[architecture] Choosing multi-agent architecture when a single agent with tools suffices

Default to a single agent with a skill/tool library. Only introduce multiple agents if you need parallel execution, strictly isolated system prompts/personas, or to bypass context window limits.

Journey Context:
Engineers often map distinct tasks to distinct agents, but this introduces massive coordination overhead, state synchronization complexity, and context fragmentation. A single LLM with well-defined tools can switch between 'roles' seamlessly without the latency and error-prone handoffs of multi-agent systems. Multi-agent is justified only when tasks must run concurrently or when system prompts fundamentally conflict.
