OctoGuard OpenClaw Security Supervision

Skill by ara.so — Security Skills collection.

OctoGuard (章鱼卫士) is a security governance and audit system designed specifically for OpenClaw AI agents. It provides real-time detection, policy control, and alert notifications for user dialogue commands, tool calls, and execution results. The system acts as a security gateway that intercepts dangerous operations before they execute, monitors token consumption, and maintains comprehensive audit logs.

What OctoGuard Does

• Policy-based Interception: Configure rules to block sensitive file access, dangerous operations, and high-risk behaviors
• Token Monitoring: Real-time tracking of token usage with threshold alerts
• Audit Logging: Record all OpenClaw events, allowed actions, and blocked attempts
• Visual Policy Management: Web-based dashboard for managing security policies
• OpenClaw Gateway Control: Monitor and control OpenClaw gateway status
• Multi-channel Alerts: Push notifications via DingTalk, WeChat Work, and Email
• Security Dashboard: Comprehensive visualization of OpenClaw security posture

Architecture

OctoGuard sits between external users and OpenClaw, intercepting all requests through a security policy engine before they reach the AI agent. It operates non-invasively without modifying OpenClaw's core functionality.

User Request → OctoGuard Security Gateway → Policy Engine → OpenClaw → AI Agent

      toolCall: tool_call,
      sessionId: session_id,
      timestamp: new Date()
    });
    
    if (evaluation.action === 'block') {
      // Log blocked attempt

      }
    ],
    logic: "sequential_within_5min"
  },
  action: "block",
  alertChannels: ["email", "dingtalk", "wechat"],
  message: "Potential data exfiltration attempt detected"
};

Alert Configuration

DingTalk Integration

// services/alerts/dingtalk.js
const axios = require('axios');

async function sendDingTalkAlert(event) {
  const webhook = process.env.DINGTALK_WEBHOOK;
  
  const message = {
    msgtype: "markdown",
    markdown: {
      title: `🚨 OctoGuard Security Alert`,
      text: `### Security Event Detected
      
**Type**: ${event.type}
**Policy**: ${event.policyName}
**Session**: ${event.sessionId}
**Time**: ${new Date(event.timestamp).toLocaleString()}

**Reason**: ${event.reason}

**Details**:
\`\`\`
${JSON.stringify(event.details, null, 2)}
\`\`\`

> Please review and take appropriate action.`
    }
  };
  
  await axios.post(webhook, message);
}

module.exports = { sendDingTalkAlert };

Email Alerts

// services/alerts/email.js
const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransporter({
  host: process.env.EMAIL_HOST,
  port: process.env.EMAIL_PORT,
  secure: false,
  auth: {
    user: process.env.EMAIL_USER,

      <pre>${JSON.stringify(event.details, null, 2)}</pre>
    `
  };
  
  await transporter.sendMail(mailOptions);
}

module.exports = { sendEmailAlert };

Policy Engine Implementation

// services/policyEngine.js
const db = require('../config/database');

class PolicyEngine {
  async evaluate(request) {
    // Load active policies sorted by priority
    const policies = await this.loadActivePolicies();
    
    for (const policy of policies) {
      const matches = await this.checkPolicy(policy, request);
      
      if (matches) {
        return {
          action: policy.action,
          reason: policy.message || `Blocked by policy: ${policy.name}`,
          policyName: policy.name,
          policyId: policy.id
        };
      }
    }
    
    return { action: 'allow' };
  }
  
  async loadActivePolicies() {
    const [policies] = await db.query(
      'SELECT * FROM policies WHERE enabled = true ORDER BY priority ASC'
    );
    return policies;
  }
  
  async checkPolicy(policy, request) {
    const conditions = JSON.parse(policy.conditions);
    
    // Check tool call conditions
    if (conditions.type === 'tool_call' && request.toolCall) {
      if (conditions.tool_name) {
        const toolNames = Array.isArray(conditions.tool_name) 
          ? conditions.tool_name 
          : [conditions.tool_name];
          
        if (!toolNames.includes(request.toolCall.name)) {
          return false;
        }
      }
      
      // Check pattern matching
      if (conditions.pattern) {
        const patterns = Array.isArray(conditions.patterns)
          ? conditions.patterns
          : [conditions.pattern];
          
        const content = JSON.stringify(request.toolCall.arguments);
        
        for (const pattern of patterns) {
          const regex = new RegExp(pattern, 'i');
          if (regex.test(content)) {
            return true;
          }
        }
      }
    }
    
    // Check user input conditions
    if (conditions.type === 'user_input' && request.userInput) {
      if (conditions.pattern) {
        const regex = new RegExp(conditions.pattern, 'i');
        if (regex.test(request.userInput)) {
          return true;
        }
      }
    }
    
    return false;
  }
}

module.exports = new PolicyEngine();

