Vercel Production Deploy Loop

Instructions

When requested to deploy to Vercel production with automatic error fixing:

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

User: "Deploy to production and fix any errors"

• 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
