## 🎯 What Is This?
A comprehensive suite of **34 production-grade Claude AI skills** for indie game developers — organized into **3 categories** covering the full game development lifecycle from concept to launch.
Each skill transforms Claude into a **domain-specific game dev expert** with real design frameworks, structured output templates, and production-grade workflows.
> [!TIP]
> **How it works:** Each skill is a structured `.md` prompt file. Drop it into a Claude Project or Claude Code, and Claude instantly becomes your game dev expert — with real industry frameworks, professional output templates, and deep domain knowledge.

## 🛠️ Setting Up Your Game Project
GameForge skills work out of the box for general questions. But to get engine-aware, project-specific guidance, copy a **starter config** into your game project.
```bash
# Copy the base config into your game project
cp starters/claude-config/CLAUDE.md /path/to/your-game/CLAUDE.md
mkdir -p /path/to/your-game/.claude
cp starters/claude-config/settings.json /path/to/your-game/.claude/settings.json
# Add your engine's config (pick one)
cat starters/godot/CLAUDE.md >> /path/to/your-game/CLAUDE.md # Godot
cat starters/unity/CLAUDE.md >> /path/to/your-game/CLAUDE.md # Unity
cat starters/unreal/CLAUDE.md >> /path/to/your-game/CLAUDE.md # Unreal
```
Fill in the `[BRACKETED PLACEHOLDERS]` with your game's details — project name, genre, one-liner description. Everything else works out of the box.

## 📦 Genre Packs
Genre packs are in-repo reference material that enrich existing skills with genre-specific design patterns, balance frameworks, and ideation prompts. They are not standalone skills — they are consumed by `game-brainstorm`, `game-designer`, `game-balance-check`, and `game-gdd-author` when a genre is specified.
| Pack | Lines | What It Covers |
|:---|:---:|:---|
| **Roguelike** | 888 | Permadeath, run structure, proc-gen, meta-progression, synergy systems, Monte Carlo validation, 6+ reference games |
| **Narrative** | 943 | Branching architecture, choice design, dialogue systems, consequence modeling, environmental storytelling, 10+ reference games |
