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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00090 | $0.02685 |
| Opus 5 | $0.00045 | $0.01342 |
| Sonnet 5 | $0.00018 | $0.00537 |
| Haiku 4.5 | $0.00009 | $0.00268 |
Grade A, and why
hz-unity-meta-core-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 9d 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.

Meta XR Core SDK (com.meta.xr.sdk.core)
The Meta XR Core SDK is the foundational Unity package for developing VR and MR applications targeting Meta Quest headsets. It provides the core XR rig, device management, input handling, and access to platform features like passthrough, hand tracking, spatial anchors, and scene understanding.
Package: com.meta.xr.sdk.core
Finding the SDK Source
The package com.meta.xr.sdk.core may be located in different places depending on the project setup:
Library/PackageCache/com.meta.xr.sdk.core@<hash>/(cached from registry)Packages/com.meta.xr.sdk.core/(local package reference)- A custom on-disk path (embedded or local folder)
Before searching for SDK source, first locate the package root by searching for a known file by filename pattern:
**/com.meta.xr.sdk.core*/Scripts/OVRManager.cs
Then use the resolved parent path for all subsequent search operations.
CRITICAL: After Any OVRProjectConfig or OVRManager Feature Change
Any time you modify OVRProjectConfig or OVRManager feature settings (hand tracking, passthrough, boundaryless, target devices, etc.), you MUST call GenerateOrUpdateAndroidManifest() and verify the result. See references/android-manifest.md for the full workflow.
Quick Reference
| Component | Purpose |
|---|---|
| OVRCameraRig | Primary XR rig prefab replacing Unity's Main Camera |
| OVRManager | Singleton managing device state, features, and configuration |
| OVRInput | Unified API for controller input and tracking |
| OVROverlay | Compositor layers for sharper text, UI, and video |
| OVRPassthroughLayer | Enables passthrough visualization |
| OVRSpatialAnchor | World-locked spatial anchors |
| OVRBoundary | Guardian boundary system access |
| OVRProjectSetup | Project Setup Tool for configuration tasks |
OVRCameraRig: The Primary XR Rig
The OVRCameraRig prefab is the primary GameObject to add to create a VR/MR scene. It replaces Unity's conventional Main Camera and provides:

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-meta-core-sdk is a skill published in the GitHub repository meta-quest/agentic-tools (192 stars, last pushed 18d ago), licensed Apache-2.0. It adds 90 tokens to every session and 2,685 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
