dsh-plugin-hot-toggle

Hot-toggle any installed plugin from the DeepSeek Harness Web settings page (Plugins → 启停管理): stop or start a Cordis Loader entry in-process with instant effect and no DSH restart — the state persists across restarts.

中文文档 | English

Features

• Hot toggle: calls the official Cordis Loader Entry.update({ disabled }) — disabling disposes the plugin fiber, enabling re-imports and starts it, all in-process with instant effect. No DSH restart needed.
• Persistent: the toggle state is written to the profile patch layer ($DSH_HOME/profiles/<profile>/cordis.patch.yml) and hot-applied by the official HMR watcher on save — survives restarts.
• Safety guard: system-core entries (include, cordis:*, loader/hmr/timer, the dynamic-plugin host) cannot be toggled and are marked 「系统核心」.
• Multi-dimensional filters (combinable):
  • State: all / enabled / disabled
  • Source: all / official / core / community (community = a matching directory under $DSH_HOME/plugins)
  • Type: builtin framework / client UI / LLM / tools / session & storage / sandbox & exec / agent & planning / services & integration / other
  • Search + live count (filtered / total)
• Sorting: recent-first (community plugins ahead) or by name.

Installation

From a local checkout (development)

dsh plugin --profile web add ./dsh-plugin-hot-toggle

From npm (after publish)

dsh plugin --profile web add dsh-plugin-hot-toggle

From git (after publish)

dsh plugin --profile web add github:5102a/dsh-plugin-hot-toggle

After installation, start DSH (or let HMR apply it) and open Settings → Plugins → 启停管理.

Platform support

The plugin runs on Windows, macOS, and Linux — the three platforms DeepSeek Harness itself supports.

Concern	Guarantee
Host half	All filesystem paths go through node:path (join/dirname) and fileURLToPath; no hardcoded separators
Persistence	Patch-layer writes use readFileSync/writeFileSync(…, 'utf8') with paths derived from the Loader include
HTTP API	/plugin-hot-toggle/api/* is a URL route — platform-independent
Client half	Pure browser fetch + React; no process.platform/navigator.platform branches
Build	scripts/build.mjs resolves paths from import.meta.url via fileURLToPath + join
Dev tooling	Chrome/Edge discovery honors CHROME_PATH/CHROME_BIN or a cross-platform candidate list; DSH_URL overrides the target origin
CI	GitHub Actions matrix: ubuntu + windows + macos × Node 18/20/22

• Node half uses only public seams (loader, webServer, dshHomePath) — zero DSH core changes. webServer is injected dynamically, so TUI/headless surfaces never pend.
• Web half talks to the Node half over a same-origin HTTP API; mutating requests carry a same-origin check (missing Origin / cross-origin → 403).
• Client bundle is generated from src/client.js by a zero-dependency build script (node scripts/build.mjs) and committed to the repo, so git/npm installs need no build step.

API

Method	Path	Body	Returns
GET	/plugin-hot-toggle/api/list	—	{ entries: PluginEntry[] }
POST	/plugin-hot-toggle/api/setEnabled	{ entryId, enabled }	SetEnabledResponse

See index.d.ts for PluginEntry / SetEnabledResponse.

Development

npm run build   # generate lib/client.js from src/client.js
npm test        # node:test unit tests
npm run check   # build + test in one step

Publishing

npm run check && npm run build
npm publish

The name dsh-plugin-hot-toggle was verified available with npm view before release.

Note on peer-dependency warnings: the package declares @deepseek-ai/cordis and react as peer dependencies (the same pattern as the official @deepseek-ai/* plugins). DSH resolves them from its own installation via the profile's flat fallback, so an "unmet peer" warning during dsh plugin add is expected and harmless.
