[architecture] Deciding between a single agent with tools versus multiple specialized agents

Default to a single agent with a skill library; only introduce multiple agents when you need distinct system boundaries, isolated context windows, or strict permission separation.

Journey Context:
Multi-agent systems introduce massive coordination overhead, state synchronization bugs, and prompt fragmentation. A single agent with tools is deterministic, maintains a unified context, and avoids handoff failures. Multi-agent is only justified when context limits are hit or when agents represent different security principals \(e.g., a read-only DB agent vs. an admin agent\).
