A narrow changes toolbar wrapped its controls onto a second row and the header's buttons broke their labels across two lines. Side by side, a right-side comment was placed with clamp(10px, 100% - 700px, 50% + 10px), so below about 1,420 px it crossed into the left column, and only one comment editor could be open at a time. The toolbar now keeps one line. observeToolbarFold measures what each fold level needs and sets data-fold to the shallowest level that fits: level 1 moves the line totals, expanding all files, two columns, and wrapping into a More view options menu, level 2 the test file switch, with the viewed progress shown as a ring and a count, and level 3 refresh; at level 3 the file list entry shortens its label. The menu lists the controls of the level shown when it opens. Measuring instead of fixed widths keeps every locale on one line: the full toolbar needs about 650 px in Chinese and nearly 800 px in Russian. Header buttons keep their labels on one line. Side by side, the comments that end on a row now sit in a row of two cells under its columns, each continuing its line's gutter and background, so a left and a right comment share the row. Any number of editors can stay open; choosing an open editor's range focuses it. Resolves #8176
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.
