What it is
A community-maintained Go client for TypeSafe AI's Jev / System One API, for Go developers who want to ask typed questions over state and read calibrated answers.
How it uses Jev
Callers send a state plus named Noul, Choice, and Score questions via Ask or SystemOne. Jev returns answers keyed by name; code reads the type-specific field (Choice, Noul, Score) after checking Answer.Type.
Primitives:choicescorenoul
Technique worth stealing
Explicit answer discriminator with type-specific fields, since Go cannot infer heterogeneous map value types like the TypeScript SDK.
Try it
go get github.com/stumble/jev-go, or go install github.com/stumble/jev-go/cmd/jev@latest for the CLI.
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.
