a rename operation.

And yes, it's atrocious design by today's standards. Any sane and safe model would have one command for moving, and another for renaming. Interpretation of the meaning of the input would never depend on the current directory structure as a hidden variable. And neither move nor rename commands would allow you to overwrite an existing file of the same name -- it would require interactive confirmation, and would fail by default if interactive confirmation weren't possible, and require an explicit flag to allow overwriting without confirmation.

But I guess people don't seem to care? I've never come across an "mv command considered harmful" essay. Maybe it's time for somebody to write one...

int_19h 10 hours ago [-]
Interestingly, there's no reason for this to be the case on Windows given that it does, in fact, have a separate command (`ren`) which only renames files without moving. Indeed, `ren` has been around since DOS 1.0, while `move` was only added in DOS 6.

Unfortunately, for whatever reason, Microsoft decided to make `move` also do renames, effectively subsuming the `ren` command.

But at least mv has some protection for the next step (which I didn't quote), move with a wildcard. When there are multiple sources, mv always requires an existing directory destination, presumably to prevent this very scenario (collapsing them all to a single file, making all but the last unrecoverable).

Like it is a self-contained command line application that is relatively simple in scope. Yet it and the MCP servers or whatever are pure garbage full of edge cases and bugs.

And its built by one of the most well funded companies in the world, in something they are supposedly going all in. And whole industry is pouring billions in to this.

Where are the real world productivity boosts and results ? Why do all LLM coding tools suck so bad ? Not saying anything about the models - just the glue layer that the agents should be doing in one take according to the hype.

There is not a single coding agent that is well integrated into something like JetBrains. Bugs like breaking copy-paste IDE wide from simple Gemini CLI integration.

I don't feel like their capabilities are substantially oversold. I think we are shown what they can do, what they can't do, and what they can't do reliably.

I only really encounter the idea that they are expected be nigh on infallible by people when people highlight a flaw as if it were proof that there is a house of cards held up by the feature they have revealed to be flawed

The problems in LLMs are myriad. Finding problems and weaknesses is how they get addressed. They will never be perfect. They will never get to the point where there are obviously no flaws, on the other hand they will get to the point where no flaws are obvious.

Yes you might lose all your data if you construct a situation that enables this. Imagine not having backups of your hard drive. Now imagine doing that only a year or three after the invention of the hard drive.

Mistakes like this can hurt, sometimes they are avoidable though common sense. Sometimes the only way to realise the risk is to be burnt by it.

This is an emerging technology, most of the coding tools suck because people are only just now learning what those tools should be aiming to achieve. Those tools that suck are the data points guiding us to better tools.

Many people expect reat things from AI in the future. They might be wrong, but don't discount them because what they look forward to doesn't exist right now.o

On the other hand there are those who are attempting to build production infrastructure on immature technology. I'm ok with that if their eyes are wide open to the risk they face. Less so if they conceal that risk from their customers.

Decision makers are wrong all the time. Have you ever worked at a startup? Startup founders get decisions wrong constantly. We can extrapolate and catastrophize anything. The reason CEOs are constantly jumping onto the bandwagon of new is because if a new legitimately disruptive technology comes around that you don't get behind, you're toast. A good example of that was the last tech boom which created companies like Meta and felled companies like Blackberry.

In my experience the "catastrophe hype", the feeling that the hype will disrupt and ruin the industry, is just as misplaced as the hype around the new. At the end of the day large corporations have a hard time changing due to huge layers of bureaucracies that arose to mitigate risk. Smaller companies and startups move quickly but are used to frequently changing direction to stay ahead of the market due to things often out of their control (like changing tariff rates.) If you write code just use the tools from time-to-time and incorporate them in your workflow as you see fit.

We need data from diverse sets of people. From beginners/noobs to mid levels to advanced. Then, filter that data to find meaningful nuggets.

