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 | $0.00066 | $0.04307 |
| Opus 5 | $0.00033 | $0.02153 |
| Sonnet 5 | $0.00013 | $0.00861 |
| Haiku 4.5 | $0.00007 | $0.00431 |
Grade A, and why
minecraft-modding 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 3d 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.

Minecraft Modding Skill
Overview
This skill guides Codex through developing open-source Minecraft mods. Target platforms:
| Platform | MC Version | Java | Build System |
|---|---|---|---|
| NeoForge | 26.x current; 1.21.11 examples retained | Java 25 current; Java 21 on 1.21.x | Gradle + ModDevGradle |
| Forge | 1.20.1 legacy lane | Java 17 | Gradle + ForgeGradle 6 |
| Fabric | 26.x current; 1.21.11 examples retained | Java 25 current; Java 21 on 1.21.x | Gradle + Fabric Loom |
| Architectury (multiloader) | 26.x or 1.21.x | Match Minecraft | Gradle + Architectury Loom |
Always confirm the platform and Minecraft version from gradle.properties or build.gradle
before writing any mod-specific code.
Minecraft 26.1 introduced Java 25 and unobfuscated game executables. For 26.x projects, start from the current loader generator or example mod and preserve its build layout. Do not copy the 1.21.11 mapping, Loom plugin, remapping task, or Java 21 snippets in this skill into a 26.x project. Fabric 26.x uses the non-remapping Loom path and official names; NeoForge 26.x should start from the current NeoForge generator. Treat the detailed API references here as the legacy 1.21.x lane unless a section explicitly says 26.x.
Routing Boundaries
Use when: the task is Java/Kotlin mod code, registry/event work, networking, datagen wiring, and loader APIs.Do not use when: the task is command-only vanilla logic (minecraft-commands-scripting) or pure datapacks (minecraft-datapack).Do not use when: the task targets Paper/Bukkit plugins (minecraft-plugin-dev).
1. Identifying the Platform
# NeoForge project signature
grep -r "net.neoforged" gradle.properties build.gradle settings.gradle 2>/dev/null | head -5
# Forge 1.20.1 project signature
grep -r "net.minecraftforge" gradle.properties build.gradle settings.gradle 2>/dev/null | head -5
# Fabric project signature
grep -r "fabric" gradle.properties build.gradle settings.gradle 2>/dev/null | head -5
# Read mod ID and version
cat gradle.properties
What ships with it
5 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.
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.

minecraft-modding is a skill published in the GitHub repository Jahrome907/minecraft-agent-skills (135 stars, last pushed 4d ago), licensed MIT. It adds 66 tokens to every session and 4,307 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
