[architecture] When should I use multiple agents instead of a single agent with a tool library?

Default to a single agent with a tool library. Only introduce multiple agents if you need isolated context windows, distinct system prompts, or true parallel execution of independent subtasks.

Journey Context:
Multi-agent systems are often over-engineered. A single agent maintains a unified, coherent context, whereas inter-agent communication is lossy, expensive, and requires complex serialization. Multi-agent is justified when a single context window cannot hold the required instructions/state, or when distinct, conflicting personas \(e.g., coder vs reviewer\) are needed.
