Every spec now commits at least one golden and the interactive ones one per distinct end-state (nine new .expected.md): - live-interactions: cancel.expected.md (frozen partial + 已停止 marker), error-auth.expected.md (the prompt bubble alone — the committed artifact of the web-error-surface gap, the diff that flips when error rendering lands), retry.expected.md (indistinguishable from a clean completion — retries are deliberately invisible in the transcript). - question-composer: answered.expected.md (the question resolved into its tool round trip plus the final reply, takeover gone) beside the existing waiting-state golden. - steering: mid-steer.expected.md pins the accepted-but-INVISIBLE state (the loop drains steering only at the step boundary, so no interjection bubble exists while the question still blocks — if the client ever renders pending steers eagerly, this golden flips first) and settled.expected.md the badged bubble plus obeying reply. - navigation-panes: waterfall.expected.md and details-open.expected.md (tool-name header, Input args, Output result) beside the trajectory one. - lifecycle-chrome: reloaded.expected.md — rendering the same settled transcript from persistence alone IS the recovery claim. Fixture inventories extended to the new closed sets; the Agent Note's expected-outputs policy updated in both languages (per-end-state goldens for interactive scenarios), pairing 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.
