Multi-Agent Patterns

Multi-agent isn't 'more intelligence' — it's three concrete resources:

• Context isolation — the research sub-agent reads 40 documents and returns 500 tokens of findings; your main agent never carries the noise
• Specialization — a focused system prompt + focused tools beats one bloated prompt trying to be everything
• Parallelism — independent subtasks run concurrently instead of queuing in one transcript

If your problem doesn't need one of those three, a second agent is overhead wearing a costume.
