Framework integrations with decision models

Adapters that bring decision calls into existing frameworks such as LangChain, LangGraph, DSPy, the AI SDK, Spring or workflow tools.

  • Agent tool router that keeps obvious calls on a fast path, uses Jev via OpenRouter for ambiguous tool choices, and offers bounded MCTS.

    MCP serverprototypePython
  • Experimental Hono router that matches HTTP requests to plain-language route descriptions using one Jev Noul per route.

    ProjectprototypeTypeScript
  • Beginner manual, video script and three small examples for building an agent harness with Jev via langchain-typesafe.

    ProjectprototypePython
  • Scaffold of n8n workflow patterns using Jev for PII screening, agent guardrails as hooks, and workflow evals with Jev as judge.

    Projectprototype
  • Python library to batch, gate, trace and calibrate thousands of typed Jev decisions, maximising questions per call.

    ProjectprototypePython
  • Companion code comparing Google ADK and Microsoft Agent Framework for structured video timelines, with Jev as a shared per-segment QC gate.

    LibraryprototypePython
  • Typed, budget-aware language for LLM agents compiling to Python/TypeScript, with a decide{} block for Jev-family decisions.

    ProjectprototypeNudge (compiles to Python and TypeScript)
  • Pilot that puts Jev into LangGraph routing and Deep Agents guardrails and claim verification, with executed notebooks and caveats.

    ProjectprototypePython
  • Rust LLM application framework with an experimental rig-typesafeai crate for typed Choice, Score and Noul Jev queries.

    LibraryprototypeRust
  • ComfyUI custom node that asks Jev noul, choice or score questions inside image-generation workflows, e.g. to pick a workflow template.

    ProjectprototypePython
  • UiPath bring-your-own-guardrail connector that runs AI Trust Layer llm_as_judge checks as Jev noul questions.

    ProjectprototypeJavaScript
  • Rails engine for voice and typed commands: define actions in a Ruby DSL and Jev picks the matching command or page control.

    ProjectprototypeRuby
  • Portuguese workshop: a LangGraph sales agent where each decision step can be made by Jev or a frontier LLM and measured side by side.

    ProjectprototypePython
  • 248 small installable TypeScript recipes that each make one typed Jev decision: route, rerank, gate, grade, compare or label.

    LibraryproductionTypeScript
  • Milvus's model library with a Jev reranker that sends candidate documents as yes/no relevance questions and returns them sorted.

    LibraryproductionPython
  • Pydantic's Python agent framework, which list sources say ships a TypeSafe provider that maps Pydantic output types to Jev questions.

    LibraryproductionPython
  • Ruby-native AI framework with one API across 19 providers, including a TypeSafe provider for Jev's typed judgments.

    LibraryproductionRuby
  • Community Java 17 SDK for Jev with typed Ask declarations, enum-backed choices and a Spring Boot starter.

    LibrarybetaJava
  • Zero-dependency Python SDK for deterministic gates over calibrated model answers, with LangChain, OpenAI and Claude agent hooks.

    LibrarybetaPython
  • Vercel's AI SDK for Python, in public beta, listed for carrying Jev through its evaluation operation and AI Gateway examples.

    LibrarybetaPython
  • Effect library turning Jev Choice, Noul and Score answers into typed branches with a compiler-enforced Uncertain case.

    LibrarybetaTypeScript
  • Community .NET 10 SDK giving one API for choice, score and assessment over Microsoft-Decision-1, Ollama or native Jev.

    PluginbetaC#
  • Small Go agent-loop library with an optional goodall/typesafe package that uses Jev as a tool or hook beside chat models.

    LibrarybetaGo
  • Ruby gem for probabilistic control flow: branch on Jev answers with predicates like likely? and almost_certainly?.

    LibrarybetaRuby
  • Ruby gem making semantic checks ordinary methods: feels?, decide and score on model fields, with Rails validations.

    LibrarybetaRuby
  • TypeScript guardrail library plus DeepSeek Harness plugin screening prompts, tool calls, results, responses and claims with Jev.

    LibrarybetaTypeScript
  • Multi-provider Java SDK for Jev via TypeSafe, OpenRouter, Vercel or Cloudflare, plus OpenAI Decisions and Spring Boot support.

    LibrarybetaJava
  • Framework-agnostic PHP SDK for TypeSafe's System One API with typed Noul, Choice and Score answers, PSR-18 and Laravel support.

    LibrarybetaPHP
  • Type-safe Java 21 client for Jev's System One API using sealed interfaces and records so invalid requests fail at compile time.

    LibrarybetaJava
  • LangChain and LangGraph middleware that screens tool outputs for prompt injection and gates risky tool calls with Jev.
