minecraft-builder-skill

Give your agent Minecraft superpowers: it can design builds, generate JavaScript build recipes, export vanilla .nbt structures, and open interactive previews you can inspect before placing anything in-game.

Requirements

• Node.js 20.19 or newer
• npx
• An agent that can load Skills CLI skills

Setup

Install it into your agent's skills directory:

npx skills install mattzh72/minecraft-builder-skill

To target a specific agent, replace claude-code with the agent you use:

npx skills install mattzh72/minecraft-builder-skill --agent claude-code

Restart or reload your agent so it can discover the skill. On first use, the skill instructs your agent to install its Node dependencies from package.json if they are missing.

Use

Ask your agent to use the installed skill:

Use minecraft-builder-skill to make a floating crystal observatory, export the .nbt file, and open a night-mode preview.
