Complex problems often benefit from multiple specialized agents rather than one general-purpose bot. The orchestration patterns: supervisor agents delegate to specialists, message-passing between agents, or hierarchical agents where one agent oversees others.
Design agent specializations: a researcher agent gathers information, an analyzer agent processes it, a writer agent creates output. Each has its own system prompt, tools, and focus. Coordination determines how they communicate—or how they compete to answer.
The simplest pattern: router agent receives requests, delegates to appropriate specialist. More complex: parallel execution where multiple agents work simultaneously, then their results are merged. Agent-to-agent messages enable sophisticated coordination.
