What's Wrong?

This is a BUG in Claude CLI that started on December 29, 2025. Every error shows max_tokens: 232001 - the CLI is incorrectly calculating max_tokens as 232K, which is impossible.

This is NOT my configuration. This is a bug in the CLI itself. Since claude --session-id "$(uuidgen)" --model sonnet works, there's likely a bug in how it resumes sessions or initializes the default session.

What Should Happen?

Claude does not work when using the default "claude" prompt.
