What's Wrong?

When I try to create a Python file, Claude shows an "EACCES: permission denied" error and the file is not created.

The command fails immediately after accepting the file write permission.

What Should Happen?

Claude should create the Python file successfully without returning a permission error.

Steps to Reproduce

1. Create a file named test.py with the following content:

def hello():
print("test")

1. Ask Claude to modify the file.

1. Approve the file write permission request.

1. Observe that Claude returns an "EACCES: permission denied" error instead of modifying the file.
