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

Default to a single agent with tools; only split into multiple agents when you need distinct system prompts, isolated context windows, or separate security boundaries.

Journey Context:
Multi-agent architectures are appealing but introduce massive overhead in context handoff, state synchronization, and routing logic. Every handoff risks dropping critical context. A single agent maintains a unified mental model and avoids the 'telephone game' of degraded instructions. The tradeoff is that a single agent's prompt can become bloated, leading to confused tool selection, but prompt bloat is usually cheaper to debug than distributed state corruption.
