What it does

Module Config Change is an agent skill from kernitus/BukkitOldCombatMechanics. Use for config.yml, module enablement, modesets, config migration, configurable module assignment, and per-module option changes; do not use for unrelated integration-test triage, release publishing, or PR summaries.

Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Integration testing. The repository describes itself as: Minecraft plugin to configure combat mechanics for 1.9 onwards. The licence is MPL-2.0.

When your agent uses it

  • Module enablement
  • Config migration
  • Configurable module assignment
  • Per-module option changes

Example prompts

  • “/module-config-change”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Identify whether the change is a default, migration, reload, or runtime behaviour change.
  2. Update bundled config comments and defaults together when needed.
  3. Preserve existing user config where migration should be non-destructive.
  4. Run scripts/validate-module-assignments.sh for a quick static check that bundled configurable lists do not conflict across…
  5. Add or update integration coverage where practical.
  6. If adding an integration spec, register it in KotestRunner.withClasses(...).
  7. Validate both enabled and disabled/modeset-scoped behaviour for options that change item state or player state.

What it can do on your machine

Read from SKILL.md and the folder at commit e66e7a9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Module Config Change loads about 914 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 392 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~914

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Module Config Change

Use this skill when changing module configuration, defaults, migration, or runtime handling driven by config.yml.

When to use

  • Editing bundled config.yml defaults or comments.
  • Adding or changing module settings such as attack cooldown, attack range, sword blocking, old tool damage, tooltip, potion effects, or durability behaviour.
  • Changing always_enabled_modules, disabled_modules, modesets, or config migration logic.
  • Validating reload behaviour after config changes.
  • Writing tests around config assignment, migration, or modeset-specific behaviour.

When not to use

  • Do not use for ordinary test execution unless the test is config-specific; use integration-test-verification.
  • Do not use for Java/NMS compatibility strategy unless the config option depends on runtime feature detection; use compatibility-strategy as well.
  • Do not use for release workflow edits; use release-readiness-review.

Mandatory configuration rules

  • Configurable modules must appear in only one top-level assignment category: always_enabled_modules, disabled_modules, or the aggregate modesets category. The same module may appear in more than one individual modeset because modesets are alternative player modes.
  • Duplicate entries are still invalid within the same exact list or individual modeset.
  • Internal modules (modeset-listener, attack-cooldown-tracker, entity-damage-listener) are always enabled and must not be listed.
  • Reload/enable should fail for invalid module assignment.
  • Do not add per-module enabled: toggles; the module lists and modesets are authoritative.
  • Keep bundled comments clear for server owners and use British English.

Change checklist

  1. Identify whether the change is a default, migration, reload, or runtime behaviour change.
  2. Update bundled config comments and defaults together when needed.
  3. Preserve existing user config where migration should be non-destructive.
  4. Run scripts/validate-module-assignments.sh for a quick static check that bundled configurable lists do not conflict across always_enabled_modules, disabled_modules, and the aggregate modesets category; do not duplicate entries within the same exact list or modeset; and do not include internal modules.
  5. Add or update integration coverage where practical.
  6. If adding an integration spec, register it in KotestRunner.withClasses(...).
  7. Validate both enabled and disabled/modeset-scoped behaviour for options that change item state or player state.

Useful known behaviours

  • old-tool-damage.tooltip.enabled is enabled by default so players can see configured damage in-game.
  • attack-range is listed in disabled_modules by default and is Paper 1.21.11+ only.
  • sword-blocking.paper-animation defaults to true; when false, sword blocking uses the legacy shield fallback and strips stale Paper consumable state.
  • Attack cooldown supports disable-attack-cooldown.held-item-attack-speeds.<MATERIAL> with XMaterial/Material matching and restores vanilla attack speed when disabled.
