[architecture] Prematurely decomposing a system into multiple agents when a single agent with tools suffices

Default to a single agent with a robust skill/tool library. Only introduce multiple agents if there is a strict need for isolated context windows, divergent system prompts, or parallel execution.

Journey Context:
Multi-agent architectures introduce massive overhead: state synchronization, message parsing failures, and orchestration complexity. A single LLM with a well-defined tool interface is often more reliable and cheaper for tasks that fit within a single context window. Multi-agent should be a scaling strategy for cognitive load, not a default starting architecture.
