Autogen Agent Definitions

Operator builds an AssistantAgent and passes the task instructions only via the first user message in team.run(task=...), leaving system_message at its default.

Put persistent role/persona/policy instructions in AssistantAgent(system_message=...) so they appear as the system turn on every model_client call. Use the task argument only for the per-run user instruction. Without system_message, the agent loses role anchoring on multi-turn loops because the mod…

UserProxyAgent runs with default max_consecutive_auto_reply and the AssistantAgent is in a tight tool-call/error/retry loop that never produces a terminating message.

Set max_consecutive_auto_reply to a concrete bound (e.g. 10) so the proxy stops auto-replying past the cap and surfaces control. Pair with a team-level termination condition (MaxMessageTermination) so neither agent runs forever even if the cap is raised.

Operator builds tools list once and mutates it (tools.append(new_tool)) between team.run() invocations, expecting the AssistantAgent to pick up the new tool.

AssistantAgent reads its tools at construction time; the live tools= list is not automatically refreshed mid-session. To add or remove tools, construct a new AssistantAgent (or use the documented dynamic-tool path). Mutating the input list after construction yields undefined behavior across version…
