[architecture] Prematurely splitting a monolithic agent into multiple coordinating agents

Start with a single agent plus a skill/tool library. Only split into multi-agent if there are conflicting system prompts, distinct security boundaries, or context window limits that cannot be solved by retrieval-augmented generation \(RAG\).

Journey Context:
Multi-agent is architecturally seductive but introduces massive coordination overhead \(state sync, messaging parsing, routing failures\). A single agent with well-defined tools maintains a unified context window and coherent persona. The tradeoff is that a single agent's context can get cluttered, but RAG or summarization mitigates this cheaper than managing inter-agent handoffs.
