summary

Pause graph execution for human review, approval, or validation, then resume with their input.

  • Requires three components: a checkpointer (InMemorySaver or PostgresSaver), a thread ID in config, and JSON-serializable interrupt payloads
  • interrupt(value) pauses and surfaces data; Command(resume=value) resumes and returns that value to the paused node
  • All code before interrupt() re-executes on resume, so side effects must be idempotent (use upsert, not insert)
  • Supports approval workfl
