Add Feature Flags

Use this skill when the user asks to add feature flags, feature toggles, gradual rollouts, or A/B testing.

Option A: PostHog Feature Flags (Recommended)

1. Install PostHog if not already present:

   npm install posthog-js
   

2. Use feature flags in code:

   import { useFeatureFlagEnabled } from "posthog-js/react";
   
   function MyComponent() {
     const showNewFeature = useFeatureFlagEnabled("new-checkout-flow");
