SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill removes the guesswork and boilerplate involved in Minecraft mod development by guiding the full workflow from platform detection and registry setup to assets, recipes, data generation, and testing.

Core Features & Use Cases

  • Platform-aware mod authoring: Handles NeoForge, Fabric, and multiloader Architectury projects with the correct entry points, registries, and event patterns.
  • Feature implementation: Creates and updates blocks, items, entities, GUIs, networking, commands, and worldgen data with matching JSON assets.
  • Build and release support: Helps validate Java 21, run Gradle builds and game tests, and keep generated files aligned with code changes.
  • Use case: A developer can ask for a new block, a custom item, or a cross-loader migration and get coordinated code, resource files, and build-ready instructions.

Quick Start

Ask the skill to add or fix a Minecraft mod feature for your NeoForge or Fabric project and include the target Minecraft version, platform, and desired behavior.

Frequently Asked Questions about minecraft-modding

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

FAQPage Schema
How do I add a custom block or item to a NeoForge Minecraft mod?

To add a custom block or item to a NeoForge Minecraft mod, you define the registry entry and implement the logic. This workflow generates the Java code and matching JSON resource files for reliable, build-ready mod features.

What is the best way to migrate a Minecraft mod from Fabric to NeoForge?

Migrating a Minecraft mod from Fabric to NeoForge involves adapting the entry points, registries, and event patterns. Cross-loader migration provides coordinated platform-specific code to ensure the build functions correctly on the target platform.

Do I need Java 21 and Gradle to build Minecraft mods with Fabric or NeoForge?

Yes, you need Java 21 and a Gradle-based project structure to build Minecraft mods reliably. Validating the Java version and running Gradle builds are required steps for successful mod compilation and game testing.

Can I develop multiloader Minecraft mods using Architectury?

Yes, you can develop multiloader Minecraft mods using Architectury. This approach manages multiloader projects by applying correct entry points and platform-specific API patterns for both NeoForge and Fabric simultaneously.

How does datagen work for generating Minecraft mod assets and recipes?

Datagen for Minecraft mod assets and recipes works by automatically generating matching JSON resource files from your code definitions. This ensures data generation remains aligned with code changes during the build workflow.

Why does my Minecraft mod build fail after updating registry entries?

A Minecraft mod build might fail after updating registry entries if the generated JSON resource files are not aligned with the new code changes. Running Gradle builds and datagen validates the platform-specific API patterns to fix the workflow.
