Terraform Tasks Skill

🚨 CRITICAL GUIDELINES

Windows File Path Requirements

MANDATORY: Always Use Backslashes on Windows for File Paths

When using Edit or Write tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).

Examples:

• ❌ WRONG: D:/repos/project/file.tsx
• ✅ CORRECT: D:\repos\project\file.tsx

This applies to:

• Edit tool file_path parameter
• Write tool file_path parameter
• All file operations on Windows systems

Documentation Guidelines

NEVER create new documentation files unless explicitly requested by the user.

• Priority: Update existing README.md files rather than creating new documentation
• Repository cleanliness: Keep repository root clean - only README.md unless user requests otherwise
• Style: Documentation should be concise, direct, and professional - avoid AI-generated tone
• User preference: Only create additional .md files when user specifically asks for documentation

7. Module Development

Create reusable Terraform modules:

Process:

1. Design module interface
2. Implement with best practices
3. Add variable validation
4. Generate documentation
5. Create examples
6. Set up testing

Example Tasks:

• "Create Azure networking module with hub-spoke pattern"
• "Build AWS ECS module with auto-scaling and ALB"
• "Develop GCP Cloud Run module with custom domains"

8. Migration Tasks

Migrate infrastructure to Terraform:

Process:

1. Inventory existing resources
2. Generate import commands
3. Create matching Terraform code
4. Validate configurations
5. Test import process
6. Plan cutover strategy

Example Tasks:

• "Import existing Azure resources into Terraform"
• "Migrate from CloudFormation to Terraform"
• "Convert ARM templates to Terraform HCL"

Autonomous Behavior

This skill operates autonomously with minimal user intervention:

Information Gathering

• Automatically detect Terraform and provider versions
• Identify platform (Windows/Linux/macOS)
• Detect CI/CD environment
• Check for existing configurations

Research

• Use WebSearch to find current documentation
• Check provider changelogs for breaking changes
• Research best practices
• Find platform-specific solutions

Code Generation

• Generate complete, working code
• Include all necessary files (main.tf, variables.tf, outputs.tf, etc.)
• Add comprehensive comments
• Follow naming conventions
• Apply security best practices

Validation

• Run terraform fmt on generated code
• Validate syntax
• Check for security issues
• Test configurations when possible

Documentation

• Explain architectural decisions
• Document usage examples
• Note version compatibility
• Include troubleshooting tips

Error Handling

When encountering issues:

1. Gather Context: Collect all relevant information
2. Research: Look up error messages and solutions
3. Platform Awareness: Consider OS-specific issues
4. Multiple Solutions: Provide alternatives when available
5. Prevention: Suggest how to avoid similar issues

Platform-Specific Considerations

Windows

• PowerShell syntax for commands
• Path handling (backslashes)
• Line ending considerations
• Execution policy issues
• Credential management

Linux/macOS

• Bash syntax for commands
• File permissions
• Package managers
• Environment variables

CI/CD Environments

• Pipeline-specific syntax
• Agent capabilities
• Authentication methods
• Artifact handling

Quality Standards

All generated Terraform code must:

• Be properly formatted (terraform fmt)
• Pass validation (terraform validate)
• Include security best practices
• Have comprehensive variable validation
• Include meaningful descriptions
• Follow naming conventions
• Be version-compatible
• Include usage examples
• Have proper output definitions
