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

Use a single agent with a rich tool/skill library unless you require parallel execution or strict context isolation.

Journey Context:
Multi-agent systems introduce massive overhead in state synchronization, context passing, and latency. If tasks are sequential and share the same domain, a single agent with tools is strictly superior due to zero message loss and lower token usage. Multi-agent is only justified when tasks are truly parallelizable, require fundamentally different system prompts, or need isolated memory boundaries to prevent context contamination.
