CrewAI Examples
CrewAI is a framework for orchestrating role-playing, autonomous AI agents:
# Example: Email Auto Responder (Communication)
# Repository: crewAI-examples/flows/email_auto_responder_flow
from crewai import Agent, Task, Crew
# Define agents
email_classifier = Agent(
role="Email Classifier",
goal="Classify incoming emails by priority and category",
backstory="Expert at email triage and organization"
)
response_writer = Agent(
role="Response Writer",
goal="Draft appropriate email responses",
backstory="Professional communication specialist"
)
# Define tasks
classify_task = Task(
description="Classify the email: {email_content}",
agent=email_classifier
)
respond_task = Task(
description="Write response for classified email",
agent=response_writer
)
# Create crew
crew = Crew(
agents=[email_classifier, response_writer],
tasks=[classify_task, respond_task]
)
# Execute
result = crew.kickoff(inputs={"email_content": "..."})
CrewAI Use Cases in Catalog:
- Email Auto Responder Flow (Communication)
- Meeting Assistant Flow (Productivity)
- Lead Score Flow (Sales)
- Marketing Strategy Generator (Marketing)
- Job Posting Generator (Recruitment)
- Recruitment Workflow (HR)
AutoGen Examples
AutoGen enables development of LLM applications using multiple agents:
# Example: Multi-agent collaboration
# Common pattern in AutoGen projects
import autogen
config_list = autogen.config_list_from_json(
"OAI_CONFIG_LIST",
filter_dict={"model": ["gpt-4"]}
)
# Create assistant agent
assistant = autogen.AssistantAgent(
name="assistant",
llm_config={"config_list": config_list}
)
# Create user proxy agent
user_proxy = autogen.UserProxyAgent(
name="user_proxy",
human_input_mode="NEVER",
code_execution_config={"work_dir": "coding"}
)
# Initiate conversation
user_proxy.initiate_chat(
assistant,
message="Analyze this dataset and provide insights"
)
LangGraph Examples
LangGraph is used for building stateful, multi-actor applications with LLMs:
# Example: Customer Support Agent
# Repository: GenAI_Agents/customer_support_agent_langgraph.ipynb
from langgraph.graph import StateGraph, END
from langchain_core.messages import HumanMessage
# Define state
class AgentState(TypedDict):
messages: list[HumanMessage]
next_step: str
# Define nodes
def classify_query(state):
"""Classify customer query"""
# Classification logic
return {"next_step": "technical" if is_technical else "general"}
def technical_support(state):
"""Handle technical queries"""
# Technical support logic
return {"messages": state["messages"] + [response]}
def general_support(state):
"""Handle general queries"""
# General support logic
return {"messages": state["messages"] + [response]}
# Build graph
workflow = StateGraph(AgentState)
workflow.add_node("classify", classify_query)
workflow.add_node("technical", technical_support)
workflow.add_node("general", general_support)
workflow.set_entry_point("classify")
workflow.add_conditional_edges(
"classify",
lambda x: x["next_step"],
{"technical": "technical", "general": "general"}
)
workflow.add_edge("technical", END)
workflow.add_edge("general", END)
app = workflow.compile()
# Run
result = app.invoke({
"messages": [HumanMessage(content="My app crashed")],
"next_step": ""
})
Common Patterns
Pattern 1: Finding Relevant Use Cases
# Search the catalog programmatically
import requests
import re
def find_use_cases_by_industry(industry: str):
"""Find AI agent use cases for a specific industry"""
url = "https://raw.githubusercontent.com/ashishpatel26/500-AI-Agents-Projects/main/README.md"
response = requests.get(url)
# Parse markdown table
lines = response.text.split('\n')
use_cases = []
for line in lines:
if industry.lower() in line.lower() and '|' in line:
parts = [p.strip() for p in line.split('|')]
if len(parts) > 4:
use_cases.append({
'name': parts[1],
'industry': parts[2],
'description': parts[3],
'github_link': extract_github_link(parts[4])
})
return use_cases
def extract_github_link(markdown_link: str) -> str:
"""Extract GitHub URL from markdown link"""
match = re.search(r'https://github\.com/[^\)]+', markdown_link)
return match.group(0) if match else None
# Usage
healthcare_agents = find_use_cases_by_industry("Healthcare")
for agent in healthcare_agents:
print(f"{agent['name']}: {agent['description']}")
print(f"GitHub: {agent['github_link']}\n")
Pattern 2: Exploring Framework Examples
def get_framework_examples(framework: str):
"""Get examples for a specific framework (CrewAI, AutoGen, LangGraph)"""
url = "https://raw.githubusercontent.com/ashishpatel26/500-AI-Agents-Projects/main/README.md"
response = requests.get(url)
# Find framework section
content = response.text
framework_section = re.search(
f'### \\*\\*Framework Name\\*\\*: \\*\\*{framework}\\*\\*(.*?)(?=###|$)',
content,
re.DOTALL | re.IGNORECASE
)
if framework_section:
section_text = framework_section.group(1)
# Parse table rows
examples = []
for line in section_text.split('\n'):
if '|' in line and 'Use Case' not in line and '---' not in line:
parts = [p.strip() for p in line.split('|')]
if len(parts) > 3:
examples.append({
'use_case': parts[1],
'industry': parts[2],
'description': parts[3]
})
return examples
return []
# Usage
crewai_examples = get_framework_examples("CrewAI")
print(f"Found {len(crewai_examples)} CrewAI examples")
Pattern 3: Building Custom Agent from Catalog
# Example: Implementing a Healthcare AI Agent based on catalog
from langchain.agents import initialize_agent, Tool
from langchain.llms import OpenAI
from langchain.memory import ConversationBufferMemory
import os
class HealthInsightsAgent:
"""
