What it is
Adds a measured tool-call gate to the Pi coding agent so risky calls are checked by Jev before execution. Also judges bash output and provides a jev_ask tool for typed, calibrated answers.
How it uses Jev
Jev answers typed questions about a piece of state. The gate judges bash, write, and edit calls before they run. An output judge reads what a bash call printed. jev_ask lets the model ask for the same kind of judgement itself.

Technique worth stealing
Use measured thresholds from calibration runs, not chosen ones, and fail open on every error path.
Try it
pi install npm:@y0usaf/pi-jev
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.
