[architecture] Over-engineering multiple agents when a single agent with tools suffices

Default to a single agent with a skill/tool library. Only introduce multiple agents if you need parallel execution, isolated context windows for divergent tasks, or distinct security/permission boundaries.

Journey Context:
Multi-agent systems introduce massive overhead in state synchronization, context passing, and handoff logic. LLMs natively excel at selecting the right tool for the job within a single context. Splitting agents prematurely leads to fragmented context and brittle orchestration. Multi-agent is the right call only when the context window overflows or when a strict permission boundary \(e.g., read-only vs admin\) must be enforced at the architectural level.
