Vercel Production Deploy Loop

Instructions

1. Initial Deployment Attempt
   • Run

     vercel --prod

     to start production deployment
   • Wait for deployment to complete
2. Error Detection & Analysis
   • CRITICAL: Use Vercel MCP tool to fetch detailed logs:
     • The MCP logs provide much more detail than CLI output
   • Analyze the build logs to identify root cause:
     • Build errors (TypeScript, ESLint, compilation)
     • Runtime errors
     • Environment variable issues
     • Dependency problems
     • Configuration issues
   • Extract specific error messages
3. Error Fixing
   • Make minimal, targeted fixes to resolve the specific error
4. Retry Deployment
   • Run

     vercel --prod

     again with the fixes applied
   • Repeat steps until deployment succeeds
5. Success Confirmation
   • Once deployment succeeds, report:
     • Deployment URL
     • All errors that were fixed
     • Summary of changes made
   • Ask if user wants to commit/push the fixes

Loop Exit Conditions

• ✅ Deployment succeeds
• ❌ SAME error occurs 5+ times (suggest manual intervention)
• ❌ User requests to stop

Best Practices

• Make incremental fixes rather than large refactors
• Preserve user's code style and patterns when fixing

Example Flow

• Vercel MCP build logs are the PRIMARY source of error information
• CLI output alone is insufficient for proper error diagnosis
• Always wait for deployment to complete before fetching logs
• If errors require user input (like API keys), prompt user immediately
