通过 RepoBrain CLI 询问当前工作区：

> $ARGUMENTS

Use Bash:

RB_ASK_TIMEOUT_SECONDS="${RB_ASK_TIMEOUT_SECONDS:-120}" rb-ask "$ARGUMENTS" --workspace "$PWD"

If `.env` sets `RB_HOST_RUNNER=codex`, the same command uses the user's local Codex CLI login for `rb-ask` instead of an API key. This host-runner mode is ask-only; refresh should use scan-only artifacts or a configured `OPENAI_*` provider.

如果 `.env` 设置了 `RB_HOST_RUNNER=codex`，同一个命令会通过用户本机 Codex CLI 登录运行 `rb-ask`，不走 API key。这个 host-runner 模式只支持 ask；refresh 应使用 scan-only 产物或已配置的 `OPENAI_*` provider。

使用 Bash：

RB_ASK_TIMEOUT_SECONDS="${RB_ASK_TIMEOUT_SECONDS:-120}" rb-ask "$ARGUMENTS" --workspace "$PWD"

If `rb-ask` is not found, tell the user the engine CLI is not installed and suggest:

如果找不到 `rb-ask`，说明 engine CLI 尚未安装，建议用户运行：

pipx install "git+https://github.com/study8677/repobrain.git#subdirectory=engine"

Prefer `rb-ask` over manual file search. If the answer returns insufficient detail, follow up with targeted Read/Grep.

优先使用 `rb-ask`，不要先手动搜索文件。如果返回的信息不够，再用有目标的 Read/Grep 补充。
