Self-Healing System

This skill provides workflows for implementing autonomous system health monitoring, self-healing capabilities, resource optimization, and AI-powered recommendations.

System Health API

Create src/app/api/system/health/route.ts:

Vercel Cron Configuration

Add to vercel.json:

{
  "crons": [
    {
      "path": "/api/system/cron",
      "schedule": "0 2 * * *"
    }
  ]
}

Self-Healing Script

Create scripts/self-healing.js:

const { execSync } = require('child_process');

class SelfHealingSystem {
  async healthCheck() {
    const checks = { database: false, api: false, build: false, tests: false };
    
    try {

        headers: { 'Content-Type': 'application/json' },

      const result = await this.runOptimization();
      console.log('[Self-Healing] Cleanup result:', result);

    const analysis = await this.analyze();
    if (analysis?.recommendations?.length > 0) {

// Run on schedule
const system = new SelfHealingSystem();
system.runCycle().catch(console.error);
setInterval(() => system.runCycle().catch(console.error), 3600000); // Every hour

Cost Optimization Recommendations

Add to src/app/api/system/health/route.ts:

const costRecommendations: string[] = [];

// Database optimization
const dbSize = await prisma.$queryRaw`SELECT pg_database_size('your_database')`;
if (dbSize[0].pg_database_size > 1073741824) { // 1GB
  costRecommendations.push('Database exceeds 1GB. Consider archiving old data.');
}

// Storage optimization
const expiredSessions = await prisma.session.count({ where: { expiresAt: { lt: now } } });
if (expiredSessions > 10000) {
  costRecommendations.push(`${expiredSessions} expired sessions to clean up.`);
}

// API cost optimization
const apiCalls = await prisma.apiCallLog.count({ where: { createdAt: { gte: dayAgo } } });
if (apiCalls > 100000) {
  costRecommendations.push('High API call volume. Consider caching.');
}
