# Feature Flags Generator Generate a complete feature flag infrastructure with typed flag definitions, protocol-based providers (local, remote, composite), SwiftUI environment integration, an `@Observable` manager, and a debug menu for toggling flags at runtime. ## When This Skill Activates Use this skill when the user: - Asks to "add feature flags" or "add feature toggles" - Mentions A/B testing or gradual rollouts - Asks about Firebase Remote Config or similar remote configuration - Wants to disable features without shipping an app update - Mentions "kill switches" or "feature gates" - Wants to control features remotely for a subset of users - Asks for a debug menu to toggle features during development ## Pre-Generation Checks ### 1. Project Context Detection - [ ] Check for existing feature flag implementations - [ ] Check for Firebase Remote Config or third-party flag SDKs - [ ] Identify source file locations (Sources/, App/, or root) - [ ] Verify minimum deployment target (iOS 17+ / macOS 14+ for @Observable) ### 2. Conflict Detection Search for existing feature flag code: ``` Glob: **/*FeatureFlag*.swift, **/*FeatureToggle*.swift, **/*RemoteConfig*.swift Grep: "FeatureFlag" or "FeatureToggle" or "RemoteConfig" or "isFeatureEnabled" ``` If existing feature flag code is found: - Ask whether to replace or extend the existing implementation - Check for flag names or enum cases that could conflict If a third-party SDK (Firebase, LaunchDarkly, etc.) is detected: - As...
