dsh-agent-teams

English · 简体中文

One prompt. A working team.

dsh-agent-teams turns the current DeepSeek Harness session into a captain that can assemble durable sub-agents, split a goal into dependency-aware tasks, and coordinate work through direct messages.

Ask in natural language. The plugin provides the team protocol, 14 coordination tools, persistent state, an automatic shared-task scheduler, and a live Web UI—without requiring a separate workflow engine.

Releases

v0.1.22 targets the published Harness 0.2.0-rc.2 packages and retains script-free Git installation. This plugin release uses npm latest; the recommended host is Harness 0.2.0-rc.2 (its next channel). See the exact support matrix.

Why AgentTeams?

Capability	What it changes
Captain-led delegation	The current session creates the team, assigns roles, and consolidates the final result.
Durable members	Members are continuable DSH sub-agents that can be woken for focused follow-up turns.
Dependency-aware tasks	Tasks move through explicit states and cannot be claimed before their dependencies finish.
Automatic reuse and safe takeover	Idle members claim the next ready task; reassignment revokes stale attempts before new work starts, and cold recovery retries stranded open attempts.
Direct messaging	Members send durable mailbox messages directly to teammates or the captain—no relay required.
Live activity panel	The Web UI combines segmented progress, a collapsible roster, and an interactive task DAG; running tasks show the member's model, and completed archives retain their full member and task history.
Plan before execution	Normal /agent-teams runs stage an unspawned roster and DAG first. The Web panel uses the host model catalog for member routes. Returning to chat stops the planning turn, asks what should change, and revises the same draft; discarding archives the draft, aborts the turn, and explicitly prevents automatic recreation. Only Approve & Run enables scheduling; each member starts with its first ready task.
Quality gates	Opt-in quality tasks support requirements → implementation → verification → review → integration contracts, automatic repair/re-review, and explicit resume. Scope control is a completion-time audit, not host write interception. See docs/quality-gates.md.

The conversation card and activity panel use Harness's official locale service. They follow live language changes between English and Simplified Chinese—including status labels, dynamic summaries, controls, archive markers, and accessibility text—without a page reload or a separate plugin setting.

Install and choose versions

Recommended pair: DeepSeek Harness 0.2.0-rc.2 + AgentTeams 0.1.22. The host remains an RC.

Desktop app

In the app sidebar, open Plugins → Add plugin and enter the npm package spec:

@nanmicoder/dsh-agent-teams@0.1.22

Install it, then choose Enable now. If the host asks for a restart, restart the desktop app. Use the package spec above for the published build; an npm or GitHub webpage URL is not the same install source. For Git installation, use a commit containing the verified build outputs described below.

The desktop app supplies its own Harness core and package manager. Upgrading the global CLI does not upgrade that core, and an ordinary standalone CLI cannot manage its desktop profile. The CLI carrier installed by the desktop app can manage that profile in 0.2.0-rc.2. Check the embedded core against the compatibility list. Harness 0.2.0-rc.2 is now the exact published target; its RC status is unchanged. The earlier source-only 0.2.0 prediction is no longer a support declaration. See the release migration evidence.

CLI / Web: 1. Install DeepSeek Harness

npm install --global @deepseek-ai/dsh@0.2.0-rc.2
dsh --version

Skip this if you already run this version. Alpha is opt-in: select an exact Alpha version from the table and lock all host dependencies as described in the maintenance guide.

CLI / Web: 2. Install the AgentTeams plugin

Install or upgrade from npm (pinned to this latest release):

dsh plugin --profile web add --save-exact @nanmicoder/dsh-agent-teams@0.1.22

For a CLI-managed installation, replace web with your active CLI profile. Stop and restart that profile's Harness process, then refresh the browser. Installing the plugin does not upgrade Harness; the host and plugin have independent latest channels.

For Git installation, use a Git package spec pinned to a commit containing the verified server, client, and type build outputs in lib/, rather than an npm webpage URL. The repository distributes these outputs so installation does not need a prepare hook or build-script approval. Source maintainers must run pnpm build and update the committed outputs whenever the source changes. Existing npm releases remain immutable.

For a manually cloned checkout, run pnpm install --frozen-lockfile and pnpm build after pulling, then restart the corresponding Harness process. Updating Git alone does not update local build output. See the maintenance guide.

For older 0.1.0-* / 0.1.1-* or unlisted hosts, keep a working pair and follow the older-version and diagnostic guide.

See the full compatibility matrix, source installation and Alpha testing guide, and verification coverage and platform limits.

Then ask for a team directly:

Use AgentTeams to review the commits after v0.5.3 from performance, security, and product perspectives. Return one consolidated report.

View teams in the workspace

Click View team in the current chat header or the team card below a reply to open the native Team collaboration tab. The entry belongs to its chat, rather than the general workspace start page.

Team and task content starts immediately: wide panes use columns and narrow panes stack them. Select a task to locate its owner; member icons open their conversations. Closing the tab does not stop the team, and its chat can reopen it. Completed teams retain their archives. Older hosts keep the activity panel.

How it works

1. For a request to use AgentTeams, the captain follows the core protocol already in its system instructions. It continues an existing team and uses agent_teams_status when current state needs checking. When no team exists, the goal becomes a staged plan for review.
2. The captain adds role-specific members backed by continuable sub-agents.
3. The goal becomes tasks with owners and explicit dependencies.
4. The shared scheduler uses real running / idle / ready state to atomically claim one ready task per idle member and wake it. An interrupted resident attempt stays parked and can resume through a direct message without losing its capability; after a cold process restart, the scheduler retries stranded open work with a fresh attempt.
5. Members update with the current attempt_id; reassignment or captain takeover revokes the old attempt and waits for the old worker to quiesce before a new attempt starts.
6. The captain presents the combined result, then archives the complete team record.

