json_schema not translate from OpenAI reponses API to Gemini or Gemini cli

[xyonium]

Is it a request payload issue?
[x] Yes, this is a request payload issue. I am using a client/cURL to send a request payload, but I received an unexpected error.
[ ] No, it's another issue.

Describe the bug
A clear and concise description of what the bug is.
通过openai responses api发送如下的请求，要求gemini提供json object，但是收到的是纯markdown。我搜索了代码，似乎只有在codex到openai处有解析json_schema这个字段，而这部分json_schema配置，在gemini api里是另外的格式，所以是否可以增加这部分转换，openai to gemini/gemini cli

CLI Type

gemini and gemini-cli and aistudio and vertex

Model Name

gemini-3.1-flash-lite

LLM Client

open webui with firecrawl
