[architecture] When to use multiple agents instead of one agent with many tools

Use a single agent with tools if the context window can hold the tool schemas and the tasks are highly sequential or coupled. Use multi-agent when context limits are hit, responsibilities are cleanly partitionable, or parallel execution is required.

Journey Context:
Adding agents adds coordination overhead \(handoffs, state sync, routing\). If one agent can do it, it is faster and less error-prone. Multi-agent shines when you need isolated context to avoid distraction, or when tasks can be parallelized. A common mistake is creating an agent for every micro-task, leading to a fragile Rube Goldberg machine where context passing fails.
