Move `docs/defensive-patterns.md` into `docs/defensive-patterns/`, one page per artifact plus a README router, and state each rule as its requirement, the condition a reviewer judges it by, its boundary and approver, and a correct and a wrong example. - `general.md` (the moved page): the existing bug-class rules plus timing, value representation, shared-state ownership, decentralization, performance evidence, and migrations. - `package-surface.md`, `remote-and-api.md`, `client-components.md`, `conversation-and-session.md`: the review requirements for those artifacts, linking type definitions and semantics to `docs/subsystems/` instead of restating them. - `README.md`: the habits behind the rules and the route from artifact to page. - `dsh-code-review` reads the owning pages before judging a diff; the `dsh-architecture-discipline` routing skill is retired in favour of the directory, and every inbound reference is repaired. - Chinese counterparts, pairing records, and the documentation tier table are updated together.
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.
