# Agent Teams
|
||
|
||
[English](agent-team.md) | 中文
|
||
|
||
共享任务板、模型工具和 host 适配器共享的类型。[任务板等待决策](../../.agents/notes/implemented/architecture/2026-10-19-team-task-board-inbox.zh.md)负责协调语义；本页记录 [`packages/team/agent-team/src/types.ts`](../../packages/team/agent-team/src/types.ts) 中的持久化和客户端可见形式。
|
||
|
||
## 身份与历史名册
|
||
|
||
`TeamId` 品牌化根 `SessionId`；`TeamTaskId` 使用 `task-<n>`。`TeamMessageId` 和名册记录为历史解码保留。subagent 运行时解析树，并发现任意深度的有效任务所有者；历史名册条目不授予权限。
|
||
|
||
```ts type-equiv
|
||
/** Historical roster value written by earlier Team builds on every teammate lifecycle change. */
|
||
interface TeamMemberSnapshot {
|
||
readonly id: SessionId
|
||
readonly name: string
|
||
readonly description: string
|
||
readonly provider: string
|
||
readonly context: 'fresh' | 'fork'
|
||
readonly phase: TeamMemberPhase
|
||
readonly error?: string
|
||
}
|
||
```
|
||
|
||
历史记录保留其记录的 `provisioning`、`active` 或 `failed` 阶段。当前轮次活动属于普通 subagent 发现和 Session 状态，与任务完成相互独立。
|
||
|
||
## 消息与历史 mailbox
|
||
|
||
成员交换普通 [subagent 消息](subagent.zh.md)，保留真实发送方 Session id。任务提交刷盘后，向同树所有驻留 Agent（包括调用者和根）的当前等待发出信号。这些内存信号不持久化未读状态，不恢复冷成员，也不启动空闲轮次。不在等待期间发生的变更不能唤醒后续等待。下列历史邮箱类型保持可读；Team 绝不投递其待处理记录。
|
||
|
||
```ts type-equiv
|
||
/** One peer message recorded by the historical Team mailbox. */
|
||
interface TeamMessageSnapshot {
|
||
readonly id: TeamMessageId
|
||
readonly senderId: SessionId
|
||
readonly senderName: string
|
||
readonly targetId: SessionId
|
||
readonly content: ContentBlock[]
|
||
}
|
||
```
|
||
|
||
历史 `team-message` source 保留旧消息 id 与发送者归属；客户端用它们展示消息标题和图标。
|
||
|
||
```ts type-equiv
|
||
/** Source recorded by a target Session for one historical Team mailbox delivery. */
|
||
interface TeamMessageSource {
|
||
readonly kind: 'team-message'
|
||
readonly teamId: TeamId
|
||
readonly messageId: TeamMessageId
|
||
readonly senderId: SessionId
|
||
readonly senderName: string
|
||
}
|
||
```
|
||
|
||
## 共享任务 DAG
|
||
|
||
每条 task event 都存储完整快照。`revision` 是 compare-and-set 值，每次变更递增 1。`blockedBy` edge 必须指向未删除任务，并维持无环图。`writeScopes` 是规范化的提示性路径前缀，不是锁。
|
||
|
||
```ts type-equiv
|
||
/** Whole durable task snapshot; every mutation increments {@link revision}. */
|
||
interface TeamTaskSnapshot {
|
||
readonly id: TeamTaskId
|
||
readonly revision: number
|
||
readonly subject: string
|
||
readonly description: string
|
||
readonly status: TeamTaskStatus
|
||
readonly ownerId?: SessionId
|
||
readonly blockedBy: TeamTaskId[]
|
||
readonly writeScopes: string[]
|
||
}
|
||
```
|
||
|
||
`pending` 表示未开始或已释放，`in_progress` 携带负责人，`completed` 满足依赖，`deleted` 是保留的墓碑记录。视图提供 `ownerId`、就绪性和写入范围重叠提示，不改变持久快照。

||

|
||
|
||
## Web 投影
|
||
|
||
`agentTeam.enabled` 提供根 Session 保存的选择。新 Session 默认为 false；`team/mode` 记录显式选择。历史任务在显式选择前视为开启。仅根可调用 `setEnabled`；后代共享该模式。Web 菜单通过 `remote.agentTeams.setEnabled` 调用同一方法，Gateway 将根 Session id 解析为其存活 Agent。模式写入先立即生效，再等待刷盘。工具在步骤准备时确定可用性；提示词提供方在求值时读取选择。任务修改在排队操作开始时检查当前模式；已获准的修改可继续完成。模式变更不会结束收件箱等待。刷盘失败时已追加的选择仍然生效；重试相同选择会再次刷盘，不重复追加事件。
|
||
|
||
根 Session 通过 `SessionProjectionMap.agentTeam` 发布未删除任务视图。`failure` 在最后有效状态旁报告被拒绝的持久化任务或模式记录。历史名册与邮箱记录不参与投影。任务面板将根标记为主代理，其他负责人依次使用目录标签、Session 标题或 id。
|
||
|
||
```ts type-equiv
|
||
/** Runtime-enriched task view returned to tools and hosts. */
|
||
interface TeamTaskView {
|
||
readonly id: TeamTaskId
|
||
readonly revision: number
|
||
readonly subject: string
|
||
readonly description: string
|
||
readonly status: TeamTaskStatus
|
||
readonly blockedBy: TeamTaskId[]
|
||
readonly writeScopes: string[]
|
||
readonly ownerId?: SessionId
|
||
readonly ready: boolean
|
||
readonly writeScopeWarnings: string[]
|
||
}
|
||
```
|
||
|
||
```ts type-equiv
|
||
/**
|
||
* Durable Team state published to browser clients through the Lead Session's
|
||
* `agentTeam` projection. `failure` names the first rejected persisted Team
|
||
* record; tasks then stay at the last valid state.
|
||
*/
|
||
interface TeamProjection {
|
||
readonly enabled: boolean
|
||
readonly tasks: TeamTaskView[]
|
||
readonly failure?: string
|
||
}
|
||
```
|
||
|
||
## 回放
|
||
|
||
`agentTeam` 投影按 `TeamId` 重放任务记录，并重放 Session 自身的模式选择。subagent 发现负责当前树成员关系，不将继承目录作为权限来源。Session 事件的 `seq` 和 `time` 负责排序和时间。已提交的持久化代次保持不变。[包 README](../../packages/team/agent-team/README.zh.md)定义任务操作和限制。

## Cordis API
|
||
|
||
Generated from source by `scripts/gen-cordis-catalog.ts` (verified fresh by `pnpm run verify-cordis-catalog` in doc-sync; regenerate with `pnpm run gen-cordis-catalog`) — the language sides differ only in locale-specific paired document paths. Signature blocks use a `ts cordis-catalog` fence and keep the original source JSDoc; dispatch modes are defined in the [primer](../cordis-primer.zh.md#dispatch-modes), and the framework-inherited `ctx` API lives in [cordis-api/inherited.md](../cordis-api/inherited.md).
