The install dialog asks the Host to read a spec before installing it: `plugins/inspect` sorts the spec (registry name, absolute path, git address, tarball), asks the registry through `pnpm view` in the profile directory, or reads a directory's package.json, and refuses what would fail with `plugins/inspect-rejected` and a problem the dialog words under the field. A failed pnpm run carries a `kind` classified from how it ended and what pnpm printed, shown as one line with the output folded behind the details. Enabling happens after the fact from the installed screen, which scrolls the list to the first new bundle. Refusals of the moment and the confirmed cancellation are toasts; the run is stopped through the manager's `cancelInstall` and the dialog offers the spec again once the Host confirms. The non-pack dependency group folds by default under its own name. The host config gains `inspectTimeoutMs`; the CLI passes it explicitly.
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.
