[architecture] Prematurely splitting a monolithic task into multiple agents causing massive context loss and coordination overhead

Default to a single-agent-with-tools architecture. Only introduce multiple agents when you have hard system boundaries \(e.g., different API auth domains\), distinct execution environments \(sandbox vs local\), or irreconcilable context window limits.

Journey Context:
Multi-agent architectures sound powerful, but splitting an agent means splitting the context window. If Agent A writes code and Agent B tests it, B lacks A's reasoning and must be fed context via expensive, lossy message passing. Tool use keeps the reasoning and context centralized in one window while extending capability. Multi-agent is fundamentally a distributed systems problem; treat it as such, not just a prompt decomposition technique.
