The Windows uninstaller keeps every user file by default and adds a custom page with unchecked options for desktop browser data and update caches, the desktop plugin profile, and the complete Harness home. Selecting the whole home requires a native warning that names the actual folder and the CLI impact, defaults to Cancel, and forces the desktop child selection. Silent and upgrade uninstalls never remove data, including through the legacy --delete-app-data flag, which the adapted upstream template no longer honors. Packaged Desktop records its resolved home in uninstall.ini under the Electron user-data directory so a custom DSH_HOME is offered instead of the default; a length field detects truncated NSIS reads and an invalid record disables whole-home removal. The native remover in window-frame.dll rejects protected roots and overlap with retained data, holds directory handles during traversal, and unlinks reparse points without entering their targets. Installation now also writes InstallLocation on the Windows uninstall entry, which Explorer needs to associate the Start menu shortcut with this entry so that the context-menu Uninstall launches the uninstaller directly instead of opening the installed-apps list. The upstream template only records the value under its private key. Closes #3993
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.
