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

Default to a single agent with a tool library; only use multi-agent if you need isolated context windows, divergent system prompts, or true parallel execution of independent sub-tasks.

Journey Context:
Multi-agent is often over-applied. Passing context between agents causes information loss \(the telephone game\) and high latency. A single agent retains the entire conversation and tool outputs in its context window. Multi-agent is only justified when a task requires conflicting system prompts \(e.g., coder vs. reviewer\) or when sub-tasks are completely independent and can run in parallel to save time.
