Unity-TheWorldBeyond AGENTS.md

A set of repository instructions for a Unity mixed-reality sample made for Meta Quest headsets. It covers features such as passthrough, hand or controller interaction, voice input, and spatial audio.

In plain words
What is it for?
Use it when building, running, or modifying The World Beyond sample and its Quest or Unity integrations.
Why use it?
It explains project-specific setup and device limitations that are easy to miss, such as needing a captured room and using an APK on macOS.

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

Unity-TheWorldBeyond AGENTS.md 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 2d 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 — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Instructions — The World Beyond

Unity mixed-reality showcase that demonstrates Scene API, Passthrough, Interaction SDK, Voice SDK, and Audio Spatializer features as a reference / template for MR projects on Meta Quest.

Source-of-truth files (read these first, do not duplicate their contents in this file)

For setup, build steps, SDK versions, and project layout, read:

  • README.md — official setup and instructions
  • ProjectSettings/ProjectVersion.txt — Unity editor version
  • Packages/manifest.json — Unity package versions (MRUK, Meta XR Interaction SDK, Voice SDK, Audio Spatializer)
  • Documentation/ — per-feature deep dives (Scene API, Passthrough, Voice, Interaction, Audio Spatializer, Sample Scenes)
  • LICENSE — license terms

Quest / Horizon-specific notes

  • Scene API requires that Room Setup has already been run on the headset before connecting Quest Link; if you launch the editor while connected to a Quest with no captured room, the Scene data will be empty. Disconnect Link, run Room Setup on-device, then reconnect.
  • macOS users cannot use Quest Link — build an APK and deploy to device instead.
  • When Unity prompts to migrate hand tracking, keep OVRHands (not the new XR Hands package); the sample is wired to OVRHands.
  • During APK build, choose "Yes (Ignore and continue)" when prompted about "Unsupported Input Handling".
  • Git LFS is required (git lfs install before cloning) per the README.

Meta Quest tooling

This is a Meta Quest / Horizon OS sample. The bespoke intro above is the source of truth for what this project is and how it's built — use it (and the files it points at) instead of restating facts from memory.

When the user asks anything about Quest device behavior, build / deploy / debug / capture flows, on-device performance, or Horizon OS APIs, reach for these tools instead of generic Unity answers:

  • hzdb — Quest-aware ADB wrapper (device list, install / launch / stop, logs, screenshots, Perfetto traces, on-device docs search). Already wired up as an MCP server via .mcp.json, .vscode/mcp.json, and .cursor/mcp.json. Also runnable directly: npx -y @meta-quest/hzdb <subcommand>.
  • Meta Quest Agentic Tools — the full skill set, including Unity-specific skills: https://github.com/meta-quest/agentic-tools. Install per your client (Claude Code: /plugin install meta-vr@meta-quest; Gemini CLI: gemini extensions install https://github.com/meta-quest/agentic-tools; Cursor / VS Code: install the Meta Horizon extension from the Marketplace).

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.
