Automated README summary
Automatically summarized from the README on 21 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
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.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
