How does it ensure feature parity across platforms?

It utilizes a dedicated integration and validation phase that includes a parity matrix and cross-platform testing reports to identify and fix discrepancies in functionality or design.

Does this skill favor cross-platform frameworks like Flutter?

This skill is flexible; it supports both shared logic approaches like Kotlin Multiplatform and native-first implementations (SwiftUI/Compose) to ensure the best possible performance on every target device.

Can I use this with an existing API?

Yes, while the skill defaults to an API-first design phase for new features, it can be configured to skip Phase 1 and implement features based on your existing backend specifications.

Which desktop frameworks are supported?

The workflow specifically includes prompts and optimization strategies for Tauri 2.0 and Electron, allowing for seamless porting of web codebases to desktop environments.

Mobile Development

Orchestrates parallel development across web, mobile, and desktop platforms using an API-first architecture and shared business logic patterns.

This skill streamlines the process of building synchronized features across diverse platforms by coordinating specialized agents for API design, UI/UX consistency, and native implementation. By establishing shared contracts and domain models upfront, it ensures feature parity while allowing for platform-specific optimizations like SwiftUI for iOS, Jetpack Compose for Android, and React for Web. It is an essential tool for engineering teams needing to scale features rapidly across ecosystems while maintaining high-performance native experiences and a single source of truth for business logic.
