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

Default to a single agent with tools; only adopt multi-agent when you need isolated context windows, concurrent execution, or distinct system prompts/personas.

Journey Context:
Multi-agent systems introduce severe coordination overhead—context passing, routing failures, and state synchronization. A single agent with a robust tool library is significantly cheaper, faster, and less prone to hallucination for sequential tasks. Multi-agent is only justified when the cognitive load or context limits of a single agent are exceeded, or when tasks can genuinely run in parallel.
