One-click start/stop button pinned to the window bottom-right corner: restarts DeepSeek Harness in place via a detached helper that relaunches the exact boot invocation (loopback same-origin guarded), with an optional stop-only action.
Install
# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)
dsh plugin --profile web add github:huasheng33991/dsh-power-button
Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).

DeepSeek Harness 一键启停按钮 —— 固定在窗口右下角的悬浮电源键。
单击主按钮即可重启 DeepSeek Harness（停旧启新，自动拉起新进程并重连页面）；悬停出现的小按钮可仅停止（不自动重启）。
- 状态点：绿 = 运行中 / 红 = 离线 / 琥珀脉冲 = 重启中
- 重启接口仅接受本机同源请求（拒绝代理转发），伪造来源一律 403
- 持久化安装：本体放
~/.dsh/plugins/dsh-power-button/，通过 profilepackage.json的dsh.profile.bundles自动加载，重启后依然存在
路由
| 路由 | 方法 | 说明 |
|---|---|---|
/dsh-power/health |
GET | 健康检查 { ok: true } |
/dsh-power/restart |
POST | 一键启停：detached helper 等端口释放后按原入口/参数/环境/cwd 重启 |
/dsh-power/stop |
POST | 仅停止，不自动重启 |
安装（profile 层）
# 1. 把本包放入 DSH 用户级插件目录
mkdir -p ~/.dsh/plugins
cp -r dsh-power-button ~/.dsh/plugins/
# 2. 加入 profile 依赖并安装
cd ~/.dsh/profiles/web
pnpm add file:~/.dsh/plugins/dsh-power-button
# 3. 在 package.json 的 dsh.profile.bundles 列表追加 "dsh-power-button"
# （注意：不要再在 cordis.patch.yml 手动 insert，避免 duplicate loader entry id）
# 4. 重启 dsh web 后刷新页面即可看到右下角按钮
卸载
cd ~/.dsh/profiles/web
pnpm remove dsh-power-button
# 并从 package.json 的 dsh.profile.bundles 移除 "dsh-power-button"
技术说明
重启机制：POST /dsh-power/restart 会派发一个 detached node helper，helper 等待 HTTP 端口释放后，用 process.execPath + execArgv + 原始 argv + cwd + 环境变量 重新拉起完全相同的 dsh 启动命令，随后旧进程收到 SIGTERM 优雅退出。新进程脱离原终端独立运行。
踩坑记录：helper 代码中
})换行后紧跟(async必须加前导分号（;(async），否则 ASI 会把 IIFE 吞进上一条语句，helper 静默不执行导致自启失败。

yjh051108/dsh-routing-suite★ 6995
One repository, three parts: a runtime injector for DSH plugin packages (inject, hot-reload, unload, promote a dev staging tool to the front, route self-heal, plus a settings-page plugin manager that lists, unloads and drags folders in to internalize), a task-aware reasoning-mode router agent preset (router-standard / router-spec / router-react), and a graded two-level task protocol whose six tools (commit_star, lock_stage, revise_do, edit_plan, mark_task, redteam_verdict) pin task state to disk. The injector implementation ships in-tree, so the install carries its own behaviour rather than a dependency list.
strukto-ai/mirage#dsh★ 3667
Swaps the filesystem and bash providers for a mirage virtual workspace: file tools and shell commands run over mounted resources (RAM, S3, Redis, Slack, Gmail, Notion, Postgres) instead of the host disk, with per-mount read/write/exec modes, per-command sandbox routing (monty, pyodide, quickjs in process; docker, e2b, daytona remote), and installed CLIs (git, gh, slack, linear, ntn, gws, or one you register) as head words in the virtual terminal.
hust-open-atom-club/oh-dsh★ 325
Community distribution: TUI, desktop, and Web UI as one bundle with layered installation.
weijiafu14/pi2dsh★ 208
Pi Host ABI compatibility engine: after one install, unmodified Pi extensions from npm mount as native DSH plugins with `dsh plugin add <pi-package>`. Verified end to end on stock DSH with pi-mcp-adapter (full MCP manager: OAuth, resources, prompts, MCP Apps, elicitation, sampling), @tintinweb/pi-subagents, pi-code, pi-hermes-memory and pi-background-tasks; `pi2dsh inspect` reports a package's compatibility before installing.
lire1131/dsh-undo-savepoint★ 167
Undo/redo & rollback system for DSH: every config change is auto-snapshotted; undo/redo/restore to any version from the WebUI or the offline CLI/GUI tools (works even when DSH fails to boot).
Fishquito7/dsh-skill-mcp-panel★ 158
Manages DSH skills and MCP servers from the web settings: skill cards with hot enable/disable, workspace scopes, groups, batch migration and drag-and-drop import, plus stdio/HTTP MCP CRUD with connection tests, secret redaction and the unified dsh-panel CLI.
