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: <a href="https://github.com/anthropics/claude-code/tree/main/mods/agents-md" rel="nofollow">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.

  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: <a href="https://github.com/anthropics/claude-code/issues/91870" rel="nofollow">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.

    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.

    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.
