macOS How do I build a Safari plugin that can run a shell script?

I'm thinking of building a Safari plugin that would allow Web developers to cause Ruby scripts to be run on a client's machine. For security reasons, the plugin will ask for permission from the user before executing any commands that could adversely affect the user, such as modifying a file on the user's hard drive.

I have a solution to my problem. Instead of creating a Safari plugin, I'll create an AppleScript that is invoked using a URI scheme. When the script is invoked, it will download the Ruby script that is to be executed, then tell the Ruby virtual machine to run that script.
