* feat(experimental): ship the two card experiments as one Personalized recommendations bundle @deepseek-ai/dsh-personalized-recommendations inserts the action card service, its browser half, Personalized pages and Plugin recommendations with their card bodies under the existing row ids. As the only layer that declares those ids, the Plugins page addresses and switches each row, including the two shared card rows that were read-only while two bundles inserted them. The two experiment packages stop being bundles; the new bundle takes their place in the official lists and the dsh installation, with the personalized pages icon, localized title and description, and a feature preview of both cards. The two feature rows describe what they do on the bundle page. * fix(experimental): drop the model reason line from plugin recommendation cards The reason follows the language of the user's question while the catalog description below it follows the interface language, so the two lines could differ in language and largely repeat each other; the answer already gives the reason. The card keeps the catalog title and description, both in the interface language, as its details target. * test(web): refresh the card fixtures for the Personalized recommendations bundle Both card replays enable the new bundle, so each Session lists both card skills, and each skill's catalog lists Personalized recommendations in place of the two former bundles. The plugin card goldens lose the reason line. --------- Co-authored-by: ZiyaZhang <199893125+ZiyaZhang@users.noreply.github.com>
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.
Community and support
- Submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
Contributing
See CONTRIBUTING.md.
Development
Start with the development guide and architecture documentation.
pnpm run dev:web builds, serves, and rebuilds client bundles on source edits in one terminal, and make help lists the matching Make targets for Web and Desktop; the guide's application commands section owns the full table.
For agents, follow AGENTS.md.
