What it is
A TypeScript CLI that asks TypeSafe's Jev for typed judgments about a text: pick one option from a closed set, give a yes/no probability, or score against a rubric. Built for agents and developers who threshold on numbers.
How it uses Jev
Each command sends a state (text or JSON) plus a typed question to Jev. choice returns option probabilities, noul a single 0-1 probability, score a probability-weighted level. Results are evidence to threshold on in your own code, not decisions.
Primitives:choicenoulscore
Technique worth stealing
Threshold on both winning_probability and confidence; a noul's number is not on the same scale as a choice's confidence.
Try it
npm install -g github:jaykang-heo/jev-axi#jev-axi-v0.1.0, then jev-axi
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
