[architecture] When to use multiple agents versus a single agent with tools

Default to a single agent with a skill library \(tools\); only introduce multiple agents if you need distinct system prompts, isolated long-term memory, or different underlying foundation models.

Journey Context:
Multi-agent systems introduce orchestration overhead, context-passing loss, and latency. A single agent maintains a unified context window, avoiding the 'telephone game' where context degrades across handoffs. Multi-agent is only justified when isolation of instructions or state is a hard requirement, not just to conceptually separate tasks.
