What's Wrong?

I keep getting the following error on my command line when I run claude

> claude
fish: Unknown command: /Users/rpollock/.claude/local/claude
- (line 1): 
function claude --wraps /Users/rpollock/.claude/local/claude --description 'alias claude=/Users/rpollock/.claude/local/claude';  /Users/rpollock/.claude/local/claude $argv
                                                                                                                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
in function 'claude'

This seems to happen after I install claude and I think an auto update runs. Immediately after installing claude it works fine on the command line.

What Should Happen?

Running from the command line should start claude, no error.

Steps to Reproduce

I am using fish shell. I don't know if that's required for the bug. I have NPM and NodeJS from homebrew.

1. Install using npm install -g @anthropic-ai/claude-code

1.1 Run claude, it works!

1. Wait a while. I have not figured out how long.
2. in a new terminal run claude, it does not work.

Claude Model

None

Is this a regression?

Yes, this worked in a previous version

Additional Information

This is reproducible in iterm and kitty terminal as well as IDEA.

I run functions -e claude and it fixes it until the function comes back.

In /status I see this

  ⚠  Config mismatch: running npm-global but config says local

but when I run /doctor nothing is changed.
