  • jev_askAsk Jev (several questions)read-only

    Send one shared context and one or more independent questions to Jev (TypeSafe System One) and get typed judgments back — not prose. How to design the call: - `state` carries the text and facts; `instructions` carries the judgment, in the question's own words. - Every question is answered independently against the same state. Order is not a sequence, and no question can use another's answer. Ask independent questions together in one call, including conditional ones whose answers you may ignore; make a second call only when an answer decides what to fetch or ask next. - One call judges one sta…

  • jev_batchJev batch (many items)read-only

    Description is built at runtime.

  • jev_choiceJev choiceread-only

    Ask one question whose answer is exactly one of a set of options you define. Use for a category, a route, or a selection from a closed list — not for a degree and not for a yes/no. Write the judgment in `instructions`, and put the boundaries in the option descriptions: what each option covers and excludes. Include an option named "other" or "none" when the list may not cover every input. A choice returns exactly one option, so ask separate noul questions (together in `jev_ask`) when several labels can apply at once. Returns the selected option, the full probability distribution, and `confide…

  • jev_noulJev noulread-only

    Ask one yes/no question and get its probability. Use when the condition either holds or does not, and the probability is more useful than a category. Name the condition precisely in `instructions`; optionally describe the two outcomes in `criteria.true` and `criteria.false`, or omit `criteria` when the instructions already define both. Returns a value between 0 and 1: near 1 yes, near 0 no, near 0.5 uncertain. It measures probability, not intensity, and there is no separate confidence field — a confident no is near 0, not near 0.5, so read low values as evidence against rather than as low co…

  • jev_scoreJev scoreread-only

    Ask one question whose answer is a position on an ordered scale you define. Use for degree, severity, or intensity. `criteria` lists the levels from lowest to highest; a three-level scale returns a score from 0 to 2, and values between integers are positions between levels — the score is the probability-weighted mean of level numbers, not a percentage or a category id. Give every level a self-contained description ("no deadline expressed", "wants a response soon", "explicit deadline"), never a relative one like "more urgent than the level below". Returns the score, the `legend` mapping level…
