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

Default to a single-agent architecture with well-defined tools. Only introduce multiple agents if there is a strict need for isolated context windows, parallel execution, or fundamentally conflicting system prompts.

Journey Context:
The hype around multi-agent systems leads developers to split tasks prematurely. This introduces massive overhead: context handoff latency, state synchronization bugs, and routing failures. A single LLM with a large context and a suite of tools coordinates internally far better than a fragile external orchestration layer can.
