What problem does it solve? Starting a macOS app without a clear plan leads to architecture mistakes, scope creep, and rework, while auditing an existing codebase manually is slow and inconsistent. This Skill produces structured planning and analysis documents covering architecture, data models, UI/UX, testing, and distribution. ## Core Features & Use Cases - New App Planning: Generates 8 planning documents covering feature specification, architecture decisions (SwiftUI vs AppKit, MVVM), SwiftData data models, UI/UX wireframes, tech stack, project structure, testing strategy, and distribution plan. - Existing App Analysis: Produces 10 audit documents covering architecture, code quality (SOLID/DRY), Liquid Glass and HIG compliance, performance, accessibility, security, dependencies, test coverage, and a modernization roadmap. - Use Case: You have an idea for a menu-bar productivity app. Ask the Skill to plan it, and receive a complete document set including SwiftData schema design, SwiftUI navigation structure, and a Mac App Store distribution checklist. ## Quick Start Ask the assistant to plan a new macOS app or analyze an existing macOS project, then answer its questions about requirements and goals.
