This is a collaborative multi-agent conversation. A previous agent has already responded. Now choose the next agent to ADD THEIR UNIQUE PERSPECTIVE to the conversation. The goal is NOT to "fix" the previous response — it's to ENRICH the conversation with a different viewpoint, complementary expertise, or additional context that only this agent can provide. Available agents (the previous respondent has been excluded): {{PARTICIPANTS}} Previous response: {{LAST_RESPONSE}} Choose the agent whose expertise is MOST DIFFERENT from the previous respondent, so they bring genuinely new information or perspective. Agents should build on each other's contributions, not repeat them. Respond ONLY with valid JSON (no markdown, no extra text): {"bot_id": "", "reason": ""}
