What's Wrong?

Ok, it's not a major problem, but if I use the "Open Claude in terminal" function from the VS Code extension chat on Mac, I get this error:
❯ source claude
/Users/myuser/.local/bin/claude:1: command not found: \M-O\M-z\M-m\M-~^L
/Users/myuser/.local/bin/claude:2: parse error near `)'

It seems clear to me that the "source" command is being executed, which is trying to run the binary file claude.

What Should Happen?

Open Claude in terminal without errors
