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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00035 | $0.05558 |
| Opus 5 | $0.00017 | $0.02779 |
| Sonnet 5 | $0.00007 | $0.01112 |
| Haiku 4.5 | $0.00003 | $0.00556 |
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.
How it starts
The opening of the file, as written. The whole thing — 676 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

hytale-mod is a skill published in the GitHub repository ZacxDev/claude-hytale-mod (4 stars, last pushed 7mo ago), licensed MIT. It adds 35 tokens to every session and 5,558 once invoked, about $0.0002 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 2026-08-31.
