LangGraph Patterns Expert Skill

Purpose

Master LangGraph for building production-ready AI agents with fine-grained control, checkpointing, streaming, and complex state management.

Core Philosophy

LangGraph is: An orchestration framework with both declarative and imperative APIs focused on control and durability for production agents.

Not: High-level abstractions that hide complexity - instead provides building blocks for full control.

Migration: LangGraph replaces legacy AgentExecutor - migrate all old code.

The Six Production Features

1. Parallelization - Run multiple nodes concurrently
2. Streaming - Real-time partial outputs
3. Checkpointing - Pause/resume execution
4. Human-in-the-Loop - Approval/correction workflows
