[architecture] Assuming more agents equals better results

Start with one capable agent plus a library of tools/skills. Introduce additional agents only when there is a clear separation of concerns, security boundary, or failure domain that justifies the coordination cost.

Journey Context:
Over-decomposition is common: every subtask becomes its own agent, adding latency, serialization cost, and failure modes for no gain. A single agent calling deterministic tools is simpler, cheaper, and easier to debug. Multi-agent is the right call for isolation \(e.g., untrusted code execution, conflicting roles\) or genuinely independent workflows, not for every function call.
