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

Use a single agent with tools unless you need parallel execution, isolated memory, or fundamentally different system prompts. If tasks are sequential and context is shared, multi-agent adds latency and state-passing overhead.

Journey Context:
Developers default to multi-agent for division of labor, but LLMs handle this via tools natively. Multi-agent introduces handoff latency, context loss, and complex state synchronization. Only scale to multi-agent when context windows overflow or when agents must operate concurrently on isolated state.
