01What can it help you accomplish?
Scaffold a dual-side DeepSeek Harness plugin (host + client) from a working reference
A ready-to-build template that registers a `greet` Remote — the host composes `"Hello, <name>"` and the client renders it in a new "Greet" tab
Plugin developers building for the DeepSeek Harness runtime who want the full plugin surface wired up (type-checking, linting, tests, CI, publishing)
Learn how a DeepSeek Harness host plugin and Web client plugin connect end to end
Annotated `src/` layout, `dsh.plugin.json` registry manifest, `cordis.patch.yml` profile mount, and `build.mjs` dual build
Developers who want a concrete reference for the Harness plugin surface before writing their own plugin
02How to install into DeepSeek Harness
Prerequisites
- Node.js >= 22.19 (or >= 24)
- pnpm >= 9
- DeepSeek Harness >=0.1.0-rc.6
Installation steps
- 01
pnpm install
- 02
pnpm run build
- 03
$ dsh plugin --profile web add .
- 04
Restart the Web Harness after rebuilding the plugin
Verify the integration
- A "Greet" tab appears in the session view ring showing `Hello, DSH`
Rollback
- dsh plugin --profile web remove dsh-plugin-template
03DSH integration and capability boundaries
Built for the DeepSeek Harness runtime: a host plugin exposes a Typert `greet` Remote and a client plugin mounts it into a React view; install via `dsh plugin --profile web add .`.
Host plugin: greet Remote (Typert)
configurable prefix via the Config schema→composes `"Hello, <name>"` string from the prefix and the name
Client plugin: Greet tab (React view)
the greet Remote result→renders `Hello, <name>` in a new "Greet" tab of the session view ring
mounts the Remote into the Web harness module loader and adds a "Greet" tab to the session view ringDual build & CI
TypeScript sources in src/ and tests/→host ESM + client CJS bundles plus type declarations; vitest unit tests; CI on push
04Who is it for? When not to use it?
Good for
- Plugin developers building for the DeepSeek Harness runtime who want the full plugin surface wired up (type-checking, linting, tests, CI, publishing)
- Developers who want a concrete reference for the Harness plugin surface before writing their own plugin
Not for
- A Git install (`dsh plugin --profile web add github:...`) fetches sources, not built artifacts, so pnpm runs `prepare` to build `lib/`. pnpm >=10 blocks that build until you set `allowBuilds`; that allowance lets the package run code at install time, so only allow packages you trust and pin a commit.

06Frequently asked questions
How do I install dsh-plugin-template with DeepSeek Harness?
From a local checkout run `pnpm install`, `pnpm run build`, then `dsh plugin --profile web add .` and restart the Web Harness. A "Greet" tab appears showing `Hello, DSH`.
What are the prerequisites?
Node.js >= 22.19 (or >= 24), pnpm >= 9, and DeepSeek Harness >=0.1.0-rc.6.
How does the template connect to DeepSeek Harness?
It ships a host plugin that exposes a Typert Remote (`greet`) and a client plugin that mounts that Remote into a React view; `package.json` is the only manifest Harness needs, plus `dsh.plugin.json` for the dsh.so registry.
How do I remove it?
Run `dsh plugin --profile web remove dsh-plugin-template`.
Why does a Git install ask me to set allowBuilds?
A Git install fetches sources, not built artifacts, so pnpm runs `prepare` to build `lib/`. pnpm >=10 blocks that until you add `allowBuilds: dsh-plugin-template: true` to the profile's `pnpm-workspace.yaml`; that lets the package run code at install time, so only allow packages you trust and pin a commit.
