Game Porting Toolkit 4 introduces agentic skills and a porting assistant that give AI coding agents (like Claude Code) the platform expertise needed to autonomously port games from D3D12/Windows to Metal/macOS, including new macOS 27 command-line tools gpucapture and gpudebug for fully autonomous GPU frame analysis.
ā¢ Dramatically reduces game porting time by embedding Metal best practices, synchronization patterns, and anti-pattern detection directly into the agent's workflow ā no manual expertise hand-holding required.
ā¢ New gpucapture and gpudebug CLI tools on macOS 27 enable coding agents to capture and analyze GPU frames autonomously, closing the last major gap in agentic porting workflows.
ā¢ The structured discover ā plan ā execute ā validate loop with milestone-scoped expert skills means fewer regressions and systematic quality gates throughout the port.
