What it is
An Agent Skill for coding agents that sends closed judgments to TypeSafe Jev and acts on the returned probabilities, so the main coding model keeps writing code and interrupts the user only when a person must decide.
How it uses Jev
Jev is called at three points: before asking the user a closed question, before a command that may destroy data, leak secrets, or reach beyond the task, and after a command fails. The bundled scripts/jev.py posts {state, questions} to the TypeSafe API and uses the probabilities to proceed or ask.

Technique worth stealing
Keep the main coding model writing code while a separate typed judgment model answers closed questions.

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.
