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.

How to Use

1. User requests a component (e.g., "add logging to my app")
2. Read the relevant skill's SKILL.md
3. Run pre-generation checks (conflicts, deployment target, etc.)
4. Ask configuration questions via AskUserQuestion
5. Generate code from templates, adapting to project context
6. Provide integration instructions

Output Format

After generation, always provide:

• Files created (with full paths)
• Integration steps (how to wire into existing code)
• Required capabilities (entitlements, dependencies)
• Testing instructions (how to verify it works)
