What problem does it solve?

This skill helps developers and product teams understand exactly how PostHog is configured on a page and what data is captured, by inspecting the global posthog object, network requests, and loaded scripts.

Core Features & Use Cases

  • Full implementation audit: Verify version, API host, tokens, autocapture, session recording, persistence, and load order.
  • Feature flag inspection: Identify loaded flags and their values to confirm feature rollout.
  • Session & identity analysis: Retrieve distinct IDs, session IDs, and device identifiers to ensure correct tracking.
  • Network & script analysis: Inspect network requests to PostHog endpoints and detect loaded PostHog scripts.
  • Issue detection & reporting: Surface configuration issues and common misconfigurations with clear summaries.
  • Script loading analysis: Determine how PostHog is loaded (CDN, self-hosted, or bundled) and detect multiple instances.

Quick Start
