## What it does

The skill inspects a game project and returns a scored report across four areas. It starts by detecting the engine (Three.js, Phaser or another), reading `package.json`, the entry point and `index.html,` then works through the checklists.

Architecture: is there an EventBus, a single GameState, centralized constants, an orchestrator, core/systems/gameplay/ui/level layers. Performance: is `getDelta()` capped, are temp objects pooled, are Three.js geometries and materials disposed, are listeners cleaned up on scene transitions. Then code quality and monetization readiness — a points system, session tracking, a structure that could support server-side score validation.

You get scores per section, a prioritized list of recommendations in plain language, and a section on what already works. Nothing in the codebase is changed: this is analysis, and `improve-game` handles the fixes. Pass the project path as an argument, or it falls back to the current directory.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill review-game -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill review-game -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill review-game -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PlayableIntelligence/game-creator review-game
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill review-game -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PlayableIntelligence/game-creator --path skills/review-game
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PlayableIntelligence/game-creator --skill review-game -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/PlayableIntelligence/game-creator/tree/HEAD/skills/review-game/SKILL.md

## When to use it
- understand an unfamiliar game project before extending it
- spot memory leaks from undisposed Three.js resources
- check whether event listeners pile up across scene transitions
- assess if the scoring system can support server-side validation
- get a prioritized fix list instead of generic advice

## Example prompts
- /review-game examples/flappy-bird
- review my game architecture in the current folder
- audit my game code and tell me what to fix first

## Performance Notes

- Take your time to do this thoroughly
- Quality is more important than speed
- Do not skip validation steps

# Review Game

Analyze an existing game codebase and provide a structured review. This is the final step in the pipeline — it checks everything is wired up correctly and gives you a quality score.

## Instructions

Analyze the game at `$ARGUMENTS` (or the current directory if no path given).

### Step 1: Identify the game

- Detect the engine (Three.js, Phaser, or other)
- Read `package.json` for dependencies and scripts
- Read the main entry point and index.html
- Identify the game concept/genre

### Step 2: Architecture Review

Check for these required patterns and report compliance:

- [ ] **EventBus**: Is there a centralized event system? Are modules decoupled?
- [ ] **GameState**: Is there a centralized state singleton?
- [ ] **Constants**: Are config values centralized or scattered as magic numbers?
- [ ] **Orchestrator**: Is there a main Game class that initializes everything?
- [ ] **Directory Structure**: Is code organized into core/systems/gameplay/ui/level layers?
- [ ] **Event Constants**: Are events defined as named constants or raw strings?

### Step 3: Performance Review

Check for common issues:

- [ ] **Delta time capping**: Is `getDelta()` capped to prevent death spirals?
- [ ] **Object pooling**: Are temp objects reused in hot loops?
- [ ] **Resource disposal**: Are Three.js geometries/materials/textures disposed?
- [ ] **Event cleanup**: Are event listeners cleaned up on scene transitions?
- [ ] **Asset loading**: Are assets preloaded with progress feedback?

### Step 4: Code Quality

- [ ] **No circular dependencies**: Modules flow one direction
- [ ] **Single responsibility**: Each module has one clear job
- [ ] **Error handling**: Event handlers wrapped in try/catch
- [ ] **Consistent naming**: Events use `domain:action`, files use PascalCase

### Step 5: Monetization Readiness

- [ ] **Points system**: Is there a scoring/points mechanism?
- [ ] **Session tracking**: Can game sessions be identified?
- [ ] **Anti-cheat potential**: Is score validation server-side or at least structured for it?
- [ ] **Play.fun integration**: Any existing SDK integration?
```
