Sorry folks, this is a rollout artifact, we needed a way to turn this off remotely via feature flags if it broke something, and with telemetry off you don't get those. It's already been fixed as part of v2.1.281 releasing today.

The mod is source available here: https://github.com/anthropics/claude-code/tree/main/mods/age...

Apologies again folks, this was a fully human error on my part - I should've found a better way to launch with a kill-switch.

mpoteat 5 hours ago

The AGENTS.md support was implemented via our new extensibility system for CC, called Mods, which is launching soon-ish. A mod is a plugin with a new type of hook, which we call a function hook.

If folks play around with it, I would love feedback on the relevant issue: https://github.com/anthropics/claude-code/issues/91870

Mods allow quite a bit more customizability and control. I really believe in the idea.

    The only difference between CLAUDE.md and AGENTS.md is the filename. Do you really need a whole plugin system to support that use case? Feels like this could have been a one line change.

    • oblio 5 hours ago

      One line change? Pffft. That means you're still looking at the code, you're behind the times.

      I don't think this is a reasonable assumption. The document format in CLAUDE.md is whatever Anthropic specifies, where AGENTS.md is a common ground format that is expected to be supported by any agent, be it from Anthropic or not.

      https://agents.md/

      You might argue that differences are small or negligible, but that is just an expectation.

      • BowBun 5 hours ago

        I think you're giving these files too much credit. There are no specs, they are freeform text. In this sense they are the same. The expectation of what could be in it by each vendor means nothing unless it's enforced.

      • ljm 5 hours ago

        It's not a format though is it? it's literally just an extension to the system prompt in plain markdown.

        There is no rhyme or reason to the structure of this file, just like with most things in AI. It's best effort human language.

    • pdpi 4 hours ago

      The plugin system itself was probably already in the making, and they just chose to implement this tiny feature as a plugin to try it out.

      As for the only difference being the file name, that's an untested assumption. Up until now, Claude hadn't supported AGENTS.md, and it's a simple application of Hyrum's Law that somebody, somewhere, was taking advantage of that to give one set of instructions to Claude, and a different set of instructions to some other provider. The correct behaviour in the presence of both files is not obvious, either.

      Having a kill switch for the change is a perfectly reasonable safety measure in case something goes horribly wrong.

      • redox99 4 hours ago

        That line of thought is the reason why everything gets so overengineered.

        Read CLAUDE.md if it doesn't exist read AGENTS.md you don't need to overthink it so much.

        • arcfour 4 hours ago

          This line of thinking is something you will quickly be disabused of once you try supporting software that hundreds of millions of people use.

          • lunar_mycroft 4 hours ago

            How, exactly, would the proposed solution (combined with a setting to disable it) break, and how would implementing it the way Anthropic did address that? Be specific.

            • arcfour 4 hours ago

              Some people might have a different CLAUDE.md and AGENTS.md because they use Claude to do one thing and $other_agent to do another thing. Or because Claude does XYZ by default, and other agents do ABC, and they want to give the correct guidance to both.

              This is, to me, a completely reasonable and believable use case that could break if you implement this fix without "overengineering" it.

              A setting to disable what? Be specific. See? Not so simple...

                How exactly do these two conflict? If you have both, nothing changes.

                • arcfour 3 hours ago

                  Which order do you prefer them in? Since CLAUDE.md is no longer necessary, but was for so long, what happens when users only update AGENTS.md going forward while keeping a stale, unchanged CLAUDE.md around?

                  We're talking about changing default behaviors here in ways that can be surprising to users. It's reasonable to try and accommodate existing setups, future setups, and - yes - careless users.

                  • scottyah 2 hours ago

                    At some point, the catering is not worth the sacrifices and future gotchas you're going to embed in the code.

                  • bakugo 1 hour ago

                    There's no surprising behaviors in that situation. Someone who is aware of the change would most likely delete CLAUDE.md. Someone who is unaware of the change would assume CLAUDE.md is still the one being read by CC, which would hold true.

                you're really over thinking this, and i'm wondering if you're risking pulling something stretching like that to pick this up shilling for Anthropic.

                • arcfour 3 hours ago

                  Is accusing someone of "shilling for Anthropic" for suggesting that a bug fix might not be so simple really the level of discourse HN has devolved to now? Is it the kind of HN you want?

