[architecture] Over-engineering a multi-agent system when a single agent with a skill library suffices

Default to a single-agent-plus-tools architecture. Only introduce multiple agents if there is a fundamental context window isolation requirement, conflicting system prompts, or distinct security boundaries.

Journey Context:
Multi-agent is a buzzword. Routing to different agents incurs latency, context loss, and coordination overhead. A single strong model with a well-defined tool library often outperforms a fragmented multi-agent system because it maintains full context. Multi-agent is only justified when system prompts actively conflict or context is too large.
