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

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

Journey Context:
Multi-agent systems introduce latency, state synchronization overhead, and error propagation. A single agent maintains a unified context window, avoiding context loss during handoffs. Developers often create multiple agents for logical modularity, but LLMs handle modularity via tools just as well without the overhead of inter-agent communication.