                  • dylan604 2 hours ago

                    Is the level of HN discourse suggesting that having a large number of users worth of never making simple changes something you want? This isn't a move fast break things suggestion, this is a rational common sense suggestion. Instead, you're pushing an overly complex way of implementing something that would allow for all sorts of unknowns. Earlier comments suggesting this new mods concept was being worked on giving the dev a new 20lb sledge hammer so the CLAUDE/AGENTS situation suddenly got beat on like it was a railroad spike when it just needed a smaller hammer since it was only a finishing nail.

                    • cgriswald 2 hours ago

                      This conversation comes down to people saying “Why don’t you just…” to Anthropic. Anthropic has the most information and made the choice they made. That choice may have been over-engineering, an appropriate choice or both. Discussing that choice could be interesting and it could especially be informative to people without much experience. Speculating on that could lead to an interesting conversation—especially WRT how people are actually using the current status quo—but imagination seems to be lacking here.

                      Instead we get the implicated assertion that users’ existing workflows shouldn’t matter to Anthropic and accusations that someone you don’t agree with is a shill. When called on that you avoided the question.

                      To answer your question, although it wasn’t directed at me: YES. I want people to be able to discuss that exact issue even if it isn’t personally interesting to me.

              • lunar_mycroft 4 hours ago

                First, GP's proposal already addresses that. If both are present, CLAUDE.md would be used. Second, that is solved with a settings toggle. Read a boolean from .claude/settings.json and disable the new behavior if it's true (or false, depending on what you want to name the setting). third, you skipped the second part of my question: "how would implementing it the way Anthropic did address that?" Implementing the same behavior through multiple layers of abstraction and an order of magnitude more code doesn't solve the issue you mentioned.

                Bonus forth point: why is this critical to solve for claude code, but not for all the other harnesses which have all converged on AGENTS.md for this purpose?

                • arcfour 3 hours ago

                  Okay, so we agree that this fix isn't quite as simple as it sounds then, yes? We've just had 3+ paragraphs of discussion around potential edge cases and additional considerations beyond "read one of two files."

                  • lunar_mycroft 3 hours ago

                    We've had a long discussion only because you refuse to admit that a very simple solution would work (despite completely failing to show how it wouldn't). The problem is that your opinion is not in fact proof that you're right.

                    • arcfour 2 hours ago

                      I see, well I'm not particularly concerned with being right on this topic (call it a difference of opinion or matter of taste), so I wish you a pleasant day.

          • dylan604 4 hours ago

            I've never heard of the 'move fast, break things' mentality ever giving a damn about number of users. If so, no changes would ever be made. The great thing about having millions of users is QA can be eliminated entirely as you'll start hearing about issues from the users directly.

          • amluto 4 hours ago

          • dotancohen 3 hours ago

            Bash does this well, reading only the first of half a dozen config file locations it searches. And if the user needs it to read from an additional location, just add a source line to that location.

        > Having a kill switch for the change is a perfectly reasonable safety measure in case something goes horribly wrong.

        What, exactly, is going to go horribly wrong here ...? The worst case you're proposing is that an Anthropic model acts on AGENTS.md rather than CLAUDE.md. It's not going to be the end of the world; at worst it'll be `git reset --hard HEAD` time. But this wouldn't happen, because:

        > The correct behaviour in the presence of both files is not obvious, either.

        It seems extremely obvious to me: the non-breaking change is the right change here. If both exist, Anthropic models continue to use CLAUDE.md and ignore AGENTS.md. This is not rocket science. Why are we overthinking this?

        • vikramkr 4 hours ago

          Because when you have tons of users ainor fuckuo is a big fuckup and also it's really common to have both claude.md and agents.md and use @ syntax (which lets you reference markdown files when using Claude code, but not other harnesses) so you Claude md looks like

          ```md @AGENTS.md

          [Claude specific stuff]

          ```

          And then what happens if someone now puts @syntax in their agents.md triggering a loop etc. It's all vibe coded - including code from days with dumber models - there's gonna be all sorts of dragons under the hood

        • hamburglar 3 hours ago

          > What, exactly, is going to go horribly wrong here ...?

          Operating anything at scale teaches you that the universe of “things that can go horribly wrong” has a much better imagination than you. That goes quadruple with complex and squishy reasoning models.

