Guides porting existing Android 2D apps to Meta Quest and Horizon OS — input adaptation, panel layout, and design requirements. Use when adapting a mobile Android app for Quest.
Upgrades Meta Quest apps to newer Horizon OS SDK versions — migration guides, deprecated API replacements, changelog. Use when updating SDK versions or fixing deprecated API warnings.
Builds WebXR experiences for Meta Quest and Horizon OS using the Immersive Web SDK (IWSDK) — ECS architecture, Three.js integration, spatial UI. Use when creating web-based VR/MR apps for Quest Browser.
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.
