# setup-engine

Pins the game engine and its version in CLAUDE.md, and uses WebSearch to build reference docs when the version is newer than the model's training data.

## What it does

The skill picks a game engine and a version, then writes that choice into the project config. It never guesses a version: it looks one up through WebSearch or asks you. From there it updates the Technology Stack section of `CLAUDE.md`, fills in `project.yaml` and `technical-preferences.md`, prepares engine reference docs, and verifies the import.

Several modes are available. Full spec: `/setup-engine godot 4.7`. Engine only: `/setup-engine unity`, and the version gets looked up. With no arguments the skill walks you through a guided selection. Two subcommands handle maintenance: `refresh` updates the reference docs, `upgrade` migrates to a new engine version.

Config lives in two files. `project.yaml` is the primary store, `technical-preferences.md` is a legacy mirror, and `project.yaml` wins if they drift apart. Existing reference docs are never overwritten without asking. On Godot the skill calls `godot --version` and imports the project headless, so the engine has to be on your `PATH`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill setup-engine -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill setup-engine -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill setup-engine -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Donchitos/Claude-Code-Game-Studios setup-engine
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill setup-engine -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Donchitos/Claude-Code-Game-Studios --path .claude/skills/setup-engine
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Donchitos/Claude-Code-Game-Studios --skill setup-engine -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/Donchitos/Claude-Code-Game-Studios/tree/HEAD/.claude/skills/setup-engine/SKILL.md

## When to use it
- pin the engine and version in the project config
- look up the current engine version instead of guessing
- build API reference docs for a version past the model's training data
- migrate to a new engine version and refresh the docs
- add deprecated-API checks to specialist agents

## Example prompts
- Set up godot 4.7 for this project
- Pick the engine and version for me, I'm not sure which to use
- Refresh the engine reference docs: /setup-engine refresh

# Engine Setup

When this skill is invoked:

!`bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys workflow`

**Tier awareness.** The `workflow` tier resolved above governs which design
artifact this skill expects and the finish path it recommends in §12:
- **`minimal`** — the design artifact is the one-page `design/game-brief.md`
  (no GDDs, systems decomposition, or per-system design at this tier).
  `/setup-engine` runs *first* in the minimal path, so a missing brief here is
  normal, not a gap. The finish path is the 4-step floor.
- **`standard` / `full`** — the design artifact is `design/gdd/game-concept.md`
  and the finish path is the full pipeline.

If the block did not render (shell preprocessing disabled), assume `minimal` (the default).

## 1. Parse Arguments

Four modes:

- **Full spec**: `/setup-engine godot 4.7` — engine and version provided
- **Engine only**: `/setup-engine unity` — engine provided, version will be looked up
- **No args**: `/setup-engine` — fully guided mode (engine recommendation + version)
- **Refresh**: `/setup-engine refresh` — update reference docs (see Section 10)
- **Upgrade**: `/setup-engine upgrade [old-version] [new-version]` — migrate to a new engine version (see Section 11)

---

## 2. Guided Mode (No Arguments)

**Read `references/2-guided-mode.md` now and follow it** — this phase's steps are in that file, not here. Read it again if the conversation was compacted or resumed during this phase.

## 3. Look Up Current Version

**Read `references/3-version.md` now and follow it** — this phase's steps are in that file, not here. Read it again if the conversation was compacted or resumed during this phase.

## 4. Update CLAUDE.md Technology Stack

**Read `references/4-claude-md-stack.md` now and follow it** — this phase's steps are in that file, not here. Read it again if the conversation was compacted or resumed during this phase.

## 5. Populate Technical Preferences
