langgraph human in the loop
What it does
- interrupt(value) — pauses execution, surfaces a value to the caller
- Command(resume=value) — resumes execution, providing the value back to interrupt()
- Checkpointer — required to save state while paused
- Thread ID — required to identify which paused execution to resume
- Use upsert (not insert) operations before interrupt()
- Use check-before-create patterns
- Place side effects after interrupt() when possible
