+# Disk Insight (`disk-insight`)
+
+English | [简体中文](README.zh-CN.md)
+
+A disk space viewer and cleaner for macOS and Windows. Choose a disk or a folder, and Disk Insight
+shows where the space went: a sunburst space map, junk files sorted by how safe they are to remove,
+large and duplicate files, and how much your code repositories and their Git worktrees take. You can
+ask an Agent what an item is before deciding. Items you select are **deleted permanently** after a
+confirmation dialog that lists them; nothing goes to the Trash or Recycle Bin. The interface is in
+Chinese.
+
+The previews below use synthetic data.
+
+![Space map: disks, sunburst and folder list](docs/preview-map.png)
+
+![Junk cleanup: reclaimable space by category and the cleanup tiers](docs/preview-junk.png)
+
+## What you can do
+
+- **Space map** (空间地图, the home view): a sunburst of the scanned scope next to the current
+  folder's children, with search and sort. Click to drill down. The "文件类型" switch totals the
+  space by file type (video, images, audio, disk images, archives, installers, virtual machine disks,
+  development caches, other).
+- **Explicit scope**: nothing is scanned until you choose what to scan, one or more disks or folders.
+  Pick a folder with the system folder dialog or paste its path. A quick pass shows the first
+  results while the full scan continues.
+- **Junk cleanup** (垃圾清理): rule-based categories such as temporary files, package manager
+  caches, browser caches, logs, build outputs, old installers, app and chat caches, Python virtual
+  environments, simulators, large old files and duplicates, in three tiers:
+  - **建议清理** (recommended): rebuilt automatically after deletion, selected by default (build
+    outputs only when their project has not changed for 90 days).
+  - **需要确认** (needs review): may lose information, never selected by default.
+  - **仅提示** (info only): system junk, the Trash or Recycle Bin, Docker disk images and the Go
+    module cache. Shown with their size and how to clean them elsewhere; they cannot be selected.
+
+  A pie chart shows reclaimable space by category. The list has search, sort, and an ignore list
+  (忽略名单) for items you never want suggested again.
+- **Large and duplicate files** (大文件与重复文件): files of 500 MB or more; duplicates of 1 MB or
+  more, confirmed by SHA-256, with "每组只保留最新的一份" (keep only the newest copy in each group).
+  Files inside Git work trees are not compared.
+- **Code repositories** (代码仓库): each repository's size, its worktrees (count and size), Git data
+  and dependencies. "勾选依赖和构建产物" selects a repository's dependencies and build outputs.
+  "清理失效 worktree" removes worktree records whose folder no longer exists. A worktree with
+  uncommitted changes or unpushed commits is locked and cannot be selected.
+- **Ask the Agent** (问 Agent): on any item, ask an Agent what it is, what deleting it would break,
+  and whether to delete it. The answer streams into a side panel.
+- **Clean history and stats**: every deleted item with its time, size and result (更多 → 清理记录),
+  and the total space freed and number of cleanups in the header.
+- **Folders without permission** (更多 → 无权限的目录): the folders the scan could not read. On
+  macOS the page explains how to grant Full Disk Access and opens that System Settings page.
+- Reveal an item in Finder or File Explorer, and Quick Look a file (macOS). The theme follows the
+  system.
+
+## Install
+
+Requires MiniMax Code 3.1.2 or later, because the package declares `agentAccess`,
+`agentConcurrency` and `surface.window` (the size of the pop-out window); earlier versions cannot
+install it.
+
+Copy this directory, including the hidden `.minimax-plugin/`, into the MiniMax Code plugins
+directory as `disk-insight/` (`~/.minimax/plugins/disk-insight/` by default; see the root README's
+Install section). Restart MiniMax Code, then open "磁盘透视" from the Mini App entry in the right
+panel or ask the Agent to "打开磁盘透视".
+
+On macOS, give MiniMax Code Full Disk Access (System Settings → Privacy & Security → Full Disk
+Access) and restart it to scan everything. Without it, protected folders are listed as unreadable
+and their space is counted as "未扫描或无权限".
+
+## Tested environment
+
+- MiniMax Code 3.1.3-preview.4684 (an internal preview build) on macOS 27.0 (Apple Silicon).
+  Installed through the Host publish flow and opened in the right panel.
+- A full scan of the home directory with Full Disk Access granted: about 762 GB and about 73
+  million files; peak memory of the Mini App process 561 MB. The quick scan showed its first results
+  in about 0.2 seconds.
