dsh-groupx

Bring a local GroupX multi-agent room into DeepSeek Harness.
在 DSH Web 内查看本地 Agent、共享时间线，并向一个或多个 GroupX Agent 显式发送消息。

[!IMPORTANT] This is an independent, unofficial DSH integration for GroupX. The protocol and DSH offline-safety slice is tested; live browser E2E with real GroupX agents remains open.

What works

• Native DSH tab at Settings → Plugins → GroupX.
• Loopback-only Host bridge to GroupX, defaulting to http://127.0.0.1:4310.
• Agent roster, status, recent semantic events, and active Turn summaries.
• Explicit single- or multi-Agent message routing through to[].
• Strict rejection of sender spoofing fields and non-loopback origins.
• Safe DSH startup when GroupX is offline or incompatible.

DSH remains the host and UI. GroupX continues to own native Agent sessions, SQLite, memory, routing, and CLI adapters. The plugin does not bundle GroupX source, upload room data, or rewrite Agent CLI configuration.

Quick start

1. Start GroupX

GroupX 0.1.13 requires Node.js >=24.14.1 <25 and at least one configured local Agent CLI.

npm install --global @susyimes/groupx
groupx start --no-open

2. Build and pack the DSH plugin

git clone https://github.com/Harzva/dsh-groupx.git
cd dsh-groupx
pnpm install --frozen-lockfile
pnpm check
pnpm run pack:dsh

3. Install into the DSH Web profile

dsh plugin --profile web add ./artifacts/harness-flow-dsh-groupx-0.1.0-alpha.0.tgz
dsh web

The dsh plugin --profile <name> add <package> form is provided by the DSH CLI and forwards installation to the selected profile.

For a different GroupX loopback port, set DSH_GROUPX_ORIGIN before starting DSH:

$env:DSH_GROUPX_ORIGIN = 'http://127.0.0.1:5000'
dsh web

LAN, public, HTTPS, credential-bearing, and path-bearing origins are rejected.

Development

pnpm check
pnpm run pack:dsh
pnpm run verify:dsh-offline

verify:dsh-offline creates an isolated temporary DSH Home, installs the packed plugin into a real DSH 0.1.0-rc.6 Web profile, checks the bridge and client module, then removes the temporary profile. It does not read or modify the user's DSH profile.

The local protocol study used upstream commit a6e485f0e3ace6f59324db5fb06f032e3e199b87. At the time of the study, the upstream tree did not declare a license, so its reference copy is excluded from Git and npm artifacts. This repository contains an independent implementation against the documented REST contract.

Architecture and product boundaries are documented in docs/ARCHITECTURE.md, docs/PRD.md, and docs/REFERENCE.md.
