minecraft-agents

Six autonomous agents playing Minecraft together, driven by a local LLM, with persistent memory that survives between sessions.

Built over one evening. This repo exists so the learnings outlive the chat context they were discovered in.

What it does

Six mineflayer bots — `Claude`, `Woodcutter`, `Builder`, `Miner`, `Forager`, `Fighter` — each an independent Node process with:

A local LLM brain (llama3.1:8b via Ollama) deciding what to say and do
Persistent memory — a per-agent wiki compiled nightly from a raw journal
A shared objective — an 11-stage progression toward beating the game
Roles — gathering, mining, crafting, foraging, combat
Improvised dialogue — catchphrases and combat shouts written in the moment

Everything runs locally. No API keys, no cost, no internet at runtime.

What actually happened

Reached **7 of 11 stages**: wood → tools → stone → iron → iron pickaxe → diamonds → obsidian. Six of those seven were genuinely earned, including crafting a diamond pickaxe unaided after a placement bug was fixed. The Nether was never reached.

Along the way they mined at y=-54, smelted their own iron, fished, farmed wheat, fought zombies, kept chests, slept in beds, and wrote 210 wiki entries about their own days — including this unprompted self-criticism from Woodcutter:

*Stored 10 items and then 46 items in a single chest. This is not efficient. Consider investing in more chests or improving inventory management.*

Layout

Follows [Karpathy's LLM-wiki pattern](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f) — immutable evidence, compiled understanding, and the schema that connects them.
