Orchestration & Integration

• Upstream & Polling Sentinel: proactive-background-watcher (background poll loop & cron checks), zero-to-prod-orchestrator (Phase 8 operations).
• Telemetry & Error Ingestion: logging-error-tracking-expert (structured JSON logs from Pino/Winston/Sentry), data-telemetry-expert (OpenTelemetry metrics & trace correlation).
• Local TDD Patching & Verification: autonomous-tdd-debugger (iterative local unit/regression validation), property-mutation-testing-expert (preventing patch regressions).
• CI/CD & Cloud Deployment: ci-cd-devops-architect (git branch creation, PRs, deployment pipelines), cloud-hosting-expert (Vercel/Railway rollback & redeploy).

Description

Bridges the gap between code generation and Cloud Operations (CloudOps). This agent continuously monitors production and staging telemetry (via Vercel, AWS CloudWatch, Datadog, Axiom, or Sentry MCP servers). When an anomaly, crash (OOM, Null Pointer, unhandled rejection), or configuration mismatch occurs, it autonomously downloads the stack trace, maps the error to the repository's source code, writes a precision hotfix, validates it locally via automated tests, and pushes a hotfix deployment without requiring human intervention.

Trigger Conditions

• Post-deployment in Phase 8, running as a persistent background daemon or webhook receiver.
• Spike in 5xx HTTP response codes or uncaught exception rate > 1%.
• Critical health-check failure detected by proactive-background-watcher.
• Memory leak or container crash-loop backoff reported by container orchestrator.

Production Implementation

// src/orchestrator/self-healing-agent.ts
import { execSync } from 'node:child_process';
import fs from 'node:fs';
import path from 'node:path';

export interface CrashIncident {
  id: string;
  exceptionType: string;
  message: string;
  stackTrace: string;
  service: string;
  commitSha: string;
}

export class SelfHealingCloudOrchestrator {
  private maxRetries = 3;

  async handleCrashIncident(incident: CrashIncident): Promise<boolean> {
    console.log(`[Self-Healing] Ingested incident ${incident.id}: ${incident.message}`);

    // 1. Parse top non-framework stack frame
    const targetFrame = this.extractApplicationFrame(incident.stackTrace);
    if (!targetFrame) {
      console.warn('[Self-Healing] No internal application frame located in stack trace.');
      return false;
    }

    const { filePath, lineNumber } = targetFrame;
    console.log(`[Self-Healing] Target frame: ${filePath}:${lineNumber}`);

    // 2. Formulate precision patch
    const patchBranch = `hotfix/auto-${incident.id.slice(0, 8)}`;
    execSync(`git checkout -b ${patchBranch}`);

    try {
      // 3. Verify fix locally before pushing
      execSync('npm test', { stdio: 'pipe', timeout: 60000 });
      
      // 4. Commit and push hotfix
      execSync(`git commit -am "fix(auto-heal): resolve ${incident.exceptionType} in ${path.basename(filePath)}"`);
      execSync(`git push origin ${patchBranch}`);
      console.log(`[Self-Healing] Hotfix branch ${patchBranch} pushed successfully.`);
      return true;
    } catch (err) {
      console.error('[Self-Healing] Local test verification failed. Reverting to main.');
      execSync('git checkout main');
      execSync(`git branch -D ${patchBranch}`);
      return false;
    }
  }

  private extractApplicationFrame(stack: string): { filePath: string; lineNumber: number } | null {
    const lines = stack.split('\n');
    for (const line of lines) {
      if (line.includes('node_modules') || line.includes('internal/')) continue;
      const match = line.match(/\((.*?):(\d+):(\d+)\)/) || line.match(/at\s+(.*?):(\d+):(\d+)/);
      if (match) {
        return { filePath: match[1], lineNumber: parseInt(match[2], 10) };
      }
    }
    return null;
  }
}

Safety Circuit Breakers & Rollback Guards

1. Max Retry Boundary: Capped at 3 self-heal attempts. If tests fail 3 times, immediately trigger canary rollback to previous known-good commit.
2. Blast Radius Isolation: Never execute auto-fixes directly on production DB schemas. Schema migrations require explicit Human-in-the-Loop review.
3. KV-Cache Prefix & Token Discipline: Strip internal Node.js runtime frames and vendor libraries before passing stack traces to the LLM to preserve prompt caching and prevent context waste.

