              "op": "sub",
              "value": "bot"
            }
          ]
        }
      ],
      "action": {
        "mitigate": {
          "action": "deny"
        }

🏥 Configuration Health

Doorman includes a built-in health checker that scores your configuration and provides recommendations:

vercel-doorman status  # Includes health score

Health Score Factors:

• Rule Naming - Proper ID formats and descriptive names
• Security Best Practices - Rate limiting, bot protection, etc.
• Performance Impact - Rule complexity and regex usage
• Maintainability - Disabled rules, duplicates, versioning

Score Ranges:

• 🟢 80-100: Excellent configuration
• 🟡 60-79: Good with minor improvements needed
• 🔴 0-59: Needs attention

🔒 Security Best Practices

Token Management

• Store API tokens in environment variables, never in code
• Set token expiration dates appropriately
• Use principle of least privilege for token scopes
• Regularly rotate API tokens

Rule Management

• Test rules in staging before production
• Keep backups of working configurations
• Use descriptive names and documentation
• Start with rules disabled, enable after testing

Team Collaboration

• Use version control for configuration files
• Document rule purposes and business logic
• Regular security audits of active rules
• Establish approval processes for rule changes

🚀 Advanced Features

Watch Mode for Development

vercel-doorman watch --interval 1000

Automatically syncs changes when you modify your config file. Perfect for rapid development and testing.

Backup Management

vercel-doorman backup                    # Create backup
vercel-doorman backup --list             # List backups
vercel-doorman backup --restore backup.json  # Restore backup

Multi-Format Export

# Generate team documentation
vercel-doorman export --format markdown

# Export for Terraform (conceptual)
vercel-doorman export --format terraform

# CI/CD integration
vercel-doorman export --format json --source remote

Configuration Health Monitoring

The health checker evaluates:

• Rule naming conventions
• Security coverage gaps
• Performance optimization opportunities
• Maintenance recommendations

🔧 Troubleshooting

Common Issues

"Project not found" error:

• Verify your Project ID is correct
• Ensure your token has access to the project
• Check that the project has Pro plan or higher

"Unauthorized" error:

• Confirm VERCEL_TOKEN is set correctly
• Verify token hasn't expired
• Ensure token has firewall permissions

Sync issues:

• Run vercel-doorman status to see what's out of sync
• Use vercel-doorman diff to see detailed changes
• Check for validation errors with vercel-doorman validate
