What it is
TypeSafe Jev is a "System One" decision model: it evaluates typed questions (Noul / Choice / Score) against a state and returns structured answers with calibrated probabilities. This plugin exposes it to Hermes Agent as four tools, focused on coding-agent workflows.
Getting started
From the README:
hermes plugins install ajensenwaud/hermes-jev-pluginWhere the decision sits
hermes-jev-plugin calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.
Models it references: Jev, jev.

We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
