When your RealityKit entities aren't showing up, your gestures aren't firing, or your AR anchors are floating off into space, this is the diagnostic skill you reach for. It walks through systematic troubleshooting for the most common RealityKit pain points, from visibility issues to physics collisions to multiplayer sync problems. The time-cost annotations are a nice touch since AR debugging can eat up hours if you're checking things in the wrong order. Part of Charles Wiltgen's axiom collection, which also includes architecture patterns and API reference skills if you need to go deeper than just fixing what's broken.
