Safety gating
Decide whether an action is safe to run. Defence in depth, never a security boundary.
144 rows are filed under this pattern, 144 of them with code. Rows are listed as the catalogue orders them: official first, then rows with code, then by stars.
Filter and search them in the catalogue →
Rows marked “not Jev itself” or “shadow mode” stay listed, but they are not examples of deciding with Jev.

Cookbook: Classifying RAG passages
Scores each retrieved passage, then decides in code which reach the answering model — keeping contradictory ones flagged and dropping ones carrying prompt injection.
-
Cookbook: Guardrails for LLMs
Screens every message in and out of an LLM app in one request, naming hazards and scoring how much harm complying would do.
-
sub2api: Jev as a moderation endpoint
Drops in as a moderation API by asking many parallel Noul questions in one request, one per hazard category, with an anti-injection prefix on every instruction.
-
claude-code-templates: three Jev plugins
Three independently installable Claude Code plugins — guardrails, model router and skill suggestion — each with its own hooks and tests.
-
@langchain/typesafe
The JavaScript counterpart of the LangChain integration, with the same classifier and middleware shapes.
-
DeepChat: agent tool-permission review
Reviews each tool call on three axes — risk level, whether the user authorised it, and an explicit prompt-injection pressure check.
-
agentgateway: CI-validated LLM guardrail
Three Score questions on a shared severity scale, blocking the request when two or more cross the line, and failing closed.
-
atomic
Coding-agent runtime in which workflows are versioned TypeScript stages with executable checks, review gates and human approvals. Its AI package lists Jev from models.dev as a System One decision model on five providers, apart from the chat models; the README does not say where a workflow calls it.written by a model
-
Jev-cu
A computer-use agent that asks which accessibility-tree element to act on, plus a separate noul for whether the action needs explicit user confirmation.
-
mu
Coding agent and desktop app built on pi that asks Jev at 38 decision points which tool-output chunks enter the context, which stale tool results to drop, whether a rule-flagged command was asked for and whether fetched pages or MCP output carry injected instructions.
-
jev-mcp
A ready-made judgement toolbox for agents: fact verification, content screening, semantic ranking, classification and extraction as separate tools.
-
vexjoy-agent
Toolkit of 44 agents, 63 skills and 79 hooks routed from plain-English requests. Its /d router asks Jev to classify a request and gates dispatch on whether the route keeps the requested outcome; its auto-compact plugin, past 60% context, asks three nouls per unclear tool call and prunes verbatim.written by a model
-
wrongstack
Open-source coding agent with its own kernel, memory, multi-agent fleet and permission policy, run from a terminal, TUI or browser. An opt-in TypeSafe service asks Jev typed choice, noul and score questions to suggest skills and classify dispatch, and the agent can call Jev as a tool.written by a model
-
jev-gateway
Local gateway for coding agents such as Codex, Claude Code and OpenCode. Each turn it asks Jev which offered tool fits; when Jev is confident it steers the LLM to that tool, otherwise the request passes through unchanged. If Jev is down, slow or misconfigured, requests go straight to the LLM.written by a model
-
jev-drone
Camera-only simulated drone where Jev makes tactical judgements at a low rate while stabilisation and safety reflexes stay in ordinary fast code.
-
quackd
One CLI for all your robots. Connect them, command them, and let them work together, each with an LLM for a brain, Jev for cheaper steps. Microduck, Open Duck Mini, LeRobot, XLeRobot, AlohaMini, ToddlerBot or any ROS base. Claude, OpenAI, Gemini, Grok, or local via Ollama or vLLM. Simulator, .d
-
pi-jev
A decision layer for a coding agent: a measured tool-call gate plus a typed ask for calibrated answers.
-
jev-guard
Security hook for coding agents: before each tool call Jev judges how much harm it could do, whether the user asked for it and whether it follows untrusted text, and code denies, asks or allows; afterwards Jev scans the result for prompt injection. For Claude Code, Codex, Cursor and more.written by a model
-
grok-bot-jev
Router for Grok Bot that asks Jev, before research, browsing, retries or subagents, which action a request needs: reuse a cached artifact, stop a failing retry, run deterministic code, cap research, allow a subagent or ask a person. Shadow mode only logs; active mode relies on a pasted skill.written by a model
-
youtube-sponsor-detection
Chrome extension that skips YouTube sponsor reads: per 80-line transcript window, a Jev noul asks if a read starts there and a choice names the line, then nouls on short phrases place the cut; code maps lines to seconds. Audio modes ask Jev every few seconds if a read is on. Default skip bar: 70%.written by a model
-
jevals
Agent evals and guardrails as Jev questions, not an LLM judge: each eval turns a trace into nouls, choices or scores, such as a noul per claim on whether tool results back it, and a trace's evals go out as one request. The README example ran eight in 0.33 s for $0.00006. Kev or Laya run it locally.written by a model
-
bluenoise
Blur or hide noisy replies, posts & ads on X (Twitter), and clean up its interface with local, reversible keyword/account rules — no X API, no data collection, no account changes. 用本地可逆的关键词/账号规则模糊或隐藏 X（推特）上的嘈杂回复、帖子和广告，并整理界面——不调用 X API、不收集数据、不修改账号。upstream description
-
jev-kit
Claude Code kit: a PreToolUse guard where a free pre-filter passes about 93% of tool calls and Jev judges the rest (allow, warn, rewrite or block; fails open), sub-agent sizing, and Jev wired into file search, browsing and review. The author reports 9/9 browser runs at 0.0008 USD of Claude spend.written by a model

Jev-Moderation-Bot