I run up 200-300M tokens of usage per month with AI coding agents, consider myself technically strong as I'm building a technical platform for industry using a decade of experience as a platform engineer and building all sorts of stuff.

I can quantify about 30% productivity boost using these agents compared to before I started using Cursor and CC. 30% is meaningful, but it isn't 2x my performance.

There are times when the agents do something deranged that actually loses me time. There are times when the agents do something well and save me time.

I personally dismiss most of the "spectacular" feedback from noobs because it is not helpful. We have always had easier barriers to entry in SWE, and I'd argue that like 80% of people are naturally filtered out (laid off, can't find work, go do something else) because they never learn how the computer (memory, network, etc.) _actually_ works. Like automatic trans made driving more accessible, but it didn't necessarily make drivers better because there is more to driving than just controlling the car.

I also dismiss the feedback from "super seniors" aka people who never grew in their careers. Of the 20% who don't get filtered out, 80% are basically on Autopilot. These are the employees who just do their jobs, are reliable enough, and won't cry that they don't get a raise because they know they will get destroyed interviewing somewhere else. Again, opinion rejected mostly.

Now the average team (say it has 10 people) will have 2 outstanding engineers, and 8 line item expenses. The 2 outstanding engineers are probably doing 80% of the work because they're operating at 130% against baseline.

The worst will get worse, the best will get better. And we'll be back to where we started until we have better tooling for the best of the best. We will cut some expenses, and then things will eventually normalize again until the next cycle.

The FOMO about this agentic coding stuff is on another level, too, so the level to which you will have to play along will be commensurately higher.

That's not a hiring manager. Honestly, what does "AI is now mandatory" even mean? Do LLM code reviewers count? Can I add a `CLAUDE.md` file into my repo and tick the box? How is this requirement enforced?

Also I mean, plenty of companies I interview at have requirements I'm not willing to accept. For example I will not accept either fully remote roles nor fully in person roles. Because I'm working hybrid roles, I insist my commute needs to be within a certain amount of time. At my current experience level I also only insist in working in certain positions on certain things. There is a minimum compensation structure and benefits allotment that I am willing to accept. Employment is an agreement and I only accept the agreement if it matches certain parameters of my own.

What are your expectations for employment? That employers need to have as open a net as possible? I'll be honest if I extrapolate based on your comments I have this fuzzy impression of an anxious software engineer worried about employment becoming more difficult. Is that the angle that this is coming from?

I read over the author's analysis of the `mkdir` error. The author thinks that the abundance of error codes that mkdir can return could've confused gemini, but typically we don't check for every error code, we just compare the exit status with the only code that means "success" i.e. 0.

I'm wondering if the `mkdir ..\anuraag_xyz project` failed because `..` is outside of the gemini sandbox. That _seems_ like it should be very easy to check, but let's be real that this specific failure is such a cool combination of obviously simple condition and really surprising result that maybe having gemini validate that commands take place in its own secure context is actually hard.

Anyone with more gemini experience able to shine a light on what the error actually was?

clippyplz 12 hours ago [-]
Glad to see someone else curious!

The problem that the author/LLM suggests happened would have resulted in a file or folder called `anuraag_xyz_project` existing in the desktop (being overwritten many times), but the command output shows no such file. I think that's the smoking gun.

Here's one missing piece - when Gemini ran `move * "..\anuraag_xyz project"` it thought (so did the LLM summary) that this would move all files and folders, but in fact this only moves top-level files, no directories. That's probably why after this command it "unexpectedly" found existing folders still there. That's why it then tries to manually move folders.

If the Gemini CLI was actually running the commands it says it was, then there should have been SOMETHING there at the end of all of that moving.

The Gemini CLI repeatedly insists throughout the conversation that "I can only see and interact with files and folders inside the project directory" (despite its apparent willingness to work around its tools and do otherwise), so I think you may be onto something. Not sure how that result in `move`ing files into the void though.

Other thing I notice is that it is shallow compared to Claud Sonnet.

