[architecture] Choosing between a single agent with a skill library vs multiple specialized agents

Use a single agent with a rich tool/skill library unless you need parallel execution, strict persona/prompt boundaries, or isolated memory. Multi-agent adds exponential coordination overhead.

Journey Context:
Beginners default to multi-agent for complex tasks, thinking 'divide and conquer'. But LLM context is usually large enough for one agent with many tools. Multi-agent introduces state sync issues, routing failures, and duplicated work. Only split agents when context limits are hit, or when strict role separation \(e.g., coder vs. reviewer\) prevents prompt interference and tool collision.
