minecraft-agent-skills: Skill for Claude Code

.agents/skills/minecraft-multiloader/SKILL.md

minecraft-multiloader is a skill for Claude Code, Codex from Jahrome907/minecraft-agent-skills. It costs 53 tokens per session (2,965 once invoked), scanned A, original, MIT.

A development guide for Architectury, a Minecraft framework that lets one codebase produce mods for both NeoForge and Fabric, two mod-loading platforms.

In plain words
What is it for?
Use it when building or maintaining a Minecraft mod that must ship for both NeoForge and Fabric.
Why use it?
It explains how to share common code while keeping platform-specific parts separate, instead of maintaining two unrelated projects.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is Jahrome907/minecraft-agent-skills's own configuration. It tells Claude Code and Codex how to work on minecraft-agent-skills itself, so it is not a mod to install elsewhere.

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.

Fable 5.1 $0.00053 $0.02965
Opus 5.5 $0.00021 $0.01186

Security

Grade A, and why

minecraft-multiloader 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-version-sanity.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Minecraft Multiloader Skill (Architectury)

What Is Architectury?

Architectury is a framework that lets you write one mod codebase that compiles to both NeoForge and Fabric JARs. The common subproject has a shared API; platform subprojects implement platform-specific behavior behind the @ExpectPlatform abstraction.

Routing Boundaries

  • Use when: one shared codebase must build and ship both NeoForge and Fabric artifacts.
  • Do not use when: the project is single-loader only (minecraft-modding for NeoForge/Fabric, not both).
  • Do not use when: the task is Paper/Bukkit plugin development (minecraft-plugin-dev).
Component Purpose
architectury-loom Gradle plugin — extends Fabric Loom for multiloader support
architectury-api Runtime library — abstractions over both platforms
@ExpectPlatform Annotation marking methods with platform-specific implementations
common/ Shared code (no loader-specific APIs)
fabric/ Fabric-specific code + entrypoint
neoforge/ NeoForge-specific code + entrypoint

Versions (Minecraft 1.21.11)

# gradle.properties property names used by this skill's static helper.
# Get every tool version from the exact generated or known-working project.
mod_version=1.0.0
minecraft_version=1.21.11
enabled_platforms=fabric,neoforge

architectury_version=<project pin>
fabric_loader_version=<project pin>
fabric_api_version=<project pin ending in +1.21.11>
neoforge_version=<project pin in the 21.11.x family>
loom_version=<project pin>

Pin architectury_version, the Architectury plugin version, and loom_version from the same generated or known-working project line. This skill deliberately does not publish a copyable dependency matrix: its static helper cannot resolve whether a particular set of versions is compatible.

For Minecraft 26.x / Java 25, use the official Architectury Template Generator only when its version selector offers the exact target. Generate a Multiplatform project with Fabric and NeoForge, then preserve the generated Gradle layout and pins as one set. If the generator does not offer the target, begin with an already working project on that exact line and inspect its resolved build; do not relabel a 1.21.11 template as 26.x. The published template downloads are not a substitute for an exact-current scaffold.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
