Claude fails to use `rtk proxy` because of quotes

I just witnessed Claude Code run:

rtk proxy 'head -50 app/Models/Domaine.php'
Error: Failed to execute command: head -50 app/Models/Domaine.php

Caused by:
    No such file or directory (os error 2)

After debugging I figured out that it should have run:

rtk proxy head -50 app/Models/Domaine.php

i.e. because of the quotes it messed up the invocation.

Should:

• Claude instructions be clarified to avoid CC adding quotes?
• or rtk proxy automatically un-quote if it gets 1 argument with quotes?
