 `command_code_working_directory` 决定 Command Code 能看到和操作的项目目录。`response_store_directory` 保存 `store: true` 的 Response；两个相对路径都以配置文件所在目录为基准。默认存储目录是隐藏目录 `.command-code-openai-bridge/responses`。`models.<name>.effort` 会传给 Command Code 的 `--effort`，Responses 请求中的 `reasoning.effort` 优先。可用 effort 由对应底层模型决定。服务强制只监听 `127.0.0.1`。客户端只能选择配置中的模型名，不能注入额外 CLI 参数。
 
+### Obsidian Copilot 流式输出

+在 Copilot 中添加自定义模型时使用：
+
+- Provider：`3rd party (openai-format)`
+- Base URL：`http://127.0.0.1:18000/v1`
+- API Key：任意非空文本
+- CORS：关闭
+- Streaming：开启
+
+Bridge 会直接响应浏览器 CORS 预检，包括 Copilot 和 OpenAI SDK 发送的自定义请求头及本机 Private Network Access。关闭 Copilot 的 CORS 绕过后，请求使用原生 `fetch`，可以读取 Bridge 返回的 SSE 流。
