Simple DEV Blog Post Writer with LangGraph Multi Agents with Memory, AWS Bedrock Nova: Generator & Evaluator Pattern

Short summary

This tutorial demonstrates building a multi-agent blog post generator using LangGraph, AWS Bedrock Nova, and persistent memory. The generator-evaluator pattern separates content creation from review, catching errors through iterative refinement. Code includes keyword extraction, topic research, draft generation, and evaluation loops—a practical starting point for agentic content pipelines.

• •Multi-agent architecture with LangGraph: generator creates, evaluator provides feedback for refinement
• •Complete Python implementation with AWS Bedrock Nova, memory persistence, and DuckDuckGo research
• •Production-ready patterns for content generation pipelines with iterative quality improvement
