What is LangGraph used for in Claude Code?

LangGraph is used to build stateful, multi-actor applications with LLMs, specifically managing loops and shared state across different execution nodes in an agentic workflow.

Does this skill support persistent memory?

Yes, it includes implementation patterns for checkpointing using Memory, SQLite, and Postgres to allow agents to pause and resume tasks across different sessions.

Can I implement human approval steps with this skill?

Absolutely. The skill provides code patterns for using the interrupt() function to pause execution and wait for human feedback or approval before continuing.

Is it compatible with Pydantic for state validation?

Yes, the skill covers defining state schemas using both TypedDict and Pydantic models to ensure robust data validation throughout your graph execution.

Implements stateful agent graphs and multi-actor workflows using the LangGraph framework.

소개

This skill empowers developers to architect, build, and maintain complex AI agent systems using LangGraph's graph-based architecture. It provides specialized guidance on defining shared state schemas, implementing persistent checkpointing for long-running tasks, handling human-in-the-loop interruptions, and managing multi-agent fanning or merging patterns. Whether you are building simple chat agents or intricate hierarchical multi-actor systems, this skill ensures best practices for state management and execution flow are followed within the Claude Code environment.
