Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00096 | $0.00835 |
| Opus 5 | $0.00048 | $0.00417 |
| Sonnet 5 | $0.00019 | $0.00167 |
| Haiku 4.5 | $0.00010 | $0.00084 |
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.
Quick Start
- Setup guide: https://developers.meta.com/horizon/documentation/unity/ps-platform-intro/
- UPM Package:
com.meta.xr.sdk.platformvia Unity Package Manager - Namespace:

What this file has done since we first saw it
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.

hz-unity-platform-sdk is a skill published in the GitHub repository meta-quest/agentic-tools (189 stars, last pushed 14d ago), licensed Apache-2.0. It adds 96 tokens to every session and 835 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings.
