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.
