A settings namespace is now a kind; each registration is an instance
filed under the caller's nearest named scope (dsh-scope gains
createScope(..., { id }) and scopeIdOf). Instances resolve defaults →
composition base → global user section → scopes.<id>.<ns>. Global writes
fan out to every instance gated on its own resolved value; scoped writes
commit one instance. Revisions are per section so a scope nothing has
registered yet can still be written when the kind exists. describe(),
the controller verbs, and both events take an optional trailing scope.
Presets name their standing scopes preset/<id>; skill-filesystem is the
first consumer, resolving customSkillDirs per scope with live updates.
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.
