DeepSeek Harness Agent Team

English | 简体中文

dsh-agent-team gives DeepSeek Harness a persistent agent team for long-running collaboration: agents are durable identities for their sessions, keeping memory and responsibilities across them; Workspaces organize agents and sessions per project; Channels carry responsibilities; Task Threads chain session agents into one line of progress.

An opt-in plugin for DeepSeek Harness: install it only where Team mode is needed; ordinary DSH sessions keep their normal preset roster.

Core ideas

• Agents are first-class team members, not just sessions. Each member keeps its own memory, responsibility boundaries, and private space (memory, notes, and skills), while all agents collaborate in one shared project Workspace; multiple Workspaces manage multiple teams.
• Workspaces organize everything. Different projects live in different Workspaces, each managing its own Agents and Channels.
• The Human routes Channels and responsibilities. You decide who is in which channel and what they own; mentions route work to the right agent.
• Task Threads carry one line of progress. Claims set the direction, Threads hold the context, and multiple session agents advance the same line of work without talking past each other — the facts of the work live in one Thread.
• No context babysitting. Members manage their own context: roll over to a fresh one and stay on duty (context_rollover), or return to a past anchor (context_timeline / context_checkpoint); pending work survives switches and restarts, and memory and notes keep accumulating — a member carries its full memory into every new context.

Preview

Agent Team is opt-in: after installation the ordinary DSH page stays as-is, and Team mode is one additional entry in the sidebar footer.

Entering Team mode shows Channels, managed Agents, and the collaboration timeline:

Task Threads

A Task Thread keeps Claims, Agent handoffs, Human acceptance, and follow-up replies in one durable context.

If this looks useful, a star on GitHub helps other DSH users find it.

Quick start

1. Check DSH

This release is certified against DSH 0.1.2-rc.1. If dsh is not installed yet, start DSH with the official package:

npx @deepseek-ai/dsh web

Stop it, then install Agent Team into the web profile:

dsh plugin --profile web add @wowyuarm/dsh-agent-team

2. Start the Web UI

dsh web

Agent Team is opt-in. Installing it adds the bundle to the web profile; it does not modify the Harness installation or shipped defaults.

3. Verify and try it

Before starting the UI, you can inspect the composed profile:

dsh --profile web --dump-config

The output should include Team rows such as wowyuarm-agent-team-scope and wowyuarm-agent-team-client. In the browser, enter Team mode from the DSH navigation. The first useful path is:

Team mode
└── select a Workspace
    ├── Channels -> New Channel -> send the first message
    └── Agents   -> Add Agent -> choose its initial Channels

Create an Agent only in a trusted Workspace. The Team Member preset intentionally grants managed Agent Sessions danger-full-access.

Uninstall

Remove the bundle from the profile; this also removes its composed layers:

dsh plugin --profile web remove @wowyuarm/dsh-agent-team

What it adds

• A durable single-host Team with Channels, Messages, Tasks, Threads, Claims, and Agent membership.
• A Web Client for Human control: create Channels and Agents, manage membership, send Messages, open Threads, and handle Tasks.
• An isolated team-member preset with five model-facing tools: team_inbox, team_thread, team_message, team_claim, and team_view.
• A pull-based collaboration protocol. Agent Inbox admission is durable, but it does not claim that the model has already processed the update.

The Team is one collaboration domain per DSH home. Its append-only operation ledger is the authority; UI, Remote responses, tools, Inbox, and other projections derive from committed operations. Ordinary DSH Sessions keep the profile's normal preset roster and do not receive Team tools or guidance.

Install from a local checkout

For development, install the local bundle into the same profile:

dsh plugin --profile web add /absolute/path/to/dsh-agent-team
dsh web

Published packages include built artifacts. A local checkout needs the adjacent Harness repository only for development checks, not for end-user installation.

Development

Read docs/README.md for the maintained documentation index. The usual checks are:

corepack pnpm install
npm run typecheck
npm test
npm run build
npm run lint
npm run test:browser
npm pack --dry-run

npm run test:browser uses the adjacent ../deepseek-harness checkout, an isolated temporary profile, and /usr/bin/google-chrome (override with CHROME_PATH). It does not need provider credentials. For manual checks, npm run preview:ui loads Team fixtures without model streaming; DEEPSEEK_API_KEY=... npm run preview starts the real provider preview. Both preview commands clean up their temporary state on Ctrl+C.

Architecture and the collaboration contract are documented in docs/architecture.md and docs/team-collaboration.md.

Acknowledgments

The collaboration shape of dsh-agent-team — named agent members, Channels, Task Threads, @mention routing, and per-member memory — originates from and borrows several design ideas from Raft. Thank you for the work.
