Audit Config

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.

Reporting format

Group findings by severity and give each a one-line fix:

CRITICAL — will crash or lose data
  - [file:key] problem → fix
HIGH — lag or security
  - …
MEDIUM — quality / maintainability
LOW — style / nitpick

End with a short "Looks good" list of things that are already correct, so the user trusts the audit. If a referenced plugin's keys are unfamiliar, call the learn-plugin-docs skill before judging them — do not invent keys.

Helper scripts

• Seed the audit by scanning the tree:

  node "${CLAUDE_PLUGIN_ROOT}/skills/audit-config/scripts/scan-server-tree.mjs" <server-root>
  #   detects software, config files, worlds, plugins, key settings, and tab-character warnings
  #   add --json for machine-readable output
  

• Find paper-world.yml overrides (you should only override keys you mean to):

  node "${CLAUDE_PLUGIN_ROOT}/skills/audit-config/scripts/diff-against-defaults.mjs" \
       <world>/paper-world.yml paper-world-defaults.yml
  

• Check plugin conflicts / missing deps (uses references/conflict-rules.json + the profile):

  node "${CLAUDE_PLUGIN_ROOT}/skills/audit-config/scripts/check-conflicts.mjs" <server-root>
  #   or --list "LuckPerms,EssentialsX,Vault"   or --profile   (add --json for machine output)
  

• Write the server profile so later answers stop re-asking version/host/stack:

  node "${CLAUDE_PLUGIN_ROOT}/skills/audit-config/scripts/scan-server-tree.mjs" <server-root> --write-profile
  

All are read-only on the scanned tree (only --write-profile writes, into mcwrench's _cache/) and run on stock Node ≥18. Use them to orient, then read the flagged files.
