audit-config

audit-config is a skill for Claude Code from Teddy563/mcwrench. It costs 171 tokens per session (1,231 once invoked), scanned A, original, MIT.

A review tool for Minecraft server configuration files. It checks settings across the server and its worlds for performance problems, security risks, and common setup mistakes.

In plain words
What is it for?
Use it to inspect Paper, Spigot, Purpur, or Velocity server settings, including proxy connections, player forwarding, view distances, and plugin configuration.
Why use it?
Minecraft servers often use several configuration files whose settings can conflict or quietly override one another. This produces a ranked list of fixes instead of requiring a manual file-by-file review.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

audit-config 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.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/check-conflicts.mjs, scripts/diff-against-defaults.mjs, scripts/scan-server-tree.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Audit Config

Scan a Minecraft server's config files and produce a prioritised, actionable report.

Procedure

  1. Locate the config tree. Look for, at the server root and per-world folders: server.properties, bukkit.yml, spigot.yml, paper-global.yml, paper-world-defaults.yml, */paper-world.yml, purpur.yml, velocity.toml, config/ plugin folders. Use Glob/Grep/Read. If only pasted text is available, audit that.
  2. Read each present file and check against the reference checklists:
    • references/paper-global-checklist.md — server-wide Paper settings + proxy forwarding.
    • references/common-footguns.md — the high-frequency mistakes that crash or lag servers.
  3. Cross-file consistency (the part single-file linters miss):
    • online-mode vs proxy forwarding: behind Velocity/Bungee the backend must run online-mode=false AND have modern forwarding configured, or skins/UUIDs break.
    • Never both spigot.yml: bungeecord: true and paper-global.yml: proxies.velocity.enabled: true — the server won't start.
    • view-distance in server.properties vs spigot.yml/paper-world.yml — the lower wins per-world; flag silent mismatches.
    • proxies.velocity.secret present and not the literal default/empty; forwarding.secret matches the proxy.
  4. Security pass:
    • RCON: if enable-rcon=true, confirm a strong rcon.password and that the port is firewalled / loopback-bound — never publicly exposed. (Critical if exposed.)
    • online-mode=false without a proxy in front = crackable server (high, unless intended).
  5. Performance pass: view-distance/simulation-distance sanity for the player count, entity-activation-range present, mob spawn limits set, entity-per-chunk-save-limit caps for experience_orb/arrow/ender_pearl, hopper tuning. Defer deep tuning to the performance-tuning skill but flag obvious wins here.
  6. YAML hygiene: detect literal tab characters (YAML forbids tabs — a common silent breakage), duplicate keys, and values that should be quoted.
  7. Plugin conflict pass: run check-conflicts.mjs to flag mutually exclusive plugins (two skyblock engines, two claim systems, ItemsAdder + Oraxen), missing deps (Vault without an economy, LibsDisguises without ProtocolLib), and proxy/Folia mismatches. Verify any hit with learn-plugin-docs before recommending a removal.

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.
