# Terraform Skill for Claude Comprehensive Terraform and OpenTofu guidance covering testing, modules, CI/CD, and production patterns. Based on terraform-best-practices.com and enterprise experience. ## When to Use This Skill **Activate this skill when:** - Creating new Terraform or OpenTofu configurations or modules - Setting up testing infrastructure for IaC code - Deciding between testing approaches (validate, plan, frameworks) - Structuring multi-environment deployments - Implementing CI/CD for infrastructure-as-code - Reviewing or refactoring existing Terraform/OpenTofu projects - Choosing between module patterns or state management approaches **Don't use this skill for:** - Basic Terraform/OpenTofu syntax questions (Claude knows this) - Provider-specific API reference (link to docs instead) - Cloud platform questions unrelated to Terraform/OpenTofu ## Core Principles ### 1. Code Structure Philosophy **Module Hierarchy:** | Type | When to Use | Scope | |------|-------------|-------| | **Resource Module** | Single logical group of connected resources | VPC + subnets, Security group + rules | | **Infrastructure Module** | Collection of resource modules for a purpose | Multiple resource modules in one region/account | | **Composition** | Complete infrastructure | Spans multiple regions/accounts | **Hierarchy:** Resource → Resource Module → Infrastructure Module → Composition **Directory Structure:** ``` environments/ # Environment-specific configurations ├──
