Address the fresh review pass on PR #2798: - ci-workflow.spec.ts: restore the subscription-type assertions the rewrite had dropped (issue-lifecycle pull_request types omit ready_for_review and include review_requested; pull_request_review types == ['submitted']) alongside the new step-level gate checks, so the 'tests pin the subscribed events' gate holds. - 2026-08-10-npm-release-sequences note (en/zh/i18n): the three-sequence table's Workflow column now lists the pack and publish workflows for dsh/vendor, and line 114 no longer claims release.yml publishes (the dsh pack job packs the vendored family for verification; release-publish.yml repacks and publishes). Follow-up for the pack-job copy drift is filed as #2816.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It uses an architecture where everything is a plugin, and is powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Developer preview
DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
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
- Feel free to submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
