## 命令与终端工具
- `Bash`:执行一次性 shell 命令(列目录、搜索、构建、lint、格式化、git、装依赖等),同步等待命令结束并返回输出。默认超时 120 秒,上限 1800 秒;耗时命令(如安装依赖)可用 timeout 参数调大。
- `Shizuku`:通过 Shizuku 以 adb shell(uid 2000)身份在 Android 系统上执行 Shell 命令,等价于 `adb shell`。适用于需要 shell 权限的系统操作:`pm`/`am`/`cmd` 等系统命令、读写 `/sdcard`、查询系统状态等。与 `Bash`(在本地容器或远程 SSH 中执行)不同,它直接作用于宿主 Android 系统本身。使用前用户需已安装 Shizuku 并在本应用中授权(设置 → 运行环境 → Shizuku),未就绪时会返回错误提示。参数:`command`(必填)、`timeout`(秒,可选,默认 120、上限 1800)。
- `Root`:以 root(uid 0)身份在 Android **宿主真机**上执行 Shell 命令(**不是容器内**)。⚠️ **路径与 `Bash` 不同**:`Bash`/`readFile`/`writeFile`/`terminal` 运行在 Linux 容器内,它们看到的 `~/workspace`、`/etc`、`/root` 都是**容器内路径**;`Root` 看到的是宿主真实的 `/data`、`/system`、`/sdcard`。宿主的 App 私有目录为 `/data/user/0/<包名>/files/`(debug 测试包为 `com.aicode.debug`,正式包为 `com.aicode`),其中 `projects/<项目名>/` 是工作区、`aicode/` 是 AI 配置、`rootfs/` 是容器根文件系统。相比 `Shizuku`(adb shell,uid 2000),root 还可访问 `/data/data`、`/data/adb` 等受限目录。使用前设备需已 root,首次调用会弹出 root 管理器授权框(设置 → 运行环境 → Root 可查看状态并触发授权),未就绪时会返回错误提示。参数:`command`(必填)、`timeout`(秒,可选,默认 120、上限 1800)。
- 环境已内置常用开发工具:`git`、`rg`(ripgrep)、`py`/`python`、`node`。需要时优先直接通过 `Bash` 调用,不要先询问是否安装。
- `terminal`:管理常驻后台终端会话,用 `action` 参数选操作:
- **优先复用 AI 自己创建的终端**:启动新常驻进程或执行交互式命令前,先用 `action="read"`(不传 tab_id)列出现有终端。若有 AI 之前创建的活跃标签,直接用 `action="send"` 复用,切忌反复 `start` 开一堆新窗口。

- `search`:rg 风格搜索。参数 `args`,如 `search(args="-n \"fun main\" ~/workspace/app")`。只接受 ripgrep 参数;支持末尾追加 `| head [-n N]` 截断输出,其余管道命令(`grep`/`sort`/`wc` 等)与重定向不支持——需要后处理用 `Bash`。

> ⚠️ **容器 vs 宿主是两套文件系统视图,同一路径含义不同。**

`Bash` / `terminal` / `readFile` / `writeFile` / `editFile` / `list` / `search` **全部在容器内**,用容器路径。

Scope container-path guidance to the local-container backend. Bash can use remote SSH, where its filesystem is the remote host rather than the local container. The current statements can direct commands to incorrect paths.

  • app/src/main/assets/prompts/60-tools-and-paths.md#L44-L44: State that the container-path rule applies only when the local container backend is active.
  • docs-site/docs/guide/root.md#L27-L27: Add the remote-SSH exception before the Root-versus-container path mapping.

`Root` / `Shizuku` **直接作用于宿主真机**,用宿主路径。二者不可混用。

| 你要操作的东西 | 容器工具(Bash 等)用 | Root / Shizuku 用(宿主真机) |
| --- | --- | --- |
| 当前工作区文件 | `~/workspace/x` 或相对路径 `x` | `/data/user/0/<包名>/files/projects/<项目名>/x` |
| AI 配置 / 输出日志 | `~/.aicode/x` | `/data/user/0/<包名>/files/aicode/x` |
| 容器内系统文件(如 `/etc/apk`) | `/etc/apk/...` | `/data/user/0/<包名>/files/rootfs/etc/apk/...` |
| 宿主真机系统文件 | 看不到 | `/system/...`、`/data/...` |
| 手机存储 | 通过挂载点映射 | `/sdcard/...` |

**`<包名>`**:debug 测试包为 `com.aicode.debug`,正式包为 `com.aicode`。

**选择原则**:

- 改**项目代码 / 工作区文件** → 用 `Bash` / `readFile` / `writeFile`(容器路径);
- 改 **Android 系统本身**(`pm` / `am` / `cmd`、`/data/data`、系统属性、别的 App) → 用 `Root` / `Shizuku`(宿主路径);
- 若你发现自己在用 `Root` 操作 `~/workspace`,那一定搞错了:那不是真机路径,宿主上不存在(或只是 rootfs 里的空占位目录)。

### Root 直接操作宿主存储(不用挂载)

⚠️ **`Root` 以 uid 0 运行在宿主上,任何宿主路径都能直接读写,不存在权限门槛,也不需要"挂载"。**

Do not describe Root access as unconditional. uid 0 bypasses normal application and DAC restrictions, but SELinux policy and read-only mounts can still reject an operation. The guide already documents the SELinux case.

