What it is
A collection of ten runnable JavaScript examples demonstrating how to use Jev for agent decisions such as memory reconciliation, tool-result checks, recovery, context selection, and handoffs. For developers building agents.
How it uses Jev
Jev makes small, independent judgments using Choice, Score, or Noul primitives on a given state. The answers are combined by explicit application policies in JavaScript to propose actions, with reasons written by the policy, not Jev.
Primitives:choicescorenoul
Technique worth stealing
Combine Jev judgments with application logic to handle edge cases in agent workflows.
Try it
Clone repo, run `npm start -- list` or `npm start -- run 02`; no API key needed for fixtures.
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.
