[architecture] Running agents as conversational peers when one should be a tool invoked by the other

When a primary agent needs a specific capability from another agent, wrap the secondary agent as a tool \(function\) that the primary calls and gets a structured result from. Use peer conversations only when both agents need independent conversation context and user interaction.

Journey Context:
There are two composition patterns: \(1\) primary agent calls secondary agent as a tool, receiving a structured result; \(2\) two peer agents converse as equals with separate conversation histories. The tool pattern is simpler, more predictable, and keeps the primary agent in control. The peer pattern allows richer back-and-forth but loses the calling agent's context and introduces coordination complexity. OpenAI Swarm's design favors the tool pattern conceptually: agents hand off control entirely via function calls. The key insight is that 'agent as tool' is almost always the right default because it preserves a single conversation context, avoids context-switching overhead, and makes the control flow explicit. Peer mode is justified only when each agent genuinely needs its own conversation history — e.g., a user-facing agent and a separate long-running background research agent.
