What is minecraft-bedrock-claude-plugin CLAUDE.md?

A set of Claude Code instructions for building Minecraft Bedrock worlds through connected tools. It explains the project structure, setup steps, commands, and how to add skills.

Use it to set up the Minecraft integration, understand the repositories and files, validate changes, and coordinate the design and construction of Minecraft structures.

It gives Claude consistent guidance for working across the Minecraft world, server, behavior pack, and connection bridge. This reduces setup mistakes and keeps changes aligned with the repository.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00590	$0.00590
Opus 5.5	$0.00236	$0.00236
Sonnet 5.5	$0.00118	$0.00118
Haiku 4.5	$0.00059	$0.00059

Security

Grade A, and why

minecraft-bedrock-claude-plugin CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Commands

node scripts/validate-plugin.mjs   # validate manifests, frontmatter, and skill/folder name alignment (Node 20+)

No build step — all files are plain markdown. Changes take effect in the next Claude Code session after the plugin is reloaded.

Architecture

This is the Claude-facing piece of a three-repository system:

Claude (Code / Desktop)
  │ MCP over Streamable HTTP
minecraft-bedrock-mcp-server        ← MCP server / bridge
  │ HTTP long-poll
minecraft-bedrock-mcp-behavior-pack ← BDS behavior pack
  │ @minecraft/server Script API
the Minecraft world

The plugin adds two things:

Guided setup — four ordered skills (connect-claude → setup-bedrock-server → setup-minecraft-world → setup-mcp-server) that walk a user through standing up the full stack.
World builder — a minecraft-builder agent that coordinates 17 skills (survey → research → plan → blueprint → build → inspect → reflect) to design and construct elements in a live world.

File structure

agents/                         ← agent steering files (.md with YAML frontmatter)
skills/<name>/SKILL.md          ← skill playbooks (.md with YAML frontmatter)
skills/<name>/references/       ← reference libraries loaded on demand (not always present)
.claude-plugin/plugin.json      ← plugin manifest
.claude-plugin/marketplace.json ← marketplace manifest
.mcp.json.example               ← reference MCP config template
scripts/validate-plugin.mjs     ← CI validation script

Adding a skill

Create skills/<kebab-name>/SKILL.md with the required YAML frontmatter (name, description, model).
The name field must exactly match the folder name.
Reference it in the relevant agent's skills: frontmatter list.
Run node scripts/validate-plugin.mjs — it catches missing/mismatched names and bad frontmatter.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