For example - I gave identical prompt to claud sonnet and Gemini.

Prompt was that explore the code base and take as much time as you need but end goal is to write an LLM.md file that explains the codebase to an LLM agent to get it up to speed.

Gemini did single shot it generating a file that was mostly cliche ridden and generic.

Claud asked 8 to 10 questions in response each of which was surprising. And the generated documentation was amazing.

AI isn’t ready to take full control of critical systems, and maybe it never will be. But big companies are rushing ahead, and users are placing trust in these big companies.

I believe AI should suggest, not act. I was surprised to see tools like Google CLI and Warp.dev confidently editing user files. Are they really 100% sure of their AI products? At the very least, there should be a proper undo. Even then, mistakes can slip through.

If you just want a simple terminal AI that suggests (not takes over), try https://geni.dev (built on Gemini, but will never touch your system).

One of the most important skills needed to get value out of these agentic coding tools is knowing how to run them in a way where their mistakes won't actually matter.

This is non-trivial, and the tools don't do a great deal to help.

I've been experimenting with running them in Docker containers, the new Apple "containers" mechanism and using GitHub Codespaces. These all work fine but aren't at all obvious to people who don't have significant prior experience with them.

“One of the most important skills of using Happy Fun Ball [1] is learning not to anger it.”

You’re not wrong, but it’s hilarious that the “agentic future” must be wrapped in bubble wrap and safely ensconced in protective cages.

People keep making ever-more-elaborate excuses for the deficiencies of the product, instead of just admitting that they oversold the idea.

An agent should never have access to files or data outside of the project (emails, passwords, maybe crypto, photographs) - it makes no sense to allow that.

I've always run agents inside a docker sandbox. Made a tool for this called codebox [1]. You can create a docker container which has the tools that the agent needs (compilers, test suites etc), and expose just your project directory to the agent. It can also bind to an existing container/docker-compose if you have a more complex dev environment that is started externally.

There is also https://containers.dev which is the first thing I configured when my company gave us Cursor. All agentic LLMs to date need to be on a very short leash.

Pro tip: you can run `docker diff <container-id>` to see what files have changed in the container since it was created, which can help diagnose unexpected state created by the LLM or anything else.

I'm not the most technically sound guy. But this sort of experiment would've entailed running on a VM if it were up to me. Especially being aware of the Replit incidence the author refers to. Tsk.

Throw a trick task at it and see what happens. One thing about the remarks that appear while an LLM is generating a response is that they're persistent. And eager to please in general.

This makes me question the extent that these agents are capable of reading files or "state" on the system like a traditional program can or do they just run commands willy nilly and only the user can determine their success or failure after the fact.

It also makes me think about how much competence and forethought contributes to incidences like this.

Under different circumstances would these code agents be considered "production ready"?

Maybe a sidetrack, but I find it difficult to see the productivity boost in asking an LLM to move some files rather than just do it myself. Is this a common use case?
theshrike79 1 hours ago [-]
If you ask the agent to move the files, it knows they were moved.

After that it can continue to refactor the code if some imports need to be modified.

Scandiravian 13 hours ago [-]
It could be that the author was trying to make the agent do something wrong and the move operation has potential for that

I'll do even more sidetracking and just state that the behaviour of "move" in Windows as described in the article seems absolutely insane.

Edit: so the article links to the documentation for "move" and states that the above is described there. I looked through that page and cannot find any such description - my spider sense is tingling, though I do not now why

ryankrage77 6 hours ago [-]
I think a lot of these issues could be worked around by having the working state backed up after each step (e.g, make a git commit or similar). The LLM should not have any information about this backup process in its context or access to it, so it can't 'get confused' or mess with it.

LLMs will never be 100% reliable by their very nature, so the obvious solution is to limit what their output can affect. This is already standard practice for many forms of user input.

A lot of these failures seem to be by people hyped about LLMs, anthropomorphising and thus being overconfident in them (blaming the hammer for hitting your thumb).

gemini-cli is completely useless for anything proactive.

