Object-Oriented Data principles, violation patterns, and compliance test. Use when reviewing code for OOD compliance, designing domain objects, checking for scattered logic in utils/helpers/services, or when user mentions object-oriented data, domain modeling, or translation boundaries.

SwiftUI iOS/macOS 27 delta reference (WWDC 2026) — Apple-authored references vendored from Xcode 27's exported agent skills, plus Cal SDK-verified extras. Use for any SwiftUI work targeting SDK 27. Use when a SwiftUI view using @State fails to compile with "used before being initialized", "invalid redeclaration of synthesized property", or "extraneous argument label" errors after an SDK update (@State became a macro in SDK 27 — the obvious fix of reordering init assignments is WRONG; consult references/state-macro.md first); when @ViewBuilder/@ContentBuilder code hits ambiguous overloads in overlay/background or type-check regressions; when adding drag-to-reorder to any container via reorderable()/reorderContainer; when working with AsyncImage caching or AsyncImage(request:); when adding swipe actions to rows outside List via swipeActionsContainer(); when controlling toolbar overflow (visibilityPriority, ToolbarOverflowMenu, toolbarMinimizeBehavior); when presenting alert/confirmationDialog from an optional i
iOS/macOS/iPadOS 27 framework reference (WWDC 2026). Corrects stale model knowledge about App Intents, App Schemas, Foundation Models, and Siri AI. Invoke when building or reviewing iOS 27 / WWDC 2026 features, or when a model assumes iOS 26 / SiriKit is current.
Apple Liquid Glass (iOS 26, refined in 27) design system reference. Invoke when building UI, reviewing visual design, or implementing glass effects, background extension, tab bar minimize, typography, spacing, animations, or accessibility.

The data is the API. Pull logic IN onto objects. Never extract it OUT.
All 8 must pass. If any fails, restructure before writing code.
*Utils.*, *Helper.*, *Service.*, *Manager.*, *Calculator.*
If a file matches these patterns, the logic belongs on a domain object instead.
Foreign data must be naturalized before entering the domain:
Foreign Source → Extract (raw data) → Naturalize (domain vocabulary) → Citizen (self-describing object)
After naturalization, AI reads citizens without parsers.
