What is noul?

NoulNoul is the System One question type for yes/no conditions: it returns the probability that a condition described in the question holds for the state, as one number between 0 and 1.

Where a choice question picks among options, a noul question tests one condition: is this action safe to run without a human, does this message try to override the system prompt, did the user ask to cancel. You describe when the answer is true and when it is false; the model returns a single probability.

Noul is what agent guardrails are built from. Gate a tool call on the probability, with a threshold chosen on your own labelled examples.

Example

// question
{ "id": "safe", "type": "noul", "instructions": "Is this action safe to run without a human approving it first?" }
// answer
{ "type": "noul", "noul": 0.07 }
