• After updating credentials

Error Handling

.env File Not Found

If the .env file doesn't exist, the skill will:

1. Report that no .env file was found
2. Suggest creating one from .env.example
3. Provide instructions on how to obtain credentials

Missing Required Variables

If required Cloudflare variables are missing:

1. Display which variables are missing
2. Provide links to obtain the credentials
3. Exit with error status

Placeholder Values Detected

If variables contain placeholder values like:

• your-*-here
• <your-*>
• xxxxx

The skill will warn that these need to be replaced with actual values.

Setup Instructions Provided

When variables are missing or have placeholders, the skill provides:

For Cloudflare:

• Link to Cloudflare Dashboard
• Link to API token generation
• Required permissions list

For Supabase:

• Link to Supabase Dashboard
• Navigation path to API settings
• Explanation of each key type and usage

Integration with Other Skills

This skill works well with:

• /dependencies - Check environment before installing dependencies
• /deployment - Validate configuration before deployment

Future Enhancements

Planned improvements:

• Validate format of environment variables (URL format, token length, etc.)
• Check for common configuration mistakes
• Suggest fixes for detected issues
• Support for multiple environment files (.env.development, .env.production)
• Export environment report to file
• Integration with CI/CD pipelines