+- Code repositories: the detected worktrees matched `git worktree list` (58 in one repository).
+  "清理失效 worktree" was run once on a real repository; it removed 13 stale records, checked with
+  git afterwards.
+- Permanent deletion was run in the real desktop app on five `__pycache__` folders in a project
+  untouched for more than 170 days. Afterwards the folders were gone, the `.py` files were still
+  there, and the Git status was clean. An end-to-end test also deletes a folder containing symbolic
+  links that point outside it; all link targets are left intact.
+- Ask the Agent: run three times with a real Agent, the last one with the current prompt layout
+  (the data section described under Data & access); the answer kept the three-part format.
+- The list of folders without permission was checked before and after granting Full Disk Access.
+  Quick Look and Reveal in Finder were tried. In the system folder dialog, both cancelling and
+  choosing a folder were tried; the chosen folder was added to the scope.
+- The dark theme was checked in the real desktop app with MiniMax Code's appearance set to dark:
+  space map, junk cleanup, code repositories and the clean history dialog. The page follows MiniMax
+  Code's appearance setting, not the macOS one.
+- 53 unit tests, all passing (`npm test` in this directory).
+- Not yet verified: everything on Windows; how long deleting a very large `node_modules` takes;
+  permission requests during a real Agent run (with the permission mode set to ask, the Agent only
+  ran read-only commands and no request appeared, so the permission cards are checked only against
+  a mock Agent).
+
+## Data & access
+
+- **State**: everything Disk Insight stores is under the Host-provided `context.dataDir`. Each file
+  is written to a `.tmp` file first and then renamed.
+  - `scan-v4.ndjson.gz`: the last scan result as gzip-compressed NDJSON: the scanned folder tree
+    with sizes, the items found, duplicate groups, repositories and worktrees. It contains the paths
+    of scanned files and folders.
+  - `selection-v1.json`: the current selection (item ids and paths).
+  - `history-v1.json`: the clean history: time, path, freed size and result of each deleted item.
+  - `stats-v1.json`: total space freed, number of cleanups, and the last cleanup's summary.
+  - `scope-v1.json`: the last scan scope (disk ids and folder paths).
+  - `ignore-v1.json`: the ignore list (paths).
+
+  The page keeps nothing in `localStorage` or other browser storage.
+- **Files read**:
+  - Everything inside the scope you choose: the metadata of every file and folder (`lstat`: name,
+    size, timestamps, device and inode), not the contents. Symbolic links and junctions are not
+    followed. A whole-disk scan on macOS skips `/System/Volumes`, `/Volumes`, `/dev`, `/net`,
+    `/home`, `/.vol`, `/.resolve` and `/.nofollow`. iCloud Drive (`~/Library/Mobile Documents`),
+    `~/Library/CloudStorage` and OneDrive folders are not listed at all, because listing them can
+    trigger cloud downloads.
+  - Duplicate detection reads file contents to hash them: the first and last 64 KB of files of the
+    same size, then the whole file (SHA-256) when those match. Only files of 1 MB or more are
+    compared; files in Git work trees, caches and build outputs, protected folders, `~/Library` and
+    the macOS system folders (macOS), and `AppData` (Windows) are skipped.
+  - Git metadata of repositories in the scope: a worktree's or submodule's `.git` file,
+    `<git dir>/worktrees/*/gitdir`, `HEAD` (for the branch name), and the modification time of
+    `<git dir>/index` (last activity). `git status` also reads the work tree (see Processes).
+  - The Trash (`~/.Trash`) and Recycle Bin are only measured.
+  - The fixed locations of the cleanup rules, listed in `miniapp/node/rules.mjs` (macOS) and
+    `miniapp/node/rules-win.mjs` (Windows): for example `~/Library/Caches`, `~/Library/Logs`,
+    `~/.npm`, Xcode `DerivedData`, chat app folders under `~/Library/Containers` and
+    `~/Library/Application Support`, `/Library/Caches` and `/private/var/log` on macOS;
+    `%TEMP%`, caches under `%LOCALAPPDATA%` and `%APPDATA%`, chat app folders under
+    `%USERPROFILE%\Documents`, and `%SystemRoot%\SoftwareDistribution\Download` on Windows. At the
+    start of a scan each location is checked with `realpath`, and the folders that a `*` stands for
+    (for example one per chat account) are listed.
