Common Agent Architecture Patterns
- Single agent: one controller, one set of tools, one goal. Simple and easy to debug. Best for focused tasks.
- Planner and executor: one agent creates a plan. A second agent executes each step. Separates planning from execution for complex goals.
- Multi-agent pipeline: each agent hands its output to the next agent in sequence. Good for multi-stage workflows.
- Supervisor and workers: a supervisor agent coordinates multiple worker agents. Workers report results to the supervisor.
- Hierarchical: agents are arranged in a tree. High-level agents delegate to lower-level specialists. Best for very complex goals.
- Reactive: agents respond to events or triggers rather than working toward a fixed goal. Good for monitoring and alerting.
