Horizon Platform SDK - Unity/C# Integration Guide

When to Use

Use this skill when a developer:

• Wants to integrate any Horizon Platform SDK feature in a Unity Meta Quest application
• Asks about setup, initialization, or dependencies for the Unity SDK package (com.meta.xr.sdk.platform)
• Needs help with a specific public platform API (achievements, IAP, users, etc.) in C#
• Is troubleshooting errors or status codes from any SDK package in Unity
• Asks about Core.AsyncInitialize, Oculus.Platform, or platform message handling

For Android/Kotlin apps, use the hz-platform-sdk skill instead.
