Hierarchical
The Hierarchical, or Tree, Orchestration Pattern is a powerful approach to organizing multi-agent workflows, inspired by traditional organizational structures where work and information flow through a well-defined chain of command. This pattern creates a tree-structured arrangement of agents with clear levels of responsibility, specialization, and reporting relationships.
Key Characteristics#
The Hierarchical Pattern establishes distinct agent roles across three primary levels:
-
Executive Level (Top): An executive agent maintains strategic oversight of the entire task. This agent breaks complex problems into logical components, delegates to appropriate domain managers, provides overall direction, and ultimately synthesizes the final output.
-
Manager Level (Middle): Manager agents have responsibility for specific domains. Each manager breaks down their assigned component into specialized subtasks, delegates to appropriate specialists, monitors progress, provides guidance, and aggregates results before reporting back to the executive.
-
Specialist Level (Bottom): Specialist agents possess deep expertise in narrow areas. They focus exclusively on well-defined, discrete tasks without needing to understand the entire problem context. These agents do the detailed work and report their findings back to their respective managers.
Information Flow#
The strength of this pattern comes from its structured information flow:
-
Downstream Flow: Tasks, requirements, and context flow from the executive to managers to specialists, becoming more specialized and focused at each level.
-
Upstream Flow: Results, findings, and completed work flow from specialists to managers to the executive, being aggregated and refined at each level.
Implementation#
In our implementation using AG2's Group Chat, we've created:
-
A clear hierarchy with one executive agent, three manager agents (Renewable, Storage, Alternative), and five specialist agents organized under their respective managers.
-
Explicit handoffs designed around the hierarchy:
- Context-based transitions using
OnContextConditionfor deterministic, non-LLM routing - LLM-based fallbacks using
OnConditionfor more complex decisions -
Explicit
AfterWorkdesignations to ensure agents always report back to their supervisors -
Shared context variables to track progress at different levels, allowing for:
- Deterministic routing based on task completion status
- Storage of research content provided by specialists
-
Aggregation of report sections compiled by managers
-
A complete workflow that follows organizational principles:
- The executive delegates tasks to managers
- Managers delegate to their respective specialists
- Specialists conduct research and report back to managers
- Managers synthesize findings into sections and report to the executive
- The executive compiles the final report and presents it to the user
This pattern is particularly effective for complex, multi-faceted tasks where different aspects require specialized knowledge, and where the final output needs to synthesize diverse findings into a cohesive whole. The implementation demonstrates how automated agents can effectively mirror human organizational structures to tackle complex problems through division of labor and hierarchical information flow.
The hierarchical structure enables efficient cognitive division of labor - higher-level agents handle integration and context, while lower-level agents focus on specific details, resulting in a comprehensive final output that leverages the strengths of each level in the hierarchy.

Tip
In this code example we use OpenAI's GPT-4o mini.
We also set the LLM parameter parallel_tool_calls to False so that our agents don't recommend more than one tool call at a time. This parameter may not be available with all model providers.

{"research_content":"1. Current State of Wind Technology:\nThe wind energy sector has seen substantial growth with advancements in both onshore and offshore wind technologies. \n- Onshore wind farms remain the dominant form of wind energy generation, due to lower costs and established infrastructure. However, the trend is shifting towards larger, more efficient turbines and hybrid systems that increase energy capture.\n- Offshore wind technology is rapidly advancing with larger turbines (up to 15 MW) and floating wind farms expanding the potential for energy generation in deeper waters. As of 2023, the global installed offshore wind capacity exceeds 50 GW.\n\n2. Efficiency Rates of Modern Wind Turbines:\nModern onshore turbines typically have efficiency rates (capacity factors) around 35-45%, while offshore turbines can achieve 45-55% efficiency under optimal conditions. The technological advancements in turbines, such as larger rotor diameters and improved drivetrain systems, contribute to these efficiency gains.\n\n3. Cost Comparison with Fossil Fuels:\nThe cost of wind energy has significantly decreased, making it competitive with fossil fuels.
