hytale-mod

hytale-mod is a skill for Claude Code from ZacxDev/claude-hytale-mod. It costs 35 tokens per session (5,558 once invoked), scanned A, original, MIT.

A development guide for creating Hytale server plugins and mods in Java. Hytale is a game, and its server can be extended with commands, events, custom interfaces, and new assets.

In plain words
What is it for?
Use it to build Java 25 Hytale plugins with Gradle Groovy, including commands, events, custom UI, asset packs, items, weapons, and animations.
Why use it?
It gives the project the required Java and Gradle setup, dependency coordinates, repository settings, and expected file layout. This avoids guessing at the build requirements for Hytale’s early-access server.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./server/start.sh.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

Security

Grade A, and why

hytale-mod 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.

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.

Hytale Modding Skill

Prime context for Hytale server plugin development and modding (Early Access, Dec 2025).

Environment Requirements

  • Java 25 (required by Hytale server)
  • Gradle Groovy DSL only — Kotlin DSL (.gradle.kts) fails with JDK 25
  • Maven coordinates: com.hypixel.hytale:Server:2026.01.28-87d03be09

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.
