Jev AgentA source-verified directory of 487 Jev projects — browser agents, model routers, SDKs and MCP servers — each one showing the exact decision it hands to Jev. Curated by the Awesome Jev community, mirrored here under MIT.
Give Jev the current state and a few options. Get the Agent’s next step.
Core call · setup in the full example
const nextStep = choice("What next?", { login: null, askUser: null, retry: null });
const { answers } = await client.systemOne({ state: "Login form is ready", questions: { nextStep } });
console.log(answers.nextStep.choice);Node.js 20+ · Set TYPESAFE_API_KEY on your server. This page shows code and makes no model requests.
An optional Jev classifier integration for Python LangChain workflows.
Submits binary, categorical and ordered-score questions and returns typed answers with probabilities.
Adds a classification step that can participate in existing LangChain pipelines.
An optional TypeSafe provider and Jev model integration for Pydantic AI.
Converts supported structured output fields into typed Jev questions and maps answers back to the output model.
Lets supported classification outputs use the existing Pydantic AI interface.
Ax provides a TypeSafe integration for boolean or finite-class signatures and native Jev answers.
Maps supported signatures to Jev questions or sends native System One requests.
Reuses structured signatures and Jev probabilities within Ax workflows.
A TypeSafe provider for RubyLLM 2 that exposes Jev’s three judgment types through structured output.
Builds Noul, Choice and Score questions with Schema and returns answers to the RubyLLM application.
Reuses the structured-output interface in existing RubyLLM programs.
A Laravel adapter for Jev with configuration, dependency injection, a Facade and a request-recording test fake.
Wraps a community PHP SDK for typed judgments and preserves promises and exceptions.
Fits Jev calls into Laravel services, queues and existing tests.
A Spring WebFlux integration that detects error messages hidden in HTTP 200 response bodies.
Jev checks for hidden errors or maintenance notices; a local threshold raises a business exception.
Lets existing error-handling code see failures concealed by the HTTP status.
A community-maintained directory and radar for Jev, highlighting open-source projects with verified code and clear decision architectures.
Jev is TypeSafe's decision model. This directory groups projects by how they use choices, scores and probability judgements, with implementation links to help you assess fit for your own task.
TypeSafe ↗We prioritize open-source projects with clear Jev implementation evidence. Repositories without verifiable source code are excluded from the main directory.
