Deployment Health Monitor

{
  "description": "Monitor deployment status, error rates, and performance metrics, sending notifications for failed deployments or performance degradation. Tracks Vercel deployment health, monitors build success/failure rates, and provides alerts for deployment issues. Setup: Export 'export VERCEL_TOKEN=your_token' and 'export VERCEL_PROJECT_ID=your_project_id' (get from vercel.com/account/tokens and Vercel dashboard).",
