[architecture] Deciding between a single agent with a skill library versus multiple specialized agents

Default to a single agent with tools. Only introduce multiple agents when you need isolated context windows, distinct system prompts, or parallel execution.

Journey Context:
The common trap is assuming multiple agents are inherently more capable. In reality, agent handoffs introduce latency, token overhead for context serialization, and failure points. If tasks are tightly coupled and share the same context, a single agent with a well-defined tool suite is more reliable and cheaper. Multi-agent is only justified when the cognitive load or system instructions exceed a single prompt's capacity, or when tasks can run independently in parallel.
