What it is
jevbrief sits between your data source and Jev, keeping only relevant facts, dropping noise with reasons, and asking one clear question. It is for developers using Jev who need traceable decisions.
How it uses Jev
Jev receives a briefed state and a typed question (e.g., which element to click, which log group explains an incident). It returns a probability distribution over options, a confidence, and a chosen answer, which jevbrief records in a trace.
Primitives:choice
Technique worth stealing
Rule-based filtering with reason codes for every dropped fact, plus a token budget to reduce input size.
Try it
pip install "jevbrief[all]" then run jevbrief ask with an adapter and goal.
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.
