    Example session with this skill installed

    Node.js Express API. Deployed on a VPS (Ubuntu). Here's the relevant code:

    // config.js

    const config = {
  db: 'postgres://admin:secret123@localhost:5432/myapp',
  port: 3000,
  env: 'production'
}

    // app.js (logger)

    const winston = require('winston');
const logger = winston.createLogger({
  transports: [new winston.transports.File({ filename: 'app.log' })]
});

process.on('SIGTERM', () => {
  console.log('shutting down');
});

    package.json has all dependencies listed. No Dockerfile. SQLite in dev, Postgres in prod.

    1. Factor 3 — Move db credentials out of config.js into process.env.DATABASE_URL
    2. Factor 11 — Replace File transport with Console transport (stdout only)
    3. Factor 9 — Complete the SIGTERM handler: close DB connections, drain in-flight requests

    About this skill

    Transform Your Apps into Cloud-Native Powerhouses

    Modern cloud infrastructure demands more than just code that "works locally." The 12-Factor Auditor is a specialized development tool designed to bridge the gap between local development and production-ready architecture. It performs a deep-dive analysis of your application's structure, configuration management, and operational patterns against the industry-standard methodology pioneered by Heroku.

    Detailed Compliance Auditing

    This skill goes beyond generic advice. It analyzes your specific language (Node.js, Python, Go, etc.) and deployment targets (Kubernetes, AWS Lambda, Docker) to identify architectural debt. It doesn't just tell you what's wrong; it provides a structured 12-point report including:

    • Precise PASS/FAIL Ratings: Transparent evaluation of every factor from dependencies to log management.
    • Actionable Remediation: Specific code and configuration fixes tailored to your codebase.
    • Risk Prioritization: Identification of the top 3 critical issues that most endanger production stability.
    • Compliance Scoring: A quantitative metric to track your progress toward cloud-native maturity.

    Why It Beats Manual Prompting

    While a general AI might give you a summary of the 12 factors, this skill enforces a rigorous, multi-phase audit workflow. It acts as an experienced SRE, specifically hunting for common pitfalls like "works on my machine" database discrepancies, improper SIGTERM handling, and hardcoded secrets that a standard prompt would likely overlook.