OpenClaw Gateway Control

// controllers/gatewayController.js
const axios = require('axios');
const { spawn } = require('child_process');

class GatewayController {
  async getStatus() {
    try {
      const response = await axios.get(
        `http://${process.env.OPENCLAW_HOST}:${process.env.OPENCLAW_PORT}/health`,
        { timeout: 5000 }
      );
      
      return {
        status: 'running',
        health: response.data,
        uptime: response.data.uptime
      };
    } catch (error) {
      return {
        status: 'stopped',
        error: error.message
      };
    }
  }
  
  async shutdown() {
    try {
      await axios.post(
        `http://${process.env.OPENCLAW_HOST}:${process.env.OPENCLAW_PORT}/admin/shutdown`,
        {},
        {
          headers: {
            'X-API-Key': process.env.OPENCLAW_API_KEY
          }
        }
      );
      
      return { success: true, message: 'OpenClaw gateway shutdown initiated' };
    } catch (error) {
      throw new Error(`Failed to shutdown gateway: ${error.message}`);
    }
  }
}

module.exports = new GatewayController();

Troubleshooting

Issue: Policies Not Blocking Requests

Check policy priority and conditions:

// Debug policy evaluation
async function debugPolicy(policyId, testRequest) {
  const policy = await db.query('SELECT * FROM policies WHERE id = ?', [policyId]);
  const conditions = JSON.parse(policy[0].conditions);
  
  console.log('Policy conditions:', conditions);
  console.log('Test request:', testRequest);
  
  const engine = require('./services/policyEngine');
  const result = await engine.checkPolicy(policy[0], testRequest);
  
  console.log('Match result:', result);
  return result;
}

Issue: Alerts Not Sending

Verify webhook configuration:

# Test DingTalk webhook
curl -X POST "${DINGTALK_WEBHOOK}" \
  -H 'Content-Type: application/json' \
  -d '{"msgtype":"text","text":{"content":"Test from OctoGuard"}}'

# Check email configuration
node -e "
const nodemailer = require('nodemailer');
const transporter = nodemailer.createTransporter({
  host: '${EMAIL_HOST}',
  auth: { user: '${EMAIL_USER}', pass: '${EMAIL_PASSWORD}' }
});
transporter.verify((err, success) => {
  console.log(err || 'Email config OK');
});
"

Issue: High Token Usage Not Alerting

Check threshold configuration:

// Verify token threshold settings
async function checkTokenThreshold() {
  const [settings] = await db.query(
    'SELECT * FROM token_thresholds WHERE enabled = true'
  );
  
  console.log('Active thresholds:', settings);
  
  // Manually trigger check
  const totalTokens = await db.query(
    'SELECT SUM(tokens_used) as total FROM token_usage WHERE timestamp > ?',
    [new Date(Date.now() - 3600000)] // Last hour
  );
  
  console.log('Current usage:', totalTokens[0].total);
  
  if (totalTokens[0].total > settings[0].threshold) {
    console.log('Threshold exceeded - alert should trigger');
  }
}

Issue: Database Connection Errors

Test database connectivity:

// Test database connection
const mysql = require('mysql2/promise');

async function testDatabaseConnection() {
  try {
    const connection = await mysql.createConnection({
      host: process.env.DB_HOST,
      user: process.env.DB_USER,
      password: process.env.DB_PASSWORD,
      database: process.env.DB_NAME
    });
    
    const [rows] = await connection.execute('SELECT 1 as test');
    console.log('Database connection successful:', rows);
    
    await connection.end();
    return true;
  } catch (error) {
    console.error('Database connection failed:', error.message);
    return false;
  }
}

Issue: Frontend Cannot Reach Backend

Verify CORS and API endpoint:

// backend/server.js - Add CORS middleware
const cors = require('cors');

app.use(cors({
  origin: process.env.FRONTEND_URL || 'http://localhost:5173',
  credentials: true
}));

// Frontend - Check API base URL
console.log('API Base URL:', import.meta.env.VITE_API_BASE_URL);

Performance Optimization

Cache active policies in memory:

// services/policyCache.js
class PolicyCache {
  constructor() {
    this.cache = null;
    this.lastUpdate = null;
    this.ttl = 60000; // 1 minute
  }
  
  async getPolicies() {
    const now = Date.now();
    
    if (!this.cache || !this.lastUpdate || (now - this.lastUpdate) > this.ttl) {
      const [policies] = await db.query(
        'SELECT * FROM policies WHERE enabled = true ORDER BY priority ASC'
      );
      
      this.cache = policies;
      this.lastUpdate = now;
    }
    
    return this.cache;
  }
  
  invalidate() {
    this.cache = null;
    this.lastUpdate = null;
  }
}

module.exports = new PolicyCache();
