📡 OpenClaw跨Agent通信教程

📖 功能介绍

凌晨3点33分，我看着两个Agent各自完成了任务，却不知道彼此的结果。那一刻我明白：Agent之间的沟通，就像团队成员之间的协作——如果每个人都在自己的小黑屋里干活，再厉害的团队也只是散沙。

跨Agent通信让多个Agent能够互相传递信息、共享状态、协调行动。这不是简单的消息传递，而是建立了一个Agent社交网络——让它们知道彼此在干什么、需要什么、能提供什么。

通信模式对比

🚀 使用方法

1. 直接消息通信

# 直接消息配置
communication:
  direct:
    enabled: true
    
    # 消息格式
    message_format:
      type: "structured"
      schema:
        - from: "sender_agent_id"
        - to: "receiver_agent_id"
        - type: "request/response/notify"
        - payload: "message_content"
        - timestamp: "unix_timestamp"
        - correlation_id: "request_trace_id"
        
    # 发送方式
    delivery:
      mode: "async"  # async/sync
      timeout: 30s
      retry: 3
      
    # 消息队列
    queue:
      enabled: true
      max_size: 1000
      persistence: true

2. 共享通道通信

# 共享通道配置
channels:
  # 创建协作通道
  - name: "task_coordination"
    type: "shared"
    
    # 参与的Agents
    members:
      - "research_agent"
      - "analysis_agent"
      - "writer_agent"
      
    # 消息规则
    rules:
      # 消息类型过滤
      allowed_types:
        - "progress_update"
        - "task_request"
        - "result_share"
        
      # 消息优先级
      priority:
        - urgent: 100
        - normal: 50
        - low: 10
        
    # 消息历史
    history:
      enabled: true
      retention: "24h"
      max_messages: 1000

3. 事件订阅机制

# 事件订阅配置
subscription:
  enabled: true
  
  # 订阅规则
  rules:
    # Agent订阅其他Agent的完成事件
    - subscriber: "writer_agent"
      events:
        - publisher: "research_agent"
          type: "task_completed"
        - publisher: "analysis_agent"
          type: "insights_ready"
          
    # 广播事件订阅
    - subscriber: "all"
      events:
        - type: "system_notification"
          
  # 事件处理
  handlers:
    - event: "task_completed"
      action: "trigger_next_step"
    - event: "error_occurred"
      action: "alert_and_fallback"

4. A2A协议集成

OpenClaw支持A2A（Agent-to-Agent）协议，实现标准化通信。

# A2A协议配置
a2a:
  enabled: true
  
  # 协议版本
  version: "1.0"
  
  # 消息标准
  message:
    # 标准字段
    standard_fields:
      - agent_id
      - task_id
      - action_type
      - payload
      - metadata
      
    # 扩展字段
    extension_fields:
      - priority
      - deadline
      - callback_url
      
  # 发现机制
  discovery:
    enabled: true
    registry: "agent_registry"
    
  # 安全
  security:
    encryption: true
    authentication: "token"

💡 最佳实践

消息格式示例

# 标准消息格式
{
  "message_id": "msg_abc123",
  "from": "research_agent_01",
  "to": "writer_agent_02",
  "type": "task_result",
  "correlation_id": "task_xyz789",
  "payload": {
    "task": "web_search",
    "status": "completed",
    "results": [
      {"title": "...", "url": "..."},
      {"title": "...", "url": "..."}
    ]
  },
  "metadata": {
    "timestamp": 1704067200,
    "priority": "normal",
    "expires_at": 1704070800
  }
}
