Cross-Platform App Port

Overview

Rebuild the product for the target platform. Preserve verified behavior, data semantics, and visual intent. Do not translate source code line by line or reproduce source technical debt without a documented reason.

The source is the product reference. The target platform and target repository define the implementation conventions.

When to Use

Use this skill for:

• iOS to Android or Android to iOS ports
• Web, Electron, React Native, or Flutter to native ports
• Native UI framework migrations such as UIKit to SwiftUI or Views to Compose
• One feature, one flow, a subsystem, or a full application
• Existing ports that need feature, behavior, or quality parity

Do not use it for a greenfield app with no source product, a cosmetic redesign with intentionally different behavior, or automatic source-to-source syntax translation.
