Crazy part is: can’t tell if this intended or a bug
vaylian•36m ago
Can you think of a bug that makes sense in this case?

thejazzman•28m ago
It is most certainly the kind of subtle bug the LLMs love to slip in and burn you in production

Not sure what y’all are thinking with these unwritten conspiracy theories that begin and end with “it’s intentional”

jpitz•34m ago
Assuming that it's intentional, what's the motivation?
kennethops•33m ago
I like to give my graces to people and the companies who are typically not trillions of dollars. Have an incredible amount of resources that many countries would like to have, with fewer of the obligations. I'm going to chalk this up to its intended
serial_dev•32m ago
Someone on the Claude Code team is probably wondering the same...

Claude/Anthropic has been sus from the start:

+ not letting users change their email, or remove their payment methods, etc.

jaapz•15m ago
many of these can also be chalked up to the fact that all of their products are extremely vibed

Nice find, though I'd rather read the prompt that was used to write this article. It is about ten times longer than it needs to and is quite painful to read.
sandrello•32m ago
Based on my experience with these tools so far, this seems exactly the kind of subtle but extremely severe bug that sneaks in when you start piling up layers of AI generated patches to a codebase without caring too much about the code.
hgoel•26m ago
Yep, especially with long contexts (and moreso if the last thing you were working on in the same context involved telemetry too). AI sneaks in weird conditions like this and then does the entire "You're absolutely right" thing if you're paying enough attention to catch it.
crazygringo•16m ago
It seems to be exactly the opposite, a "fully human error":

Nothing to do with AI patches at all, nor was it a bug. It was intentional human behavior, a temporary rollout setting, that seems to have made sense.

tpurves•3m ago
Except that, and this I find slightly amusing, is a situation where they definitely don't want to publicly blame the ai model when there are mistakes.
Agentlien•3m ago
I used to actively use Msty for local models because it just worked and had a lot of nice advanced features. A few months ago they released their beta version of a Claw-like UI and mentioned using a version of it to develop Msty itself. Well, that was around the time I stopped using Msty because every update started breaking things and two updates in a row included bugs which wiped all my configs, chats, and history.

Issue 95690, opened 3 days ago, 500k+ engineers, a simple CLI...

AGI was reached like 2 weeks ago, latest claude 5.x models rule supreme and oftware engineering is solved?

lucfranken•29m ago
Isn't that how they just release all features? So they can do progressive roll outs and telemetry on issues with it?

Not sure if they later move the code from inside the flag check to the main code or that they keep the flag check.

But if they would keep all features behind a flag that would not make most sense as you then would have not many features without telemetry.

vorticalbox•28m ago
I use cursor and claude, its kinda annoying having to have the same skills in both so I made a ~/.agents/skills folder then ln both cursor and claude skills to point to that folder.

which works except that claude uses .skills/synced which is uses to sync changes to skills from claude servers into the skills folder.

every other agent I have used just directly syncs into .skills so it ends up duplicating skills

0m13•27m ago
can i ask claude to change these settings for me, and will it enable telemetry as implied checkpoint when i ask it to enable AGENTS.md?

I am once again (for the third time) [0] asking you to stop using a closed-source harness.

teekert•24m ago
Uhm I turned off everything there is to turn off in my Pro plan, and Claude just read my agents.md with no issue? So... What telemetry am I missing? Or did they JUST update? (I updated my docker image 40 minutes ago to get Opus 5.5, am on version 2.1.280, so not the mentioned 2.1.277, so it's fixed?)
mpoteat•23m ago
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.

piltdownman•22m ago
Much respect for the prompt response, humility, and frank disclosure.
mpoteat•18m 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.

rickette•10m ago
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.

This is beyond comprehension. Claude Code lately just comes across as hostage-taking, forcing users into absurd rules. I have tried hard to give it the benefit of the doubt. This is too much. It is basically poisoning the code.
tehlike•10m ago
Not everything is malicious. The author of the feature already responded on why this happened
arrowsmith•18m ago
Claude Code also doesn't read AGENTS.md by default if there's a CLAUDE.md it can read instead. This isn't limited to your repo, e.g. if you have a ~/CLAUDE.md then no AGENTS.md will be read.

To always read both, you have to switch the 'Project instructions' setting to the non-default `claude-md-and-agents-md`.

Just in case anyone is wondering why their AGENTS.md still isn't being read.

gmponyo•9m ago
This is not the only case where Anthropic has done stuff silently without giving users any information about changes that would hurt them.
cowpig•5m ago
The number of people raw-dogging software that executes arbitrary instructions on their machine coming from a 3rd party server just absolutely baffles me.

The same people who've spent years of their career making sure that never happens.

pmlnr•4m ago
Urm... no tests caught this? How?
11m ago
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.
grim_io•10m ago
The same guy writing readme's for my vibeslopped toy projects is also the readme writer at Anthropic, what a coincidence ;)
Maxion•10m ago
Well now, this is how you do community outreach
aviperl•7m ago
Ouch.

I've had to send such messages, but internally at work, not on HN!

Have a great day, human.
