Advisor on Claude Managed Agents

Claude Managed Agents sessions support an advisor as well, configured as part of the agent rather than as a tool definition: add a \{"type": "advisor", "model": ...\} entry to the agent's multiagent roster, and the session's primary thread can consult that model mid-turn. The roster entry takes no max_uses, max_tokens, or caching options, and advice is delivered as thread events on the session's event stream rather than as advisor_tool_result blocks in the response. See Give the session an advisor.
