@terricsh/dsh-app-launcher

Workspace launcher for the DeepSeek Harness Web GUI.

Adds a split control to the session header's right-aligned utilities row
(beside session export):

• 主按钮「打开」：以文件夹形式打开当前工作区（资源管理器）。
• 「命令行」：在当前工作区目录打开一个 cmd 窗口（cmd /k，窗口保持），
  方便直接执行命令。
• 右侧「▾」下拉：切换用其他工具打开工作区，如 VS Code（code）、
  opencode、Cursor——仅显示本机实际安装的工具；也可在「管理工具…」中
  自行添加/删除（名称 + 命令，支持可执行文件名或完整路径）。
• 菜单与按钮显示 Windows 系统图标（文件夹图标取自 shell32.dll；
  工具图标从其真实 exe 提取）。

Installation

Add the plugin row to the host patch layer (e.g.
$DSH_HOME/profiles/<profile>/cordis.patch.yml):

- insert:
    - id: app-launcher
      name: '@terricsh/dsh-app-launcher'

Install the package where the profile can resolve it (the profile's
node_modules, e.g. via a junction to a local checkout), then restart the
dsh web server.

How it works

• Host half (lib/index.js) registers three HTTP routes:
  • POST /dsh-launcher/launch — { kind: 'folder', path } opens the folder
    in Explorer; { kind: 'terminal', path } opens a persistent cmd /k
    window at the path; { kind: 'tool', command, path } resolves the real
    .exe (skipping .cmd/.bat shims so no extra console window appears)
    and starts it with Start-Process <exe> "<path>" (falling back to the raw
    command for terminal tools such as opencode).
  • POST /dsh-launcher/check — probes where.exe for a command.
  • POST /dsh-launcher/icon — extracts the folder icon from shell32.dll
    or a tool's associated icon and returns it as a PNG data URL (cached).
• Client half (lib/client.js) renders the split launcher into
  conversation.session.header.utilities, derives the current workspace from
  the session/workspace snapshots, and calls the routes with fetch.

Launching is an explicit desktop action, so the host executes it with the
danger-full-access sandbox policy (the deployment default workspace-write
has no usable Windows ACL runner on this host).

Windows only. Requires the shell and sandboxPolicy services (shipped with
the default web profile).
