CrewAI Flows Examples

This directory contains examples demonstrating the CrewAI Flows pattern - a powerful orchestration framework for managing complex, multi-crew workflows with state management.

What are CrewAI Flows?

CrewAI Flows allow you to:

  • Orchestrate multiple crews in sequence or parallel
  • Manage state across different execution steps
  • Implement conditional logic and routing
  • Create human-in-the-loop workflows
  • Build complex automation pipelines

Examples in this Directory

1. Content Creator Flow

Multi-crew content generation system that:

  • Routes requests to specialized crews (Blog, LinkedIn, Research)
  • Generates professional content across different formats
  • Uses advanced orchestration with dynamic routing
  • Demonstrates complex multi-agent workflows

2. Email Auto Responder Flow

Automated email monitoring and response generation system that:

  • Monitors Gmail inbox at regular intervals
  • Filters and categorizes incoming emails
  • Generates appropriate draft responses
  • Maintains state of processed emails

3. Lead Score Flow

Lead qualification and outreach automation that:

  • Processes leads from CSV files
  • Scores and ranks leads based on criteria
  • Implements human review for top candidates
  • Generates personalized outreach emails

4. Meeting Assistant Flow

Meeting productivity automation that:

  • Processes meeting transcripts and notes
  • Extracts action items and decisions
  • Creates tasks in Trello
  • Sends notifications via Slack

5. Self Evaluation Loop Flow

Iterative content improvement system that:

  • Generates content (e.g., social media posts)
  • Self-evaluates against criteria
  • Automatically refines based on feedback
  • Implements retry logic with limits

6. Write a Book with Flows

Book creation automation that:

  • Generates book outlines
  • Writes chapters in parallel
  • Maintains consistency across sections
  • Compiles final manuscript

Common Flow Patterns

Sequential Execution

# Execute crews one after another
flow = Flow()
flow.add_crew(crew1)
flow.add_crew(crew2)

Parallel Execution

# Execute multiple crews simultaneously
await flow.run_parallel([crew1, crew2, crew3])

Conditional Routing

# Route based on previous results
@flow.router
def route_based_on_result(state):
    if state.score > 0.8:
        return "high_quality_path"
    return "needs_improvement_path"

Human-in-the-Loop

# Pause for human input
human_feedback = flow.wait_for_input("Review these results")

Getting Started
