> Agent timeout: spawn_agent 异步执行且无内置超时 — 除明确短任务外一律 spawn_agent 后立即 wait_agent({ timeout_ms: 3600000 })（上限 1 小时）阻塞等待，绝不依赖 30000 默认值；timed_out: true 且 Agent 未完成时再次 wait_agent 续等，不丢弃。批量场景使用 spawn_agents_on_csv({ max_runtime_seconds: 3600, ... })。

Team Lifecycle v4

Orchestrate multi-agent software development: specification → planning → implementation → testing → review.

Role Registry

| Role | Path | Prefix | Inner Loop | |------|------|--------|------------| | coordinator | roles/coordinator/role.md | — | — | | analyst | roles/analyst/role.md | RESEARCH- | false | | writer | [roles/writer/role.md](roles/writer/role.md) | DRAFT- | true | | planner | roles/planner/role.md | PLAN- | true | | executor | [roles/executor/role.md](roles/executor/role.md) | IMPL- | true | | tester | roles/tester/role.md | TEST- | false | | reviewer | [roles/reviewer/role.md](roles/reviewer/role.md) | REVIEW-, QUALITY-, IMPROVE- | false | | supervisor | roles/supervisor/role.md | CHECKPOINT- | false |

Role Router

Parse $ARGUMENTS:

• Has --role <name> → Read roles/<name>/role.md, execute Phase 2-4
• No --role → @roles/coordinator/role.md, execute entry router

Shared Constants

• Session prefix: TLV4
• Session path: {run_dir}/work/team/
• CLI tools: maestro delegate --mode analysis (read-only), maestro delegate --mode write (modifications)
• Message bus: mcp__maestro__team_msg(session_id=<run-id>, ...)

Worker Spawn Template

Coordinator spawns workers using this template:

spawn_agent({
  subagent_type: "team-worker",
  description: "Spawn <role> worker",
  team_name: <team-name>,
  name: "<role>",
  run_in_background: true,
  prompt: `## Role Assignment
role: <role>
role_spec: <skill_root>/roles/<role>/role.md
session: {run_dir}/work/team
session_id: <run-id>
team_name: <team-name>
requirement: <task-description>
inner_loop: <true|false>
run_dir: <run-dir from team-session.json run.run_dir>

## Progress Milestones
session_id: <run-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final send_message.

Read role_spec file (@<skill_root>/roles/<role>/role.md) to load Phase 2-4 domain instructions.
Execute built-in Phase 1 (task discovery) -> role Phase 2-4 -> built-in Phase 5 (report).`
})

Supervisor Spawn Template

Supervisor is a resident agent (independent from team-worker). Spawned once during session init, woken via send_message for each CHECKPOINT task.

Spawn (Phase 2 — once per session)

spawn_agent({
  subagent_type: "team-supervisor",
  description: "Spawn resident supervisor",
  team_name: <team-name>,
  name: "supervisor",
  run_in_background: true,
  prompt: `## Role Assignment
role: supervisor
role_spec: <skill_root>/roles/supervisor/role.md
session: {run_dir}/work/team
session_id: <run-id>
team_name: <team-name>
requirement: <task-description>
run_dir: <run-dir from team-session.json run.run_dir>

## Progress Milestones
session_id: <run-id>
Report progress via team_msg at natural phase boundaries (context loaded -> core work done -> verification).
Report blockers immediately via team_msg type="blocker".
Report completion via team_msg type="task_complete" after final send_message.

Read role_spec file (@<skill_root>/roles/supervisor/role.md) to load checkpoint definitions.
Init: load baseline context, report ready, go idle.
Wake cycle: coordinator sends checkpoint requests via send_message.`
})

Wake (handleSpawnNext — per CHECKPOINT task)

send_message({
  type: "message",
  recipient: "supervisor",
  content: `## Checkpoint Request
task_id: <CHECKPOINT-NNN>
scope: [<upstream-task-ids>]
pipeline_progress: <done>/<total> tasks completed`,
  summary: "Checkpoint request: <CHECKPOINT-NNN>"
})

Shutdown (handleComplete)

send_message({
  type: "shutdown_request",
  recipient: "supervisor",
  content: "Pipeline complete, shutting down supervisor"
})

User Commands

| Command | Action | |---------|--------| | check / status | View execution status graph | | resume / continue | Advance to next step | | revise <TASK-ID> [feedback] | Revise specific task | | feedback <text> | Inject feedback for revision | | recheck | Re-run quality check | | improve [dimension] | Auto-improve weakest dimension |

Completion Action

When pipeline completes, coordinator presents:

request_user_input({
  questions: [{
    question: "Pipeline complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, clean up team" },
      { label: "Keep Active", description: "Keep session for follow-up work" },
      { label: "Export Results", description: "Export deliverables to target directory" }
    ]
  }]
})

Error Handling

| Scenario | Resolution | |----------|------------| | Unknown command | Error with available command list | | Role not found | Error with role registry | | CLI tool fails | Worker fallback to direct implementation | | Fast-advance conflict | Coordinator reconciles on next callback | | Supervisor crash | Respawn with recovery: true, auto-rebuilds from existing reports | | Supervisor not ready for CHECKPOINT | Spawn/respawn supervisor, wait for ready, then wake | | Completion action fails | Default to Keep Active |