          I’ve seen a couple of really good examples of what can go wrong in this subthread, the most straightforward of which is that abruptly changing a fundamental behavior can break existing use cases.

        > somebody, somewhere, was taking advantage of that to give one set of instructions to Claude, and a different set of instructions to some other provider.

        I'm this person, I am actively doing this! I have some instructions which the Claude models need and OpenAI models will do by themselves. If the OpenAI models see the Claude instructions, they will go way overboard in a way I don't want.

        Mind, the change does not affect me at all, because when both instructions are present Claude continues to read CLAUDE.md and Codex continues to read AGENTS.md. But if Claude started preferring AGENTS.md, that would be mildly annoying.

        • californical 3 hours ago

          • everforward 3 hours ago

            I did this at one point with Jinja templates.

            I wrote an agent launcher sort of bash script. Pass in the command to start the agent, the script checks if there’s a Jinja file in a special directory matching that name, and builds it to AGENTS.md. Then it launches the agent.

            I was trying to use it as a sort of janky RAG. I had a bunch of snippets (one for DB architecture, one for how load balancing works, etc), and my Jinja files were mostly a list of snippets to pull in. Voila, a bunch of agents that share little pieces of info but have a single source of truth.

            I never got a ton of value tbh, it was very good at just grepping the snippets.

      • bakugo 4 hours ago

        This "tiny feature" consists of hundreds of lines of code spread across 57 source files, many of which are less than 30 lines long, often contain more comments than code, and have no real reason to exist. It's the very definition of overengineering and overcomplexity.

        That said, I do find it somewhat funny that Anthropic themselves are falling victim to their own model's tokenmaxxing.

      • speleding 4 hours ago

        The Claude sandbox has a slightly different ENV compared to ChatGPT (LC_CTYPE set to C instead of UTF8 I believe) which upsets some scripts we have.

        So in the CLAUDE.MD we tell it about that and then tell it continue reading AGENTS.MD. Not very hard to work around if CLAUDE.MD goes away, but just to support your point that the split did have its uses for some.

          > Having a kill switch for the change is a perfectly reasonable safety measure in case something goes horribly wrong.
        

        Having a way for the user to revert the update is a perfectly reasonable safety measure in case something goes horribly wrong.

        Even though Anthropic or any other software provider could technically run anything on our system, there exists a modicum of trust between supplier and user. Anthropic performing arbitrary changes that are tangential but not specific to the premise of delivering a harness to package code files and prompts in context to their LLM breaks that trust for many users.

      At $FAANG, ~all changes go through feature flags.

      There are processes to make changes outside of feature flags, but they have enough friction that it's easier to just use a feature flag.

      This level of paranoia is consistent with the blast radius of changes breaking Claude users.

    I skimmed a couple pages of the docs at:

    https://github.com/user-attachments/files/31802150/EXTERNAL....

    Might I gently suggest that you have a model at least as capable as Opus 5.5 translate that from Claudish to English? Or, even better, have an actual human work on the docs a bit? As it stands, they are fairly egregious, and they seem to devote at least as much space to little AI-generated quips that convey no meaning than to actually explaining what’s going on.

    Also, maybe a human should decide whether these are “function” hooks or “module” hooks. All of this marketing calls them “function” hooks, but the json config seems entirely unaware of this.

    (Has anyone else noticed that half the sentences in Claudish aren’t merely weird: they are noun phrases and not sentences at all? I’m pretty sure that any decent pre-LLM NLP-based grammar checker would correctly flag half the sentences in Claudish. Also, whatever variant of Claude wrote this thing can’t even capitalize around semicolons consistently with itself, let alone consistently with how English has been written for at least a century.)

I was going to release it with a recommendation not to use Claude Code, but it’s at least plausible that this will change my mind. (I’m not sure yet — the $ mechanism might be too restrictive. It’s a start at least.)

    I've developed several plugins for different harnesses, and I needed some upstream change for most of them.

    The deciding factor for me whether or not I will work on the feature of the plugin is whether I (or rather, my agent) can look in upstream source and evaluate if it can be done with minimal upstream change, which I then contribute. And generally, even if no upstream change is needed, agents work so much better when they can read the code.

    So why not just make Claude code open source? Considering also that source code was leaked once anyway.

