[architecture] Over-decomposing tasks into multiple agents when a single agent with a tool library suffices

Default to a single agent with a diverse skill/tool library. Only introduce multiple agents when you need isolated context windows, parallel execution, or fundamentally different system prompts/personas.

Journey Context:
Multi-agent systems introduce severe coordination overhead, state synchronization issues, and context loss between handoffs. A single agent maintains the full context in one window, avoiding the 'telephone game' degradation. The tradeoff is context window limits; if the agent's instructions and tool outputs exceed the window, you must split. But splitting prematurely is the most common architectural failure.
