Noul

A yes/no statement. The answer is the probability that the answer is yes, with a confidence that is the larger of it and 1 minus it.

Request

{"state": "I have asked three times now. Can I please just talk to a real person?",
 "questions": {"wants_human": {"type": "noul", "instructions": "Is the customer asking for a human agent?"},
               "repeat_contact": {"type": "noul", "instructions": "Has the customer contacted support about this before?",
                                  "criteria": {"true": "Mentions a prior attempt, ticket, or having asked before",
                                               "false": "No sign of any previous contact"}}}}

criteria is optional and describes what true and false mean when the boundary is subtle.

Answer

{
 "wants_human": {
  "type": "noul",
  "noul": 1.0,
  "confidence": 1.0
 },
 "repeat_contact": {
  "type": "noul",
  "noul": 0.549,
  "confidence": 0.549
 }
}

Thresholds

The number is both the answer and its certainty. Set the threshold by the cost of each error:

YES, NO = 0.8, 0.2
if NO < value < YES:
    send_to_human_review()
elif value >= YES:
    take_yes_action()
else:
    take_no_action()

Guidance

• One condition per Noul; "angry and asking for a refund" is two questions.
• Phrase for yes, in plain words; inverted phrasings ("is it not the case that") read worse.
• A Noul measures probability, not magnitude: for "how much" use Score.
• A stray answer near the threshold happens. If an action is expensive, check the condition in code (a memory rule with when, or derive) or count the answers, as the roulette demo does.
