ArturSkowronski/kNES

Gaming: a Kotlin NES emulator whose agent plays Super Mario Bros. and Final Fantasy through SemIf, the open implementation of the Jev interface, on a local Qwen3.5-4B reading the screen itself; the goals that apply this turn become the declared options of one typed `Choice`, so a button the game does not offer is impossible rather than unlikely, and 900 logged decisions at ~400 ms each on an M5 Pro never once answered off the menu.

What Jev does in kNES

The project describes itself this way: Gaming: a Kotlin NES emulator whose agent plays Super Mario Bros. and Final Fantasy through SemIf, the open implementation of the Jev interface, on a local Qwen3.5-4B reading the screen itself; the goals that apply this turn become the declared options of one typed `Choice`, so a button the game does not offer is impossible rather than unlikely, and 900 logged decisions at ~400 ms each on an M5 Pro never once answered off the menu. In the Community additions category, Jev typically decides a single well-defined judgment, such as a label, a score or a yes/no check.

Verification

Verified. We confirmed this repository and its Jev relevance through the GitHub API and the source lists below. A specific file link has not been recorded yet.

How Community additions projects use Jev

Projects added from community lists and direct submissions. Many are small, single-purpose experiments, which makes them some of the easiest places to see how a Jev question is framed in real code.

  1. Jeviewandududu/jeviewLocal gateway and live map of every Jev call your code makes, in one dependency-free file. It holds the key itself: a caller's own bearer token is dropped rather than forwarded, and with no key set it will not proxy at all.★ 34

  3. BTC 5m Decision Labfrankda/jev-poly-crypto-demoResearch tool for Polymarket's BTC 5-minute markets: Jev scores the direction, separate code decides the entry, and any TRADING_MODE other than paper throws at startup. No licence file.★ 35

  4. RoboJEVlykycy123/RoboJEVRobotics simulation: uses two-stage Jev `Choice` decisions over structured state to select intent and Cartesian motion/gripper commands for a Franka Panda in MuJoCo, rejecting malformed responses and checking task success independently through physics.★ 33
    Python
  5. jeff (Alurith)Alurith/jeffRead-only Go CLI that checks files against rules such as unclear responsibility or weak error handling with Jev, locally or in CI.★ 36
