ar-vr-xr from travisjneuman/.claude is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add travisjneuman/.claude/ar-vr-xr@git:20260328.75c803aPins git:20260328.75c803a in mdr.lock. Pin the fingerprint instead.

AR/VR/XR development with Unity XR, WebXR, ARKit, ARCore, Meta Quest SDK, and spatial computing. Use when building augmented reality, virtual reality, mixed reality applications, or spatial experiences.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# AR/VR/XR Development
## Platform Overview
| Platform | SDK | Target Devices |
|----------|-----|----------------|
| **Unity XR** | XR Interaction Toolkit | Quest, Vision Pro, PCVR, mobile |
| **WebXR** | Three.js, A-Frame, Babylon.js | Any WebXR browser |
| **ARKit** | RealityKit, ARKit | iPhone, iPad, Vision Pro |
| **ARCore** | Sceneform, ARCore | Android devices |

## Unity XR
```csharp
// XR Interaction Toolkit setup
using UnityEngine.XR.Interaction.Toolkit;
public class GrabbableObject : XRGrabInteractable
{
protected override void OnSelectEntered(SelectEnterEventArgs args)
{
base.OnSelectEntered(args);
// Object grabbed
}
protected override void OnSelectExited(SelectExitEventArgs args)
{
base.OnSelectExited(args);
// Object released
}
}
```
### Unity XR Best Practices
- Target 72-120 FPS (platform-dependent) — frame drops cause nausea
- Use single-pass instanced rendering for stereo
- Bake lighting where possible, limit dynamic lights to 1-2
- Draw calls: <100 for mobile VR, <500 for PCVR

How to install
mdr add travisjneuman/.claude/ar-vr-xr@sha256:e5074b7b8c023f8aThe line at the top of this page pins the label git:20260328.75c803a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