Based on: HIA (Health Insights Agent)
Repository: github.com/harshhh28/hia
"""
def __init__(self):
self.llm = OpenAI(
temperature=0,
api_key=os.getenv("OPENAI_API_KEY")
)
self.memory = ConversationBufferMemory(
memory_key="chat_history",
return_messages=True
)
self.tools = self._create_tools()
self.agent = initialize_agent(
self.tools,
self.llm,
agent="conversational-react-description",
memory=self.memory
)
def _create_tools(self):
return [
Tool(
name="Analyze Medical Report",
func=self.analyze_report,
description="Analyzes medical reports and extracts key insights"
),
Tool(
name="Health Recommendations",
func=self.get_recommendations,
description="Provides health recommendations based on analysis"
)
]
def analyze_report(self, report_text: str) -> str:
"""Analyze medical report"""
# Implementation based on HIA project
prompt = f"Analyze this medical report and extract key findings:\n{report_text}"
return self.llm(prompt)
def get_recommendations(self, findings: str) -> str:
"""Generate health recommendations"""
prompt = f"Based on these findings, provide health recommendations:\n{findings}"
return self.llm(prompt)
def chat(self, message: str) -> str:
"""Main chat interface"""
return self.agent.run(message)
# Usage
agent = HealthInsightsAgent()
response = agent.chat("Analyze my recent blood test results")
print(response)
Pattern 4: Multi-Industry Agent System
# Example: Creating a multi-purpose agent that handles different industries
from typing import Dict, List
import json
class IndustryAgentRouter:
"""
Routes queries to appropriate industry-specific agents
Based on patterns from the 500 AI Agents catalog
"""
def __init__(self):
self.industry_keywords = {
'healthcare': ['medical', 'health', 'diagnosis', 'patient', 'treatment'],
'finance': ['trading', 'stock', 'investment', 'market', 'portfolio'],
'education': ['learn', 'study', 'course', 'tutor', 'exam'],
'retail': ['product', 'shop', 'purchase', 'recommendation', 'inventory'],
'customer_service': ['support', 'help', 'ticket', 'complaint', 'query']
}
self.agents = self._initialize_agents()
def _initialize_agents(self) -> Dict:
"""Initialize industry-specific agents"""
return {
'healthcare': HealthcareAgent(),
'finance': FinanceAgent(),
'education': EducationAgent(),
'retail': RetailAgent(),
'customer_service': CustomerServiceAgent()
}
def classify_query(self, query: str) -> str:
"""Classify query to determine industry"""
query_lower = query.lower()
scores = {}
for industry, keywords in self.industry_keywords.items():
score = sum(1 for keyword in keywords if keyword in query_lower)
scores[industry] = score
return max(scores, key=scores.get) if max(scores.values()) > 0 else 'general'
def route_query(self, query: str) -> str:
"""Route query to appropriate agent"""
industry = self.classify_query(query)
if industry in self.agents:
return self.agents[industry].process(query)
else:
return "I'm not sure which department can help with that. Can you be more specific?"
# Usage
router = IndustryAgentRouter()
response = router.route_query("I need help analyzing my stock portfolio")
Environment Variables
When implementing agents from the catalog, common environment variables needed:
# LLM API Keys
export OPENAI_API_KEY=your_openai_key
export ANTHROPIC_API_KEY=your_anthropic_key
export GOOGLE_API_KEY=your_google_key
# Framework-specific
export CREWAI_API_KEY=your_crewai_key
export LANGCHAIN_API_KEY=your_langchain_key
# Database (if needed)
export DATABASE_URL=your_database_url
# Vector stores
export PINECONE_API_KEY=your_pinecone_key
export WEAVIATE_URL=your_weaviate_url
Troubleshooting
Issue: Repository Links Not Working
Some projects may have been moved or archived. Check the original repository:
import requests
def verify_github_link(github_url: str) -> bool:
"""Verify if GitHub repository still exists"""
response = requests.get(github_url)
return response.status_code == 200
# Usage
url = "https://github.com/harshhh28/hia"
if verify_github_link(url):
print("Repository is accessible")
else:
print("Repository may have moved or been deleted")
Issue: Framework Version Compatibility
Different examples may use different framework versions:
# Check requirements from a specific example
curl -s https://raw.githubusercontent.com/crewAIInc/crewAI-examples/main/requirements.txt
# Install specific version
pip install crewai==0.1.0 # Use version from example
Issue: Finding Similar Use Cases
If you can't find an exact match, search for similar patterns:
from difflib import SequenceMatcher
def find_similar_use_cases(target_description: str, all_use_cases: List[Dict], threshold=0.6):
"""Find use cases similar to target description"""
similar = []
for use_case in all_use_cases:
similarity = SequenceMatcher(
None,
target_description.lower(),
use_case['description'].lower()
).ratio()
if similarity >= threshold:
similar.append({
'use_case': use_case,
'similarity': similarity
})
return sorted(similar, key=lambda x: x['similarity'], reverse=True)
Best Practices
Start with Framework Examples: Begin with the framework-specific section (CrewAI, AutoGen, LangGraph) to understand implementation patterns
Check Repository Activity: Before implementing, verify the GitHub repository is actively maintained
Adapt to Your Needs: Use catalog examples as starting points, not complete solutions
Combine Use Cases: Many real-world applications combine multiple agent types (e.g., customer service + recommendation)
Environment Configuration: Always use environment variables for API keys and sensitive configuration
Version Control: Pin framework versions to match the examples for reproducibility
