> 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

Role Registry

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