GitHub - Totes-MickGOATs/mcgoats-game-template: AI-powered game development template with CI/CD, auto-merge queue, TDD enforcement, 3-layer master protection, and 50+ skills for Godot/Unity/Unreal

AI-powered game development template with battle-tested CI/CD, auto-merge queues, TDD enforcement, and Claude Code integration. Start new game projects with production-grade infrastructure from day one.

First Time? Start Here

This template is designed to work with Claude Code (Anthropic's AI coding assistant). It will walk you through the entire setup — engine selection, GitHub configuration, CI pipeline, and your first feature branch.

Option A: Interactive AI Setup (Recommended)

Open a terminal in this project directory and run:

Then type:

Claude will guide you through everything step-by-step: checking prerequisites, choosing your engine (Godot/Unity/Unreal), configuring GitHub branch protection, and verifying your CI pipeline works.

Option B: Manual Setup

If you prefer to set things up yourself, follow the checklist in SETUP.md.

Already Set Up?

Once your project is configured, here are the key commands to know:

All development happens on feature branches — Claude handles the branching, commits, PRs, and CI for you.

What You Get

• 3-layer main branch protection — Claude Code PreToolUse hook + git pre-commit hook + GitHub branch protection
• Auto-merge queue — FIFO squash-merge triggered by ready-to-merge label
• CI pipeline — Common lint + engine-specific checks as reusable workflows
• Post-merge safety net — Full test suite runs after merge, auto-creates issues on failure
• Claude Code integration — Hooks, commands, statusline, subagent quality gates
• TDD enforcement — Red-Green-Commit workflow baked into project conventions
• Worktree-based branching — Isolated feature branches with import cache seeding
• System manifests — Track which files belong to which game system
• CLAUDE.md hierarchy — Per-directory documentation that AI agents read automatically
• Skills library — 5 engine-agnostic skills + engine-specific skills loaded on demand
• Python tooling — uv-managed scripts for validation, coverage, and docs freshness

Engine Support

Godot support is battle-tested across a shipping game project. Unity and Unreal modules are starting points — contributions welcome.

Quick Start

1. Create your project

Click "Use this template" on GitHub, or:

gh repo create my-org/my-game --template Totes-MickGOATs/mcgoats-game-template --public
git clone https://github.com/my-org/my-game.git
cd my-game

2. Choose your engine

./tools/setup-engine.sh godot   # or: unity, unreal

This copies engine-specific configs, CI workflows, hooks, skills, and lint configs into the right places, then removes the engine/ directory.

3. Configure GitHub

1. Branch protection on main:
   • Require PR before merging
   • Require status checks: Lint & Preflight (add engine-specific checks too)
   • No force push, no deletion
2. Repository secret MERGE_TOKEN: a PAT with repo + workflow scopes (for auto-merge)
3. Enable auto-merge in repo settings

4. Start building

just worktree-create my-feature   # Create feature branch + worktree
# ... develop with TDD ...
just ship                         # Push + create PR + watch CI