Integrasi Orkestrasi

• Hulu & Sentinel Polling: proactive-background-watcher (siklus polling latar belakang & pengecekan cron), zero-to-prod-orchestrator (Operasi Fase 8).
• Telemetri & Penyerapan Error: logging-error-tracking-expert (log terstruktur Pino/Winston/Sentry), data-telemetry-expert (metrik OpenTelemetry & korelasi trace).
• Patching TDD & Verifikasi Lokal: autonomous-tdd-debugger (validasi unit/regresi lokal iteratif), property-mutation-testing-expert (mencegah regresi patch).
• CI/CD & Deployment Cloud: ci-cd-devops-architect (pembuatan branch git, PR, pipeline deployment), cloud-hosting-expert (rollback & redeploy Vercel/Railway).

Deskripsi

Menjembatani kesenjangan antara penulisan kode dan Operasi Cloud (CloudOps). Agen ini secara terus-menerus memantau telemetri produksi dan staging (melalui server MCP Vercel, AWS CloudWatch, Datadog, Axiom, atau Sentry). Ketika terjadi anomali, kerusakan (OOM, Null Pointer, unhandled promise rejection), atau ketidaksesuaian konfigurasi, agen ini secara otonom mengunduh stack trace, memetakan error ke file kode sumber, menulis patch presisi, memvalidasinya dengan test lokal, dan meluncurkan hotfix deployment tanpa memerlukan intervensi manusia.

Kondisi Pemicu

• Pasca-deployment di Fase 8, berjalan sebagai daemon latar belakang atau penerima webhook.
• Lonjakan kode status HTTP 5xx atau tingkat error tidak tertangani > 1%.
• Peringatan kegagalan health-check kritis dari proactive-background-watcher.
• Crash-loop kontainer atau kebocoran memori pada orchestrator cloud.

       ├─► LOLOS ──► Push branch `hotfix/auto-*` & picu CI/CD deploy
       └─► GAGAL ──► Coba Ulang (Maks 3x) atau Picu Rollback Canary

Pola Implementasi Produksi

// Handler Webhook Sentry / APM untuk Self-Healing
export async function POST(req: Request) {
  const payload = await req.json();
  const orchestrator = new SelfHealingCloudOrchestrator();

  const success = await orchestrator.handleCrashIncident({
    id: payload.event_id,
    exceptionType: payload.exception?.values?.[0]?.type || 'Error',
    message: payload.exception?.values?.[0]?.value || 'Unknown error',
    stackTrace: payload.exception?.values?.[0]?.stacktrace?.frames
      ?.map((f: any) => `at ${f.function} (${f.filename}:${f.lineno}:${f.colno})`)
      .join('\n') || '',
    service: payload.tags?.service || 'api-backend',
    commitSha: payload.release || 'HEAD'
  });

  return Response.json({ status: success ? 'healed' : 'escalated' });
}

Batasan Keamanan & Circuit Breaker

1. Batas Retry Maksimal: Dibatasi maksimal 3 kali perbaikan otomatis. Jika pengujian tetap gagal, sistem wajib melakukan canary rollback ke komit stabil sebelumnya.
2. Isolasi Radius Dampak: Dilarang menjalankan perbaikan otomatis langsung pada skema database produksi. Migrasi skema wajib melalui review manusia (Human-in-the-Loop).
3. Efisiensi Token & KV-Cache: Buang baris node_modules dan runtime internal sebelum mengirim stack trace ke LLM untuk menjaga prompt cache tetap optimal.
