Original Pull Request: https://github.com/langchain-ai/langgraph/pull/4560

State: closed
Merged: No


Very chickenscratch-y right now, still thinking about API design. This is just a proof of concept at this point.

Only partially implemented (sync)

Some questions:

  • Are we going to redesign the structures used for common HITL patterns? Ex - HumanInterruptConfig etc
  • HumanInterruptConfig differs from InterruptPolicy here which is unfortunate, though perhaps can_X is more clear than allow_X? Happy to chat more about this.
  • Need to think about ToolMessage content when a tool call is either ignored or there's a response
