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 | $0.00097 | $0.03057 |
| Opus 5.5 | $0.00039 | $0.01223 |
| Sonnet 5.5 | $0.00019 | $0.00611 |
| Haiku 4.5 | $0.00010 | $0.00306 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 VR devices. 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
Running SDK code — drive a live Editor with unity-cli
Everything here is Editor-only C#. Run it against an open Editor instead of hand-editing scene, manifest, or settings files. Connecting, --project-path, and Safe Mode recovery are in the unity-cli skill.
unity status --format json # look for state "ready"
unity command run_script --project-path <proj> --file AgentScripts/Setup.cs --entry Setup.Run --format json
Prefer run_script over eval — put the .cs outside Assets/ (path resolves against the project root) so writing it triggers no import or domain reload, and shell quoting can't mangle C# literals.
SDK-specific gotchas:
- No type-discovery reflection needed.
run_scriptreferences every loaded assembly, soOVRProjectSetup,OVRManifestPreprocessoretc. compile directly;using System.Reflection;andBindingFlagswork for the internal bits (_principalRegistry,GetTasks). - Pass
silentMode: trueto anything that may open anEditorUtility.DisplayDialog— a modal blocks the request until it times out. - Async work lands after the script returns (
FixAllAsync,Client.Add) — verify in a separate follow-uprun_script; neverTask.Wait()on the main thread. - Scene edits:
MarkSceneDirty+SaveScene(+AssetDatabase.SaveAssets()), then read the value back. - Driving Unity MCP instead of the CLI? Its constraints break the above: references/unity-mcp-fallback.md.
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)

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 (237 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 97 tokens to every session and 3,057 once invoked, about $0.0004 per session on Opus 5.5. 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.
