[architecture] When is a single agent with many tools better than multiple specialized agents?

Use one agent plus a rich tool library for simple or tightly coupled tasks; introduce specialists only when tools and prompts are domain-conflicting, the context window is exceeded, or subtasks must be owned by separate services.

Journey Context:
A single agent avoids routing overhead and keeps the full context in one prompt. Multi-agent adds latency and cost but reduces hallucinated tool selection and lets you version domains independently. The OpenAI Agents SDK recommends specialized agents over a generalist, but specialization should be driven by task heterogeneity and ownership boundaries, not by fashion.
