+                "- Use {py:class}`~autogen_agentchat.conditions.ExternalTermination` when your application observes saturation, provider rate limits, or queue growth outside the team and needs to stop the run programmatically.\n",
+                "- Implement a custom termination condition when overload is visible in the messages produced by your agents or tools, for example when a tool returns a rate-limit result or a caller receives too many retry requests.\n",