So what Anthropic calls "telemetry" is really "telechangeability"? That's sits with me even less comfortably than did the idea that some features are only available with telemetry enabled.

  • post-it 3 hours ago

    Not necessarily. They probably have an integrated service that handles some telemetry and also feature flags, like Braze. They toggled the whole thing off based on telemetry settings. It's a bug I've made before too.

    That's just how big companies roll out software changes for software that auto-updates.

    I fully believe GP that there was zero intent to gate this behind collecting telemetry. Sounds like a little tech debt and a little oversight, and the simplest explanation is that it is.

Hey, it seems you work there. I had a tangential question. Did any Anthropic exec threaten to do something unsavoury if any engineer ever tried to not name the claude cli binary as the version number itself? Because if they did, I'd understand. Or if you dare change it all the vibe-coded ts/react/etc dominoes will go for a fall in unison? I'd understand that too.

I can understand honest mistakes, but like, usually when I develop anything with agents (which I assume is what you're doing internally at Anthropic), they're almost too enthusiastic about trying to add test cases to the point where they sometimes try to glue together things in ways that are structurally impossible in the actual code in order to try to test that behavior. I'm honestly a bit mystified that adding a new feature didn't get bundled in with tests that the feature works for arbitrary configurations.

Really loved this Tibo-level responsiveness, if Anthropic can keep it up with this level of service, I am pretty sure a lot of people will just ditch their ChatGPT subscription and just move to Claude.

    On the other hand, if Anthropic is to follow the industry standards, this would never have happened in the first place. It's not like the feature gates are the frontier of software development.

              • d5lt5 4 hours ago

                There is a very valid reason on Windows not to allow people to do 'ln -s' without an admin.

                WSL also has a huge perf hit when you cross FS boundary, but perhaps you have never experienced it, because you said, "Ah, right. Windows..."

    • user43928 4 hours ago

      After I was mildly disappointed with GPT-6 Sol and Luna not improving intelligence and only cutting the price, I'm running Opus 5.5 today.

      After the last month or so in the Codex app, I was pleased with the Claude app.

      It might be a case of the grass always being greener on the other side, but this is what stands out:

      After 3-4 hours of usage, the weekly usage limit moved by only 1%.

      Compared to Astra where I can watch the limit draining live, this is a great improvement.

      I'd estimate it 3x cheaper, and that's with a 450k context limit instead of the 258k in Codex.

      So far Opus 5.5 appears less prone to stopping for no apparent reason at checkpoints in the middle of a longer task.

      It doesn't open an internal browser with a useless comparison page, where it then proceeds to add notes despite no one having asked for it.

      It is a breath of fresh air: I get the response in the chat, while the Codex app recently loves randomly opening artifacts instead.

      Opus 5.5 xhigh made great progress on the task, more so than Astra High, but that could be random chance.

      Oh, and the 'Auto' mode actually works and does not force me to instead run 'Full access' like in the Codex app, lest it blocks even 'git push'.

      • dannyw 48 minutes ago

        Don’t make too quick snap judgements. “Honeymooning”, or giving new subscriptions / upgrades extra usage or “juice” is pretty common industry practice amongst SaaS “growth hacking” for years. Sadly.

  • cowboylowrez 4 hours ago

    What we need is a low level but constant drumbeat against openai in general. In general the AI situation is overleveraged and underpoliced, with the occasional hints of AI gone wild. If openai were to just be left to die, we could let that financial mess unroll and bail out the leftovers, I don't like bailouts anymore than the next guy but with this administration its almost a guarantee if things go south because this adminstration can charge administrative fees of maybe $20-30 billion (which goes to trump), get Sam Altman to serve one or two years in a cushy resort type fed place for the hugging face hacking and put openai's processes on github as a premium feature, say $10000 a month to access (which again goes to trump).

    I know I know, why are we giving money to trump? Its because he's going to take it anyways so can't we at least apply some window dressing?

  • jimmaswell 4 hours ago

    Why would I ever do that to myself? My experience with Codex/GPT is fantastic, while my impression of Claude/Opus is that it's longwinded, patronizing, token-inefficient, stops to ask stupid questions every other minute, overcomplicates simple tasks, often poor engineering overall. I don't use it but this is what I see my partner run into who has access to both and compares them often. She has the same assessment.

