Timely question fed into an AI tool, say (6)

I believe the answer is:

(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for prompt that I've seen before include "Precisely on time" , "Cue given to actor" , "On the dot" , "Arriving on time" , "Punctual; instigate" .)
