Multi-Agent Systems
Team of AI agents
The Problem: One AI trying to do everything is like one person trying to build a house alone — architect, plumber, electrician, all at once. It's possible but inefficient and error-prone.
The Solution: A Team of Specialists
Instead of one super-agent, use multiple specialized agents that work together. Each agent is an expert in its area, and an orchestrator coordinates them to solve complex problems. Individual agents often follow the ReAct pattern, while planning keeps the overall task on track.
Think of it like a startup team:
- 1. CEO Agent: Coordinates work, makes high-level decisions
- 2. Researcher Agent: Finds information, analyzes data
- 3. Coder Agent: Writes and reviews code
- 4. Writer Agent: Creates documentation, reports
- 5. Critic Agent: Reviews work, finds issues
They communicate, delegate tasks, and build on each other's work!
Why Multiple Agents?
- Specialization: Each agent can have focused skills and tools
- Parallel work: Multiple agents can work simultaneously
- Checks & balances: One agent can review another's work
- Simpler prompts: Easier to instruct a specialist than a generalist
Fun Fact: Research shows that having AI agents "debate" each other often produces better answers than a single agent! One agent proposes a solution, another critiques it, and through this back-and-forth, they reach better conclusions.

Write a short marketing copy for a new meditation app.
Discover peace with our new meditation app! Relax, reduce stress, and find harmony. Download now!
[Writer Agent, iteration 1] "Discover a world of silence. Our app helps you meditate anywhere. Begin your journey to harmony."
[Critic Agent]
- Too generic, no uniqueness
- No specific benefits (how many minutes? what techniques?)
- No emotional hook
- Recommendation: add specifics and social proof
[Writer Agent, iteration 2] "5 minutes of silence can change your whole day. Join 50,000+ people who start their morning with mindful breathing. Personalized programs, sleep timer, meditations for anxious moments — all in one app. First 7 days free."
A multi-agent system enables iterative improvement. The Critic catches what the Writer missed, and the second pass produces significantly better copy.
