Obviously you'd have to give it a scope with requirements, outcomes/expected results. Ideally I'd have a file somewhere then use voice activation to tell the bot to build a website based on the parameters in that file.
Then it would show you a real time coding in text editor then how it looks in a browser (this is just a basic macro type thing). That way you can say "pause" or any number of commands to check it's work/progress/change any individual thing that it can't overwrite because the bot would recognise a "master override" or something
