[architecture] Choosing multi-agent architecture when single agent with tools suffices

Default to a single agent with a tool/skill library; only introduce multiple agents if you require parallel execution, strict context isolation, or fundamentally different system personas.

Journey Context:
Developers often over-engineer by assigning every task to a separate agent, assuming it increases intelligence. In reality, multi-agent systems introduce massive coordination overhead, state synchronization bugs, and message-parsing failures \(the 'telephone game'\). A single LLM with a well-defined set of tools shares context natively and avoids inter-agent hallucination. Multi-agent is only justified when context windows overflow or when security and isolation boundaries demand distinct entities.
