## About

# 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.

## Quick Start

- **Setup guide**: https://developers.meta.com/horizon/documentation/unity/ps-platform-intro/
- **UPM Package**: `com.meta.xr.sdk.platform` via Unity Package Manager
- **Namespace**: `Oculus.Platform` (backward compatible with legacy LibOVRPlatform SDK)

## Available APIs

| Application | `application` | Get app version, launch other apps, manage self-update downloads |

| Asset File | `asset-file` | List, download, cancel, and delete downloadable asset files (DLC) |
| Challenges | `challenges` | Time-bound score competitions on top of leaderboards |

| Users | `users` | Retrieve user profiles, friends, access tokens, identity verification |

## How to Use

1. **First**, read `references/common-setup.md` for shared setup instructions, initialization code, Editor testing, and common patterns that apply to all APIs.
2. **Then**, read the specific reference file for the API you need (e.g., `references/iap.md` for in-app purchases).

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.
