Team Lifecycle

Team Lifecycle

Unified team skill covering specification, implementation, testing, and review. All team members invoke this skill with --role=xxx to route to role-specific execution.

Role Router

Input Parsing

Parse $ARGUMENTS to extract --role:

const args = "$ARGUMENTS"
const roleMatch = args.match(/--role[=\s]+(\w+)/)

if (!roleMatch) {
  throw new Error("Missing --role argument. Available roles: coordinator, analyst, writer, discussant, planner, executor, tester, reviewer")
}

const role = roleMatch[1]
const teamName = args.match(/--team[=\s]+([\w-]+)/)?.[1] || "lifecycle"

Role Dispatch

const VALID_ROLES = {
  "coordinator": { file: "roles/coordinator.md", prefix: null },
  "analyst":     { file: "roles/analyst.md",     prefix: "RESEARCH" },
  "writer":      { file: "roles/writer.md",      prefix: "DRAFT" },
  "discussant":  { file: "roles/discussant.md",  prefix: "DISCUSS" },
  "planner":     { file: "roles/planner.md",     prefix: "PLAN" },
  "executor":    { file: "roles/executor.md",    prefix: "IMPL" },
  "tester":      { file: "roles/tester.md",      prefix: "TEST" },
  "reviewer":    { file: "roles/reviewer.md",    prefix: ["REVIEW", "QUALITY"] }
}

if (!VALID_ROLES[role]) {
  throw new Error(`Unknown role: ${role}. Available: ${Object.keys(VALID_ROLES).join(', ')}`)
}

// Read and execute role-specific logic
Read(VALID_ROLES[role].file)
// → Execute the 5-phase process defined in that file

Available Roles

Shared Infrastructure

Message Bus (All Roles)

Every SendMessage before, must call mcp__ccw-tools__team_msg to log:

mcp__ccw-tools__team_msg({
  operation: "log",
  team: teamName,
  from: role,
  to: "coordinator",
  type: "<type>",
  summary: "<summary>",
  ref: "<file_path>"
})

Message types by role:

CLI Fallback

When mcp__ccw-tools__team_msg MCP is unavailable:

Bash(`ccw team log --team "${teamName}" --from "${role}" --to "coordinator" --type "<type>" --summary "<summary>" --json`)
Bash(`ccw team list --team "${teamName}" --last 10 --json`)
Bash(`ccw team status --team "${teamName}" --json`)

Task Lifecycle (All Worker Roles)

// Standard task lifecycle every worker role follows
// Phase 1: Discovery
const tasks = TaskList()
const prefixes = Array.isArray(VALID_ROLES[role].prefix) ? VALID_ROLES[role].prefix : [VALID_ROLES[role].prefix]
const myTasks = tasks.filter(t =>
  prefixes.some(p => t.subject.startsWith(`${p}-`)) &&
  t.owner === role &&
  t.status === 'pending' &&
  t.blockedBy.length === 0
)
if (myTasks.length === 0) return // idle
const task = TaskGet({ taskId: myTasks[0].id })
TaskUpdate({ taskId: task.id, status: 'in_progress' })

// Phase 1.5: Resume Artifact Check (防止重复产出)
// 当 session 从暂停恢复时，coordinator 已将 in_progress 任务重置为 pending。
// Worker 在开始工作前，必须检查该任务的输出产物是否已存在。
// 如果产物已存在且内容完整：
//   → 直接跳到 Phase 5 报告完成（避免覆盖上次成果）
// 如果产物存在但不完整（如文件为空或缺少关键 section）：
//   → 正常执行 Phase 2-4（基于已有产物继续，而非从头开始）
// 如果产物不存在：
//   → 正常执行 Phase 2-4
//
// 每个 role 检查自己的输出路径:
//   analyst  → sessionFolder/spec/discovery-context.json
//   writer   → sessionFolder/spec/{product-brief.md | requirements/ | architecture/ | epics/}
//   discussant → sessionFolder/discussions/discuss-NNN-*.md
//   planner  → sessionFolder/plan/plan.json
//   executor → git diff (已提交的代码变更)
//   tester   → test pass rate
//   reviewer → sessionFolder/spec/readiness-report.md (quality) 或 review findings (code)

// Phase 2-4: Role-specific (see roles/{role}.md)

// Phase 5: Report + Loop
mcp__ccw-tools__team_msg({ operation: "log", team: teamName, from: role, to: "coordinator", type: "...", summary: "..." })
SendMessage({ type: "message", recipient: "coordinator", content: "...", summary: "..." })
TaskUpdate({ taskId: task.id, status: 'completed' })
// Check for next task → back to Phase 1

