jev-cli
Ask Jev from a shell, and get an exit code back.
Shaharia Lab’s command-line tool asks yes/no, multiple-choice and rubric questions about any text and returns calibrated probabilities. Answers come back as exit codes for shells and CI, JSON for scripts, and MCP tools for agents.
### Ask any text a typed question. Get a probability back, not a paragraph. `jev` is a command-line tool for TypeSafe AI's **Jev** model, the model that never writes text.

You have text: a support ticket, a commit message, a user's answer, a product review, a model's output. You need a decision about it: is it angry, which team owns it, how risky is it, should this pipeline continue? Today you either write brittle keyword rules, or you ask a large language model and then parse a sentence it might phrase differently tomorrow. Jev is a third option. You define the
