Pros

    • +Durable execution ensures agents automatically resume from exactly where they left off after failures or interruptions
    • +Comprehensive memory system with both short-term working memory for ongoing reasoning and long-term persistent memory across sessions
    • +Seamless human-in-the-loop capabilities allow for inspection and modification of agent state at any point during execution

    Cons

      • -Low-level framework requires more technical expertise and setup compared to high-level agent builders
      • -Graph-based agent design paradigm may have a steeper learning curve for developers new to agent orchestration
      • -Production deployment complexity may be overkill for simple chatbot or single-turn use cases

      Use Cases

        • •Long-running autonomous agents that need to persist through system failures and operate over days or weeks
        • •Complex multi-step workflows requiring human oversight, approval, or intervention at specific decision points
        • •Stateful agents that must maintain context and memory across multiple sessions and interactions
