가드레일 및 안전

모델 추론과 도구 사용을 중심으로 컨텍스트 관리, 이벤트 스트리밍, 메모리, 권한 제어를 갖춘 에이전트를 구성합니다. JevClassifierModel은 TypeSafe SDK를 통해 이 범용 프레임워크에 Jev 분류기를 통합합니다.

네이티브 CLI가 대화형 셸, 스크립트 요청, 다른 시스템에 내장해 사용하는 방식을 지원하며 스킬, MCP 서버, 하위 에이전트로 확장됩니다. Jev가 검토 정책, 컨텍스트, 대기 동작을 받아 권한 처리 흐름에 clear 또는 caution을 반환합니다.

awesome-jev-by-typesafe는 출처가 있는 Jev 활용 사례, 프롬프트, 패턴, 시작 코드를 모은 독립 커뮤니티 자료입니다. Choice, Score, Noul로 분류, 라우팅, 검증하는 방법을 설명하며 제어 흐름은 코드에 둡니다. Python과 TypeScript 예제를 살펴볼 수 있습니다. 오프라인 정책 테스트는 키가 필요 없고 실제 호출에는 TYPESAFE_API_KEY가 필요합니다.

Jev Review는 Git 변경분이나 전체 코드베이스의 정확성, 보안, 신뢰성, 호환성, 테스트 범위를 살펴봅니다. Jev가 증거를 선택하고 문제 메커니즘과 심각도를 평가하며, 조건에 따라 Choice로 검토자를 선택합니다. 임계값과 워크플로 정책은 코드가 적용합니다. Node.js 24+, Git, TypeSafe 키로 JSON 보고서를 만들거나 저장된 검토를 로컬에서 확인합니다.

Real-time Discord moderation bot: Jev evaluates messages and metadata in parallel to catch phishing, spam, and social engineering with a progressive escalation ladder.

Auto mode for every coding agent, built on Jev: risk-scores every tool call with session context (deny / ask / allow), flags prompt injection in results, checks skills and plugins. Claude Code, Codex, Copilot, Gemini, Cursor, pi, OpenCode, ACP.

Typed-judgment admission control at the traffic edge: three-layer prompt-injection and abuse filter for nginx/OpenResty, powered by TypeSafe Jev. Fail-open, cached, hot-reloadable.

Self-evolving cognitive decision engine & TypeSafe Jev alternative. Deliberative decision flywheel ('explore first, crystallize later' System 2→1) with 100% option-order invariance. Typed probabilistic API (Choice, Noul, Score) for Open LLMs, Laya (ModernBERT), & commercial Jev with calibrated logprobs and adaptive safety guards.

A Clash Royale bot with no trained policy: Jev (TypeSafe System One) makes every decision from the live game state

Typed judgment tools for MCP agents. TypeSafe's Jev model as verify, screen, find, classify, rerank, decide, compare, extract, review, gate, and score: the model judges, policy decides auto, review, or escalate.

位于 nginx 与大模型后端之间的前置过滤反向代理：逐请求提取用户输入交给 JEV 判定，有害拦截、正常透明放行

A minimal permission gate for Pi in the style of Claude Code's auto mode

A curated, evidence-led directory of DeepSeek Harness (DSH) plugins: verified loadable extensions, skills, and permission-aware installation guidance.

Compile agent policy prose into deterministic verdict programs: narrow evidence questions for the model, the verdict computed in code. Install: npm i -g jev-compiler

Input moderation for Mastra agents on TypeSafe Jev — one file

Decision maker for Ruby: turn decision model answers into policy verdicts

Fast System-1 Decision, Arbitration & Safety Engine for Autonomous AI Agents (Powered by TypeSafe Jev)

基于 Jev 的聊天决策辅助：读当前聊天窗口，只返回类型化判定与置信度，不生成回复。QQ / 飞书 / 抖音实测可用。· An on-device chat co-pilot built on Jev — typed verdicts instead of prose, no package allowlist.

An automated Discord moderation bot, powered by Jev.

Experimental Jev permission gate for Claude Code via OpenRouter, with reproducible latency and cost benchmarks

Effect-based safety gate for AI coding agents' shell commands (OpenCode, Antigravity): fast structural rules, then TypeSafe's Jev or a chat model judges what a command does. Certified with Jev at zero dangerous commands allowed.

Shift every LLM call to the cheapest model that can handle it. Routing decided by TypeSafe Jev in ~180 ms. No training data. Policy in plain YAML. TypeScript and Python.

Blind security benchmarks for Jev, TypeSafe's System One model: prompt injection and vulnerable code detection, built on jev-go

A governed execution layer between typed-decision models (TypeSafe Jev) and agent/AI tooling like Claude Code, MCP, and AI SDKs, turning probabilistic decisions into deterministic, policy-controlled, and auditable actions.
