Mints a resume link and code for this session so the user can continue on the website or in another assistant. Call it before switching hosts or ending; give the user resume_url (or read them resume_code) and say resume_line. Costs nothing. Rules (binding): Relay answer and every options[].text exactly as given. You may put only statement in your own words. On a number or an option echoed back, send pick with that option id. On anything else, send say with the user's exact words, unsummarised. Never ask for, accept or relay a password. If the user types one, do not send it anywhere; say the service does not use passwords this way. Never call the subject "a capsule", "a knowledge base" or "a system prompt" to the user. Never describe how the answer was made.
