Rust CLI that sends each code chunk to Jev with one plain-language question, one chunk per request, and returns the functions ranked by probability. A sweep of the 819 functions in its own repo costs $0.0049 (author).

The README opens with

Powered by Jev, TypeSafe AI's System One model. It returns a calibrated probability instead of prose, which is what makes reading every function affordable rather than sampling a few.

That is demo/ in this repo, so you can run the same line and get the same two hits. The other three queries there bind their parameters and are left alone.

You already know how to find .unwrap(). You do not know how to write the regex for "retries without backoff", so today you guess a few patterns and hope.