Team state is stored under <workspace>/.agent-teams/; the Web panel reads that disk truth and combines it with live sub-agent activity.

Member creation is zero-interaction by default: a member on the captain's current LLM route snapshots that provider, model, and reasoning effort, while a member on a requested alternative route snapshots the target model's default effort; later continuations restore the resolved snapshot. Only an explicit heterogeneous-team request (for example, “backend on provider A/model X, frontend on provider B/model Y”) supplies a member-specific provider + model; there is no per-member model or reasoning prompt.

Captain sessions keep the concise core protocol and the original 14 native team tools from their first request. All business tools are directly available; no loading tool or extra activation call is needed. Configured profiles retain their bounded directory in the fixed system prompt. Creating, approving, continuing or ending a team does not rewrite the system prompt or tool schemas. Core rules remain available after history compaction or discarded code-mode tool results. Members receive four team tools, fixed member instructions, and their ordinary coding/research tools. Web approval wakes the captain with a control message; later member reports wake it again. See the fixed protocol and benchmark contract.

Slash command

No “use AgentTeams” phrasing required. The plugin registers the closed-namespace /agent-teams host command, so the Web GUI slash menu shows an agent-teams placeholder with an input hint: pick it (or type the command), describe the goal, and press Enter.

/agent-teams research the pricing pages of three competitors

The command pipeline claims the line, then preserves that exact input as an ordinary user follow-up so it remains visible in the main chat. The gesture boundary adds the deterministic activation directive at pre-step, so the first model request follows the staged planning protocol without a mandatory helper call. The invocation is also durably logged (command/run / command/done).

Surfaces without command adjudication (for example the headless CLI) get the same deterministic activation through a gesture boundary: any genuine user message starting with /agent-teams activates the protocol for the rest of the text. Mid-sentence mentions stay ordinary prose.

Historical panels require saved team state or archives. Sessions from early versions that deleted teams without retaining archives do not yet support reconstructing the full panel from logs.

Configuration

Defaults work without extra setup. A trusted profile can override member behavior:

- id: agent-teams
  config:
    stateDir: .agent-teams
    memberProvider: spawn
    memberModel: deepseek-v4
    memberMaxDepth: 0
    maxMembers: 8

memberMaxDepth defaults to 0: team members cannot create nested subagents. Set 1 to explicitly permit one descendant level; the limit also covers runtime/code-tool calls. Default members report through team messages only, avoiding duplicate native parent reports. Idle roster members make no model requests. Task assignments start distinct turns; coordination joins the nearest model step. Acceptance and consumption are tracked separately. Removal/archive drains the selected branch and its pending input before reporting success.

memberProvider is the sub-agent runtime backend (spawn / fork), not an LLM provider. Cross-LLM-provider routing uses the optional provider + model fields of agent_teams_add_member; memberModel is only a model default for all members. A member on the captain's current provider/model inherits the captain's reasoning effort, while a changed provider or model automatically uses the target model's default. To request a particular effort, pass the optional reasoning_effort field — one of the target model's supported effort ids, or "default" to force the model's own default.

slashCommand: false disables the deterministic /agent-teams activation surfaces (slash command and gesture boundary), leaving the natural-language trigger as the only entry point.

Boundaries

• One captain leads one active team at a time.
• Idle members with no open task are automatically reused for ready work. An idle member that still owns an open attempt is parked until messaged or explicitly reassigned; messages that cannot be delivered live remain durable and are retried at a later status boundary.
• State is file-backed and serialized within one DSH process; concurrent processes editing the same team are not coordinated.
• The activity panel reports persisted state as-is. Models may occasionally finish work without performing the expected task-state update.

See docs/usage.md for the full tool reference, state model, Web UI behavior, configuration, and known limits.

Named multi-role profiles

Configure one or more complete team profiles in cordis.patch.yml. A profile always supplies the roster (independent provider/model/role/reasoning effort). Set taskPlanning: captain when the Captain should derive the DAG from the user's goal; omit it or set taskPlanning: seed to keep a fixed template workflow:

profiles:
  demo-delivery:
    description: Ship a small feature
    protocol: Discuss requirements, review, test, then prepare release; do not deploy automatically.
    members:
      - name: analyst
        model: gpt-5.6-sol
        role: Analyze requirements
      - name: implementer
        model: gpt-5.6-terra
        role: Implement the approved solution
    tasks:
      - id: requirements
        subject: Requirements discussion
        assignee: analyst
      - id: implementation
        subject: Implement solution
        assignee: implementer
        dependencies: [requirements]

Use an explicit profile flag: /agent-teams --profile demo-delivery implement the feature. The first ordinary token is never treated as an implicit profile. Normal command runs call agent_teams_create({ profile, approval: "required" }): the roster and seed/Captain-designed DAG remain staged, no child session is created, and no task is claimed. Edit the plan in the activity panel using the host model catalog, return to chat so the Captain asks what to revise and then atomically updates the same draft, discard it, or click Approve & Run. Return/discard actions cancel any planning turn still running; discard also parks model-facing context that forbids silently creating a replacement team. Approval resolves the final provider/model/reasoning choices, commits the roster, and creates each member session only when its first task is ready. A running team is stopped from its own panel header through a confirmation dialog rather than from the composer. Direct tool clients may pass approval: "automatic" for the legacy immediate path. Failed review/test tasks do not unlock downstream work; automatic repair/review tasks do not depend on the failed review.
