- forge-github: repeat a compare read without --allow-escape-sequences when a gh older than 2.97 rejects the option; such a gh prints escape sequences unchanged, so every version reads every diff (checked with gh 2.96.0 and 2.100.0 on a pull request whose patch holds an ESC byte). - client-ui-forge: a stale refusal now re-runs the read effect, so a status that arrived during the read, including a failed poll that keeps the earlier head, starts the next read at once instead of leaving the changes view loading. - forge: ctx.forge.diff polls at once only for the first stale read at a head commit; later stale reads at it wait for the regular poll, which bounds the read-poll loop while GitHub's answers briefly disagree. - forge-github: review thread pages share the byte budget of a complete check read. - client-ui-forge: a truncated count shows its "+" even when it is zero. - READMEs: document the batch deadline and rewritten-base limitations.
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.
