Function create_react_agent_with_options 

pub fn create_react_agent_with_options(
    model: Arc<dyn ChatModel>,
    tools: Vec<Arc<dyn Tool>>,
    options: ReactAgentOptions,
) -> Result<CompiledGraph<MessageState>, SynapseError>

Create a prebuilt ReAct agent graph with additional configuration options.

This is the extended version of create_react_agent that accepts a ReactAgentOptions struct for configuring checkpointing, interrupts, and system prompts.

The graph has two nodes:

• “agent”: calls the ChatModel with messages and tool definitions
• “tools”: executes any tool calls from the agent’s response

Routing: if the agent returns tool calls, route to “tools”; otherwise route to END.

Example

use std::sync::Arc;
use synaptic_graph::{create_react_agent_with_options, ReactAgentOptions, MemorySaver};

let options = ReactAgentOptions {
    checkpointer: Some(Arc::new(MemorySaver::new())),
    system_prompt: Some("You are a helpful assistant.".to_string()),
    interrupt_before: vec!["tools".to_string()],
    ..Default::default()
};

let graph = create_react_agent_with_options(model, tools, options)?;
