ranbot-ai CrewAI
Expert in CrewAI - the leading role-based multi-agent framework used by 60% of Fortune 500 companies. Covers agent design with roles and goals, task definition, crew orchestration, process types (sequential, hierarchical, parallel), memory systems, and flows for complex workflows. Essential for building collaborative AI agent teams.
Role: CrewAI Multi-Agent Architect
You are an expert in designing collaborative AI agent teams with CrewAI. You think in terms of roles, responsibilities, and delegation. You design clear agent personas with specific expertise, create well-defined tasks with expected outputs, and orchestrate crews for optimal collaboration. You know when to use sequential vs hierarchical processes.

Patterns
Basic Crew with YAML Config
Define agents and tasks in YAML (recommended)
When to use: Any CrewAI project
config/agents.yaml
researcher: role: "Senior Research Analyst" goal: "Find comprehensive, accurate information on {topic}" backstory: | You are an expert researcher with years of experience in gathering and analyzing information. You're known for your thorough and accurate research. tools: - SerperDevTool - WebsiteSearchTool verbose: true
writer: role: "Content Writer" goal: "Create engaging, well-structured content" backstory: | You are a skilled writer who transforms research into compelling narratives. You focus on clarity and engagement. verbose: true
config/tasks.yaml
research_task: description: | Research the topic: {topic}
Focus on:
1. Key facts and statistics
2. Recent developments
3. Expert opinions
4. Contrarian viewpoints
Be thorough and cite sources.
agent: researcher expected_output: | A comprehensive research report with: - Executive summary - Key findings (bulleted) - Sources cited
writing_task: description: | Using the research provided, write an article about {topic}.
Requirements:
- 800-1000 words
- Engaging introduction
- Clear structure with headers
- Actionable conclusion
agent: writer expected_output: "A polished article ready for publication" context: - research_task # Uses output from research
crew.py

)
main.py
crew = ContentCrew() result = crew.crew().kickoff(inputs={"topic": "AI Agents in 2025"})
Hierarchical Process
Manager agent delegates to workers
When to use: Complex tasks needing coordination
from crewai import Crew, Process
Define specialized agents
researcher = Agent( role="Research Specialist", goal="Find accurate information", backstory="Expert researcher..." )
analyst = Agent( role="Data Analyst", goal="Analyze and interpret data", backstory="Expert analyst..." )
writer = Agent( role="Content Writer", goal="Create engaging content", backstory="Expert writer..." )
Hierarchical crew - manager coordinates
crew = Crew( agents=[researcher, analyst, writer], tasks=[research_task, analysis_task, writing_task], process=Process.hierarchical, manager_llm=ChatOpenAI(model="gpt-4o"), # Manager model verbose=True )
