master 通过 #7700 将 portal 菜单改为 CSS Anchor Positioning，并删除了 `useAnchoredPosition`。本次合并让子菜单跟进同一机制： - 子卡片以父卡片内一个不随列表滚动、与卡片同尺寸的锚点框为默认锚点， 侧开时默认在右侧、放不下时由 CSS 翻到左侧；单面板模式占据父卡片位置。 - JavaScript 只决定侧开或单面板，并提供当前行在父卡片内的偏移和子卡片 自然高度；两者都是相对尺寸，双指缩放与平移由 CSS 锚点处理。 - 锚点框绕开了 WebKit 的两个问题：锚定到自身由锚点定位的父卡片时不会 在其定位稳定后重新计算；锚定到滚动列表内的行时不计入滚动偏移。 - 删除 `useAnchoredPosition` 及其测试；`menu-submenu-position` 只保留 侧开/单面板判断，相应单测改为验证模式与锚点名。 - 解决 README、测试与 package.json 冲突，沿用 master 的 CSS 锚点说明并 补充子菜单定位描述。
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.
