All decision model projects

TypeScript library of decision contracts, confidence thresholds, fallbacks, human review and evaluation patterns on top of the TypeSafe SDK.

Dependency-free TypeScript library that converts raw app and game state into labelled bands and pruned lists that Jev reads reliably.

Vercel AI SDK layer that uses Jev to auto-approve, ask a human or block each tool call, and to prune irrelevant tools before a turn.

Unofficial TypeScript monorepo of Jev tools: a tool-call guard, a GitHub issue triage Action, a bulk JSONL/CSV sorter and a shared client.

Claude Code, Codex and pi plugin that hands non-writing agent steps to Jev and escalates writing or unsure steps to the LLM.

MCP server, CLI and Claude Code skill with Choice, Score and Noul primitives and a confidence gatekeeper, hosted or offline.

Unofficial standard-library-only Zig client for the System One API with answer types derived from questions at compile time.

Pure Dart client for Jev that sends state and typed questions from CLI, server or Flutter apps, tuned for low overhead.

Kotlin Multiplatform DSL and client for Jev that declares Noul, Choice and Score questions as typed properties, including enums.

Rails-native gem that defines Jev decisions as classes with typed results, confidence thresholds, guardrails, a router and test helpers.

Zero-dependency Node library with MCP and ACP adapters adding Jev decisions and gated computer use beside any LLM agent.

Unofficial async Python client for Jev with typed Noul, Choice and Score helpers, plus measured latency for batching up to 400 questions.

Grounded extraction where code proposes spans with exact offsets and Jev only classifies each one; a LangExtract alternative.

TypeScript library composing Jev judgments into deterministic threshold workflows that return explainable action sets.

Community Go client for the System One API with functional options, context cancellation and optional Langfuse tracing.

Unofficial standard-library Go client for the System One API with Noul, Choice and ScoreOf constructors and typed answer accessors.

Read-only, local Gmail triage that sorts each message into five trays with an urgency score using Jev via Vercel AI Gateway.

Python wrapper that answers System One and OpenAI Decisions API questions using any OpenAI-compatible chat model.

Semantic SQL for vanilla Postgres: jev() filters, jev_prob sorts and jev_choice groups are judged by Jev on rows after plain SQL runs.

Native R client that sends a state and typed questions to TypeSafe or OpenRouter and returns structured probabilities in R.

R client for TypeSafe's Jev with tidy helpers to run noul, choice and score questions over vectors and data frames.

Unofficial dependency-free Swift SDK for Jev with typed Choice questions over Swift enums, async/await, batching and retries.

C++20 library for typed routing, classification and scoring with compile-time enum schemas, local Laya and optional System One.

grep where the pattern is a description: each line, record, function or diff hunk becomes a streamed Jev yes/no question.

TypeScript library that binds a state schema and Jev questions into one artifact, validating state locally before asking for typed answers.

Rust crate and jud CLI where a decision is a .jud rubric file answered by a System One model, type-checked and testable without a key.

Open-source, self-hosted System One decision engine (NotJev : Kev) with a Jev-style API on top of Ollama or any OpenAI-compatible model.

Kotlin Multiplatform client for Jev that returns Choice and Score answers as your own enums, with no default thresholds.

Rust client for typed decision models across TypeSafe Jev, Cloudflare Clef, Liquid d1, Vercel AI Gateway and OpenRouter.

LangGraph decorator that lets Jev take routing decisions it is confident about and falls back to your existing LLM router otherwise.
