construct-auto-classifier
6GitHub stars
Shell gate for coding assistants that judges commands by effect and blast radius, asking Jev twelve questions or a chat model, with fast rules first.
Jev Agents & MCP#community#awesomejev#catalog-import
Communitygodspede/construct-auto-classifierTypeScript
ego-jev-ultrafast
3GitHub stars
A single-file port of jev-ultrafast that lets Jev drive an Ego Lite browser on macOS: an in-page script indexes visible controls and one typed-choice request returns both the operation and the target index.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communityshikaizhong-design/ego-jev-ultrafastJavaScript
jev-guardrails
3GitHub stars
Mock carrier support agent with the guardrail layer built twice behind one interface: chat-model JSON judging versus TypeSafe Jev typed questions over the same 25 rules.

Communitydeepansh-saxena/jev-guardrailsPython
jev-pilot
6GitHub stars
Python helper that wraps TypeSafe Jev for agent arbitration, pre-execution guard, stuck-loop checks, fact verification and intent routing with probabilities and confidence.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityh0j5bz0adh0-stack/jev-pilotPython
typesafe-ui
7GitHub stars
Unofficial community component workspace for TypeSafe AI projects: a Turborepo and pnpm monorepo with a Next.js component browser, shiki-highlighted source previews and an interactive Lab, built on shadcn base-nova, Base UI primitives, Tailwind v4 and RTL-aware components.
Jev Integrations & Adapters#community#jevbest#catalog-import
CommunityBunsDev/typesafe-uiTypeScript
jev-shield
3GitHub stars
Proxy that sits between any MCP client and any stdio MCP server and screens tool calls, tool results and tool descriptions with Jev probabilities, layering deterministic allowlists, semantic checks and session taint tracking over a JSONL audit trail.
Jev Agents & MCP#community#jevbest#catalog-import
Communitycaiovicentino/jev-shieldJavaScript
mastra-jev-moderation
7GitHub stars
One-file Mastra input processor that screens the last user message with Jev instead of an LLM verdict: a typed yes/no gate plus a log-only category label, in a single request that fails open behind a circuit breaker.
Jev Agents & MCP#community#jevbest#catalog-import
CommunityCodeAlive-AI/mastra-jev-moderationTypeScript
typesafe-migration-guard
2GitHub stars
Next.js service with a POST /api/migration-guard endpoint that asks Jev a SAFE or DANGER choice about a SQL statement plus target environment, returning HTTP 403 to halt a CI step or HTTP 200 to let Prisma migrations proceed against Postgres.

Communityopaielsheikh/typesafe-migration-guardTypeScript
jev-shield
4GitHub stars
Manifest V3 ad blocker that scores candidate feed elements with Jev's noul primitive to collapse native ads, layered over network rules and a media engine.
Jev Demos & Experiments#community#jevbest#catalog-import
Communityvmendes90/jev-shieldTypeScript

jev-decisions
3GitHub stars
Hermes plugin that puts an agent's plans, drafts and claimed completions up for review — plan_review, evidence_review, action_verify — plus local approval rules that make no model request.
Jev Agents & MCP#community#awesomejev#catalog-import
Communitybojansandhaus/jev-decisionsPython
actiongate-jev
2GitHub stars
A runtime authorization gateway for agent tool calls: deterministic policy plus six narrow Jev questions produce evidence, then a single-use grant bound to the exact approved action is consumed at execution.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityomkarghugarkar007/actiongate-jevTypeScript
jevshield
4GitHub stars
Framework-agnostic guard layer that puts Jev in front of an agent's tool calls: a Choice risk tier, a Noul destructiveness check and a Score blast radius decide allow, deny or ask.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communitylgy1027/jevshieldPython
claude-jev-plugin

Jev Agents & MCP#community#awesomejev#catalog-import
CommunityLXBWOW/dsh-teacher-consultJavaScript
dsh-jev-decide
4GitHub stars
A DSH plugin, published to npm, that registers one agent tool, jev_decide, so a coding agent can ask TypeSafe's Jev a typed question and get a calibrated probability instead of guessing from intuition.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communitynanami-0713/dsh-jev-decideJavaScript
jev-adblock
8GitHub stars
A Chrome extension that blocks ads with no filter lists at all. Each ad-shaped element is described in a few structural fields and sent to Jev as one batched Choice question per element, with every threshold owned by code.
Jev Demos & Experiments#community#awesomejev#catalog-import
Communityfazlerocks/jev-adblockTypeScript
omp-statify
1GitHub stars
An Oh-my-pi extension that asks Jev which parts of large tool results are worth keeping before they enter the main model's context, and can also trim earlier plain-text assistant messages, keeping the original text locally for exact recovery.
Jev Agents & MCP#community#jevbest#catalog-import

