Does this skill support both client and server tracking?

Yes, it provides specific patterns for client-side initialization via posthog-js and server-side event capture using posthog-node.

Can I use this for feature flags as well as analytics?

Absolutely. PostHog is a unified platform, and this skill configures the provider and client needed for both analytics and feature flag management.

What coding standards does the generated setup follow?

All code follows the project-specific CLAUDE.md conventions, including kebab-case filenames, named exports, and strict import ordering.

How does it handle event loss in serverless functions?

The skill implements critical patterns like captureImmediate() and explicit flush() calls to ensure data is sent before serverless environments terminate.
