What problem does it solve? Setting up an AI-assisted game development toolchain on Windows is risky: tools may be macOS- or POSIX-bound, WSL boundaries break editor control, and silent installs can overwrite existing work. This Skill performs read-only discovery of a Windows environment and produces one confirmed, reversible setup proposal before anything changes. ## Core Features & Use Cases - Read-only environment discovery: Detects native Windows versus WSL, CPU architecture, PowerShell, package managers (winget, Chocolatey, Scoop), installed engines and DCC tools, GPU vendor, and MCP host selections without installing or launching anything. - Digest-confirmed proposals: Generates a plan with exact actions, immutable pins, licenses, permissions, backups, rollback operations, and a SHA-256 digest that the user must repeat verbatim before any apply step. - Compatibility enforcement: Rejects macOS bundles, POSIX executables, Apple-Silicon binaries, and Metal implementations as Windows routes, and treats WSL only as a disclosed fallback. - Use Case: A developer on Windows 11 with Unity and an NVIDIA GPU asks Codex to set up the game studio; the Skill inspects the machine, proposes a native PowerShell-based plan with rollback steps, and waits for digest confirmation before applying. ## Quick Start Ask Codex to inspect this Windows game project and propose one native, reversible Codex AI Game Studio edition setup, waiting for digest confirmation before changing anything.
