imccyu fb47f61a83 refactor(gui): host graph from dshClient discovery; webserver self-watches bundles for HMR
The registry scans mounted Loader entries' dshClient declarations and
composes __DSH_BOOT__ {rev, entries} — inject edges and the immediately
mark come from manifests, never hand-copied; malformed fields fail loud
at load. The composing app owns one flat roster plus the --dev switch
(hmr row and bundle watching are dev-graph decisions).

The rebuild signal is the webserver's own observation: in dev mode the
registry stat-polls each scanned bundle (fs.watchFile; polling because
network mounts deliver no inotify), re-hashes on change, and broadcasts
a rebuilt frame on the /plugins/events SSE channel only when the rev
actually changed. Watch membership follows the table across rescans;
dispose drops all watches; a torn read self-heals on the next tick.
The POST /plugins/rebuilt endpoint is gone — builders and the host
share zero protocol. dsh web --dev logs the watched bundle list and
each rebuilt id with its rev transition.

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_code tool 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.
