AgentExecutor
An agent executor class in legacy versions of LangChain, responsible for running the agent loop. It was deprecated and removed in LangChain 1.x.

Common open-source Agent Harness implementations include LangChain's AgentExecutor, AutoGPT's main loop, and the command execution layers of various Coding Agents.
传统 AgentExecutor 的状态管理是隐式的，循环和分支难以表达，人机协同支持不足，调试困难。
Compared to LangChain's early AgentExecutor, LangGraph transforms control flow from a black box internal to the framework into a graph structure that developers can explicitly define, making patterns such as interruption, rollback, and human-machine collaboration possible.
When using LangChain's AgentExecutor to execute tasks involving multiple tool calls, the order of the serialized tool-call list may differ across two runs even if they are functionally identical.