+  - Other fixed locations: `~/Library/Safari` and `~/Library/Mail` are listed only to check whether
+    Full Disk Access is granted; `/usr/share/firmlinks`, `/System/Volumes/Data` and `/Volumes` to
+    find the data volume and other disks; the home, Desktop, Downloads and Documents folders are
+    checked for existence to offer them as scope shortcuts.
+  - The MiniMax Code data directory is located from `context.dataDir`: the nearest parent folder
+    whose name starts with `.minimax`, or `~/.minimax` when there is none. This relies on an
+    unspecified layout. It is used only to add that directory to the protection list; nothing in it
+    is read.
+  - A folder you type or pick is checked with `realpath` and `stat` before it is accepted. For
+    "问 Agent", the item's largest children come from the scan result; when the scan did not keep
+    them, the folder is listed on the spot (at most 2,000 entries and 20,000 `lstat` calls).
+- **Files deleted or written outside `dataDir`**:
+  - Cleaning **permanently deletes** the items you selected and confirmed, with `fs.rm`
+    (recursive; symbolic links are removed themselves and never followed, so their targets are left
+    intact). Nothing goes to the Trash or Recycle Bin, there are no backups, and deleted items cannot
+    be restored.
+  - Protected paths can never be selected or deleted: system folders (macOS `/System`, `/Library`,
+    `/usr`, `/bin`, `/sbin`, `/private`, Safari and `/Applications/Utilities`; Windows
+    `%SystemRoot%`, `Program Files`, `Program Files (x86)`, `ProgramData`, `%APPDATA%\Microsoft`, and
+    `System Volume Information`, `$Recycle.Bin`, `pagefile.sys`, `hiberfil.sys`, `swapfile.sys` on
+    every disk), credentials (`~/Library/Keychains`, `~/.ssh`, `~/.gnupg`), cloud drives (iCloud
+    Drive, `~/Library/CloudStorage`, OneDrive), the Trash, the Go module cache, the MiniMax Code data
+    directory, this Mini App's own `dataDir`, every `.git` folder itself, disk roots, and any folder
+    that contains a protected path. The home folder, `~/Library` (Windows: `AppData` and its `Local`,
+    `LocalLow` and `Roaming` folders) and the standard Desktop, Documents, Downloads, Pictures,
+    Movies or Videos, and Music folders are protected themselves; items inside them can be selected.
+  - Right before deleting each item, Disk Insight checks five things again and skips the item if
+    any of them fails: the path exists; it is not a symbolic link, and its device, inode and
+    modification time match the scan; its `realpath` equals the scanned path; it is not locked; its
+    disk allows deletion.
+  - Items on external and network disks are only scanned, never deleted.
+  - The confirmation dialog lists every selected item and says the deletion cannot be undone. Items
+    that contain a Git repository or chat files are listed one by one with a warning; the others are
+    grouped by source.
+  - "清理失效 worktree" runs `git -C <main repository> worktree prune` after you confirm the list of
+    stale records in a dialog. Git removes only records whose worktree folder no longer exists.
+- **Processes**: every command is started with an argument array (`child_process.spawn` or
+  `execFile`), never through a shell, and with a timeout; `dispose` ends those still running. A
+  command line holds only fixed text and paths taken from the scan result (the page sends item ids,
+  not paths).
