[architecture] What LLM routing pattern should I use as my agent system grows?

Start with a single agent loop and only add a router when the tool/agent set grows. Then use the manager pattern \(agents exposed as tools\) when you want one agent to own workflow execution and synthesize results, or the decentralized pattern \(handoffs between peer agents\) when specialized agents should own the conversation. Avoid complex multi-agent graphs until simple orchestration demonstrably fails.

Journey Context:
OpenAI's guide models multi-agent systems as graphs: in the manager pattern edges are tool calls; in the decentralized pattern edges are handoffs. The common mistake is jumping to multi-agent before a single agent with well-designed tools and prompt templates is exhausted. Single-agent loops keep evaluation and maintenance simple; manager patterns preserve unified control; handoffs work best for triage and domain specialization.
