.agents/skills/minecraft-server-admin/SKILL.md

minecraft-server-admin is a skill for Claude Code, Codex from Jahrome907/minecraft-agent-skills. It costs 61 tokens per session (3,461 once invoked), scanned A, original, MIT.

An operations guide for Minecraft Java servers, including server software, proxies, backups, performance tuning, security, and incident recovery. It covers current 26.x releases and older 1.21.x releases across several server platforms.

In plain words
What is it for?
Deploying and upgrading servers, configuring Paper, Purpur, Folia, Velocity, Fabric, or NeoForge, managing backups and proxies, tuning performance, and responding to incidents.
Why use it?
It helps server operators choose a suitable setup and troubleshoot live infrastructure without confusing server administration with plugin or mod development.

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.

Security

Grade A, and why

minecraft-server-admin 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 Server Administration Skill

Scope and Routing Boundaries

Routing Boundaries

  • Use when: the task is infrastructure or live operations for Minecraft servers (deployment choice, tuning, backups, proxying, security, incident response).
  • Do not use when: the task is writing plugin code (minecraft-plugin-dev) or writing mods/loaders (minecraft-modding, minecraft-multiloader).
  • Do not use when: the task is WorldEdit command workflows (minecraft-worldedit-ops) or EssentialsX workflow/policy design (minecraft-essentials-ops).
  • Do not use when: the task is datapack/resource-pack authoring (minecraft-datapack, minecraft-resource-pack).

Support Assets

  • Read references/deployment-checklists.md when the task is an incident, rollout window, proxy change, or recovery drill and you need a compact checklist before acting.

Deployment Decision Matrix

Use this table when choosing a deployment. For an existing server, inspect its stack and version first and preserve them unless migration is requested.

Deployment profile Recommended stack Pick this when Watch-outs
Small SMP on Paper Paper only Up to ~30 concurrent players, broad plugin compatibility, low ops overhead Do not over-tune early; profile before changing many defaults
Larger public Paper server Paper + Spark + stricter plugin/change control Public server with frequent joins, moderate plugin set, uptime matters Plugin sprawl is the top TPS risk
Velocity-backed network Velocity + multiple Paper backends Hub/minigame/factions split across servers, need shared entrypoint Forwarding/auth mismatches can block joins
Purpur gameplay-heavy server Purpur (optionally behind Velocity) You want gameplay knobs exposed in config without custom plugin code Extra toggles increase misconfiguration risk
Folia high-concurrency server Folia + Folia-compatible plugins only Very high concurrency with region-threading goals Many plugins are not Folia-safe
Fabric/NeoForge mod server Fabric or NeoForge server build You require loader mods, custom content, modpack behavior Bukkit/Paper plugins do not apply

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.
