Agent Teams
English | 中文
实验性任务板、模型工具和 host 适配器共享的类型。任务板等待决策负责协调语义；本页记录 packages/experimental/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。
/** 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，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。
/** 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。
/** 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。
/** 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
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 Team 记录。历史成员字段保留在持久化投影状态中，但不发送到浏览器。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。
/** 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[]
}
/**
* 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 tasks: TeamTaskView[]
readonly failure?: string
}
回放
agentTeam 投影按 TeamId 重放历史名册、任务和邮箱记录。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, and the framework-inherited ctx API lives in cordis-api/inherited.md.
