[counterintuitive] Adding more agents to a system automatically improves problem-solving capability

Start with a single, well-prompted agent equipped with a robust toolset. Only introduce multi-agent architectures when you need strict role-based access controls, parallelized independent tasks, or isolated context windows to prevent context overload.

Journey Context:
Multi-agent systems introduce massive orchestration complexity: context synchronization overhead, cascading errors, infinite conversational loops, and multiplied token costs. A single agent with a strong system prompt and comprehensive tools often outperforms a chaotic multi-agent setup because it maintains a unified state and doesn't suffer from 'telephone game' degradation where context is lost between agent handoffs.
