What it is
A community Go 1.23 client for TypeSafe's System One API. It lets Go developers send a state plus typed Noul, Choice, and Score questions in one request and read back per-question answers.
How it uses Jev
The client sends the caller's state and mixed typed Questions to the default `jev-latest` model via SystemOne. Answers come back by question name: Nouls() gives probability of yes, Choices() a label, Scores() an expected score; unmodeled answer types are dropped with a warning.
Primitives:noulchoicescore
Technique worth stealing
Mix question types in one request; unmodeled answer types are dropped with a warning, so a newer API never breaks an older client.
Try it
go get serge.ax/go/typesafe-sdk-go, set TYPESAFE_API_KEY, call client.SystemOne.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
