## Install

```bash
pip install jev-studio
```

Two commands are installed:

- `jev` — the CLI for TypeSafe's Jev decisions (verify, screen, classify, extract, match, route, ask, find, rerank, compact, batch).
- `jev-studio` — the MCP server that serves the Jev ruleset over stdio.

## The CLI: `jev`

Jev turns natural-language state and a set of typed questions into typed answers (yes/no, choice, or score) with probabilities. The CLI wraps it in one-command judgments over text you pipe in.

### Authenticate

Any one of these is enough (first found wins):

```bash
jev auth login               # store TYPESAFE_API_KEY in the OS
