Independent Tasks for DeepSeek Harness

One click creates a timestamped workspace folder and opens a brand-new session inside it — no manual "make a folder, then add it as a workspace, then start a session" dance.

The problem it solves

DeepSeek Harness starts every session in the same workspace unless you first create a folder and register it. Splitting work into independent tasks therefore means repeating the same three manual steps every time.

This plugin adds a single New independent task entry at the very top of the sidebar (immediately under the native "New session" button). Clicking it:

creates YYYY-MM-DD_HHmmss under your chosen root folder,
registers that folder as a Workspace,
creates a session inside it and opens it, and
later renames the Workspace's display title to the session's generated title — while the physical folder name stays the timestamp.

The root folder is chosen from a small dropdown on that same button ([ 📁 │ ▾ ]) and then remembered, so everyday use is a single click.

The native "New session" button is never modified or hijacked.

Install

Requires DeepSeek Harness >= 0.2.2-rc.1.

# From a local checkout
#   then, in the Harness UI: Plugins → install bundle from a directory path,
#   or use the plugin_manager tool with action "install_bundle" and this
#   directory as the target.
git clone https://github.com/skysstst/dsh-independent-task.git

The bundle installs as @local/dsh-independent-task and applies live (application: applied); no restart is needed for the Client half.

Use

Entry point	How
Sidebar button	Click the folder-plus icon at the top of the sidebar (inherits the remembered task folder)
Slash command	Type `/new-independent-task` in a session
HTTP route	`POST /api/dsh-independent-task/create` (loopback + same-origin only)

The sidebar control is a small split button:

[ 📁 │ ▾ ]  New independent task

Click the folder icon (or the row) → creates a timestamped folder and opens a session inside it, under the remembered task folder.
Click the small ▾ → opens the task-folder menu:
- Choose task folder… — opens the native OS folder picker. The picked folder is saved as the remembered root and a new task is created there immediately (one click, no extra step).
- Reset to default — forgets the saved root; new folders go next to the current workspace again.
- The menu header always shows the root currently in use.

The choice is remembered across restarts, so afterwards you normally just click the main button — it keeps using the same folder until you pick another one.

Configuration

Task folder precedence (highest first):

A parentPath sent explicitly with the create request (used by the ▾ menu).
The remembered root saved via the ▾ menu (/api/dsh-independent-task/config, persisted in ~/.dsh/dsh-independent-task.json).
Settings → Independent tasks → parent path (same value, editable as text).
Blank → the new folder is created next to the current workspace.

Relative paths are resolved against the Harness process working directory.

How it works

click / command
      │
      ▼
 resolve parent  ──▶  mkdir YYYY-MM-DD_HHmmss  ──▶  write marker file
      │
      ▼
workspaceRegistry.create(path)  ──▶  sessionController.create({ workspaceId })
      │                                        │
      │                                        └─ Host derives header.cwd from
      │                                           workspace.path and attaches the
      │                                           session itself
      ▼
 client: uiWorkspace.openSession(sessionId)  → conversation opens in one click

The session's header.cwd is set by the Host from workspace.path; this plugin never rewrites it and never renames the directory on disk.
Workspace.path is immutable, so title sync goes through setTitle() — only the display title changes.
Only folders carrying the .dsh-independent-task.json marker are ever renamed, so the plugin cannot touch workspaces you created yourself.

Robustness details

Same-second clicks: instead of appending _2/_3, the plugin waits for the clock to advance and re-stamps, so names stay clean. A 5 s deadline prevents a frozen clock from hanging a request.
Failure rollback: if workspace registration or session creation fails, the fresh folder and any half-registered workspace are removed.
Fast title path: Workspace ids created by this plugin instance are cached in memory, so unrelated session/title events cost no filesystem access.
Trust fence: the HTTP route accepts only loopback sockets with an exact loopback Host, refuses sec-fetch-site: cross-site, and defers to the Host's own connection authority when present.
Clean unload: command, route, listener and timers are all registered through ctx.effect, so disabling the plugin removes everything.

Compatibility

Host and Client halves in one bundle (dsh.bundle.patch + dsh.client).
Client module is a lazy __ModuleLoader__ factory; it needs no build step.
@deepseek-ai/schemastery and @deepseek-ai/cosmokit are vendored under vendor/ (MIT, licenses included) and imported by relative path, so a linked local install resolves them from the plugin's own directory — a linked bundle has no node_modules of its own.
No writes to your profile package.json / cordis.patch.yml; installation goes through plugin_manager.