+
+  | Command | Platform | When and why |
+  | --- | --- | --- |
+  | `/bin/df -k <volume>` | macOS | Listing disks: each volume's used and free space. |
+  | `/sbin/mount` | macOS | Listing disks, when `/Volumes` holds other volumes: tells external disks from network disks. |
+  | `/bin/ps -axco comm` | macOS | After a scan: marks caches of running apps as in use. |
+  | `tasklist.exe /fo csv /nh` | Windows | Same as `ps`. |
+  | `powershell.exe -NoProfile -NonInteractive -Command "Get-CimInstance Win32_LogicalDisk \| Select-Object DeviceID,DriveType,Size,FreeSpace,VolumeName \| ConvertTo-Json -Compress"` | Windows | Listing disks. |
+  | `go env GOMODCACHE` | both | Once, when the page first loads: finds the Go module cache to protect it. Tries `go` on `PATH`, then `/usr/local/go/bin/go`, `/opt/homebrew/bin/go`, `/usr/local/bin/go` (Windows: `go.exe`, `C:\Program Files\Go\bin\go.exe`), with `GOTOOLCHAIN=local` so it never downloads a toolchain, run in `dataDir`. Falls back to `$GOPATH/pkg/mod`, then `~/go/pkg/mod`. |
+  | `/usr/bin/xcode-select -p` | macOS | Before using `/usr/bin/git`: makes sure the Command Line Tools exist, so macOS does not pop up an install prompt. Git is looked up on `PATH`, then in `/opt/homebrew/bin`, `/usr/local/bin` and `/usr/bin` (Windows: `git` on `PATH`). |
+  | `git -C <worktree> status --porcelain=v1 --branch` | both | "检查状态" in the repository view, and before a worktree can be selected: finds uncommitted changes and unpushed commits. Run with `GIT_OPTIONAL_LOCKS=0` and `GIT_TERMINAL_PROMPT=0`, at most four at a time. |
+  | `git -C <main repository> worktree prune` | both | After you confirm "清理失效 worktree": removes stale worktree records. |
+  | `/usr/bin/open -R <path>` | macOS | "在访达中显示". |
+  | `/usr/bin/open x-apple.systempreferences:com.apple.settings.Storage` | macOS | "打开存储设置" on the system junk category. |
+  | `/usr/bin/open x-apple.systempreferences:com.apple.preference.security?Privacy_AllFiles` | macOS | Opens the Full Disk Access page. |
+  | `/usr/bin/osascript -e 'POSIX path of (choose folder with prompt "选择要扫描的文件夹")'` | macOS | The folder dialog. The script is fixed. |
+  | `/usr/bin/qlmanage -p <file>` | macOS | Quick Look; closed after 10 minutes at most. |
+  | `powershell.exe -STA -NoProfile -Command <script>` | Windows | The folder dialog. The script is a fixed `FolderBrowserDialog` script; the chosen path comes back base64-encoded. |
+  | `explorer.exe /select,"<path>"` | Windows | Reveal in File Explorer. The path is passed as one verbatim argument. |
+  | `explorer.exe ms-settings:storagesense` | Windows | Opens Storage settings. Exposed as a system action route; the page does not offer it at present. |
+  | `cleanmgr.exe` | Windows | "打开磁盘清理" on the system junk category. |
+- **Network**: none. The Node process only serves the page on `context.listen`, and the page only
+  calls its own relative routes.
+- **Agent turns** (`agentAccess: ["session.run"]`, `agentConcurrency: 2`): each "问 Agent" runs one
+  Agent turn from the page, in a new session. The prompt holds the item's path, the operating
+  system, its size and reclaimable size, last modification date, scan category and what deleting it
+  does, its tags (contains a Git repository, chat files, possibly in use), and up to 10 of its
+  largest children with sizes. Paths and names read from disk are untrusted: they go into a section
+  between `<<<条目信息` and `条目信息>>>` markers that the prompt labels as data only, each one
+  written as an escaped JSON string (so a file name cannot add a line or a fake end marker), and the
+  Agent is told not to follow any instruction found there. It asks the Agent only to analyse: not to
+  delete, move or modify any file, nor run commands that change files (read-only commands to look at
+  the folder are allowed);
+  to answer in three parts (what it is, what deleting it does, a recommendation with the reason); to
+  say so when unsure; and to reply in the language of the request in at most 300 characters. The
+  Agent keeps its normal abilities (files, shell, MCP), so that instruction is a request, not a
+  sandbox. Disk Insight never acts on the answer.
+- **Permissions**: every permission request in an ask is shown as a card with "允许一次" (allow once)
+  and "拒绝" (deny). Disk Insight never answers a request on its own: the buttons relay your click
+  for that one request, and nothing happens until you click. A question from the Agent is shown with
+  a pointer to "在对话中打开", which opens the session in the chat side panel. "停止" cancels the
+  turn.
+- The Agent's answer is rendered as a safe Markdown subset: the text is HTML-escaped first, then
+  headings, lists, quotes, code, bold and italics become fixed tags; links are shown as text with
+  their URL and never become clickable.

