Shell Tools
=============================

Demonstrates shell tools.

``run_shell_command`` executes an arbitrary command on the host OS. Under prompt
injection that makes the agent an RCE sink, so this example gates the tool behind
human-in-the-loop confirmation using the toolkit's ``requires_confirmation_tools``.