Three-Mode Pipeline

Spec-only:
  RESEARCH-001 → DISCUSS-001 → DRAFT-001 → DISCUSS-002
  → DRAFT-002 → DISCUSS-003 → DRAFT-003 → DISCUSS-004
  → DRAFT-004 → DISCUSS-005 → QUALITY-001 → DISCUSS-006

Impl-only:
  PLAN-001 → IMPL-001 → TEST-001 + REVIEW-001

Full-lifecycle:
  [Spec pipeline] → PLAN-001(blockedBy: DISCUSS-006) → IMPL-001 → TEST-001 + REVIEW-001

Unified Session Directory

All session artifacts are stored under a single session folder:

.workflow/.team/TLS-{slug}-{YYYY-MM-DD}/
├── team-session.json           # Session state (status, progress, completed_tasks)
├── spec/                       # Spec artifacts (analyst, writer, reviewer output)
│   ├── spec-config.json
│   ├── discovery-context.json
│   ├── product-brief.md
│   ├── requirements/           # _index.md + REQ-*.md + NFR-*.md
│   ├── architecture/           # _index.md + ADR-*.md
│   ├── epics/                  # _index.md + EPIC-*.md
│   ├── readiness-report.md
│   └── spec-summary.md
├── discussions/                # Discussion records (discussant output)
│   └── discuss-001..006.md
└── plan/                       # Plan artifacts (planner output)
    ├── exploration-{angle}.json
    ├── explorations-manifest.json
    ├── plan.json
    └── .task/
        └── TASK-*.json

Messages remain at .workflow/.team-msg/{team-name}/ (unchanged).

Session Resume

Coordinator supports --resume / --continue flags to resume interrupted sessions:

1. Scans .workflow/.team/TLS-*/team-session.json for status: "active" or "paused"
2. Multiple matches → AskUserQuestion for user selection
3. Audit TaskList — 获取当前所有任务的真实状态
4. Reconcile — 双向同步 session.completed_tasks ↔ TaskList 状态:
   • session 已完成但 TaskList 未标记 → 修正 TaskList 为 completed
   • TaskList 已完成但 session 未记录 → 补录到 session
   • in_progress 状态（暂停中断）→ 重置为 pending
5. Determines remaining pipeline from reconciled state
6. Rebuilds team (TeamCreate + worker spawns for needed roles only)
7. Creates missing tasks with correct blockedBy dependency chain (uses TASK_METADATA lookup)
8. Verifies dependency chain integrity for existing tasks
9. Updates session file with reconciled state + current_phase
10. Kick — 向首个可执行任务的 worker 发送 task_unblocked 消息，打破 resume 死锁
11. Jumps to Phase 4 coordination loop

Coordinator Spawn Template

When coordinator creates teammates:

TeamCreate({ team_name: teamName })

// Analyst (spec-only / full)
Task({
  subagent_type: "general-purpose",
  team_name: teamName,
  name: "analyst",
  prompt: `你是 team "${teamName}" 的 ANALYST。
当你收到 RESEARCH-* 任务时，调用 Skill(skill="team-lifecycle", args="--role=analyst") 执行。
当前需求: ${taskDescription}
约束: ${constraints}
Session: ${sessionFolder}

## 消息总线（必须）
每次 SendMessage 前，先调用 mcp__ccw-tools__team_msg 记录。

工作流程:
1. TaskList → 找到 RESEARCH-* 任务
2. Skill(skill="team-lifecycle", args="--role=analyst") 执行
3. team_msg log + SendMessage 结果给 coordinator
4. TaskUpdate completed → 检查下一个任务`
})

// Writer (spec-only / full)
Task({
  subagent_type: "general-purpose",
  team_name: teamName,
  name: "writer",
  prompt: `你是 team "${teamName}" 的 WRITER。
当你收到 DRAFT-* 任务时，调用 Skill(skill="team-lifecycle", args="--role=writer") 执行。
当前需求: ${taskDescription}
Session: ${sessionFolder}

Shared Spec Resources

Writer 和 Reviewer 角色在 spec 模式下使用本 skill 内置的标准和模板（从 spec-generator 复制，独立维护）：

Writer 在执行每个 DRAFT-* 任务前 必须先 Read 对应的 template 文件和 document-standards.md。 从 roles/ 子目录引用时路径为 ../specs/ 和 ../templates/。
