1. Define a node in the LangGraph that requires human intervention.
2. Use `interrupt(value)` to pause the graph's execution and surface the `value` to the caller.
3. Implement a mechanism to capture the human's response.
4. Resume the graph's execution using `Command(resume=value)`, providing the human's response as input.
5. Handle the resumed execution, ensuring that side effects before the interrupt are idempotent.
6. Process the human's input and update the graph's state accordingly.
