Short answers drawn from the linked project or page.
Install it from npm with npm install @oortmem/decide-jev, then import jevDecider and call it with an apiKey, for example jevDecider({ apiKey: process.env.TYPESAFE_API_KEY }).
It decides what happens to each new fact: add, update, supersede, or skip. That four-way outcome is the whole decision surface the package exposes.
TypeSafe Jev returns typed answers with probabilities, so the add, update, supersede, or skip outcome arrives as a typed decision rather than free-form text.
Oort is open-source memory for AI agents, hosted at github.com/oortmem/oort. @oortmem/decide-jev is one piece of it; the main README explains how the pieces fit together.
The package is licensed Apache-2.0, so it can be used and modified under those terms.
It is a TypeScript/JavaScript package published on npm, imported as jevDecider from @oortmem/decide-jev, and it reads its API key from an environment variable such as TYPESAFE_API_KEY.
It is scoped to fact-level memory decisions inside Oort. If you are not maintaining an agent memory store that needs add, update, supersede, or skip outcomes, the package adds a dependency without matching your problem.