+- **必须先选扫描范围**：不选范围就不扫描。范围可以是一个或多个磁盘，也可以是文件夹；文件夹可以用系统的文件夹选择框选，也可以直接粘贴路径。快速扫描先出第一批结果，完整扫描在后台继续。
+- **垃圾清理**：按规则识别临时文件、包管理器缓存、浏览器缓存、日志、开发构建产物、旧安装包、应用和聊天软件缓存、Python 虚拟环境、模拟器、大且久未修改的文件、重复文件等，分三档：
+  - **建议清理**：删除后会自动重建，默认勾选（开发构建产物只在所在项目 90 天没改动时才默认勾选）。
+  - **需要确认**：可能丢失信息，默认不勾选。
+  - **仅提示**：系统垃圾、废纸篓或回收站、Docker 磁盘镜像、Go 模块缓存。只显示大小和去哪里处理，不能勾选。
+
+  有按分类统计可释放空间的饼图，列表支持搜索、排序，还有忽略名单，不想再被建议的条目可以放进去。
+- **大文件与重复文件**：500 MB 及以上的文件；1 MB 及以上的重复文件，用 SHA-256 确认内容相同，可以「每组只保留最新的一份」。Git 工作区里的文件不参与比对。
+- **代码仓库**：每个仓库的大小、worktree 数量和大小、Git 数据和依赖的占用。「勾选依赖和构建产物」把仓库里的依赖和构建产物加入已选清单；「清理失效 worktree」删除目录已经不存在的 worktree 记录。有未提交改动或未推送提交的 worktree 会锁定，不能勾选。
+- **问 Agent**：任何条目都可以问 Agent 这是什么、删了会怎样、建不建议删，回答实时显示在侧边面板里。
+- **清理记录和统计**：每个被删条目的时间、大小和结果（更多 → 清理记录），页头显示累计释放的空间和清理次数。
+- **无权限的目录**（更多 → 无权限的目录）：列出扫描时读不了的目录。在 macOS 上会说明怎么开启完全磁盘访问权限，并可以直接打开系统设置的对应页面。
+- 在访达或资源管理器中显示条目，快速预览文件（macOS）。主题跟随系统。
+
+## 安装
+
+需要 MiniMax Code 3.1.2 或更高版本，因为包里声明了 `agentAccess`、`agentConcurrency` 和 `surface.window`（弹出窗口的尺寸），更早的版本无法安装。
+
+把整个目录（包括隐藏的 `.minimax-plugin/`）复制到 MiniMax Code 的插件目录，命名为 `disk-insight/`（默认是 `~/.minimax/plugins/disk-insight/`，见根目录 README 的安装说明）。重启 MiniMax Code，在右侧面板的 Mini App 入口打开「磁盘透视」，或者让 Agent「打开磁盘透视」。
+
+在 macOS 上要扫全，需要给 MiniMax Code 开启完全磁盘访问权限（系统设置 → 隐私与安全性 → 完全磁盘访问权限）并重启。没开时，受保护的目录会列为无权限读取，占用的空间算在「未扫描或无权限」里。
+
+## 测试环境
+
+- macOS 27.0（Apple Silicon）上的 MiniMax Code 3.1.3-preview.4684（内部预览版）。通过宿主的发布流程安装，在右侧面板打开。
+- 授予完全磁盘访问权限后，对主目录做过完整扫描：约 762 GB、约 7,300 万个文件，Mini App 进程内存峰值 561 MB。快速扫描约 0.2 秒出第一批结果。
+- 代码仓库：识别出的 worktree 和 `git worktree list` 对照一致（一个仓库 58 个）。「清理失效 worktree」在真实仓库执行过一次，删了 13 条失效记录，事后用 git 复查过。
+- 永久删除在真实桌面端执行过：一个 170 多天没动过的项目里的 5 个 `__pycache__` 目录。删后目录不存在，`.py` 文件还在，git 状态干净。另外有一个端到端测试：被删目录里有指向目录外的符号链接，删完后链接目标都完好。
+- 问 Agent 用真实 Agent 跑过三次，最后一次用的是当前提示词格式（Data & access 里说的数据段），回答仍按三段格式。
+- 无权限目录列表在授权前、授权后都看过。快速预览、在访达中显示都试过。系统文件夹选择框里取消和选中文件夹都试过，选中的文件夹会加入扫描范围。
+- 深色主题：把 MiniMax Code 的外观设成深色后，在真实桌面端检查了空间地图、垃圾清理、代码仓库和清理记录弹窗。页面跟随的是 MiniMax Code 的外观设置，不是 macOS 的系统外观。
+- 单元测试 53 个，全部通过（在本目录运行 `npm test`）。
+- 尚未验证：Windows 上的全部功能；删除特别大的 `node_modules` 的耗时；真实 Agent 运行中出现权限请求的情况（把权限模式改成逐项询问后，Agent 只运行了只读命令，没有出现权限请求，所以权限卡片只用模拟的 Agent 测过）。
+
+## 数据与访问
+
+- **状态**：磁盘透视存的所有数据都在宿主提供的 `context.dataDir` 下。每个文件都先写临时文件 `.tmp`，再改名替换。
+  - `scan-v4.ndjson.gz`：上一次的扫描结果（gzip 压缩的 NDJSON），包括扫描到的目录树和大小、识别出的条目、重复文件分组、代码仓库和 worktree，里面有被扫描文件和目录的路径。
+  - `selection-v1.json`：已选清单（条目编号和路径）。
