elbruno/ElBruno.AI.JevC#
elbruno/ElBruno.AI.JevC#A C# client for the TypeSafe System One API with one dependency, a faithful port of the official Python SDK's behaviour, and typed answers bound to properties by name.

brightshore/jev-netC#
brightshore/jev-netC#An unofficial Go client that keeps Jev answers in your own types, so a choice over your enum yields that enum and the compiler checks the switch you write on it.

anilsenay/jevGo
anilsenay/jevGoUnofficial Go SDK for TypeSafe AI's System One API, kept deliberately minimal: one client, a state map, a map of typed questions, and answers read back by question id.

guillemus/jev-goGo
guillemus/jev-goGoA pre-release .NET decision library that keeps the domain in a dependency-free Core assembly and reaches Jev through a pluggable provider, so changing vendors does not mean rewriting your application model.

iamjonatha/decisionkit-dotnetC#
iamjonatha/decisionkit-dotnetC#An unofficial async Rust client for the TypeSafe System One API in which each question hands back a key typed by its answer, so reading a choice answer as a probability fails to compile.

JedimEmO/typesafe-clientRust
JedimEmO/typesafe-clientRustAn unofficial Java 21 client for the Jev decision API that replaces maps with records and sealed types, so a malformed choice, score or noul question fails to compile instead of coming back as a 422.

unimtx/typesafe-sdk-goGo
unimtx/typesafe-sdk-goGoTypeScript router that spends one Jev call deciding how an agent turn should run — model tier, effort budget, which tools are on offer and which skill applies — then your own harness runs the turn on whatever provider it already talks to.
Jev Repos & SDKs#community#awesomejev#catalog-import
Unofficial Ruby client for TypeSafe AI: typed noul, choice and score answers, retries with jitter and Retry-After handling, per-call timeouts, a structured error hierarchy, and request-shape validation before anything goes over the wire.

kyledickey/jev-goGo
kyledickey/jev-goGoC# client for Jev, TypeSafe AI's System One model. Typed Noul, Choice and Score questions go out with one state in a single round trip and come back with a value, a probability distribution and a confidence number. Choice questions can be built from an enum, so the compiler finds the switch branch you forgot.

kataras/jevGo
kataras/jevGoA Go repository around the TypeSafe System One API that also ships a released CLI and a VS Code extension. SysOneScript scripts run offline, semlint inspects source and proposes checks, Studio is the editor front end, and the typesafe subpackage talks to Jev from your own module.
Jev Repos & SDKs#community#awesomejev#catalog-import
A Java and Maven framework that lets natural language route to existing tinystruct @Action methods: Jev picks the action and its arguments as a probability distribution over options you supply, and the dispatcher then runs, holds for confirmation, or refuses.
