A Kubernetes admission webhook that asks Jev to allow, flag, or deny a manifest change for intent-shaped policies a Rego rule cannot express, keeping hard rules in Rego and failing closed by default.

Laya Typed-Decisions

The fine-tuned Laya checkpoint for four typed-decision workflows: 0.766 accuracy on 2,000 held-out decisions, above Jev 1.13.0's published 0.727 and the teacher self-agreement ceiling it trained past.

Security-One 27B

Superagent's security triage model: a continual fine-tune of AutoJev-27B that returns calibrated probabilities for prompt-injection and content checks, with a release policy at 0.70 unsafe.

Laya Demo

The official Laya playground: eight tabs that show choice, score, and noul decisions on ticket triage, phishing, guardrails, RAG filtering, moderation, routing, and multilingual text.

WorldMonitor

88.2k

Real-time geopolitical intelligence dashboard that uses TypeSafe Jev questions to score news headline severity into five threat levels and categorize events across 14 conflict, cyber and infrastructure domains, alongside news aggregation and a Country Instability Index.

openclaw-jev-leakguard

OpenClaw plugin that checks every outgoing agent message against its destination channel tier, running local key-format and term rules and then five Jev Noul questions in one call through OpenClaw's decisionModel, which can point at hosted Jev or a local Kev.

Jev Tools & CLIs#community#openclaw#guardrails

yousan/openclaw-jev-leakguardJavaScript

dsh-jev-interceptor

A DeepSeek Harness plugin where Jev Choice and Noul checks gate every non-read-only tool call - deny confident high-risk calls, escalate ambiguous ones, auto-approve clearly granted reversible ones - and optionally score session messages so valuable context survives instead of being dropped oldest-first.

Jev Tools & CLIs#community#plugin#guardrails

Community

AskTheWay/dsh-jev-interceptorTypeScript

Ring Zero Security

Kernel-enforced runtime security for AI agents with eBPF/LSM: policy decides file, exec, package-install and MCP operations at the syscall, while Jev can run as an optional checks provider whose verdict can only raise severity. The Jev checks layer is off by default.

Jev Tools & CLIs#community#security#ebpf

Community

ringzerosec/jev-runtime-securityRust

NucleiSniper

Scanner pipeline that fingerprints each target with 30+ signal types, then asks Jev to score every Nuclei template 0-4 for relevance so high-value checks run first while all templates still run. A tag-based prefilter keeps about 8.6% of 13,764 templates with 100% recall on score >= 3, saving ~91% of scoring tokens.

x402check

x402 risk-check provider that scores agent counterparties before payment: OFAC, phishing and drainer feeds, transaction simulation, drainer-kit fingerprints and a Jev model reading context for injected instructions, issuing an ES256-signed attestation per verdict.

Social Risk Qwen Jev

Chinese-language research project for multimodal social-risk moderation: a local Qwen3-VL-32B with language-side LoRA emits structured evidence JSON, and a fixed Jev policy turns that evidence into risk bands, with frozen test leaderboards and pure-Jev ablations.

Edward

Supervisor for unattended coding agents: it tracks cross-turn state and asks one batched Jev Choice whether a trajectory should continue, pause or escalate, while deterministic code owns dangerous-command blocking, budget caps and Ed25519-signed receipts.

jev-secret-guard

A Claude Code PreToolUse hook that blocks known key formats locally and sends only masked unknown high-entropy strings to Jev for a Noul judgment, blocking at 0.80 and asking the human from 0.30 or whenever Jev is unavailable.

BasmaAbouzied0/jev-secret-guardPython

pi-verdict

Permission gate extension for the pi coding agent: deterministic allow/deny rules and protected paths settle clear cases first, then gray-zone tool calls get one structured classify() verdict; Jev is an optional native classifier via TypeSafe direct, OpenRouter, or other gateways, failing closed on error.

Jev Tools & CLIs#community#guardrails#permissions

jesset/pi-verdictTypeScript

semcheck

Go linter whose rules are plain-English questions: AST matchers select nodes and Jev answers one Noul per fragment above the rule's threshold. It runs standalone, under go vet, and as a golangci-lint plugin, with cached answers so runs only ask about changed code.

Jev Tools & CLIs#community#linter#go

arturobermejo/semcheckGo

r2r-jev

Agent governance integration where Jev judges two Noul checks per tool call (beyond scope, destructive), an admission policy decides which judgments may become evidence, and admitted evidence degrades Trust, Delegation and Authorization in persistent R2R relation state.

approval-judge-bridge

OpenAI-compatible /v1/chat/completions proxy that answers an agent host's approval-guardian call with APPROVE, DENY or ESCALATE. Jev answers one Choice question with a calibrated distribution; missing keys, timeouts and malformed answers all fail closed to ESCALATE.

Skill Scanner

2.6k

Cisco's security scanner for agent skills added a System One analyzer: it sends the full skill text to POST /v1/systemone as one advisory Noul question and records the probability, while being deliberately unable to emit a finding or change a severity.
