Add the browser Settings surface as slot-composed plugins over new preference services: - Rename dsh-client-i18n to dsh-client-locale (locale is the domain name); LocaleService adds getLocale()/setLocale(id), immutable snapshots, a locale/change event, and dsh.locale persistence. - ThemeService owns the light/dark/system preference (default system), resolves system via prefers-color-scheme, publishes theme/change snapshots, persists dsh.theme, and no longer touches the DOM; ui-layout's ThemePresenter applies resolved snapshots (body[data-ds-dark-theme] + alias tokens) and cleans up on dispose. - ui-sidebar drops the phase-1 settings dropdown/modal; the foot renders the new sidebar.settings slot with the column state. - New ui-settings shell occupies sidebar.settings: foot trigger row and the centered 1080x700 panel (figma 501:29947) with 24% mask, close button / mask click / Escape all closing, and a 188px nav projected from the settings.section list slot it declares. Nav labels are registrant-localized; sections re-register on locale change, so the ledger version is the shell's only subscription. - ui-settings-general registers the General section: Permission and Tool Call skeletons, live Language (locale menu) and Appearance (Light/Dark/System cubes following the persisted preference); its slot store mirrors both service snapshots via apply-side listeners. - ui-settings-models registers the Models nav entry with an empty content column. - Portaled menus pin z-index above modal overlays (a menu anchored inside the settings dialog rendered underneath it and was unclickable). - theme/data/list-pen icons in ui-primitives; settings copy ships as zh/en dictionaries; fixture manifests gain the settings rows.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source coding agent built on the DeepSeek Harness SDK.
It uses an architecture where everything is a plugin.
Install
Install dsh with one command:
curl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh
The installer requires git and Node ^22.19 || >=24, offers to install pnpm when it is missing, and prompts for a DeepSeek API key.
The installer clones DeepSeek Harness to ~/.dsh/source, links dsh into ~/.local/bin, and launches it. Re-running the command updates the checkout. See scripts/install.sh for alternate install locations and other options.
Use DeepSeek Harness
Web UI
For the recommended local interface, build the frontend after installation and after each update, then start the Web UI:
pnpm --dir ~/.dsh/source run build && pnpm --dir ~/.dsh/source run build:web
dsh web
The Web UI is served at http://127.0.0.1:3080 by default.
TUI
Start the full-screen terminal interface:
dsh
Headless
Run one task, print the final answer, and exit:
dsh -p "summarize this workspace"
Why DeepSeek Harness
Built-in capabilities cover file reading, editing, and search; shell execution; reusable skills; task tracking; subagents and workflows; persistent sessions; and context compaction. The TUI also includes Plan Mode.
- Everything is a plugin. Models, tools, policies, storage, context management, and interfaces are composable Cordis plugins, so deployments can extend or replace behavior without forking the agent loop. See the architecture for the underlying design.
- Code Mode (opt-in). It exposes a
run_codetool and a generated TypeScript SDK; only program output re-enters model context. See Code Mode. - Self-referential Cordis tools are opt-in. They let the agent inspect its live runtime and mount or unmount plugins while it runs. See the Cordis tools.
