Axiom Games

A comprehensive reference for building 2D and 3D games on Apple platforms, covering SpriteKit, SceneKit, and RealityKit. The real value is in the diagnostics: it has a 5-step physics bitmask checklist that catches phantom collision bugs in 2 minutes instead of 2 hours, and an automated auditor that scans for anti-patterns like SKShapeNode overuse, action memory leaks, and tunneling issues. Routes SceneKit questions to axiom-graphics since it's soft-deprecated as of iOS 26. The anti-rationalization table is honest about common mistakes, like the default 0xFFFFFFFF physics bitmask that causes collisions with everything. If you're building any kind of game or interactive simulation in Swift, this catches the gotchas before you waste time on them.

Games

You MUST use this skill for ANY game development, SpriteKit, SceneKit, RealityKit, touch controls, game controller, or interactive simulation work.

Auditors are skills here. Where this router says "Launch some-auditor agent", invoke the matching Codex skill instead — same procedure, no Claude Code agent required.

Available: axiom-audit-spritekit.

The ones that shell out — builds, tests, simulators, crash symbolication — need shell access to run.
