What it does

Compare Version Modules is an agent skill from opanel-mc/opanel. Compare two server-platform adaptation modules of the same platform but different Minecraft/game versions (e.g. forge-1.21.5 vs forge-1.21.8), surfacing only the real API / 写法 differences by normalizing away package-name and version-string noise. Use when the user asks to 对比/比较/diff two version modules, find what changed between two <platform-<version directories (forge/neoforge/fabric/spigot/folia), or understand how to port an adaptation from one game version to the next.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/compare.sh`).

The repository describes itself as: A Minecraft server management panel for Paper / Folia / Leaves / Fabric / Forge / NeoForge / Pumpkin servers. The licence is GPL-3.0.

Workflow steps

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

Run scripts/compare.sh / / from the repo root.
Read the diff. Each ===== ===== block is one changed file.
Group the findings for the user, e.g.
Note knock-on changes: a constructor signature change in one file usually

Read from SKILL.md and the folder at commit 3a61e1a. 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
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:

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

Compare Version Modules loads about 823 tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 341 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~127
When it runs · the whole SKILL.md, loaded when a task matches: ~823

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); the scripts in this folder are not scanned.

description: Compare two server-platform adaptation modules of the same platform but different Minecraft/game versions (e.g. forge-1.21.5 vs forge-1.21.8), surfacing only the real API / 写法 differences by normalizing away package-name and version-string noise.

Compare version modules

Adaptation modules for different game versions of the same platform do the same job with slightly different code. This skill isolates the meaningful deltas (API renames, signature changes, new imports, build-config bumps) from the mechanical noise (package names and version numbers that differ in every file).

Quick start

Run the bundled script with the two module directory paths. Modules now live under their platform folder (fabric/, forge/, neoforge/, bukkit/), so pass the platform-prefixed path:

bash

bash <skill-dir>/scripts/compare.sh forge/forge-1.21.5 forge/forge-1.21.8

(The script derives the package token from the directory's basename, so the platform-folder prefix does not affect normalization.)

It pairs files across the two modules, normalizes each module's package token, directory name, and version string into shared placeholders, then prints a per-file diff plus a summary line. Files that are identical after normalization are omitted; files present in only one module are flagged ONLY IN ....

Convention it relies on

Directory <platform>/<platform>-<version> ↔ java package net.opanel.<platform>_<ver>, where the package token is the module directory's basename with - and . turned into _:

forge-1.21.5 → forge_1_21_5
spigot-1.16.1 → spigot_1_16_1
neoforge-1.21.3 → neoforge_1_21_3

This holds for forge / neoforge / fabric / spigot / folia in this repo.

Workflow

Run scripts/compare.sh <platform>/<older> <platform>/<newer> from the repo root.
Read the diff. Each ===== <path> ===== block is one changed file.
Group the findings for the user, e.g.:
- Build config — gradle.properties (version range, loader version), build.gradle (new repos/deps), pack.mcmeta (pack_format).
- API changes — renamed/moved imports, changed method signatures, replaced types (e.g. GameProfile → NameAndId).
- New behavior — added listeners, fields, null guards, newly-implemented interfaces.
Note knock-on changes: a constructor signature change in one file usually forces edits at every call site — call those out together.
Skip files reported only as version-string/package differences; the script already removed those, so anything left is a genuine difference worth reporting.

Notes

The right bound of minecraft_version_range (the next version) is a real difference, not noise, so it is intentionally shown.
If a module pair lives outside the repo root, pass full/relative paths: compare.sh path/to/forge-1.21.8 path/to/forge-1.21.9 (any path works; only the basename matters).
The script reads files only; it never edits. Safe to run anytime.
