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

Use a single agent with tools unless you need divergent system prompts, isolated context windows, or parallel execution of distinct cognitive tasks.

Journey Context:
Multi-agent introduces coordination overhead, state sync issues, and routing failures. A single agent maintains a unified context and avoids handoff errors. Multi-agent is only justified when the tasks require fundamentally different personas or isolated memory boundaries that would confuse a single context window.
