SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires jq, node, and includes scripts (resource) components.

What problem does it solve?

This Skill helps you create, validate, and troubleshoot custom Minecraft world generation without manually tracing every biome, feature, dimension, and structure reference.

Core Features & Use Cases

  • Custom world generation design: Plan biomes, dimensions, noise settings, surface rules, configured features, placed features, carvers, structure sets, and processor lists for Minecraft 1.21.x.
  • Datapack and mod workflows: Use JSON-only worldgen for vanilla-compatible packs or code-driven registration for NeoForge and Fabric projects.
  • Validation and routing: Check worldgen JSON for broken links, place features in the correct generation step, and distinguish when to use biome modifiers versus full biome replacement.
  • Use case: A server owner wants a new ore vein, a custom biome, and a structure spread across the overworld, and this Skill provides the files, placement rules, and validation steps needed to ship it safely.

Quick Start

Use the minecraft-world-generation skill to design and validate a custom biome, dimension, structure, or feature setup for Minecraft 1.21.x.

Frequently Asked Questions about minecraft-world-generation

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate custom Minecraft worldgen JSON for broken references?▼

Minecraft worldgen validation checks cross-reference integrity across datapack and mod resource files, catching broken links in custom biomes, dimensions, placed features, and structure sets for Minecraft 1.21.x.

Does Minecraft 1.21.x worldgen support both datapack and NeoForge workflows?▼

Yes, Minecraft 1.21.x worldgen supports JSON-only datapack workflows for vanilla-compatible packs alongside code-driven registration paths for NeoForge and Fabric mod projects.

How do I add a custom ore vein and structure to a Minecraft biome?▼

To add a custom ore vein and structure, generate the required worldgen JSON files, apply correct placement rules for the generation step, and validate biome modifiers versus full biome replacement.

When do I use biome modifiers instead of full biome replacement in NeoForge?▼

Use NeoForge biome modifiers for targeted additions like inserting ores or structures, whereas full biome replacement is necessary when overhauling entire surface rules, noise settings, and generation defaults.

What does a placed feature validation check in Minecraft datapacks?▼

Placed feature validation verifies that feature placement JSON targets the correct generation step and ensures cross-references to configured features remain intact within the Minecraft 1.21.x datapack structure.

Why is my custom Minecraft dimension not generating correctly?▼

Custom Minecraft dimension generation fails when worldgen JSON contains broken references in noise settings, biome links, or structure sets, requiring cross-reference validation to identify and resolve the routing errors.
