+Example: Rerunning saved agent history
+
+This example shows how to:
+1. Run an agent and save its history (including initial URL navigation)
+2. Load and rerun the history with a new agent instance
+
+Useful for:
+- Debugging agent behavior
+- Testing changes with consistent scenarios
+- Replaying successful workflows
+
+Note: Initial actions (like opening URLs from tasks) are now automatically
+saved to history and will be replayed during rerun, so you don't need to
+worry about manually specifying URLs when rerunning.
