+- An authenticated Codex CLI; the default integration uses `codex exec` and sends prompts through stdin
 - Google Chrome, or a compatible browser binary that supports `--headless=new`

+For direct `codex` calls, `mark2note` sends the prompt through stdin. Custom AI CLIs retain the legacy `-p <prompt>` invocation, so adjust their arguments to match your local setup.

-说明：请根据你本地 AI CLI 的实际调用方式调整参数，只要能被 `mark2note` 用来生成 deck JSON 即可。
+直连 `codex` 时，`mark2note` 会通过 stdin 传入 prompt。自定义 AI CLI 仍沿用原有的 `-p <prompt>` 调用方式，可按本机环境调整其他参数。
