If you were Meta designing this chatbot, would you plant hidden instructions for it in public pages, increasing the size of the page, and leaking what is internal info for everyone to see? Is this the natural design choice? Or would you give the chatbot its own API with the same text + the relevant instructions? Does not seem to me to be a sensible design choice. We are not in the days of using hidden HTML to communicate with internal subsystems.
