No. Do you realize how much of a joke Claude code is? Under the hood. How they implemented client auth?

Well let me tell you

You literally send your first message “you are Claude code”

The fact that this ever worked was insane.

Headline is more like anthropic vibes a bug and finally catches it.

Is there any other way to do it though? Even if they implemented some form of auth logic, since it's all client side anyone could spoof it. The only real way to distinguish Claude Code from non-Claude Code is behavioral analysis (e.g. system prompt, set of tools, etc.). Or engage in a cat and mouse game of increasingly obfuscated challenge/auth.

That sort of mechanism is not a "joke" and is often used for trademark/legal reasons, not technical ones.

Both Nintendo and Sega tried that, and it did not work as they legally intended.

The joke is that AI companies pretend to care about doing legal things.

Tonight we are all Claude Code, Anthropic's official CLI for Claude.

There is no way to prevent people from using a custom client.

[notpushkin]

There are ways to make it painful. Though it would probably be painful for “legit” users, too.

Game developers disagree...

So now you just need to remove the “read” tool to authenticate?
