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
- +支持多种主流LLM模型（ChatGPT、LLaMa、Alpaca）且提供统一接口
- +强大的链式提示系统能够处理复杂的多步骤任务
- +内置向量存储集成为模型提供长期记忆和知识库支持
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
- -仅支持Rust语言，限制了非Rust开发者的使用
- -相对较新的项目，生态系统和社区支持可能不如成熟的Python替代方案
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
- •构建需要多步骤推理的智能客服聊天机器人
- •开发具有长期记忆和专业知识的AI代理系统
- •创建能够执行复杂任务的自动化工具链
