# 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.