Troubleshooting

Symptom	Check
Button missing	The sidebar is collapsed to the icon rail — expand it; the row appears under "New session".
Nothing happens on click	Open DevTools console; a failing route returns `403 forbidden` (non-loopback) or `500` with the reason.
Folder created, no conversation	The Client roster frame may be late; the plugin waits up to 3 s, then opens anyway. Report the session id shown in the console.
The ▾ does not respond to keyboard	It lives inside the host's decorative icon slot (mouse-only). Right-click the folder icon also opens the menu, and Settings → Independent tasks → parent path edits the same value.

解决的问题

DeepSeek Harness 默认让所有会话共用同一个工作区；想按任务拆开，就得先建文件夹、再注册成工作区、再新建会话——每次重复三步。

本插件在侧栏最顶部（紧贴原生「新会话」按钮）增加一个「新建独立任务」入口，点一下：

在指定根目录下创建 YYYY-MM-DD_HHmmss 目录；
把该目录注册为 Workspace；
在其中创建会话并直接打开；
会话标题生成后，把该 Workspace 的显示标题同步成会话标题，磁盘目录名始终是时间戳。

根目录通过同一个按钮上的小三角下拉（[ 📁 │ ▾ ]）选择，选完即被记住，日常使用就是点一下。

原生「新建会话」按钮完全不被修改或劫持。

安装

需要 DeepSeek Harness >= 0.2.2-rc.1。

git clone https://github.com/skysstst/dsh-independent-task.git

然后在 Harness 里用「插件 → 从目录安装」，或用 plugin_manager 工具、 action: "install_bundle"、以该目录为 target 安装。bundle 名为 @local/dsh-independent-task，application: applied 即时生效，Client 半无需重启。

使用

入口	方式
侧栏按钮	点击侧栏顶部「文件夹+加号」图标（沿用已记住的任务目录）
斜杠命令	会话里输入 `/new-independent-task`
HTTP 路由	`POST /api/dsh-independent-task/create`（仅限本机回环 + 同源）

侧栏控件是一个小的分离式按钮：

[ 📁 │ ▾ ]  新建独立任务

点文件夹图标（或整行）→ 在已记住的任务目录下创建时间戳目录并打开新会话；
点右侧小三角 ▾ → 打开任务目录菜单：
- 选择任务目录…：呼出系统原生文件夹选择框；选定后立即保存并马上在该目录新建一个独立任务（一步到位）；
- 恢复默认目录：清除记住的目录，回到「当前工作区同级」；
- 菜单顶部始终显示当前正在使用的目录。

选择会被持久记住，重启后依然生效。之后通常直接点主按钮即可，它会继承上一次的设置，直到你再次通过 ▾ 修改。

配置

任务目录优先级（从高到低）：

创建请求里显式携带的 parentPath（▾ 菜单选完目录后就是这条）；
▾ 菜单记住的目录（/api/dsh-independent-task/config，持久化到 ~/.dsh/dsh-independent-task.json）；
设置 → 独立任务 → 父路径（同一个值，可用文本方式编辑）；
留空 → 在当前工作区旁边新建。

相对路径按 Harness 进程的工作目录解析。

实现要点

会话的 header.cwd 由 Host 依据 workspace.path 设置，插件不改写、也不重命名磁盘目录。
Workspace.path 不可变，所以标题同步只走 setTitle()，仅改显示标题。
只重命名带 .dsh-independent-task.json 标记的目录，绝不会影响你自己建的工作区。

健壮性

同一秒连点：不加 _2/_3，而是等到下一秒重新取时间戳，名字始终干净；5 秒上限防止时钟异常导致挂起。
失败回滚：注册工作区或创建会话失败时，自动删除刚建的目录与半注册的工作区。
标题快路径：本实例创建的工作区 id 缓存在内存，其它会话的标题事件不触发任何文件系统访问。
信任围栏：HTTP 路由只接受回环 socket + 精确回环 Host，拒绝 sec-fetch-site: cross-site，存在 Host 连接服务时以其为准。
干净卸载：命令、路由、监听、定时器全部经 ctx.effect 注册，禁用插件即全部回收。

故障排查

现象	排查
看不到按钮	侧栏可能折叠成图标栏，展开后即出现在「新会话」下方。
点击无反应	打开 DevTools 控制台；路由失败会返回 `403 forbidden`（非回环）或 `500` 并附原因。
只有文件夹没会话	Client 名册同步可能延迟；插件最多等 3 秒后仍会尝试打开，可把控制台里的 session id 反馈出来。
小三角按键盘没反应	它位于宿主的装饰性图标槽内，属于鼠标操作；在文件夹图标上右键同样能打开该菜单，也可用「设置 → 独立任务 → 父路径」改同一个值。