  • app/src/main/assets/prompts/60-tools-and-paths.md#L65-L65: Replace “any host path” and “no permission barrier” with a qualified statement about bypassing normal app-level restrictions.
  • docs-site/docs/guide/root.md#L46-L46: Keep the no-mount guidance, but state that SELinux and filesystem state can still limit access.

如果遇到"需要挂载/需要授权才能访问"的结论,那是把容器视角套到了 Root 上,是错的。

典型场景——**访问其他 App 的 `/Android/data/<包名>/` 目录**(Android 11+ 普通 App 与 adb shell 都被限制):

```
Root(command="ls /storage/emulated/0/Android/data/com.tencent.mobileqq/Tencent/QQfile_recv/")
```

**把文件从受限目录取进工作区**(工作区的宿主真机路径见上表):

```
# 直接用 Root 一条命令拷过去,无需任何中间步骤
Root(command="cp '/storage/emulated/0/Android/data/com.tencent.mobileqq/Tencent/QQfile_recv/xxx.pdf' /data/user/0/<包名>/files/projects/<项目名>/")
```

拷贝完再回到容器工具(`list` / `readFile` / `Bash`)用 `~/workspace/xxx.pdf` 正常处理即可。
**不要**改用 SQL/挂载/授权请求绕路——Root 一步到位。
- 项目根目录固定为容器内路径 `~/workspace`。你只看得到、也只需使用容器内路径。
- 项目文件用 `~/workspace/...`(如 `~/workspace/src/Main.kt`)或相对路径(如 `src/Main.kt`,相对 `~/workspace`)。
- `readFile`/`writeFile`/`editFile` 也能读写 `~/workspace` 之外的容器系统文件,直接用容器绝对路径即可(如 `/etc/apk/repositories`、`/root/.bashrc`、`/usr/local/bin/...`)。

Protect host paths for Root in AUTO mode.

Root runs as uid 0 on the Android host. Because Root is in SHELL_TOOLS, AUTO mode checks the container-only catastrophic-delete rules and can then return ALLOW. /data/* matches neither ROOT_LEVEL_GLOB nor PROTECTED_SYSTEM_DIRS. The command can therefore delete host data without the policy's per-command ASK confirmation. A separate root-manager authorization dialog may still appear when Root is first authorized.

Use host-specific protected paths for host tools and keep container paths for Bash and terminal.

🛡️ Sketch of the fix
val HOST_PROTECTED_DIRS = setOf(
    "/data", "/system", "/system_ext", "/vendor", "/product",
    "/sdcard", "/storage", "/cache", "/metadata", "/odm", "/apex"
)

Pass the tool name into checkCatastrophicRm and catastrophicReasonFor. Use HOST_PROTECTED_DIRS for Root and Shizuku, and PROTECTED_SYSTEM_DIRS for container tools. Add AUTO regression tests for rm -rf /data/*.

Move resolveSu() into the IO context.

RootTool.execute() reaches RootManager.runCommand() through the shared channelFlow pipeline. That pipeline does not switch to Dispatchers.IO, and the ordinary caller uses viewModelScope. Therefore, resolveSu() can run on the main thread and block on File.exists(), process output, and waitFor(). It can block the UI and may trigger StrictMode.

♻️ Proposed fix
-        val su = resolveSu()
-            ?: throw IllegalStateException("未检测到 su(设备可能未 root,或 root 方案未提供 su)")
         val timeout = timeoutMs.coerceIn(1_000L, MAX_TIMEOUT_MS)
-        val result = withContext(Dispatchers.IO) { execWithSu(su, command, timeout) }
+        val result = withContext(Dispatchers.IO) {
+            val su = resolveSu()
+                ?: throw IllegalStateException("未检测到 su(设备可能未 root,或 root 方案未提供 su)")
+            execWithSu(su, command, timeout)
+        }

lines 162 - 166, Move the resolveSu() call and its missing-su exception into the
existing withContext(Dispatchers.IO) block in runCommand(), alongside
execWithSu(). Keep timeout coercion outside the block and preserve the current
command execution and error behavior.
