[architecture] When to use multiple agents vs a single agent with tools

Default to a single agent with a skill/tool library; only adopt a multi-agent architecture when you need parallel execution, divergent system prompts, or strict isolation of context/memory.

Journey Context:
Multi-agent systems introduce massive overhead in the form of handoffs, state synchronization, and context loss. A single agent with a rich tool library maintains a unified context window, avoiding the 'telephone game' of agent-to-agent communication. Multi-agent is only justified when the system prompts logically conflict \(e.g., a strict code reviewer vs. a creative coder\) or when tasks must run concurrently.
