Meta XR Core SDK (com.meta.xr.sdk.core)

The Meta XR Core SDK is the foundational Unity package for developing VR and MR applications targeting Meta VR devices. It provides the core XR rig, device management, input handling, and access to platform features like passthrough, hand tracking, spatial anchors, and scene understanding.

Running SDK code — drive a live Editor with unity-cli

Everything here is Editor-only C#. Run it against an open Editor instead of hand-editing scene, manifest, or settings files. Connecting, --project-path, and Safe Mode recovery are in the unity-cli skill.

unity status --format json          # look for state "ready"
unity command run_script --project-path <proj> --file AgentScripts/Setup.cs --entry Setup.Run --format json

Prefer run_script over eval — put the .cs outside Assets/ (path resolves against the project root) so writing it triggers no import or domain reload, and shell quoting can't mangle C# literals.
