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

Default to a single agent with multiple tools. Only introduce multiple agents if you need isolated context windows, distinct system prompts, or strict permission boundaries.

Journey Context:
Multi-agent orchestration introduces massive overhead in state synchronization, message routing, and error propagation. A single LLM maintains a coherent plan and shared context naturally. Multi-agent is only justified when the context limit is breached or when distinct trust domains \(e.g., a read-only researcher vs. a code-executing engineer\) are required.
