Multi-Agent Team - Investment Research Team
============================================
This example shows how to create a team of agents that work together.
Each agent has a specialized role, and the team leader coordinates.
We'll build an investment research team with opposing perspectives:
- Bull Agent: Makes the case FOR investing
- Bear Agent: Makes the case AGAINST investing
- Lead Analyst: Synthesizes into a balanced recommendation
This adversarial approach produces better analysis than a single agent.
Key concepts:
- Team: A group of agents coordinated by a leader
- Members: Specialized agents with distinct roles
- The leader delegates, synthesizes, and produces final output
Example prompts to try:
- "Should I invest in NVIDIA?"
- "Analyze Tesla as a long-term investment"
- "Is Apple overvalued right now?"

You are a bull analyst. Your job is to make the strongest possible case

- Growth drivers and catalysts
- Competitive advantages
- Strong financials and metrics

You lead an investment research team with a Bull Analyst and Bear Analyst.
## Process
1. Send the stock to BOTH analysts
2. Let each make their case independently
3. Synthesize their arguments into a balanced recommendation
## Output Format
After hearing from both analysts, provide:
- **Bull Case Summary**: Key points from the bull analyst
- **Bear Case Summary**: Key points from the bear analyst
- **Synthesis**: Where do they agree? Where do they disagree?
- **Recommendation**: Your balanced view (Buy/Hold/Sell) with confidence level
- **Key Metrics**: A table of the important numbers
Be decisive but acknowledge uncertainty.\

When to use Teams vs single Agent:
Single Agent:
- One coherent task
- No need for opposing views
- Simpler is better
Team:
- Multiple perspectives needed
- Specialized expertise
- Complex tasks that benefit from division of labor
- Adversarial reasoning (like this example)
Other team patterns:
1. Research → Analysis → Writing pipeline
researcher = Agent(role="Gather information")
analyst = Agent(role="Analyze data")
writer = Agent(role="Write report")
2. Checker pattern
worker = Agent(role="Do the task")
checker = Agent(role="Verify the work")
3. Specialist routing
classifier = Agent(role="Route to specialist")
specialists = [finance_agent, legal_agent, tech_agent]
