LangChain React agent
A LangChain ReAct agent is an agent pattern that alternates between reasoning and actions. Instead of producing only a final answer, it can plan intermediate steps and call tools when they are needed to finish the task.
In practice, a ReAct agent works well for workflows where the system must decide which tool to use next (for example: search, retrieval, code execution, or other application-defined functions). It still depends on the tools and environment you provide, so the “agent” behaviour is bounded by what the application enables.
