* ci: run the merge checks on release branches too All three `Policy` workflows filtered on `master`, so a pull request into `release/dsh-*` got no `Master Change` and no `Pre-Merge Check`, and its review check only refreshed when somebody submitted a review. The checks already take their base branch from the event, so the filters now name the release branches as well. * ci: limit the release branch filter to x.y.z `release/dsh-*` also matched prerelease branches such as `release/dsh-0.1.2-alpha.4`; the filter now spells the version digits, so only `release/dsh-x.y.z` counts. * test(snapshot): carry the subagent identity section into the ptc-script-imports scenario The runtime context gained a `subagent:identity` section and every session fixture but this one was regenerated, so replay failed with a mismatch on the added section.

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.
