harnessjudge

Minimal web demo: paste an agent step trace and Jev judges whether to continue, retry, escalate or stop.

Overview

HarnessJudge is a minimal demo for agent builders. After an agent step, you paste the trace and Jev returns a typed judgment: ok, retry, escalate or stop.

It illustrates using a decision model as a step-level supervisor in an agent harness. The README is very short, giving only the run commands, so details of the questions and thresholds are not documented. It is aimed at agent builders who want a quick look at how a decision model could supervise an agent loop: instead of asking a large model to reflect on its own step, the trace becomes Jev's state and the answer is one of four fixed outcomes that harness code can branch on directly. No benchmark, configuration or thresholds are documented.
