Add the Manage plugins tab (ui-settings-plugin-manager): package cards
with enable/disable switches, retry and uninstall, an install dialog
streaming pnpm output, and the selected preset's composition with per-row
switches and removal; the read-only list gains provenance facts.
Settings cards edit one scope at a time: ui-settings keeps one describe
mirror per settings scope (SettingsMirrorRegistry) and binds
{ namespace, scope }; ui-settings-plugins stages forms per scope, marks
inherited fields, and adds the skill-filesystem roots card.
Fixes surfaced by driving the browser end to end: the client gateway now
lets a call omit trailing parameters that accept undefined (PR3's
optional scope arguments failed the strict arity check), the plugins
install verb is `add` because the client namespace service reserves
`install`/`remove` (guarded by remote-method-names.host.spec), a plugin
module offers its main export as an addable `.`, and describing a settings
scope no owner registered resolves over the global instance's base and
never throws.
The web e2e scaffold can mount a profile runtime over fixture packages;
plugin-manager.e2e drives the tab and writes one field under a preset
scope; plugin-config and settings-chrome goldens are refreshed.
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.
