[architecture] Starting with a multi-agent architecture before proving you need one

Build a single agent with a strong tool/skill library first; split into multiple agents only when roles, failure domains, or scaling requirements truly diverge.

Journey Context:
Multiple agents add coordination, latency, and debugging surface. Many teams split too early because it sounds clean, then spend most of their time on message protocols instead of task quality. A single agent with well-defined tools is easier to evaluate, cheaper to run, and simpler to debug. Multi-agent is the right call when different tasks need different models, different trust boundaries, or independent scaling.
