10 open source repos run Jev decision loops across 5 domains
The author collects 10 open source projects showing how Jev makes only millisecond-level structured judgments while code handles execution, spanning desktop control, games, drones, trading and other domains.
Jev doesn't write text. It runs one loop: read structured state, judge one decision in milliseconds, hand it to code. Most people with API access still test it like a chatbot, while the builders getting results run that loop. Here are 10 open source repos running that exact loop across 5 domains. agent-desktop Reads your desktop's accessibility tree and judges which button, menu or field to hit next. https://github.com/lahfir/agent-desktop typesafe-mario Jev plays Super Mario with zero screenshots. It reads game state straight from emulator RAM and decides: run, jump or dodge. https://github.com/fhshaik/typesafe-mario jev-drone Flight control still owns stability and safety. Jev only makes the high level calls: climb, brake, steer around obstacles. https://github.com/RomanSlack/jev-drone OneVOneJev A 1v1 shooter in the browser. Every tick, Jev judges movement, aim, fire and jump. https://github.com/emrickgarrett/OneVOneJev jev-trader High frequency market making on Monad testnet. Jev reads spreads and trade flow, then picks the next buy or sell in about 81ms. https://github.com/jarrodwatts/jev-trader Prism Jev never places an order here. It reads toxic flow, market pressure and mean reversion, then hands control back to your existing strategy. https://github.com/irfndi/prism-liquidity-agent neo4jev Jev walks a knowledge graph. At every node it picks the most valuable edge and follows it to the end. https://github.com/jexp/neo4jev jev-curate Screens JSONL and Parquet training data for quality, relevance and risk before anything enters the next training run. https://github.com/AkashPriyadarshii/jev-curate Canny Stops coding agents from claiming they're done when they aren't. Jev checks tool output, diffs and tests, then rules on the claim. https://github.com/qkal/Canny killmyidea Paste a startup idea. Jev scores it from several angles and returns one verdict: KILL, FIX or SHIP. https://github.com/monteduro/killmyidea Same pattern in all 10: structured state in, one decision out, code does the rest. These are community projects, not audited production code. Read the source before you connect keys or real money. Copy the blueprints, then read the full Jev setup below ↓
