Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hz-unity-platform-sdk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