+  - `history-v1.json`：清理记录，每个被删条目的时间、路径、释放大小和结果。
+  - `stats-v1.json`：累计释放空间、清理次数、上一次清理的汇总。
+  - `scope-v1.json`：上一次的扫描范围（磁盘编号和文件夹路径）。
+  - `ignore-v1.json`：忽略名单（路径）。
+
+  页面不在 `localStorage` 或其他浏览器存储里保存任何东西。
+- **读取的文件**：
+  - 所选范围里的全部文件和目录的元数据（`lstat`：名称、大小、时间、设备号和 inode），不读内容。不跟随符号链接和目录联接。macOS 上扫描整个磁盘时跳过 `/System/Volumes`、`/Volumes`、`/dev`、`/net`、`/home`、`/.vol`、`/.resolve`、`/.nofollow`。iCloud 云盘（`~/Library/Mobile Documents`）、`~/Library/CloudStorage` 和 OneDrive 目录完全不列，因为列目录可能触发云端下载。
+  - 重复文件比对会读文件内容来算哈希：先读同样大小的文件头尾各 64 KB，对得上再读全文算 SHA-256。只比对 1 MB 及以上的文件；Git 工作区、缓存和构建产物、受保护的目录、`~/Library` 和 macOS 系统目录（macOS）、`AppData`（Windows）里的文件都跳过。
+  - 范围内代码仓库的 Git 元数据：worktree 或子模块的 `.git` 文件、`<git 目录>/worktrees/*/gitdir`、`HEAD`（取分支名）、`<git 目录>/index` 的修改时间（最近活动）。`git status` 还会读工作区（见「进程」）。
+  - 废纸篓（`~/.Trash`）和回收站只统计大小。
+  - 清理规则里的固定位置，完整列表见 `miniapp/node/rules.mjs`（macOS）和 `miniapp/node/rules-win.mjs`（Windows）。例如 macOS 上的 `~/Library/Caches`、`~/Library/Logs`、`~/.npm`、Xcode 的 `DerivedData`、`~/Library/Containers` 和 `~/Library/Application Support` 下的聊天软件目录、`/Library/Caches`、`/private/var/log`；Windows 上的 `%TEMP%`、`%LOCALAPPDATA%` 和 `%APPDATA%` 下的缓存、`%USERPROFILE%\Documents` 下的聊天软件目录、`%SystemRoot%\SoftwareDistribution\Download`。每次扫描开始时用 `realpath` 确认这些位置是否存在，并列出规则路径里 `*` 代表的目录（例如每个聊天账号一个目录）。
+  - 其他固定位置：只为判断有没有完全磁盘访问权限而列 `~/Library/Safari` 和 `~/Library/Mail`；为找数据卷和其他磁盘读 `/usr/share/firmlinks`、`/System/Volumes/Data` 和 `/Volumes`；检查主目录、桌面、下载、文稿这几个文件夹是否存在，作为扫描范围的快捷选项。
+  - MiniMax Code 数据目录从 `context.dataDir` 推出来：往上找第一个名字以 `.minimax` 开头的目录，找不到就用 `~/.minimax`。这依赖未公开约定的目录布局。推出来的目录只用来加进保护名单，不读里面的任何文件。
+  - 输入或选择的文件夹会先用 `realpath` 和 `stat` 检查后才接受。「问 Agent」用到的最大子项取自扫描结果；扫描结果里没有时当场列一次目录（最多 2,000 项、20,000 次 `lstat`）。
+- **删除或写入 `dataDir` 以外的文件**：
+  - 清理会**永久删除**你勾选并确认的条目，用 `fs.rm` 递归删除；符号链接只删链接本身，不跟随，链接指向的文件和目录不受影响。不进废纸篓或回收站，不做备份，删了不能恢复。
+  - 受保护的路径不能勾选，也不会被删除：系统目录（macOS 的 `/System`、`/Library`、`/usr`、`/bin`、`/sbin`、`/private`、Safari、`/Applications/Utilities`；Windows 的 `%SystemRoot%`、`Program Files`、`Program Files (x86)`、`ProgramData`、`%APPDATA%\Microsoft`，以及每个磁盘上的 `System Volume Information`、`$Recycle.Bin`、`pagefile.sys`、`hiberfil.sys`、`swapfile.sys`）、凭据（`~/Library/Keychains`、`~/.ssh`、`~/.gnupg`）、云盘（iCloud 云盘、`~/Library/CloudStorage`、OneDrive）、废纸篓、Go 模块缓存、MiniMax Code 数据目录、本 Mini App 自己的 `dataDir`、所有 `.git` 目录本身、磁盘根目录，以及包含受保护路径的目录。主目录、`~/Library`（Windows 上是 `AppData` 及其 `Local`、`LocalLow`、`Roaming`）和标准的桌面、文稿、下载、图片、影片或视频、音乐文件夹只保护本身，里面的条目可以勾选。