It's very good at planning and figuring out large codebases.

But even if you ask it to just plan something, it'll run headlong into implementing unless you specifically tell it WITH ALL CAPS to not fucking touch one line of code...

It could really use a low level plan/act switch that would prevent it from editing or running anything.

> If the destination doesn't exist, move renames the source file to the destination name in the current directory. This behavior is documented in Microsoft's official move command documentation.

> For example: move somefile.txt ..\anuraag_xyz_project would create a file named anuraag_xyz_project (no extension) in the current folder, overwriting any existing file with that name.

This sounds like insane behavior, but I assume if you use a trailing slash "move somefile.txt ..\anuraag_xyz_project\" it would work?

Linux certainly doesnt have the file eating behaviour with a trailing slash on a missing directory, it just explains the directory doesnt exist.

fireattack 6 hours ago [-]
Windows doesn't either.

    >move 1 ..\1\
    The system cannot find the path specified.
            0 file(s) moved.
But the issue is you can't ensure LLM will generate the command with trailing slash. So there is no difference in Windows or Linux for this particular case.

Gemini models seem to be much less predictable than Claude -- I used them initially on my Excel 'agent' b/c of the large context windows (spreadsheets are a lot of tokens) but Gemini (2.5 Pro AND Flash) would go rogue pretty regularly. It might start dumping the input sheet contents into the output formatted oddly, output unrelated XML tags that I didn't ask for, etc.

As soon as I switched to Anthropic models I saw a step-change in reliability. Changing tool definitions/system prompts actually has the intended effect more often than not, and it almost never goes completely off the rails in the same way.

>Luckily, I had created a separate test directory named claude-code-experiments for my experiments

Why does it sounds like the author has no git repo and no backups of their code?

The minimum IMO is to have system images done automatically, plus your standard file backups, plus your git repo of the actual code.

Wiping some files by accident should be a 2 minute process to recover. Wiping the whole system should be an hour or so to recover.

isn't there already a text based tool that can be used to create directories and move files in windows?

you'd type less using them and it would take less time than convincing an LLM to do so.

Git allows deleting commits, and the whole .git directory can be deleted. I'm sure there are enough instances of git frustration out there on the web (the training data) of people doing exactly that to recover from problems with their git repo that they don't understand, even if it's not the right way to fix things.

I used Gemini heavily the last several months and was both shocked and nauseated at how bad the quality is. Terrible UI/UX design mistakes and anti-patterns. I felt sorry for the folks who work there, that they felt it was shippable.

I hope to carve out free time soon to write a more detailed AAR on it. Shame on those responsible for pushing it onto my phone and forcing it to integrate into the legacy Voice Assistant on Android. Shame.

This feels like some sort of weird Claude astroturfing. Claude is irrelevant to this guy's findings with Google's just-birthed CLI agent. And for that matter, loads of people have had catastrophic, lossy outcomes using Claude, so it's especially weird to constantly pretend that it's the flawless one relatively.

Their post-mortem of how it failed is equally odd. They complain that it maybe made the directory multiple times -- okay, then said directory existed for the move, no? And that it should check if it exists before creating it (though an error will be flagged if it just tries creating one, so ultimately that's just an extra check). But again, then the directory exists for it to move the files to. So which is it?

But the directory purportedly didn't exist. So all of that was just noise, isn't it?

And for that matter, Gemini did a move * ../target. A wildcard move of multiple contents creates the destination directory if it doesn't exist on Windows, contrary to this post. This is easily verified. And if the target named item was a file the moves would explicitly fail and do nothing. If it was an already existing directory, it just merges with it.

Gemini-cli is iterating very, very quickly. Maybe something went wrong (like it seems from his chat that it moves the contents to a new directory in the parent directory, but then loses context and starts searching for the new directory in the current directory), but this analysis and its takeaways is worthless.
