[architecture] Prematurely splitting a monolithic agent into multiple agents, causing coordination overhead

Start with a single agent equipped with a well-organized skill/tool library. Only split into multiple agents if the system faces distinct context window limits, requires fundamentally different system prompts/personas, or needs isolated execution loops.

Journey Context:
'Multi-agent' is a buzzword. Splitting an agent into Agent A and Agent B means paying for context passing, handling handoff failures, and managing state synchronization. If Agent A and Agent B share the same persona and just call different tools, they should be one agent. Multi-agent is justified only when the system prompts diverge so heavily that they pollute each other's instruction space, or when tasks require parallel, isolated execution loops.