+  - 每一项删除前当场复查五项，任何一项不通过就跳过：路径存在；不是符号链接，设备号、inode 和修改时间都和扫描时一致；`realpath` 和扫描到的路径一致；没有被锁定；所在磁盘允许删除。
+  - 外接盘和网络盘上的条目只扫描，不删除。
+  - 确认框列出全部已选条目，并写明删除后不能恢复。含 Git 仓库或聊天文件的条目逐条列出并带提示，其余按来源分组。
+  - 「清理失效 worktree」在你确认失效记录清单后执行 `git -C <主仓库> worktree prune`，Git 只删除 worktree 目录已经不存在的记录。
+- **进程**：所有命令都用参数数组启动（`child_process.spawn` 或 `execFile`），不经过 shell，都有超时；`dispose` 时结束还在运行的进程。命令行里只有固定文本和取自扫描结果的路径（页面传的是条目编号，不是路径）。
+
+  | 命令 | 平台 | 时机和用途 |
+  | --- | --- | --- |
+  | `/bin/df -k <卷>` | macOS | 列磁盘：读每个卷的已用和可用空间。 |
+  | `/sbin/mount` | macOS | 列磁盘，`/Volumes` 下有其他卷时：区分外接盘和网络盘。 |
+  | `/bin/ps -axco comm` | macOS | 扫描结束后：给正在运行的应用的缓存加上「可能被占用」标签。 |
+  | `tasklist.exe /fo csv /nh` | Windows | 同 `ps`。 |
+  | `powershell.exe -NoProfile -NonInteractive -Command "Get-CimInstance Win32_LogicalDisk \| Select-Object DeviceID,DriveType,Size,FreeSpace,VolumeName \| ConvertTo-Json -Compress"` | Windows | 列磁盘。 |
+  | `go env GOMODCACHE` | 两者 | 页面第一次加载时运行一次：找到 Go 模块缓存并加进保护名单。依次尝试 `PATH` 里的 `go`、`/usr/local/go/bin/go`、`/opt/homebrew/bin/go`、`/usr/local/bin/go`（Windows 是 `go.exe`、`C:\Program Files\Go\bin\go.exe`），设置 `GOTOOLCHAIN=local` 避免下载工具链，在 `dataDir` 里执行。找不到时用 `$GOPATH/pkg/mod`，再不行用 `~/go/pkg/mod`。 |
+  | `/usr/bin/xcode-select -p` | macOS | 使用 `/usr/bin/git` 之前：确认装了命令行工具，避免系统弹出安装提示。git 按 `PATH`、`/opt/homebrew/bin`、`/usr/local/bin`、`/usr/bin` 的顺序查找（Windows 用 `PATH` 里的 `git`）。 |
+  | `git -C <worktree> status --porcelain=v1 --branch` | 两者 | 代码仓库视图里点「检查状态」时，以及勾选 worktree 之前：检查有没有未提交的改动和未推送的提交。带 `GIT_OPTIONAL_LOCKS=0`、`GIT_TERMINAL_PROMPT=0`，同时最多 4 个。 |
+  | `git -C <主仓库> worktree prune` | 两者 | 你确认「清理失效 worktree」后：删除失效的 worktree 记录。 |
+  | `/usr/bin/open -R <路径>` | macOS | 「在访达中显示」。 |
+  | `/usr/bin/open x-apple.systempreferences:com.apple.settings.Storage` | macOS | 系统垃圾分类上的「打开存储设置」。 |
+  | `/usr/bin/open x-apple.systempreferences:com.apple.preference.security?Privacy_AllFiles` | macOS | 打开完全磁盘访问权限设置页。 |
+  | `/usr/bin/osascript -e 'POSIX path of (choose folder with prompt "选择要扫描的文件夹")'` | macOS | 文件夹选择框，脚本固定。 |
+  | `/usr/bin/qlmanage -p <文件>` | macOS | 快速预览，最多开 10 分钟。 |
+  | `powershell.exe -STA -NoProfile -Command <脚本>` | Windows | 文件夹选择框。脚本是固定的 `FolderBrowserDialog` 脚本，选中的路径用 base64 传回。 |
+  | `explorer.exe /select,"<路径>"` | Windows | 在资源管理器中显示，路径作为一个原样参数传入。 |
+  | `explorer.exe ms-settings:storagesense` | Windows | 打开存储设置。只作为系统操作接口存在，页面目前没有入口。 |
