What it is
An autonomous Minecraft Java 1.16.5 agent for Survival/Peaceful speedruns. Astra (GPT-6 or GPT-5.6) sets objectives and waypoints; Jev picks one bounded action per step. Includes native recording, route data, and tests.
How it uses Jev
Jev selects one available action from current game observations: travel, mining one block, collecting a drop, crafting, opening a chest, eating, sleeping, or combat interactions. The planner sets the objective, item targets, and travel waypoint. Mineflayer executes the chosen action via the normal player protocol.
Primitives:choice
Technique worth stealing
Structured-state control: Jev chooses from a small legal action set over game observations, not screenshots or key presses.
Try it
npm install; start server.jar; run freeze-run.mjs then nether-agent.mjs with NATIVE_VIEW=1; launch native-client/launch.py.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
