• jev-auto-approve

  metalbear-co · Security & Guardrails

  Jev is a decision model: it answers a typed question with a calibrated probability rather than prose. This action asks it one yes/no question per thing worth being sure about — answered in parallel in a single call — and approves only when every one of them clears your threshold:

• pi-jev-guard

  Reindeer-AI · Security & Guardrails

  Check Pi code edits against repository Markdown rules with TypeSafe Jev

• jev-model-tokengate

• jev-phishing-bench

  anisselbd · Security & Guardrails

  The signal result above was challenged on three points: no non-AI baseline, selection and evaluation on the same emails, and no equivalent decomposition for the LLM. Three controls were added (`bench/heuristics.py`, `bench/protocol.py`, `run_llm_signals.py`); nothing above was changed. Full tables in `results/report.md`, chart in `results/controls.png`.

  **Open-source AI agent monitoring, malicious-agent detection, and escalate-only containment** for sandboxed LLM agents. Local HackSpain 2026 stack (AngryRobot dashboard): FastAPI, React/Vite, Neo4j. Classifies a *chain of actions*, not a single tool call. A model never pulls the plug.

• claude-jev-warden

  Real-time quality gate and Art Director Warden for Claude Code powered by TypeSafe Jev 1.13 non-autoregressive decision model

• jevals

  1. Open any website. 2. Click the Jev icon. The side panel opens on **Drive**. 3. Type a goal, e.g. *Search Wikipedia for "espresso" and open the article*, and press **Run**.

• jev-engineering

  codejunkie99 · Security & Guardrails

• reflex

  kaustav1996 · Security & Guardrails

  A coding agent and personal assistant built on the Pi coding agent. Jev checks every tool call, turn and voice transcript, and code decides what happens next: allow, ask or block an action, which model tier to use, and whether a "done" was actually verified.

• JevPR

  HexyeDEV · Security & Guardrails

  PR Risk review, automated by Jev

• guardrail-chatbot-jev

  taman-spirit · Security & Guardrails

  It is a library, not a service. You call it, you get a verdict, and your code decides what to do. It runs in **Python and TypeScript**, both reading the same policy file, so the two sides of your stack cannot drift apart. Neither package has a third-party dependency.

• jev-reasoning-navigator

  AndreuVM · Security & Guardrails

  En lugar de depender de heurísticas matemáticas frágiles o distancias vectoriales locales de coseno, `JEV-Reasoning-Navigator` utiliza **TypeSafe AI (`typesafe-sdk`)** como motor único y autoritativo de decisión cognitiva:

• jev-kit

• jev-enforce

  erkamyaman · Security & Guardrails

  📏 Claude Code plugin that makes Claude follow your CLAUDE.md: every reply and edit checked by TypeSafe Jev ✅

• grok-jev-guard

  0xwhrari · Security & Guardrails

  `grok-jev-guard` sits immediately before a meaningful Grok Bot tool sequence. It receives a compact description of the pending operation and returns one explicit action:

• dsh-jev-verify

  xienda · Security & Guardrails

  Jev (TypeSafe System One) decision tools + live verification benchmark for DeepSeek Harness: jev_decision (choice/score/noul) and jev_verify, honest by design.

• opencode-jev-guard

  CogFlux · Security & Guardrails

  When FarHand is active, the agent's commands run on a remote host through the `farhand_remote_shell` MCP tool instead of `shell`. OpenCode's permission request for an MCP tool carries no arguments, so the plugin takes the command (and its `cwd`) from the `execute.before` hook, which OpenCode runs first.

• momus-review

  brianluby · Security & Guardrails

  Code review on rust and javascript (+languages soon) applications. Following lenses correctness, security, reliability, compatibility and testGap.

• jev-engineering

  eugeniughelbur · Security & Guardrails

  A Claude Code tool-call gate. Clearly safe commands run with no permission prompt, clearly dangerous ones are blocked with the reason, and unclear ones get the normal prompt. Also ships review-router, a GitHub Action that routes AI code review to a full or quick read. Disclosure: I built and maintain it.

• building-with-typesafe-jev

  aaddrick · Security & Guardrails

  Unofficial skill that teaches coding agents to build with TypeSafe AI's Jev: typed decisions, calibrated confidence, and prior art from 150+ community projects.

• jev-baselines-eval

  ickma2311 · Security & Guardrails

  Every latency number here is **wall-clock duration of one API call** measured in the client: a timestamp before the request, another after the full response body is read ([`code/run_b1.py:32`](code/run_b1.py), [`code/common.py:50`](code/common.py)). Non-streaming on both sides, so these are completion times, not time-to-first-token.

• jev-test

  cgbarlow · Security & Guardrails

  Prototype: AI-assisted NZQA marking from rubric criteria alone, using TypeSafe Jev for guardrails, criterion scores and confidence-based triage. NOT ENDORSED BY NZQA - CONCEPT ONLY

• laya-browser-guard

  pateti-hub · Security & Guardrails

  A passive, privacy-first Chrome security copilot that combines deterministic browser-visible checks with local Laya and official Jev typed decisions. It evaluates redacted evidence from scripts, resources, forms, headers, and DOM signals, then explains investigation priority without attacking the target.

• medula

  JoaquinRuiz · Security & Guardrails

  Suggesting Médula for the coding-agents domain. I'm the author.

• pi-jev-eye

  bismawy · Security & Guardrails
