Design, implement, and debug WebGPU applications, GPU compute pipelines, and WGSL shaders. \n \n Covers WebGPU initialization, device setup, compute and render pipelines, shader authoring, and GPU/CPU synchronization strategies \n Includes architecture patterns for modular passes, phase-based simulation, spatial indexing, and capability fallback handling \n Provides guidance on performance optimization, safe readback strategies, and debugging practices for rendering, compute, ML workloads, and p

NoSQL document database with real-time sync, offline persistence, and security rules. \n \n Supports both Client SDK (authenticated users) and Admin SDK (server-side, bypasses rules) with modular v9+ API for CRUD, queries, transactions, and batch operations \n Real-time listeners via onSnapshot() for documents and collections; requires manual unsubscribe to prevent memory leaks and connection limits \n Compound queries with multiple filters, range queries, array operations, and pagination via cu

Build map and location features for iOS 17+ using SwiftUI MapKit and modern CoreLocation async APIs. \n \n Supports SwiftUI Map views with markers, annotations, polylines, polygons, and circles; includes camera positioning, style options, and interaction modes \n Provides CLLocationUpdate.liveUpdates() async stream for location tracking and CLMonitor for geofencing with up to 20 monitored conditions \n Covers geocoding (forward and reverse), local search with autocomplete via MKLocalSearchComple

Fetch, create, update, and pick contacts from the user's Contacts database using CNContactStore, CNSaveRequest, and CNContactPickerViewController. Targets Swift 6.3 / iOS 26+.

Read-only GitHub issue and PR analyzer that spawns parallel background tasks for evidence-backed triage reports. \n \n Fetches all open issues and PRs, classifies each by type (bug, feature, question, etc.), and spawns one quick background subagent per item for parallel analysis \n Every factual claim in reports requires a GitHub permalink to specific code lines or commits; unverifiable statements are marked [UNVERIFIED] and carry no weight \n Generates individual markdown reports to /tmp/{datet

This skill implements Clerk in native Android projects by following current clerk-android SDK and docs patterns.

Imperative modal dialog creation using createModal from @lobehub/ui. \n \n Eliminates the need for open state management by calling a function directly instead of rendering a declarative component \n Provides useModalContext hook within modal content to access close() and setCanDismissByClickOutside() methods \n Supports configuration for fullscreen mode, footer content, width, and destroy-on-hidden behavior \n Requires separate i18n handling: useTranslation hook in content components, direct i1
