I tried three-tier systems, four-tier systems, agents talking to agents talking to agents. Agent A → Agent B → Agent C → ResultI use this for report generation: gather data → analyze → format → deliver. ┌→ Agent 1 ─┐ Task ─┼→ Agent 2 ─┼→ Voting/Merge → Result └→ Agent 3 ─┘I use this for sentiment analysis on important feedback. Primary Agent ├─ Subagent A │ ├─ Sub-subagent A1 │ └─ Sub-subagent A2 └─ Subagent BHonestly, I rarely use this. Break them into smaller chunks since no agent task should run longer than 30 seconds.
