The message

This becomes the state Jev reads. 0 / 12,000

Three question types

Everything Jev can answer is one of three shapes. Below, all three are answered against the same eleven-word state — the example straight out of the TypeSafe docs.

"Help! My payouts have been failing for 3 days."

Noul

Does this convey urgency?

Almost certainly

Probability the answer is yes

96%

No Coin flip Yes

A yes/no question comes back as a probability, not a word. 0.96 and 0.51 are different answers, and your code can tell them apart.

How a Noul works

Choice

Which team should handle this?

96% billing

One option out of a set you define, with the full distribution behind it — so you can see the runner-up and how close it was.

How a Choice works

Score

How frustrated is the customer?

1.24 of 2 · Frustrated

1.24

0 Calm 0%
1 Frustrated 76%
2 Very angry 24%

A rating against ordered levels you write. The answer is probability-weighted, so it lands between levels when the text does.

How a Score works

1 request

Nine questions, one call. Jev reads the state once and answers every question against it in parallel.

0 parsing

Answers arrive typed. No JSON mode, no retries on malformed output, no regex over prose.

3 primitives

Noul, Choice, Score. Every decision your software needs is one of these three shapes.

± confidence

Choice and Score carry a confidence value, so "I am not sure" is a branch your code can take.

Coming from an LLM?

The same routing decision written both ways — and where the retry loop goes.

Do we have ability to fix this in enmaas so we get the free auto mode? (Everyone should use auto-mode at this point and not yolo/dangerously-skip-permissions)
