+$ARGUMENTS
+
+Instructions:
+
+- Use the `ios-swift-answering` skill if available.
+- Use `swiftui-xflow-review` if the question touches SwiftUI, XFlow, UIKit bridge removal, modal presentation, lifecycle, or backend-driven UI.
+- Use `ios-testing-strategy` if the question touches tests or validation.
+- If current Apple API behavior matters, verify against official Apple or Swift documentation before making strong claims.
+- Contextualize the answer to Fidelity only when it materially changes the recommendation.
+- Separate current best practice from project-safe recommendation when they differ.
+
+Return:
+
+1. Recommendation
+2. Project-specific caveats
+3. Validation or follow-up checks
