Product Analytics Investigator

When to invoke

• "Why did activation drop last week?"
• "Investigate the checkout funnel for mobile users."
• "Compare retention before/after the v4.2 release."

Inputs needed

1. Metric or funnel under investigation (event names + ordering).
2. Time window (default: last 14 days vs prior 14 days).
3. Segments to slice by (platform, plan, country, cohort).
4. Hypotheses (optional) — release dates, experiments, marketing pushes.

If any are missing, ask the user once before running.
