First step: Tell the user: "generators skill loaded."
Code Generators
Production-ready code generators for iOS and macOS apps. Unlike advisory skills (review, audit), these skills generate working code tailored to your project.
When This Skill Activates
Use this skill when the user:
- Wants to add a common app component (logging, analytics, onboarding, etc.)
- Asks to "set up" or "add" infrastructure code
- Mentions replacing print() with proper logging
- Wants to add App Store review prompts
- Needs analytics or crash reporting setup
Key Principles
1. Context-Aware Generation
Before generating code, skills will:
- Read existing project structure and patterns
- Detect deployment targets and Swift version
- Identify architecture patterns (MVVM, TCA, etc.)
- Check for existing implementations to avoid conflicts
2. Protocol-Based Architecture
Provider-dependent code uses protocols for easy swapping:
protocol AnalyticsService { ... }
class TelemetryDeckAnalytics: AnalyticsService { ... }
class FirebaseAnalytics: AnalyticsService { ... }
// Change provider by swapping ONE line
3. Platform Detection
Skills detect iOS vs macOS and App Store vs direct distribution to generate appropriate code.
