Why is the 'defaults' date 2026-01-30 used in the config?

Using a fixed defaults date ensures your implementation uses PostHog's latest stable recommended behaviors for SPA tracking and session management without breaking changes.

Can I use this for serverless environments like Vercel?

Absolutely. It includes specific patterns like `captureImmediate()` and explicit flushing to prevent lost events in transient serverless execution contexts.

Does this skill handle both client and server-side setup?

Yes, it provides optimized patterns for both `posthog-js` for browser environments and `posthog-node` for server-side or API route tracking.

Does this setup support PostHog feature flags?

Yes, by initializing the core PostHog SDKs correctly, you'll be fully prepared to use feature flags, experiments, and remote configuration across your app.
