## What it does

The skill runs a pre-release check with `um publish check ./MyMod --game "<game install folder>"`. It flags game-file copies, leaked keys, `.env` files, decompiler traces, absolute paths, large engine archives, and missing README or fal credits. A `FAIL` should block the release until the package is fixed.

It then maps the package to the target ecosystem: tModLoader, BepInEx and Thunderstore, Nexus Mods, Steam Workshop, Minecraft, AoE2 DE, ROM hacks, or GameMaker. For Nexus Mods with install choices, it points to a FOMOD installer. The skill also covers requirements, install and uninstall notes, logs, compatibility, conflicts, licences, and AI disclosure.

Release preparation includes semver, the supported game version, and a changelog. After a game update, it calls for rerunning the in-game test scene before changing the version. It can draft a video-led post with agent and fal credits, while the final publishing action stays with you.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rehan-remade/universal-modder --skill publish-mod -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/publish-mod/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/publish-mod/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rehan-remade/universal-modder --skill publish-mod -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/publish-mod/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rehan-remade/universal-modder --skill publish-mod -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/publish-mod/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rehan-remade/universal-modder publish-mod
```

2. **Manually: put the files in place**
- File: `.github/skills/publish-mod/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rehan-remade/universal-modder --skill publish-mod -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rehan-remade/universal-modder --path skills/publish-mod
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/publish-mod/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rehan-remade/universal-modder --skill publish-mod -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rehan-remade/universal-modder/tree/HEAD/skills/publish-mod/SKILL.md

## When to use it
- check a mod for copied game files and leaked keys
- build an archive for a target mod platform
- write README installation and requirement steps
- add credits and AI disclosure
- draft a changelog and release post

## Example prompts
- Check my mod before release and resolve every `FAIL`.
- Package this mod for Nexus Mods and write the installation README.
- Draft a mod release post that credits the video and contributors.

name: publish-mod
description: Package and release a finished game mod. Covers the pre-release lint (no game files, decompiled code or leaked keys), README and install steps, credits and AI disclosure, versioning, where to upload (Nexus Mods, Steam Workshop, Thunderstore, mod.io, GitHub releases), and the post with a video. Use when the user wants to ship, share, upload, release or post a mod.

# Publish a mod

## 1. Lint
```bash
um publish check ./MyMod --game "<game install folder>"
```
- **FAIL:** files byte-identical to game files, leaked keys (fal/Anthropic/OpenAI/GitHub/AWS), `.env` files.
- **WARN:** decompiler fingerprints in source (`FUN_`/`DAT_`/`sub_` names, "Decompiled with" headers), large
  engine archives, absolute user paths, a missing README, fal assets without credit.

Fix every FAIL. Resolve each WARN deliberately. For example, AoE2 data mods do ship a modified `.dat`, which
is the platform's norm.

## 2. Package the way the platform expects

| Platform / loader | Package |
|---|---|
| tModLoader | Build → `.tmod`; publish from the in-game Mod Sources menu (Steam Workshop) |
| BepInEx / Thunderstore | zip with `manifest.json`, `icon.png` (256×256), `README.md`, `plugins/<Mod>.dll`; dependency strings like `BepInEx-BepInExPack-5.4.2100` |
| Nexus Mods | zip laid out as it installs (`Data/...` for Bethesda, `BepInEx/plugins/...`, `ue4ss/Mods/...`, `~mods/*.pak`) |
| AoE2 DE | the official mod site (ageofempires.com/mods) or the in-game uploader; data mods include `resources/_common/dat/...` |
| Steam Workshop | the game's own uploader or SDK tool |
| Minecraft | Modrinth / CurseForge jar with `fabric.mod.json` / `neoforge.mods.toml` |
| ROM hacks / GameMaker | patches only (BPS/IPS/xdelta), never the modified game file |

A Nexus mod with options gets a FOMOD installer: see the
[FOMOD tutorial](https://fomod-docs.readthedocs.io/en/latest/tutorial.html) and
[STEP's FOMOD guide](https://stepmodifications.org/wiki/Guide:FOMOD). Nexus Mods' own
[modding wiki](https://modding.wiki/en/home) covers the rest of their site's conventions.

## 3. README (in the zip and on the page)
- What it adds: bullets, a GIF or the showcase video.
- Requirements: game version, the loader and its version, dependencies.
- Install, uninstall and troubleshooting (where the log is).
- Compatibility: multiplayer? Known conflicts?
- Credits:
  - the loader and libraries;
  - references you learned from;
  - **"Art/audio generated with fal (fal.ai) using <models>"** (`fal_manifest.jsonl` lists them);
  - honest AI disclosure (which agent and model built it).
- License for your code (MIT/Apache is common). Your assets' terms follow the models' licenses.