    • michaellee8 3 hours ago

      Cuz OpenAI has been secretly downgrading models on many accounts, including mine lately. I paid $200 a month since like gpt-5.4, and since Astra released I found the model is somehow acting strange, it is until I checked X I have discovered that OAI is giving Luna level models when I am requesting Sol/Astra, or some piece of s** that is even worse than Luna. I basically had to ran every session with a Pelican test to determine if that session is safe. So I just spun up my Claude $20 and figured that now I can get all the work done just with Opus 5. Let me show you a pelican, by "gpt-6-sol". Cutting usages is one thing, but secretly downgrading models to a level that is not reliable anymore is the last straw. I am not saying other frontier labs (I am talking about you Anthropic) isn't doing this, but their version of downgraded/quantized/reduced effort model is at least usable, probably just slightly dumber, OAI's differences is day and night. https://imgur.com/a/PDbYdOQ

      • jimmaswell 3 hours ago

        Somehow this just hasn't happened to me. I use Astra on high all day for fairly intensive game dev tasks, sometimes cranked up depending on the task.

        I have heard ultra thinking might delegate to worse agents for some of its sub-tasks, but I don't use that much anymore since Astra came out. Just high seems good enough to throw most laundry lists at.

        • dannyw 51 minutes ago

          It’s more likely that GP encountered some bug or corner case or weird experiment conflating than anything intentionally deceptive.

          There’s also the fact that LLMs aren’t perfect, and sometimes even the best models act really stupid sometimes.

      • nullbio 3 hours ago

        It's night and day difference, for 3 days, until Anthropic nerf the model.

    > ...if Anthropic can keep it up with this level of service...

    fuckin laughable, literally invoked a laugh from me in real life.

    I hope customers aren't so stupid that they think a chatty developer on twitter/hn/mastodon/screaming-in-the-wind/wherever (or any other public-facing-place) means shit about customer service, and that goes towards ANY company where the primary customer service is an LLM.

    Anthropic is the only company where it took (!) 9 weeks (!) to convince to hand over a 4 dollar refund for book-keeping errors on their side that caused an inappropriately early account deactivation due to time zone issues on their end, while all the while telling me that they don't offer refunds. It took stacks of evidence and argument, and that was after spending two weeks in their system trying to convince every level that I was worth a human.

    For me personally it'd require Dario to resort to armed mugging to see another buck out of my wallet. I'm not alone.

    tl;dr : being able to convince the powers that be on highly active industry forums (hacker news, twitter, mastodon..?) to act right using the power of peer shaming doesn't good customer service make. That said -- I do appreciate the direct response/statement from mpoteat;

    ..I just don't appreciate the good actions of a decent individual being too broadly interpreted as the do-good customer-centric nature of Anthropic .. an element I do not believe exists there.

    I don't think "bug" is the correct term. They put a feature behind a feature flag, and feature flags don't work if you turn them off (via telemetry). That's "Working As Designed™".

    • mort96 4 hours ago

      It's clearly an unintended interaction. Nobody intended for the telemetry switch to control whether it reads AGENTS.md (hence mpoteat's apologetic response). Whether you consider that to be a "bug" or not really wasn't the point of my message.

      • _vertigo 3 hours ago

        Clearly not Claude-speak, see the rest of the message. "Rollout artifact" just means "an artifact of how we rolled this change out" which maybe isn't proper English but the message was obviously not written by Claude. Upgrade your Claudish detection

  • bbor 3 hours ago

    Feels pretty normal to me, IDK. "Rollout" is definitely what was happening here, and this leftover problem can be described as an "artifact" most generally - I guess otherwise it'd be a... just "problem" or "mistake"? Cause "bug" doesn't really fit. Plus, the Claudism here would definitely involve "soak", and possibly even "wall-time" lol

    IMHO it's worth keeping in mind that Anthropic employees are some of the least likely to casually pass off artificial prose as authentic, given the company's ethos/brand/cover story (depending on how cynical you are). To them this is all getting pretty high stakes pretty damn quickly; based on my usage of full strength Opus 5.5 today, I can't even imagine what working with their full internal stack must feel like. If they were willing to let the machines speak for them, they'd all be melancholically lounging around home by now instead of coming in to work!

    ...I am refusing to consider the fact that they probably are still WFH because of Salesforce forcing their shared security contractor to strike. Call that a mental health ignorance on my part :)
