Remove the redundant dsh-tui-demo bin and the RESUME_SESSION_ID environment
variable, leaving dsh as the one terminal entrypoint.
The dsh-tui-demo package was a plugin (the TUI app bundle mounted by dsh's
config) plus a bin that booted a leaf cordis.yml — the same job `dsh [config]`
does. The bin, its ./bin export, its built-bin.e2e.ts, the tsdown bin entry,
and the now-unused dsh-app-boot dependency are removed; the package keeps its
plugin and invariant. demo:cordis, demo:code-mode, and the tui-agent and
cordis-agent keyless PTY smokes now launch through apps/cli/src/bin.ts with the
config as the positional argument. cli-demo/acp-demo/jsonrpc-demo keep their
bins (distinct surfaces).
RESUME_SESSION_ID was the only bridge from --resume into the shipped config;
--resume now provides the id on the boot context via ctx.provide(
RESUME_SESSION_ID_KEY, id), and the four configs read it as a bare identifier
through a quoted typeof-guarded !!js expression. The TUI resumeCommand fixtures
and docs move to `dsh --resume {session}`.
Agent Note and its Chinese pair updated; config-catalog regenerated.
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.
