app-intents
Writes and reviews Swift App Intents code that exposes app actions and data to Siri, Shortcuts, Spotlight, widgets, Control Center, and Apple Intelligence. Use when adding AppIntent, AppEntity, OpenIntent, AppShortcutsProvider, EntityQuery, Focus Filters, AssistantEntity/AssistantIntent schemas, on-screen awareness, LongRunningIntent/CancellableIntent, EntityCollection, SyncableEntity, AppIntentsTesting, or when wiring SwiftData/networked data into intents.
widgets
Writes and reviews SwiftUI WidgetKit code for Home Screen, Lock Screen, StandBy, and watch widgets - timeline providers and reload policies, StaticConfiguration / AppIntentConfiguration, user-configurable widgets, widget families and sizing, accented/tinted rendering modes, interactive widgets and Controls (Control Center), Live Activities and the Dynamic Island, Smart Stack relevance, push-updated widgets, and visionOS / CarPlay / macOS surfaces. Use when building a widget extension, a timeline provider, a Lock Screen or accessory widget, a watch complication, an interactive button/toggle widget, a Control Center control, a Live Activity, or fixing a widget that won't update or render correctly in tinted mode.
background-execution
Writes and reviews Swift code for background execution on Apple platforms - BGTaskScheduler (app refresh, processing, continued processing), beginBackgroundTask assertions, background URLSession downloads/uploads, silent and VoIP push, background modes (audio, location, BLE), the SwiftUI .backgroundTask modifier, and macOS schedulers. Use when scheduling deferred work, finishing work after the app backgrounds, transferring files in the background, waking the app via push, or debugging background tasks that never run.
swift-format-style
Writes and reviews Swift FormatStyle code, replacing legacy Formatter subclasses and C-style String(format:) with modern .formatted() APIs. Use when formatting numbers, dates, durations, measurements, lists, names, byte counts, or URLs.
observability
Writes and reviews Swift observability code on Apple platforms - unified logging (Logger, OSLog, privacy redaction, log levels and persistence), signposts and Instruments, activity tracing, MetricKit metrics and diagnostics (launch, hangs, crashes, OOM, disk writes), crash reports and symbolication, OSLogStore log export, Xcode Organizer, and shipping telemetry to your own backend or third-party SDKs. Use when adding logging, instrumenting performance, wiring MetricKit, diagnosing production crashes or hangs, exporting logs for support, or choosing between print, Logger, signposts, and analytics SDKs.
agent-gauntlet
Multi-stage agent pipeline for feature development with deterministic quality gates - a specifier writes Gherkin acceptance criteria, a coder implements to green tests, a cleaner refactors until a complexity+coverage gate passes, a hardener kills surviving mutants via mutation testing. Use when implementing a user story with verifiable quality, when asked to "run the gauntlet", or when setting up quality gates for agent-written code.
