What it is

A RuneBench fork that lets TypeSafe's Jev, a non-generative model, play RuneScape through a bounded action catalog built on rs-sdk. It records tick-level results and provides a live dashboard for developers and benchmarkers.

How it uses Jev

Jev answers typed questions (choice, noul, score) with calibrated probabilities. In tick mode, each poll asks next_action (current or another catalog action) and this_tick (do_nothing, close_dialog, eat_food, restart_current). Jev also answers poll_again_in_ticks. Code executes the chosen action and reports game state.

Technique worth stealing

Bounded action catalog with tick-mode polling; Jev decides, code executes.

Try it

Run agents/jev/live-stack.sh up ../rs-sdk --skill Fishing --minutes 30 --policy jev --bot skyvern --speed 1 --xprate 1 --mode tick --poll-every 3
