Add `dsh-host-plugin-manager`: the `pluginManager` service and the `plugins` Remote that install, uninstall, enable, disable, and retry bundles over the booted profile, add and remove rows in the profile's or an agent preset's user layer, report what a package's services keep alive, and fold the manifest, the probe record, and the live tree into one view per package. pnpm runs the way the CLI runs it, streaming its output as `plugins/install-log`; every change emits `plugins/changed`, and api-remotes forwards both. Enabling is the Loader's own transaction: a rejected recomposition restores the layer list, and a runtime recomposition records contained rows through `recordContainedStates` because the boot audit does not run again; `ContainedGroup.create` now records a row that resolved pending rather than clearing it. Give every agent preset a user patch layer: `cordis.patch.yml` beside a locally authored composition, or alone in `.agent-presets/<id>/` for a shipped one. Discovery attaches and judges it, the mount applies it as the include's runtime patches, standing generations follow the layer's content and return to a retired generation when it comes back, the composition inventory reports each row's `source` and `disabledBy`, a copy carries the layer, and `removeOverlay` deletes it. `dsh-global-tool-mask` is `tools.restrict()` as a scope-only row for such a layer. Add `dsh-patch-file` as the one home of the patch-list format: the parser moved out of app-boot, plus a comment-preserving key-level writer with lock, atomic replace, and readback. app-boot exports `layerTrust`, `bundleLayerPatches`, and `recordContainedStates`, and `ProfileRuntime` carries the install anchor.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
Run from source
To run from a repository checkout:
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
