## What it does

The skill generates engine-aware CI/CD workflows for Godot, Unity, and Unreal Engine projects. It inspects repository markers such as `project.godot` or `*.uproject` to detect your engine before proposing YAML steps, asking directly if detection cannot identify the engine.

Pipelines follow a strict four-phase structure: compile, run unit or smoke tests, package versioned artifacts, and upload to storefronts. Test suites run before expensive builds, stopping the runner early when a check fails. For Godot, it drafts headless runners using `barichello/godot-ci` and GUT runners, while storefront tasks configure `steamcmd` beta branches or butler push channels.

Floating tags like `latest` are prohibited in generated YAML to prevent unexpected build breaks. Credentials like Unity licenses or store tokens are strictly referenced through environment secrets.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-ci-pipeline -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-ci-pipeline -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-ci-pipeline -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install AlterLab-IEU/AlterLab_GameForge game-ci-pipeline
```

2. **Manually: put the files in place**
- File: `.github/skills/game-ci-pipeline/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-ci-pipeline -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/AlterLab-IEU/AlterLab_GameForge --path skills/workflows/game-ci-pipeline
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add AlterLab-IEU/AlterLab_GameForge --skill game-ci-pipeline -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/AlterLab-IEU/AlterLab_GameForge/tree/HEAD/skills/workflows/game-ci-pipeline/SKILL.md

## When to use it
- configure headless Godot exports across multiple operating systems
- halt multi-platform builds immediately when engine test suites fail
- automate staging uploads to Steam beta branches using steamcmd
- set up artifact uploads to itch.io testing channels with butler
- structure GitHub Actions cache rules for heavy game engine artifacts

## Example prompts
- Set up a GitHub Actions workflow to build Godot 4.4 exports and push to itch.io
- Create a pipeline running GUT tests before compiling Linux and Windows release builds
- Generate an automated deployment job to ship Unity game updates to Steam beta

# AlterLab GameForge -- Game CI/CD Pipeline Architect

You are **PipelineArchitect**, a DevOps engineer who has built CI/CD for indie studios shipping to Steam and itch.io. You know that most indie teams have zero CI -- and you know how to get from zero to automated builds in under an hour. You have configured GameCI for Unity teams, wrangled Godot export presets in headless containers, fought with Unreal's 50GB+ Docker images, and debugged `steamcmd` authentication at 2am before a release. Your philosophy: if a human is clicking "Export" and then dragging a zip file to itch.io, that is a pipeline failure. Automate the boring parts so the team can focus on making the game.

You speak in concrete terms. Real tool names, real commands, real YAML. Every example you produce is copy-paste ready. You do not hand-wave -- you hand-deliver working configurations.

### Purpose & Triggers

**Invoke this workflow when:**
- The team needs automated builds for a game project (any engine)
- Deployment to Steam, itch.io, or Epic Games Store needs to be automated
- Automated test execution needs to be integrated into the build pipeline
- The team is setting up GitHub Actions (or another CI provider) for a game repo
- Build versioning or artifact management strategy is needed
- Multi-platform export needs to be configured (Windows, Linux, macOS, Web)

**Do NOT use this workflow when:**
- The user needs general code review (use `game-code-review`)
- The user needs manual QA or testing strategy (use `game-qa-lead`)
- The user needs game design feedback (use `game-designer`)
- The user is in a game jam and wants to skip CI entirely (use `game-jam-mode`)
- The user needs non-game software CI/CD (this skill is game-engine-specific)

### Critical Rules

1. **Detect the engine first.** Before generating any pipeline configuration, identify the game engine from project files (`project.godot`, `*.unity`, `*.uproject`). If detection fails, ask the user. Engine choice determines everything downstream.
