Agent Orchestration
Agent orchestration is the systematic coordination and management of multiple AI agents working together to achieve complex objectives. Rather than relying on a single monolithic AI system, orchestration leverages a distributed network of specialized agents, each designed for specific tasks, with an orchestration layer coordinating their interactions.
Core Concept
The orchestration layer acts as a “traffic manager” that:
- Decides which agent performs which task
- Determines execution order and sequencing
- Applies workflows, rate limits, and routing rules
- Prevents agent conflicts
- Maintains context and state across agents
- Balances load and prioritizes requests
Types of Orchestration Patterns
Parallel Orchestration (Concurrent Execution)
Multiple agents operate simultaneously on different aspects of the same problem, dramatically accelerating results by eliminating sequential bottlenecks.
Example: Loan application processing
- Agent 1: Verifies employment
- Agent 2: Checks credit history
- Agent 3: Assesses collateral value
- All execute concurrently, results converge for final decision
Benefits:
- Reduced processing time
- Resource efficiency
- Enhanced scalability
- Faster real-time response
Requirements:
- Robust conflict prevention when agents access shared data
- Independent subtasks
- Clear convergence points
Sequential Orchestration (Linear Execution)
Agents complete tasks in predefined order where one agent’s output becomes the next agent’s input. Like an assembly line, strictly deterministic.
Example: Report generation
- Data collection agent gathers information
- Analysis agent processes the data
- Reporting agent creates final document
Use cases:
- Tasks with strict ordering requirements
- Dependency-heavy workflows
- Step-by-step processes
Technical Implementation
LLM-Based Orchestration
Allow large language models to make intelligent decisions about task flow, routing, and prioritization based on context and goals.
Code-Based Orchestration
Program orchestration using primitives like Python’s asyncio.gather to explicitly manage concurrent agent execution.
Hybrid Approach
Combine intelligent LLM decision-making with explicit control structures for deterministic workflows.
Orchestration Architectures
While orchestration patterns describe how work flows between agents, orchestration architectures describe organizational relationships:
Centralized Orchestration
- Master agent directs all other agents
- Single point of control
- Easier to manage but potential bottleneck
Decentralized Orchestration
- Agents interact peer-to-peer
- Distributed decision-making
- More resilient, more complex
Hierarchical Orchestration
- Agents organized in tiered command structures
- Different levels of authority
- Balances control and flexibility
Key Components
Communication Protocols
Standardized protocols allow agents to:
- Share data and results
- Exchange progress updates
- Send requests and queries
- Maintain consistency
Context Awareness & Memory
The orchestration framework maintains:
- Shared context across agents
- Relevant parameters throughout workflows
- Historical decisions and outcomes
- State consistency
Workflow Management
- Task definition and routing
- Dependency resolution
- Error handling and retry logic
- Monitoring and observability
Advantages & Benefits
Problem-Solving
- Leverages combined strengths of multiple specialized agents
- Surpasses what single AI can achieve
- Enables more complex automation
Efficiency
- Distributes workloads among agents
- Maximizes computational resource utilization
- Eliminates sequential bottlenecks
Scalability
- Handles significantly more tasks in parallel
- Distributes load across multiple agents
- Gracefully scales with complexity
Robustness
- Fault isolation (failure in one agent doesn’t halt system)
- Redundancy through multiple agents
- Better error recovery
Practical Applications

Relationship to Compound Engineering
Compound Engineering applies orchestration principles to software development:
- Multiple agents (frontend, backend, testing, docs) work in parallel
- Human orchestrators handle architecture and design decisions
- Each iteration teaches the system, accelerating future work
Tools & Frameworks
Common platforms enabling agent orchestration:
- Claude Code (Anthropic)
- Anthropic API with custom orchestration
- LangChain/LangGraph for workflow definition

Best Practices
- Clear task decomposition: Break work into independent, well-defined subtasks
- Explicit interfaces: Define how agents communicate and share data
- Convergence points: Establish clear points where parallel work merges
- Monitoring: Implement comprehensive observability
- Error handling: Design graceful failure and recovery
- Documentation: Document agent roles, capabilities, and communication patterns
