[architecture] Over-engineering a multi-agent swarm for tasks a single agent with a tool library can handle

Default to a single-agent-plus-skills architecture. Only introduce multiple agents when you need conflicting system prompts, distinct model classes, or strict security boundaries.

Journey Context:
Multi-agent systems are seductive but introduce massive coordination overhead, state synchronization latency, and error propagation. A single frontier model with a well-defined set of tools often outperforms a swarm of smaller agents because it maintains unified context. Multi-agent is justified when agent personas conflict \(e.g., a strict reviewer vs. a creative writer\) or when routing to cheaper/specialized models, not just for 'doing more things'.
