CRITICAL: Before Using This Skill
All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering,
import type, named constants)
(You MUST initialize posthog-js only in a client/browser context - it requires browser APIs like window and localStorage)
(You MUST call posthog.shutdown(), posthog.flush(), or use captureImmediate() after server-side event capture to prevent lost events)
(You MUST use defaults: '2026-01-30' for automatic SPA page tracking and latest recommended behaviors)
