Add a startup-only sdk-minimal template whose sole bundle inserts the complete JSON-RPC agent tree over the empty profile root. The roster is an explicit composition allowlist: it contains one DeepSeek adapter, the minimal agent spine, persistent Bash, the string-replace editor, local execution, and JSONL persistence, while dsh-base and Web remain absent. Reuse the SDK app startup provider so the new profile retains help, stdin EOF, and bounded launcher shutdown semantics. Make that provider render its configured profile name, which keeps both sdk and sdk-minimal help truthful without duplicating process lifecycle code. Register the package in the CLI closure, TypeScript graph, lockfile, Knip policy, and bilingual bundle references. Exact manifest, row-roster, profile-template, config-dump, and HMR tests make later additions visible instead of relying on a blacklist.
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.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is currently in developer preview and is 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
- 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.
