Horizon API Upgrade Skill

For Unity projects using the Meta XR SDK, use the dedicated hz-unity-sdk-upgrade skill. Continue here for Unreal, native Android or Spatial SDK, Web or IWSDK, and general cross-platform upgrade planning.

When to Use

Use this skill when:

• Upgrading an existing Meta VR application to a newer Horizon OS SDK version
• Fixing deprecated API warnings or compilation errors after an SDK update
• Migrating between major API versions (e.g., VrApi to OpenXR)
• Understanding what changed between SDK releases
• Planning an upgrade path for a project that has fallen behind on SDK versions
