Integration with Other Skills

Call from Python

import subprocess
import json

def send_qywx_notification(webhook, content, image=None):
    """Send WeCom notification"""
    cmd = ["openclaw", "skill", "qywx-notify", "send"]
    cmd.extend(["--webhook", webhook])
    cmd.extend(["--content", content])
    
    if image:
        cmd.extend(["--image", image])
    
    try:
        result = subprocess.run(cmd, capture_output=True, text=True, check=True)
        return json.loads(result.stdout)
    except subprocess.CalledProcessError as e:
        print(f"Send failed: {e.stderr}")
        return None

Security Considerations

1. Protect Webhook URL: The Webhook URL contains sensitive information. Do not share it publicly.
2. Access control: Set minimum required permissions for the robot.
3. Content moderation: Avoid sending sensitive or inappropriate content.
4. Rate limiting: Comply with WeCom's message sending rate limits.
