[architecture] When to use multiple agents instead of a single agent with a skill library?

Use multi-agent only when tasks require isolated context boundaries or parallel execution; otherwise, prefer a single agent with tools to avoid coordination overhead and state synchronization costs.

Journey Context:
Beginners over-decompose tasks into multiple agents, leading to 'chatter' and state sync issues. A single LLM with well-defined tools shares memory natively. Multi-agent is right when agents need distinct system prompts or when sub-tasks can run concurrently without stepping on each other's context.