Jev Tools & CLIs#community#jevbest#catalog-import
Communitym0rphtail/triagedyRust
guard-jev
1GitHub stars
A Bun and Next.js moderation demo that screens text with one systemOne call — seven hazard Nouls plus a severity Score in parallel — and computes the verdict in code from policy thresholds.
Jev Demos & Experiments#community#jevbest#catalog-import
CommunityNorbertBodziony/guard-jevTypeScript
jev-firewall
2GitHub stars
PreToolUse hook for Claude Code and Codex that puts a shell-aware rules engine and Jev in front of every tool call, returning allow, ask or block per command and logging the reason and latency behind each decision.
Jev Agents & MCP#community#awesomejev#catalog-import
CommunityKoushik890/jev-firewallTypeScript
Footwork
2GitHub stars
A computer-use agent for the browser and for native macOS apps that puts a Jev guard in front of the driver: claimed completions are checked against observed state and the trajectory, irreversible actions pass a gate, and Jev can take the mechanical steps itself.
Jev Demos & Experiments#community#awesomejev#catalog-import
CommunityTom-R-Main/FootworkPython
tweet-radar
1GitHub stars
Free Chrome extension that scores tweets already loaded on your X page against criteria you write yourself, showing the probability as a badge. The substance is the prompts library of goals, judgment subjects and counter-examples; the extension is a no-build sideload with no store listing.
Jev Demos & Experiments#community#awesomejev#catalog-import
Communitykelaocai/tweet-radarJavaScript
plotveil
1GitHub stars
PlotVeil is a Chrome extension that hides YouTube comments until a single typed Noul decision says the comment gives away the video you are on. The rule text travels from the extension to a Cloudflare Worker, which batches up to 20 comments per call and never sees the word spoiler.
Jev Demos & Experiments#community#awesomejev#catalog-import
CommunityDearest/plotveilTypeScript
jev-filter
1GitHub stars
jev-filter is a CLI that filters tool output before it reaches your agent and, since 0.3, drives web pages and desktop apps too. Jev picks the next operation and its target among controls the program enumerates itself; the program re-checks and executes, and irreversible steps stop for confirmation.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communityapixly-ai/jev-filterPython
last-exit
0GitHub stars
Last Exit is a short cyberpunk checkpoint game where you type a cover story, present a manifest and offer a bribe to an inspector who decides whether to let you through. Each reply makes two Jev calls: one turns your statements into typed observations, the other picks his next action.
Jev Demos & Experiments#community#jevbest#catalog-import
Community0x963D/last-exitJavaScript
jevegis
2GitHub stars
Jevegis wraps Jev into a single guardrail call for LLM apps: one request covering prompt injection, jailbreaks, credential and PII leaks, unauthorized actions, malicious code and indirect injection in retrieved documents, plus Trust & Safety moderation. It returns probabilities rather than booleans.
Jev Tools & CLIs#community#jevbest#catalog-import
Community0xArx/jevegisTypeScript
switchboard
1GitHub stars
An OpenAI-compatible proxy that spends one Jev call per request on injection, harm and PII checks plus a tier label, then routes to a small or large backend from pure code.
Jev Agents & MCP#community#jevbest#catalog-import
Communityaniruddh-krovvidi/switchboardPython
labs
0GitHub stars
A sparse-checkout research workspace of independent lab write-ups, two of which cover Jev: one on API behaviour, input limits and multilingual evaluation, another on moderation and pre-execution command risk checks.

Jev Tools & CLIs#community#jevbest#catalog-import
CommunityShupingR/scam-shieldTypeScript
shady-town
0GitHub stars
Social-deduction party game where the TV moderates: humans play on their phones, and one fast structured Jev judgment per round turns game state into per-player suspicion meters, with decisions and thresholds left in code.
