What's Wrong?

I am attempting to debug LSP issues by enabling verbose logging as described in the documentation (CLI Reference). However, when running the command, the CLI exits immediately with an error stating the option is unknown.

What Should Happen?

Claude Code should start the interactive session with verbose LSP logging enabled, writing logs to ~/.claude/debug/.
