pi-jev

y0usaf/pi-jev

TypeSafe Jev as a decision layer for the Pi coding agent.

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.

Primitives:choicescorenoul

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
