> **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 Architecture Optimization

Orchestrate multi-agent architecture optimization: analyze codebase → design refactoring plan → implement changes → validate improvements → review code quality.

## Architecture

```
spawn_agent({ task_name: "team_arch_opt", message: "Execute skill team-arch-opt, args: task description" })
                    |
         SKILL.md (this file) = Router
                    |
     +--------------+--------------+
     |                             |
  no --role flag              --role <name>
     |                             |
  Coordinator                  Worker
  roles/coordinator/role.md    roles/<name>/role.md
     |
     +-- analyze → dispatch → spawn workers → STOP
                                    |
                    +-------+-------+-------+-------+
                    v       v       v       v       v
                 [analyzer][designer][refactorer][validator][reviewer]
```

## Role Registry

| Role | Path | Prefix | Inner Loop |
|------|------|--------|------------|
| coordinator | [roles/coordinator/role.md](roles/coordinator/role.md) | — | — |
| analyzer | [roles/analyzer/role.md](roles/analyzer/role.md) | ANALYZE-* | false |
| designer | [roles/designer/role.md](roles/designer/role.md) | DESIGN-* | false |
| refactorer | [roles/refactorer/role.md](roles/refactorer/role.md) | REFACTOR-*, FIX-* | true |
| validator | [roles/validator/role.md](roles/validator/role.md) | VALIDATE-* | false |
| reviewer | [roles/reviewer/role.md](roles/reviewer/role.md) | REVIEW-*, QUALITY-* | false |


## Pre-load (coordinator, before dispatch)

1. **Codebase docs**: If `.workflow/codebase/ARCHITECTURE.md` exists, read for module boundaries
2. **Specs (arch)**: `maestro load --type spec --category arch` — load arch constraints as shared context
3. **Specs (coding)**: `maestro load --type spec --category coding` — load coding constraints as shared context
4. **Wiki knowledge**: `maestro search "architecture optimization refactor" --json` — top 5 entries as prior context
5. All optional — proceed without if unavailable
## 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**: `TAO`
- **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: "arch-opt",
  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: arch-opt
requirement: <task-description>
inner_loop: <true|false>

## 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).`
})
```

**Inner Loop roles** (refactorer): Set `inner_loop` dynamically — `true` for single mode, `false` for fan-out/independent (parallel branches).
**Single-task roles** (analyzer, designer, validator, reviewer): Set `inner_loop: false`.

## User Commands

| Command | Action |
|---------|--------|
| `check` / `status` | View execution status graph (branch-grouped), no advancement |
| `resume` / `continue` | Check worker states, advance next step |
| `revise <TASK-ID> [feedback]` | Revise specific task + cascade downstream |
| `feedback <text>` | Analyze feedback impact, create targeted revision chain |
| `recheck` | Re-run quality check |
| `improve [dimension]` | Auto-improve weakest dimension |

## 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 |
| Completion action fails | Default to Keep Active |
| consensus_blocked HIGH | Coordinator creates revision task or pauses pipeline |
| Branch fix cycle >= 3 | Escalate only that branch to user, others continue |
| max_branches exceeded | Coordinator truncates to top N at CP-2.5 |
