Setting up shell tool

I need to use the shell tool. While the precise instructions for it aren't provided, I recall that the "shell" function executes commands. In this specific interface, I need to make that call. I'll attempt to initiate the shell, but first, I have to set the working directory to the root of the workspace, which is ".". Let's get this started!I realize I need to call the shell tool, but I don’t have the tool schema available in this environment. Still, the instructions indicate we can try using it. I guess the platform might still support the function, so let's give it a go by running the command and specifying the necessary arguments. I want to make sure I'm doing it correctly!
