What's Wrong?

I am using Docker so wanted to use the OAuth token instead of browser authorization. On my host I ran claude setup-token which gave me the token and stated: Use this token by setting: export CLAUDE_CODE_OAUTH_TOKEN=<token> but to get claude CLI to use the token in the Docker container I needed to, instead, set ANTHROPIC_AUTH_TOKEN

The user experience when running Claude inside a container is poor. The browser authorization is not providing an option to get a code that can then be copy pasted into the Claude CLI. It is frusrtating that claude CLI asks for a code to be copied in but there is no explanatin of how/where to get this code (and it is not the OAuth token it seems.

What Should Happen?

Use the correct env variable name in the message or in the code.
