A comprehensive collection of hands-on code examples and implementations for mastering advanced CrewAI concepts. This repository contains practical demonstrations and production-ready patterns from the CrewAI Lightning Lessons Series by Carmelo Iaria.
The CrewAI Lightning Lessons Series focuses on non-obvious, enterprise-grade concepts that separate professional implementations from hobbyist projects. Each lesson provides immediate actionable insights you can implement right away, backed by real-world case studies and advanced techniques.
Focus: Strategic decision-making between Flows and Crews for different automation scenarios
Key Topics:
- Flow architecture with
@start(),@listen(),@router()decorators - State management with structured vs. unstructured approaches
- Hybrid implementations combining Flows and Crews
