Scaffolds new Meta Quest and Horizon OS projects with recommended settings for Unity, Unreal, Android/Spatial SDK, or WebXR. Use when creating a new Quest app from scratch.

Analyzes Meta Quest and Horizon OS VR performance using Perfetto traces — frame timing, CPU/GPU bottlenecks, render pass analysis. Use when profiling frame drops, jank, or thermal issues on Quest devices.

For 3P / EXTERNAL developers: guides interactive Horizon Platform SDK (PSDK) integration for Meta Quest and Horizon OS Android/Kotlin apps — analyzes the codebase, recommends public platform features, plans the integration, and validates on device. Uses the external toolchain (Gradle, metavr, a developers.meta.com / Rocksteady App ID). For 1P apps inside fbsource (buck, Chesterfield/ni, adb), use psdk_1p_onboarding_agent instead.

MANDATORY pre-flight check before answering any question or writing any code related to Meta Quest VR headsets (Quest 2, Quest 3, Quest 3S, Quest Pro) or apps that target them. Forces verification against authoritative Meta sources via the metavr CLI / metavr MCP tools BEFORE relying on training-data knowledge. Counters the failure mode where agents answer Quest-related questions from stale memory and ship deprecated APIs, broken Android manifests, and store-rejected builds. Loads automatically when the user is in a Quest project (any reference to Oculus / Meta Quest / Horizon OS, Unity OVR or Meta XR packages, com.meta.* / com.oculus.* package IDs, Quest-targeted AndroidManifest, .meta files, or developers.meta.com / developer.oculus.com URLs).

Profiles Meta Quest and Horizon OS application CPU performance using simpleperf — workload classification, CPU hotspot recording, kernel overhead measurement. Use when diagnosing whether an app is CPU-bound, memory-bound, or I/O-bound on Quest devices.

Builds spatial Android apps for Meta Quest and Horizon OS with Meta Spatial SDK — ECS architecture, 2D panels, 3D objects, hybrid experiences. Use when creating Kotlin-based spatial applications.

Guides shipping a web app to the Meta Quest and Horizon OS Store as a PWA/TWA — both 2D windowed panels and immersive WebXR/VR. Covers building the web app (IWSDK for WebXR, any responsive PWA for 2D), Vercel deploy, web app manifest + icons, the WebXR-only auto-enter-session step, choosing 2D vs immersive mode in @meta-quest/bubblewrap-cli, keystore/Digital-Asset-Links, and ovr-platform-util Store upload. Use before any IWSDK/WebXR build, PWA packaging, bubblewrap, or Horizon Store upload work.

Guides end-to-end Meta Quest and Horizon OS app submission to the Meta Horizon Store — build validation, store-readiness checks, asset preparation, upload, and submission tracking. Use when preparing a Quest app for store publishing.

Reviews Unity code targeting Meta Quest and Horizon OS for performance issues, rendering best practices, and common VR pitfalls. Use during code review or when diagnosing Quest performance problems in Unity projects.

Drive ARKit-blendshape-rigged head/face models in Unity with the wearer's facial expressions on Meta Quest via Meta Movement SDK (face tracking + A2E). Use when a user has an FBX with the 52 ARKit blendshapes (any prefix, _L/_R suffixes) and wants it to animate from face tracking on Quest Pro / Quest 3 / Quest 3S.

Meta XR Mixed Reality Utility Kit (MRUK) (com.meta.xr.mrutilitykit) for Unity XR development. Use when working with Scene API data (rooms, walls, floors, furniture), spawning prefabs on scene anchors, placing virtual objects in the real world, world locking to prevent anchor drift, raycasting against room geometry, generating NavMesh from scene data, environment depth raycasting for instant placement without scanning, Passthrough Camera Access (PCA), trackable detection (keyboards, QR codes), destructible scene meshes, space maps, room sharing for multiplayer, or any MR scene-aware feature.

Set up and tweak Meta Movement SDK (MSDK) retargeting for a character model. Use this whenever the user wants to retarget a humanoid FBX/prefab for Meta Quest body tracking, generate a retargeting config, or hand-edit the resulting `<asset>.json` (fix known-joint mappings, exclude joints from auto-mapping, rename target joints, adjust per-joint mapping weights, change a mapping behavior to twist/childAlignedTwist, edit T-pose values). The headless entry point is `Meta.XR.Movement.Editor.MSDKUtilityEditor.RunDefaultRetargetingSetup(GameObject asset)` — call it via Unity MCP first, then hand-edit if needed. **Skip** if the user is editing runtime retargeting code, the source `OVRSkeletonData.json`, or non-MSDK files.

Meta Quest Passthrough Camera Access (PCA) for Unity — access the forward-facing RGB cameras on Quest 3 / Quest 3S to feed Computer Vision and Machine Learning pipelines. Use when capturing the passthrough camera image/texture, reading the camera pose and intrinsics, projecting camera pixels into world space via `PassthroughCameraAccess.ViewportPointToRay`, wiring camera frames into ML/CV models, or reasoning about resolution, permissions, vendor tags, and the pinhole/principal-point model. For projecting the image onto a flat world-space surface (frustum-slice quad / image-plane overlay) see references/principal-point-offset.md; for placing 2D ML detections as world-space 3D bounding boxes see references/detection-bounding-boxes.md. Skip if the user only wants to cast the user's POV (use the Media Projection API instead) or is doing screen-space-only overlays.

Debugs Meta Quest and Horizon OS VR/MR applications using the metavr CLI — view logs, capture screenshots, diagnose common issues. Use when troubleshooting crashes, errors, or unexpected behavior on Quest devices.

Sets up the Meta XR Simulator for testing Meta Quest and Horizon OS apps without a physical device. Use when configuring device-free testing for Unity or Unreal projects.

Provides the complete metavr (Meta VR CLI) reference for Meta Quest and Horizon OS development — installation, device setup, command discovery, MCP server mode, documentation search, app deployment, device testing setup, audio control, screenshots, and performance analysis. Use when the user needs to install metavr, asks what commands are available, needs CLI syntax help, or wants to know what metavr can do.

Build and sideload Android apps for Meta Portal devices (Portal, Portal+, Portal Mini, Portal Go, Portal TV) using metavr. Use when targeting Portal hardware — covers ADB enablement, the no-GMS constraint, manifest/launcher intent-filter requirements, icon density quirks (PNG-only, mipmap-xxxhdpi), the Smart Camera SDK, and the gradle + `metavr adb` build/deploy/debug loop. Auto-load when the user mentions "Portal" device, targets `minSdkVersion` 28-29 for a tabletop/TV form factor, or works with the `com.facebook.portal` package.
