Description

Hierarchical Multi-Agent Teams extend the Supervisor pattern by nesting multiple supervisors into a tree structure. A top-level supervisor delegates to mid-level supervisors, each of which manages their own team of specialized worker agents. This mirrors how large organizations structure teams with managers and sub-teams.

When to Use

  • Large-scale, multi-domain tasks requiring many specialized agents
  • When a single supervisor would be overloaded with too many workers
  • Projects requiring both research AND implementation teams
  • Enterprise workflows with clear team boundaries and responsibilities

Benefits

Benefit Description
Scalability Manage dozens of agents through hierarchical delegation
Team Autonomy Each sub-team operates independently within its domain
Reduced Complexity Each supervisor manages only a few direct reports
Composability Teams can be assembled from reusable sub-team modules
