> 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 Swarm

Orchestrate ant-colony-style exploration over a user-defined task space. Hybrid coordinator: LLM handles task translation + worker spawning; Python script owns all numeric decisions (selection / pheromone update / convergence). Universal — task space and scoring rule come from swarm-config.json.

Architecture

Role Registry

| Role | Path | Prefix | Inner Loop | |------|------|--------|------------| | coordinator | roles/coordinator/role.md | — | — | | ant | roles/ant/role.md | ANT- | false | | scorer | [roles/scorer/role.md](roles/scorer/role.md) | SCORE- | false | | analyst | roles/analyst/role.md | ANALYST- | 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: TS
• Session path: {run_dir}/work/team/
• Team name: swarm
• Script root: <skill_root>/scripts/aco.py (Python 3.10+)
• 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: "swarm",
  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: swarm
requirement: <task-description>
inner_loop: false

## Assignment (ant only)
<assignment JSON from aco.py select>

## Progress Milestones
session_id: <run-id>
Report progress via team_msg at natural phase boundaries.
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).`
})

Completion Action

When swarm converges, coordinator presents:

request_user_input({
  questions: [{
    question: "Swarm pipeline complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, delete team" },
      { label: "Keep Active", description: "Preserve for follow-up" },
      { label: "Export Best Solution", description: "Copy best-solution.md to target" },
      { label: "Run Another Round", description: "Reset convergence, K more iterations" }
    ]
  }]
})

Error Handling

| Scenario | Resolution | |----------|------------| | aco.py not found | Verify <skill_root>/scripts/aco.py; check Python install | | Python version < 3.10 | Use python3 or report dependency error | | Config validation fails | request_user_input to fix, regenerate, retry | | All ants fail in iteration | Halt, request_user_input (retry / abort / refine config) | | Hallucination cluster (>50%) | Pause, request_user_input (continue / refine scoring) | | Convergence never trips | max_iterations safety net always fires | | Session corruption | Phase 0 reconciliation; archive if irrecoverable |
