Use when matching virtual lighting to the environment, informing custom stereo rendering, coaching device fit, or tuning foveated field of view.

Build and debug ARKit reference and marker tracking providers for visionOS 27: ImageTrackingProvider, ObjectTrackingProvider, BarcodeDetectionProvider, and AccessoryTrackingProvider. Use when anchoring to known images, tracked 3D reference objects, barcodes, or supported accessories.

Implement immersive and spatial video experiences on Apple Vision Pro (visionOS 27), including AVKit AVExperienceController, RealityKit VideoPlayerComponent setup, Apple Projected Media Profile (APMP), portal/progressive/full immersive viewing modes, transitions and events, comfort mitigation, and Apple Immersive Video authoring workflows.

Build USDKit runtime editing flows on visionOS 27, macOS 27, or iOS 27. Use when Swift code imports USDKit, opens or creates USDStage and USDLayer values, edits USDPrim attributes, observes USDStage.ObjectsDidChange, exports runtime USD packages, or bridges live stages through RealityKit USDStageComponent.

Enforce repository coding standards for Swift 6.2 strict concurrency, actor isolation, @Observable models, SWIFT_APPROACHABLE_CONCURRENCY, @concurrent functions, and modern Swift APIs across visionOS app code. Use when reviewing, writing, or migrating Swift code in this plugin's scope.

Design and implement visionOS 27 SwiftUI scenes that integrate RealityKit content. Use when building spatial UI with RealityView, Model3D, attachments, volumetric windows, ImmersiveSpace, spatial gestures, windowing, spatial layout, or when choosing SwiftUI vs RealityKit APIs for 3D presentation.

Build SwiftUI Chart3D and Swift Charts 3D visualizations for visionOS 27 and Apple platforms. Use when implementing Chart3D, SurfacePlot, 3D PointMark, RuleMark, RectangleMark, Chart3DPose, 3D chart scales, axis labels, camera projection, or spatial data-visualization interactions.

Build and debug HandTrackingProvider on visionOS 27. Use when implementing hand anchors, hand joint transforms, custom hand gestures, hand-driven interactions, hand visualizations, or troubleshooting hand-tracking authorization, support, and lifecycle behavior.

Implement and debug RealityKit animation, character controllers, skeletal poses, IK, body tracking, blendshapes, animation graphs, retargeting, root motion, navigation, behavior trees, collision, physics bodies, joints, forces, particles, compute simulations, and cloth on visionOS 27. Use when a RealityKit task is primarily about motion, character behavior, physical simulation, hit-test collision shape details, particle simulation, or animation/physics troubleshooting.

Build and debug WidgetKit widgets for Apple Vision Pro (visionOS), including mounting styles (elevated/recessed), textures (glass/paper), proximity-aware layouts via LevelOfDetail, interactive widgets with AppIntents, widget rendering modes (accented/fullColor), and timeline update troubleshooting. (visionOS widgets are pinned spatial objects, not watch complications.)

Build and debug ARKit camera access providers for visionOS 27: CameraFrameProvider and CameraRegionProvider. Use when accessing camera frame streams, region-scoped camera content, custom computer-vision pipelines, or troubleshooting camera-access authorization, entitlement, enterprise, format, and support issues.

Route RealityKit work on visionOS 27 and handle core entity/component basics, RealityView scene setup, asset loading, input targets, SwiftUI attachments, anchoring, portals, synchronization, and USDStage bridge usage. Use for general RealityKit triage, choosing documented components, loading Reality Composer Pro, USD, USDZ, or .reality content, and deciding whether to hand off to realitykit-rendering-materials, realitykit-animation-physics, realitykit-audio-spatial, realitykit-ecs-systems, spatial-preview-developer, usdkit-runtime-developer, usd-editor, shadergraph-editor, ARKit, SwiftUI, or build-debug skills.

Implement and debug RealityKit rendering, materials, lighting, cameras, visual effects, post-processing, render cost controls, Gaussian splats, decals, lightmaps, probes, LOD, and occlusion on visionOS 27. Use when a RealityKit task is primarily about visual appearance, mesh/material display, lights, shadows, tone mapping, bloom, camera projection, rendering performance, or choosing rendering components instead of animation, audio, interaction, or custom ECS behavior.

Guide for modifying USD ASCII (.usda) files and command-line USD workflows, including prims, properties, composition arcs, variants, transforms, usdcat, usdchecker, usdrecord, usdtree, usdzip, and usdedit. Use when editing or reviewing .usda files by hand, validating USD/USDZ assets, or working in an asset pipeline outside runtime Swift USDKit.

Guide for creating and structuring skills with consistent formatting, clear documentation, and proper reference organization. Use when creating new skills or updating existing skill documentation.

Author, load, and troubleshoot Reality Composer Pro Shader Graph materials for RealityKit on visionOS. Use when building Shader Graph materials, exposing promoted inputs for runtime control, debugging exported USD and MaterialX interop, or building shader graphs programmatically in Swift on visionOS 27.

Build, integrate, and troubleshoot SharePlay GroupActivities features for visionOS 27, including GroupActivity definitions, activation flows, GroupSession lifecycle, messaging and journals, ShareLink and SharePlay UI surfaces, and spatial coordination.

Design, implement, and debug custom RealityKit components, systems, ECS queries, component registration, update loops, Codable component state, and per-frame multi-entity behavior on visionOS. Use when documented RealityKit components do not represent the needed state or behavior, when behavior spans multiple entities, or when a task needs custom System and Component architecture instead of SwiftUI view logic.

Router for ARKit features on visionOS 27, including ARKitSession setup, authorization, provider selection, anchor processing, and RealityKit integration. Use when choosing an ARKit provider set, combining multiple ARKit providers, or troubleshooting shared ARKit lifecycle behavior before routing to focused provider skills.

Implement and debug RealityKit spatial audio, ambient audio, channel audio, audio libraries, audio mix groups, reverb, grouped playback, and acoustic simulation on visionOS 27. Use when a RealityKit task is primarily about placing sound in 3D, loading or organizing audio resources, controlling channel or ambient playback, mixing groups, room acoustics, or audio behavior tied to RealityKit entities.

Choose and refactor visionOS app architecture across surfaces, scene boundaries, state ownership, and file layout. Use when deciding window vs volume vs immersive space, splitting a feature across scenes, cleaning up a monolithic spatial root, or defining the ownership map before implementing SwiftUI or RealityKit details.
