[architecture] When to use multi-agent vs single-agent with tools

Default to a single agent with a tool/skill library; only introduce multiple agents if you need isolated context windows, distinct system prompts, or parallel execution.

Journey Context:
Multi-agent systems introduce massive coordination overhead: state synchronization, handoff latency, and context loss. A single agent with a large context window and diverse tools avoids these failure modes. Multi-agent is only justified when a task requires fundamentally different personas, safety boundaries, or when a single context window cannot hold the required state.
