Report #101144

[architecture] A team of agents is slower and more expensive than a single agent with tools for a task one agent could handle

Default to one agent plus deterministic tool/skill library; introduce additional agents only for independent, long-running, or trust-separated concerns.

Journey Context:
Frameworks make multi-agent look like the right default, but each agent adds latency, cost, and failure modes. Anthropic's production experience shows most workflows are better as prompt chaining, routing, or a single augmented LLM. Split into multiple agents when lanes are truly independent or when separation of privileges matters. The wrong path is splitting by role because it mirrors an org chart.