+  | `cleanmgr.exe` | Windows | 系统垃圾分类上的「打开磁盘清理」。 |
+- **网络**：无。Node 进程只在 `context.listen` 上提供页面，页面只请求自己的相对路径接口。
+- **Agent 运行**（`agentAccess: ["session.run"]`，`agentConcurrency: 2`）：每次「问 Agent」由页面发起一次 Agent 运行，每次都是新会话。提示词里有条目的路径、操作系统、大小和可释放大小、最后修改时间、扫描分类和删了会怎样、标签（含 git 仓库、聊天软件文件、可能被正在运行的程序占用），以及最多 10 个最大的子项和大小。从磁盘读到的路径和名称不可信：它们放在 `<<<条目信息` 和 `条目信息>>>` 两个标记之间，提示词标明这一段只是数据；每个路径和名称都写成转义过的 JSON 字符串，文件名没法多出一行或伪造结束标记；并告诉 Agent 不要照其中的任何指令做。提示词要求 Agent 只做分析：不删除、移动、修改任何文件，也不运行会改动文件的命令（确实需要时可以用只读命令查看目录结构）；按「这是什么、删了会怎样、建议和理由」三段回答；判断不了就说不确定；用与请求相同的语言回答，不超过 300 字。Agent 保留正常的能力（文件、Shell、MCP），所以这只是要求，不是沙箱。磁盘透视不会根据回答做任何操作。
+- **权限**：问 Agent 过程中的每个权限请求都以卡片显示，有「允许一次」和「拒绝」两个按钮。磁盘透视从不自己回复请求：按钮只把你对这一个请求的点击转给宿主，你不点就一直等着。Agent 提问时会提示你点「在对话中打开」，在聊天侧栏里打开这个会话继续。「停止」会取消这次运行。
+- Agent 的回答按安全的 Markdown 子集渲染：先整段做 HTML 转义，再把标题、列表、引用、代码、粗体和斜体换成固定标签；链接只显示文字和网址，不能点击。

+ * App's own Agent directory; a continued session keeps its directory. A new session takes the
+ * model and thinking level of the host chat (the runtime default when the chat has none) and keeps
+ * them; `run` / `answer` with `model` switch the session's model first.
+ * It runs one turn with that Agent's full capabilities (files, shell, Skills, MCP including this
+ * Mini App's own), and resolves when it ends.
+ *
+ * Interaction is yours to render: handle `permission.requested` with `reply` and
+ * `question.requested` with `answer`. A permission request waits only while this run passed
+ * `onEvent` or the session is open in a chat side panel through `open`; otherwise it is denied
+ * and the model is told why. A run with `onEvent` that does not handle the request waits until
+ * `cancel` or the page closes; there is no timeout. Up to `agentConcurrency` runs (default 4) per
+ * Mini App run at once, one per session; further `run` / `answer` calls wait in order (up to four
+ * times that many, see `run.queued`), and `cancel` on a waiting call rejects it with `cancelled`.
+ * `busy` means the session already has a run in progress or the wait queue is full.
+ * Failures reject with an `Error` whose `message` is `invalid_request`, `not_permitted`, `busy`,
+ * `session_not_found`, `runtime_unavailable`, `cancelled`, `result_unknown`, or
+ * `request_not_found`. `runtime_unavailable` means nothing was started; `result_unknown` means
+ * the turn may have run (or ended without the Host knowing whether a question is pending), so
+ * never repeat it automatically.
