onesie turns a Jev question into something a shell script can use. You pipe in some text, ask for example whether it conveys urgency, and get back a probability you can test, or an exit code that says run it, block it or ask a person.
It goes well beyond a single question. It can ask a batch with several running at once and pick up a large batch where it stopped, stream answers, keep questions in a file for reuse, test a script against mock answers, and calibrate a threshold against records you have already labelled, showing what each cut catches and flags by mistake.
It asks TypeSafe's Jev directly or through OpenRouter. You install it with Homebrew, an install script that checks the download, or Go, and a plugin can walk a coding agent through the setup.
