Analyzes Mixpanel data with Python, the mixpanel_headless library, and pandas. Use when the user asks about their Mixpanel data, such as event trends, DAU/WAU/MAU, funnels, retention and churn, user paths, user profiles, cohorts, a user's tracked event history (activity feed), segment comparisons, revenue, feature adoption, or experiment results. Also use to explore a project's events and properties, build a custom property or cohort, share a query as a report link, read or write business context, or manage entities such as cohorts, feature flags, experiments, alerts, annotations, webhooks, Lexicon definitions, and other governance objects, or when code runs mixpanel_headless queries or `mp query` / `mp inspect`. Do not use for adding tracking to an app's source code, for what a specific user did on screen (use session-replay), for building or editing dashboards (use dashboard-expert), for logging in, credentials, or switching accounts (use auth), or for installing the library (run /mixpanel-headless:setup).
