build-macos-apps

This skill provides an expert-level CLI environment for developing high-performance native macOS software. By stripping away the visual overhead of Xcode, it enables developers to focus on architecture, code quality, and verifiable outcomes using industry-standard tools like xcodebuild, Swift, and AppKit. It is designed for developers who prefer terminal-based control, automated testing, and precise lifecycle management from scaffolding to deployment.

• Full development lifecycle support including project scaffolding, debugging, testing, performance optimization, and final App Store or manual release preparation.

• Professional-grade architecture patterns leveraging SwiftUI and AppKit, with deep support for dependency injection, concurrency, and modular system integration.

• Automated verification loops that force the "Prove, Don't Promise" principle, ensuring that builds, tests, and UI launches are validated in the terminal before any report is delivered to you.

• Support for macOS-specific features including share extensions, system APIs, and menu bar application development using modern Swift observability and concurrency patterns.

• This agent acts as a lead developer who implements and verifies changes in small, atomic steps to maintain a working state at every stopping point.

• Input your requirements in plain language, and the agent translates them into executable Swift code, test suites, and build scripts.

• The workflow prioritizes correctness and performance, using tools like the profiler for optimization and automated test suites for logic verification.

• While the toolchain is CLI-focused, it adheres to native macOS development standards, ensuring compatibility with the broader Apple ecosystem.
