-        key functionality of this script is:\n\n1. It defines a hash called `options`
-        to store any command-line arguments passed to the script.\n2. It creates an
-        `OptionParser` object and configures it to accept the `--who` flag, which
-        takes a `PERSON` argument. If the `--who` flag is provided, the script stores
-        the value in the `options[:who]` key.\n3. The script then checks if the `options[:who]`
-        key has a value. If it does, it uses that value to construct the greeting
-        message. If not, it defaults to greeting \"world\".\n4. Finally, the script
-        prints the greeting message to the console.\n\nThis script demonstrates a
-        common pattern in Ruby command-line tools, where the `optparse` library is
-        used to handle command-line arguments and provide a user-friendly interface
-        for the script''s functionality."}}],"stop_reason":"tool_use"}'
