Designing an Effective Multi-Agent System: a Hierarchical Two-Pizza Approach
Description:
The creator of Aster Agents shares insights on designing effective multi-agent systems using proven organizational principles.
Synopsis:
This articles explores how to:
- Structure AI teams using human organizational principles
- Implement hierarchical manager-worker agent relationships
- Optimize agent team size and responsibilities
- Build production-ready multi-agent systems
Context
As multi-agent systems become more complex, developers are finding that human organizational principles apply effectively to AI teams.
The article introduces the “Two-Pizza Rule” (teams small enough to feed with two pizzas) and hierarchical management structure for AI agents.
This approach addresses common failure modes in current multi-agent implementations.
Key Implementation Patterns
The article demonstrates three key patterns:
- Hierarchical Management
- Manager agent owns outcomes
- Worker agents handle specialized tasks
- Dynamic task delegation
- Team Size Optimization
- Maximum 7 worker agents
- Single-threaded manager
- Clear individual ownership
- Specialized agent roles
- Framework Selection
- Language-specific approaches
- Minimal external dependencies
- Production considerations
- Scalability requirements
These patterns suggest important strategic implications for teams building multi-agent systems.
Strategic Implications
For technical leaders, this suggests several key implications:
- Organization Design
- Clear agent responsibilities
- Measurable outcomes
- Quality control mechanisms
- Team size limits
- System Architecture
- Token window management
- Tool access control
- Framework independence
- Production readiness
- Development Approach
- Focused agent specialization
- Clear success metrics
- Incentive alignment
- Framework flexibility
To translate these implications into practice, teams need a clear implementation framework.
Implementation Framework
For teams building multi-agent systems:
- Manager Setup
- Define clear objectives
- Implement delegation logic
- Establish quality metrics
- Configure coordination mechanisms
- Worker Configuration
- Limit tool access (≤10 tools)
- Restrict task scope
- Define success criteria
- Implement reporting
- System Integration
- Select appropriate framework
- Manage dependencies
- Handle persistence
- Enable monitoring
This implementation framework leads to several key development considerations.
Development Strategy
Key development considerations include:
- Framework Selection
- Python: OpenAI/Anthropic SDK + Postgres
- JavaScript: Vercel AI SDK
- Production requirements
- Scaling considerations
- Agent Design
- Clear individual objectives
- Limited tool access
- Specialized capabilities
- Quality metrics
- System Management
- Token window optimization
- Error handling
- Persistence strategy
- Monitoring approach
While these technical considerations are crucial, we should considering the broader industry impact.
Personal Notes
The parallel between human organizational principles and AI agent systems is interesting to consider.
Just as effective human teams need clear leadership and specialized roles, AI agent teams benefit from similar structure.
Looking Forward: Multi-Agent Systems
These systems will likely evolve to include:
- Better orchestration tools
- Improved specialization mechanisms
- Enhanced quality control
- More sophisticated incentive systems
- Standardized organizational patterns
Conclusion
This structured approach to multi-agent system design could significantly improve reliability and effectiveness while reducing complexity.
