Two new keyless scenarios for the functionality master gained since this lane's base (#644 websettings, #643 workspace browser rework), both zero model calls: - settings-chrome: the modal shell (sidebar-foot trigger aria states, role=dialog, aria-current section switch to the deliberately empty Models, Escape + close-button paths, dialog aria golden); the Appearance row as the REAL theme gesture — retiring lifecycle-chrome's TODO(web-theme-gesture): clicking 深色 runs aria-pressed -> persisted dsh.theme -> body[data-ds-dark-theme] -> alias-token flip, survives reload, and 'system' follows the emulated OS scheme both ways; the Language row switches the settings-scoped copy to English (dsh.locale persisted, survives reload) and restores zh. Intentional reloads tear the SSE stream, so the spec drains exactly its own reconnect warnings — the tripwire still fails on unexpected connection loss. - workspace-management: create-by-name twice through the region-header dialog (host-durable via ctx.workspace.list()); rename end to end — hover-revealed row menu (the button is display:none until the row hovers), duplicate-name pre-check (inline role=alert + disabled primary before any wire call), then workspace.rename through the real RPC, row update, host durability, reload survival; the flat 'In one list' view (section label flips, group headers drop, dsh.workspace.view persists across reload, grouped restored); the session hover card (dwell to open, closes on pointer leave). The one session row reuses seeded-history's committed seed — no new recording. Deliberately not driven: the inert menu rows and drag reorder (deferred in the note with re-entry triggers). Agent Note gains scenarios 8-9 and the drag-reorder deferred item in both languages; llm-replay README's zh side catches up with the { patches } paragraph; pairings re-recorded.
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.
