🎯 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.
# 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 |
