[architecture] Building a multi-agent team when a single agent with a good tool library would suffice

Start with one agent plus a curated skill/tool library; introduce a second agent only when you have identified a conflict of responsibilities \(e.g., code generation vs. security review\) that a single prompt cannot resolve.

Journey Context:
Multi-agent is seductive but adds coordination, latency, and state-synchronization costs. Anthropic's research on effective agents emphasizes that the biggest gains come from better tools and retrieval, not from adding agents. Many problems labeled 'multi-agent' are really just 'one agent with many tools.' Add agents when roles need autonomy, oversight, or adversarial checks—not because it sounds more sophisticated. The wrong call produces handoff bugs for no benefit.
