Does the AI understand irony and humor?

Often, but not always — and it doesn't pretend to have understood: when the tone is doubtful, it asks a direct question — "so this is for a repair, correct?" — rather than playing along with the joke. A sarcastic "great, another month of waiting" will sometimes be taken at face value, with a correct but slightly literal follow-up. The script's standing rule is clarity before comedy. And if your clientele runs on irony, say so at setup: we'll calibrate the style accordingly.
