Single-Agent vs Multi-Agent Systems: The Hidden Cost of the Coordination Tax

The industry is obsessed with multi-agent swarms, but in enterprise production, every additional agent introduces latency, token overhead, and compounding failure probabilities. We break down the coordination tax and when single monolithic agents outperform swarms.

The Math of the Coordination Tax

Compound reliability curves, message serialization latency, and routing overhead.
