## TL;DR

Cloud XR development combines real-time rendering, XR input, streaming transport, and spatial interaction. It should be treated as a latency-sensitive systems problem, not just a graphics feature.

## Core Explanation

Cloud XR moves some rendering or application work away from the headset or client device. That can make heavier scenes possible on lighter clients, but it also introduces streaming, network, synchronization, and comfort constraints. OpenXR provides a cross-platform XR API anchor, WebRTC is a common real-time media/data primitive, and vendor platforms such as CloudXR define concrete server-client streaming models.

For AI-assisted production, the useful boundary is to ask agents to work on one layer at a time: interaction logic, build settings, streaming integration, telemetry, or comfort review. Combining all layers in one prompt makes failure modes hard to review.

## AI Agent Use

Use this entry when asking an AI coding agent to inspect a cloud-rendered XR prototype, XR interaction layer, or streaming proof of concept. The prompt should name the target device, transport, engine, test network, and comfort constraints.
