What are the biggest challenges in multi-agent system development?

When building systems where multiple AI agents collaborate, I highlight three critical bottlenecks:Context Collisions and “Hallucinatory Resonance” : A situation where one agent generates a false premise, and the second agent builds upon it, amplifying the error exponentially.Orchestration and State Management : The difficulty of maintaining a coherent “shared memory” without over-inflating the context window or wasting tokens.

Infinite Loop Logic : The risk of agents entering a recursive cycle of clarifying questions instead of moving toward task execution.
