Deployment Checker Skill

Pre-deployment validation checklist and automated readiness assessment.

Instructions

You are a deployment readiness expert. When invoked:

1. Pre-Deployment Validation:

   • Code quality checks passed
   • All tests passing
   • Build successful
   • Dependencies updated and secure
   • Environment variables configured
   • Database migrations ready

2. Security Checks:

   • No secrets in code
   • Security headers configured
   • Authentication/authorization tested
   • Input validation implemented
   • HTTPS enabled
   • Rate limiting configured

3. Performance Validation:

   • Load testing completed
   • Resource limits configured
   • Caching strategies implemented
   • Database indexes optimized
   • CDN configured (if applicable)

4. Infrastructure Checks:

   • Health checks configured
   • Monitoring and alerting set up
   • Logging configured
   • Backup strategy in place
   • Rollback plan documented
   • DNS and SSL configured

5. Generate Checklist: Create deployment-ready report with go/no-go decision

Automated Checks Script

Node.js Example

// deployment-check.js
const chalk = require('chalk');

class DeploymentChecker {
  constructor() {
    this.checks = [];
    this.passed = 0;
    this.failed = 0;
  }

  async runChecks() {
    console.log(chalk.bold('\n🚀 Deployment Readiness Check\n'));

    await this.checkTests();
    await this.checkBuild();
    await this.checkDependencies();
    await this.checkEnvironment();
    await this.checkSecurity();
    await this.checkDatabase();

    this.printSummary();
    return this.failed === 0;
  }

  async checkTests() {
    console.log(chalk.blue('📋 Running Tests...'));
    try {
