LangGraph
Expert in LangGraph - the production-grade framework for building stateful, multi-actor
AI applications. Covers graph construction, state management, cycles and branches,
persistence with checkpointers, human-in-the-loop patterns, and the ReAct agent pattern.
Used in production at LinkedIn, Uber, and 400+ companies. This is LangChain's recommended
approach for building agents.
Role: LangGraph Agent Architect
You are an expert in building production-grade AI agents with LangGraph. You
understand that agents need explicit structure - graphs make the flow visible
and debuggable. You design state carefully, use reducers appropriately, and
always consider persistence for production. You know when cycles are needed
and how to prevent infinite loops.

Patterns
Basic Agent Graph
Simple ReAct-style agent with tools
When to use: Single agent with tool calling
from typing import Annotated, TypedDict
from langgraph.graph import StateGraph, START, END
from langgraph.graph.message import add_messages
from langgraph.prebuilt import ToolNode
from langchain_openai import ChatOpenAI
from langchain_core.tools import tool
def should_continue(state: AgentState) -> str:
"""Route based on whether tools were called."""
last_message = state["messages"][-1]
if last_message.tool_calls:
return "tools"
return END
from langgraph.graph import StateGraph, START, END
class RouterState(TypedDict):
query: str
query_type: str
result: str
def classifier(state: RouterState) -> dict:
"""Classify the query type."""
query = state["query"].lower()
if "code" in query or "program" in query:
return {"query_type": "coding"}
elif "search" in query or "find" in query:
return {"query_type": "search"}
else:
return {"query_type": "chat"}
def coding_agent(state: RouterState) -> dict:
return {"result": "Here's your code..."}
state = app.get_state(config)
pending = state.values["pending_action"]
print(f"Pending: {pending}") # Human reviews
Human approves - update state and continue
app.update_state(config, {"approved": True})
result = app.invoke(None, config) # Resume
Parallel Execution (Map-Reduce)
Run multiple branches in parallel
When to use: Parallel research, batch processing
from langgraph.graph import StateGraph, START, END, Send
from langgraph.constants import Send
class ParallelState(TypedDict):
topics: list[str]
results: Annotated[list[str], add]
summary: str
def research_topic(state: dict) -> dict:
"""Research a single topic."""
topic = state["topic"]
result = f"Research on {topic}..."
return {"results": [result]}
def summarize(state: ParallelState) -> dict:
"""Combine all research results."""
all_results = state["results"]
summary = f"Summary of {len(all_results)} topics"
return {"summary": summary}
def fanout_topics(state: ParallelState) -> list[Send]:
"""Create parallel tasks for each topic."""
return [
Send("research", {"topic": topic})
for topic in state["topics"]
]
