10 open-source projects built on the Jev API
A checklist of 10 real open-source projects using Jev, from a StarCraft bot and a browser extension to PR risk routing and prompt injection defense.
Jev is everywhere on the timeline right now. If you already got your Jev API key but don't know what to build with it first, just steal this checklist: 1. tsai-sc Jev plays the original StarCraft through keyboard and mouse, with the action probabilities recorded for every decision it makes. https://github.com/phyous/tsai-sc 2. unclutter Browser extension that asks Jev whether each element on a page is clutter, then removes it under reusable template rules. https://github.com/kitze/unclutter 3. jev-bfs Finds link paths between Wikipedia articles. Jev ranks each page's outgoing links, plain Python controls the search. https://github.com/komikat/jev-bfs 4. jevql Run plain SQL on vanilla Postgres, then ask Jev Noul, Choice or Score questions about every row that survives. No extension needed. https://github.com/kylemclaren/jevql 5. limpet A Stop hook that keeps your coding agent from finishing too early by judging plain-language completion rules with Jev. https://github.com/noplan-inc/limpet 6. DiffJury Routes every pull request by risk with Jev before a human reviewer is assigned, and doubles as a review coach. https://github.com/raihankhan-rk/diffjury 7. jev-guard Prompt-injection and dangerous-action guard for Claude Code, Codex and Pi agents, with Jev deciding what gets blocked. https://github.com/leepokai/jev-guard 8. Sniff Test A prose linter: ten yes-or-no questions per paragraph for stacked hedges, restating closers and other writing tics. CLI, pre-commit hook and GitHub Action. https://github.com/DanRWilloughby/snifftest 9. jevcal Fits a confidence threshold per question on your own labelled data, verifies it on a held-out split, and fails CI when a model update breaks it. https://github.com/abhixhek/jevcal 10. Jev Moderation Bot Discord bot that scores incoming messages for phishing, spam and social engineering with Jev and drives a four-stage escalation ladder. https://github.com/brainstormity/Jev-Moderation-Bot Copy these complete Jev blueprints - then read full Jev setup below ↓ ↓
