//! Prebuilt components for LangGraph agents.
//!
//! This crate provides prebuilt components for common agent patterns:
//!
//! - **Message types**: `Message`, `ToolCall`, `MessageContent`
//! - **Traits**: `BaseTool`, `BaseChatModel` for tool and model integration
//! - **ToolNode**: Executes tool calls from AI responses
//! - **create_react_agent**: Builds a ReAct (Reasoning + Acting) agent graph
//! - **tools_condition**: Routing function for tool-calling agents
