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 | $0.00057 | $0.03567 |
| Opus 5 | $0.00028 | $0.01784 |
| Sonnet 5 | $0.00011 | $0.00713 |
| Haiku 4.5 | $0.00006 | $0.00357 |
Grade A, and why
minecraft-testing 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 2d 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 Testing Skill
Testing Strategies Overview
| Approach | Best For | Requires Game? |
|---|---|---|
| JUnit 5 (pure unit tests) | Logic, data structures, NBT serialization | No |
| MockBukkit | Bukkit/Paper plugin events, commands, inventory | No (mocked server) |
| NeoForge GameTests | In-game block/entity/world interaction | Yes (test environment) |
| Fabric GameTests | In-game block/entity/world interaction | Yes (test environment) |
| Integration server | Full plugin/mod lifecycle | Yes (dedicated test server) |
Use Java 25 for current 26.x projects. Keep legacy 1.21.x examples on Java 21 and Forge 1.20.1 on Java 17. Do not combine source layouts or APIs across lanes.
Routing Boundaries
Use when: the task is designing or implementing automated tests (unit, mock, gametest, CI test jobs) for Minecraft projects.Do not use when: the task is implementing gameplay features rather than testing them (minecraft-modding,minecraft-plugin-dev,minecraft-datapack).Do not use when: the task is release automation or publishing pipelines (minecraft-ci-release).
Bundled References And Helpers
- Layout guide:
references/test-layouts.md - Fixture/layout validator:
./scripts/validate-test-layout.sh --root <project>
Use the validator before copying a test layout into a real project. It checks visible static dependencies, metadata, and literal structure references. It does not compile the project or prove a Game Test can run.
Unit Testing (JUnit 5 — No Minecraft)
JUnit Platform task
tasks.test {
useJUnitPlatform()
testLogging {
events("passed", "skipped", "failed")
}
}
For Fabric code that needs loader setup, use Fabric Loader JUnit rather than assuming ordinary JUnit initialized Minecraft:
dependencies {
testImplementation "net.fabricmc:fabric-loader-junit:${project.loader_version}"
}
test {
useJUnitPlatform()
}
What ships with it
2 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-testing is a skill published in the GitHub repository Jahrome907/minecraft-agent-skills (132 stars, last pushed 3d ago), licensed MIT. It adds 57 tokens to every session and 3,567 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.
