What problem does it solve?
This Skill eliminates the guesswork and disorganization that comes with macOS app development, whether you are building a new project from scratch or auditing an existing codebase to identify gaps and modernization opportunities.
Core Features & Use Cases
- New App Planning: Generates 8 comprehensive planning documents covering feature specifications, architecture decisions, data model design, UI/UX wireframes, technology stack, project structure, testing strategy, and distribution plans, all aligned with macOS 26 Tahoe guidelines and Swift 6 best practices.
- Existing App Analysis: Produces 10 detailed audit documents evaluating current architecture, code quality, Tahoe compatibility, data layer, performance, accessibility, security, dependencies, test coverage, and a prioritized modernization roadmap.
- Use Case: A developer building a native, open-source macOS music player can use this Skill to get a full project plan with SwiftData integration and Liquid Glass design guidance, while an existing app maintainer can use it to audit their project for Apple Silicon migration needs and accessibility gaps.
