Human-in-the-Loop Agents in Python: Approval Workflows with LangGraph

Description

Safer agents pause for human approval, then resume without losing state — the core human-in-the-loop pattern for risky actions. Learn a simple pause–review–resume flow that prevents accidental emails, costly API calls, and unsafe database writes while preserving traceability. Hands-on demo uses LangGraph and MemorySaver in Python to stream, interrupt, and resume runs with app.stream/app.resume.
