支持的 API：Chat Completions, Responses, and Anthropic Messages。
Anthropic Messages Use the native Anthropic shape, { "type": "advisor_20260301", "name": "advisor", "model": "<advisor model>" }. The model is the only setting it carries, so use openrouter:advisor on Chat Completions or Responses for instructions and the other parameters.
