Time travel Guide
Time travel Review We discussed motivations for human-in-the-loop: (1) Approval - We can interrupt our agent, surface state to a user, and allow the user to accept an action (2) Debugging - We can rewind the graph to reproduce or avoid issues (3) Editing - You can modify the state We showed how breakpoints can stop the graph at specific nodes or allow the graph to dynamically interrupt itself. Then we showed how to proceed with human approval or directly edit the graph state with human feedback. Goals Now, let's show how LangGraph supports debugging by viewing, re-playing, and even forking from past states. We call this time travel.

How to use Time travel
Time travel is a autonomous loop agent built on the LangGraph framework. Set it up from the source repository, configure your model credentials, and invoke it for tasks that match its description. Review the safety profile below before running it against production data or systems.
