Real Jev Agent Implementations
Live demonstrations, open-source repositories, and sourced benchmarks where developers put Jev into production loops. Filter by architecture pattern or explore video breakdowns below.
Jev Browser
A Jev-driven browser agent exposed as an MCP server, CLI, or library.
TypeSafe Agent Skills
Official skills that teach coding agents how to design and compose TypeSafe decision workflows.
Jev MCP
Ten typed Jev judgment tools for verify, screen, find, rerank, classify, decide, compare, extract, review, and gate.
CUA-S1 Form Automation
An open 706k-parameter System 1 model specialized for mapping user data into web form inputs in 50ms.
Mastra Agent Guardrail Middleware
A single-file drop-in middleware for Mastra agent workflows that screens prompts and tool parameters in ~400ms.
Pi-Heed Tool Call Auditor
An agent security supervisor that audits side-effecting tool calls against the user's explicit request.
Jev Skill Router
A fast semantic dispatcher that selects the right agent skill from large catalogs without prompt bloating.
Firehose Stream Judge
Filters live social firehoses post-by-post at $0.00003 per item, triaging high-value signals for deep analysis.
Jev-RA Reactive Browser Agent
A fast browser automation loop where Jev decides the next interaction in ~300ms.
Pi Context Curator
An active memory curator that scores and prunes agent working context to prevent context drift and bloat.
RouteKit Complexity Router
Classifies task complexity in milliseconds to route between small utility models and frontier reasoning agents.
Skillbox Tool Matcher
A self-hosted agent skills library with Jev-powered semantic recommendation and tool catalog routing.
@gregpr07
Flight Search with Browser Use
A browser agent searching real-world flights at 1× speed with Jev choosing each next action.
Jev Ultrafast
Browser Use's open-source ultra-fast browser agent harness powered by Jev decisions.
@awlevin
TypeSafe Computer Use
Open-source macOS desktop control loop with bounded Jev decisions at every single step.
@manofsteel3129
AskJev (MCP Agent)
Claude handles conversational intent while Jev directs browser navigation across live websites.
@instructa
Switchloom
Deterministic model routing for coding agents, featuring an installable skill for Codex.
Jev Harness Router
One batched Jev call selects model tier, tools, skill, and effort level for each turn.
@jackbarunz
Jev Tool Router
Selects the exact MCP tool for Codex to prevent tool overload and context degradation.
Jev Tool Runner
Jev selects developer tools while Codex writes code, creating a clean separation of roles.
SkillRanker (Rust CLI)
A high-performance Rust CLI where Jev ranks available agent skills for the next action.
Jev MCP Dispatcher
Executes plain-language MCP tool calls with zero general LLMs, driven entirely by Jev.
@clownware
Bouncer
A judgment layer checking every Claude Code tool call against customizable organizational policies.
Compact Adviser
Evaluates active agent context windows and signals the optimal moment to perform conversation compaction.
Codex Context Diet
A Codex plugin where Jev trims bulky tool results before they pollute the agent context window.
Jev Router (Skill)
A dual Claude Code and Codex skill that automatically picks the right model for any prompt.
Jev Review Action
A lightweight GitHub Action that reviews, labels, and classifies pull requests with Jev alone.
Jev MCP Coding Loop
An MCP server placing Jev directly on the inner coding loop in Cursor, Claude Code, and Codex.

we built blazing fast computer/browser use with Jev + @Stagehanddev.
@jarrodwatts
jev-trader
I built a trading bot with Jev!
@jasonlu_ai
jev-e2e
JEV is changes the world of E2E testing!

Just trying out Jev, I made a Chrome extension that:
LogJev
An open-source Jev-style decision layer that accepts text, images, or audio and returns bounded choices or scores.
Token Saver
A Codex workflow that delegates bounded work and uses Jev Context to select relevant source excerpts before the main agent reads them.
fast-jev-codex
A Codex plugin that scores tool history and restores verbatim context after compaction.
Jev Codex Router
Routes coding prompts to Luna, Sol, or Astra with an appropriate reasoning level.
Jev Classifier
A tool-selection layer for Codex and Claude Code that filters the available tools before expensive model calls.
NewsJack
A news-intelligence workflow that uses Jev to triage stories before expensive brand-specific synthesis.
Jev System Architect
A coding-agent skill for finding places where fuzzy semantic logic should become an explicit Jev decision boundary.
Jev Benchmark
A community benchmark project for testing Jev as a guardrail over risky agent tool calls.
JevBenchmarkLab
An open benchmark harness for testing Jev decision consistency, adversarial failures, option-order bias, and latency.
