01 — Your World
Keep the world. Add the agent.
The pack adds a companion entity and a local reasoning bridge. It does not replace terrain, require a starter map, or upload your world save.
Move with purpose
Follow the nearest player or navigate toward a validated nearby position.
Gather safely
Find and break nearby natural resources from an explicit, protected allowlist.
Return later
Names, goals, pause state, and recent status are saved with the world.
02 — How It Works
Reasoning outside. Control inside.
The model proposes one bounded action. The mod decides whether it is safe and possible before Minecraft changes anything.
Minecraft worldShares a small structured observation—not the entire save.01
Local Agent HostKeeps credentials in memory, applies rate limits, and asks the model for one action.02
Validated actionAccepts only a strict action vocabulary with bounded messages and coordinates.03
Fabric executorChecks distance, path, resource allowlist, and world state before execution.04

Block entities and protected blocks are excluded
Pause, resume, inspect, and remove controls stay with the player
The Agent Host binds only to your local computer
