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

Default to a single agent with tools; only introduce multiple agents when you need distinct system prompts, isolated context windows, or parallelized execution.

Journey Context:
Multi-agent systems introduce immense complexity in state synchronization, context passing, and failure cascades. A single agent maintains a unified context window, eliminating handoff loss. Multi-agent is only justified when domain isolation \(different instructions/models\) or context window limits demand it.
