Very good fix, absolutely no reason to chdir in this case. 🤦‍♂️

I wonder if the rescue nil removal can be dangerous? Unfortunately not aware of its root cause of being there though.

Yeah, I was thinking about that too. I wasn't convinced it was needed, but it's probably safer since passing nil into File.file? or Dir.glob can raise an error

not 💯 this will work, but tests pass. Seems like we might need to pass the path to the config command.

same here, I think we need to utilize the path variable in the config command if it exists
