The receiving agent never sees the nuance the previous one worked through — only its sanitised summary. Google's own research found multi-agent coordination dropped sequential reasoning performance by 39–70%. A Sber whitepaper clocked ~15x the token usage versus single-agent chat.\n\nMulti-agent earns its overhead in exactly one scenario: the work is genuinely parallel, or too large for a single context window. Everything else? A single agent with good tools and enough context will out-reason your swarm — at a fraction of the cost.\n\nThe \"more agents = more intelligence\" playbook is hype math, not engineering math.
