Sub-Agents

• used in Multi-Agent workflows

Patterns

Fan-Out/Fan-In

• Spawn multiple sub-agents in parallel for independent tasks
• aggregate results of all sub-agents
• Use case
  • Evaluate 5 models on the same benchmark

Pipeline

• Chain sub-agents where output of one agent becomes input of another
• Use case
  • Data Processing: extract → clean → analyze → report

Supervisor

• aka Hierarchical
• Parent agent directs to multiple specialized sub-agents
• Use case
  • Product launch report needs sales, engineering, and marketing data

Swarm

• aka Collaborative
• Multiple subagents work on the same problem, comparing approaches and converging on best solution
• Use case
  • Design review with architect, security, and performance subagents

Invoking Sub-Agents

• You can ask directly in the prompt to launch multiple subagents
