When to Use
Use this skill when a developer:
- Wants to integrate any Horizon Platform SDK feature in a Unity Meta VR 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.

How to Use
- First, read
references/common-setup.mdfor shared setup instructions, initialization code, Editor testing, and common patterns that apply to all APIs. - Then, read the specific reference file for the API you need (e.g.,
references/iap.mdfor in-app purchases). - For exact signatures, query the API index instead of guessing:
metavr docs api-search "<feature> <operation>", thenmetavr docs api-details <entry>for the full entry.
Each reference file contains only the package-specific content: API operations, data types, examples, and package-specific notes. The common setup, initialization patterns, and coding conventions are centralized in common-setup.md to avoid duplication.
